8 Most Useful Bill Nye Videos To Watch

-Even if you are in college.

Bill Nye the Science Guy hasn’t produced new episodes since the end of Season 5 in 1998, but the show’s namesake host remains active in the promotion of science – and many of his videos remain outstanding content to watch even if you’re in College (or beyond).

Here at Biology Junction, our focus is on our own namesake subject, and that’s what this list focuses on – but for those of you who came here for a more general list, we’ve also included a few non-Biology videos down at the bottom. These videos are helpful regardless of what type of science you’re interested in, so everyone should take a look at them.

How We Chose These Videos

What good is a list without an explanation of how we made it? It wouldn’t be good science if we just threw it up here! Truth is, though, creating this list wasn’t very hard. First, we narrowed our list of sources to the best selections of Bill Nye videos – his classic show and the more-recent Greatest Discoveries series.

Next, we considered how useful each topic is to know. For students studying biology, it does no good to dive into topics more advanced than you’re ready for. Fortunately, most of Bill Nye’s videos are accessible even to beginners and provide a strong foundation for the topic. This ended up being a minor concern, but we were determined to go through the process.

Finally, we checked for the availability of videos. It doesn’t help to be told to watch a video if you can’t find it. A simple search should be enough to locate any of the videos on this list. If that fails, you should be able to get them from your library or preferred streaming service. We had a preference for videos that are freely available since budgets can be tight in college, but that didn’t significantly impact this list.

For our non-Biology videos, we used a similar process. Instead of emphasizing Biology, though, we decided to focus on the foundations of science and the information that’s most useful for everyone to know.

The Best Biology Videos From Bill Nye

Here are our top choices for Biology videos.

1: Biodiversity (S1 E9)

Biodiversity is the 9th episode of Bill Nye the Science Guy, and while it’s not the first to feature a Biology topic, we think it’s easily one of the most important episodes. This video focuses on more than just where things live – it also explains the concept of ecosystems and how important it is to have a variety of living things in each area.

Arguably the most important lesson of this episode is understanding that ecosystems are far more complex than figuring out which living things eat each other. Each part of an ecosystem affects all of the other parts. That’s why we have to be so careful when introducing plants or animals to new habitats – if the ecosystem isn’t ready to handle it, the whole thing could collapse.

A second lesson to focus on is how ecosystems can vary in size – and, in many cases, overlap each other. The Great Barrier Reef has its own ecosystem, but it’s part of the larger Pacific Ocean – and from there, it ultimately affects all life on the planet (even if the impact isn’t obvious).

Understanding biodiversity is critical to understanding biology as a whole. Life does not exist in a vacuum – not unless we put it there, anyway. Environments affect life and vice versa, and if you want to understand why something is the way it is, you have to look at the bigger picture.

2: Cells (S1 E17)

Cells are a fundamental component of life – and even if you think you understand them, it’s good to get a refresher on the topic before you start your studies. The main reason for this is that when we say something “affects an organ”, what we mean is “it affects certain cells of the organ in a particular way”.

For example, if you want to understand why too much alcohol can hurt the liver, you need to look at its impact on the cells of the liver. If you want to heal that liver when you’re done, you have to figure out what will encourage the cells to do that. Cells are the ultimate “micro” topic in biology, making the Bill Nye cells video easily one of the most important episodes for biologists to watch.

3: Food Web (S2 E6)

It’s hard to talk about biology without eventually talking about food – but how things get their food is a little more complicated. Only watch this video after you’ve watched Biodiversity, because that video provides some important groundwork for this topic.

The short version is that a food web describes how each part of an ecosystem gets its food. Ultimately, each living thing gets food either from other living things (like insects, plants, or rodents) or from the sun. Every living creature is ultimately dependent on plants – who, let’s not forget, are often nourished by the uneaten bodies of dead creatures.

(If you’re having flashbacks to a certain Disney movie about a young lion, there’s a reason for that – the Circle of Life, where living things depend on each other, is quite real.) Watch Food Web

4: Plants (S3 E3)

Given how important plants are to the previous video, now’s a good time to get a refresher on what they are, how they work, and what sort of impact they have on our lives. The crazy thing is how plants can synthesize their own food as long as they have sunlight, water, and carbon dioxide – though healthy soil and a few other nutrients certainly help.

Plants are also important for their impact on other aspects of Biology. For example, many medicines are made from plants or plant by-products and affect certain living things in specific ways. Once we understand how something works, we can start figuring out the best way to make use of it.

This is particularly helpful if you’re looking for a job with biology. Most of your work will likely involve seeing how various inputs (types of food, situations, etc.) affect living things, and plants will be a part of that. Studying life alone is a limited topic – but there are endless possibilities when studying the way things affect life.

5: Populations (S3 E19)

Populations are a group of similar living things living in a set area. We often refer to the population of the human race, but we may also talk about the population of a specific city, voting district, or another region.

In biology, the most important thing is understanding the populations of other living things, how they’ve changed over time, and what’s caused them to do so. As you learned in videos like Biodiversity and Food Web, living things all affect each other – and a sudden rise or drop in one population will ripple across the ecosystem and begin affecting other creatures.

There may not be as many fancy names or scientific terms here, but it’s still worth watching this video to ensure you have a good grasp of the fundamentals of biology.

6: Biology – Greatest Discoveries

Finally, Bill Nye’s Greatest Discoveries video on Biology rounds out the best videos on this topic with a look at 13 of the most important discoveries in biology. This includes a discussion on the discovery and impact of:

Microorganisms like bacteria, blood cells, and sperm
The Cell Nucleus that functions at the center point of most cells
Archaea, microorganisms that lack a cell nucleus but aren’t quite like bacteria
Cell Division, the process of growth and, in many ways, life itself
Sex Cells and how they differ from most other types of cells
Cell Differentiation and how different types of cells are made
Mitochondria, which are separate from cells but provide a critical function for metabolizing chemicals
The Krebs Cycle, which is how protein, fats, and sugars are turned into energy
Neurotransmission, which centralizes the body’s ability to control itself
Hormones, which are far more complicated than teenage urges
Photosynthesis, a process where light is turned into chemical energy
Ecosystems, a quick look back at larger ecological units
Tropical Biodiversity, or why warm and sunny places tend to have a much greater variety of life

Together, all of these are important for biologists to know.

The Best Overall Science Videos From Bill Nye

Whether or not you’re focused on biology, these videos are helpful for improving your overall understanding of science and are worth watching at any age.

1: Pseudoscience (S4 E9)

Many things that sound like science but aren’t. These things are often called pseudoscience, and learning how to recognize them is a valuable skill for any scientist. Fortunately, the entire topic can be brought down to a few simple principles.

First, science involves testing claims and ideas. If somebody says something can’t be tested, then it’s not within the realm of science and shouldn’t be treated as such. In those cases, it’s okay to say “perhaps we’ll never know for sure”.

Second, extraordinary claims require extraordinary proof. In other words, the more important your claim is, the more you need to support it with verifiable evidence. As the person making a claim, it is your job to provide corresponding proof. It is not the job of others to demonstrate that you’re right.

Furthermore, your results should be reproducible. Proper science only happens when someone tries to prove you wrong – fairly, of course – and fails to do so. If you repeat an experiment and keep getting results, you don’t have any answers – just more questions to ask.

Finally, you should learn critical thinking. This graphic is especially helpful for that and provides many questions that help you uncover the truth. For example, when presented with a claim, you may want to figure out who benefits from it, what the best/worst case scenarios of it are, where it might be a problem or solution, what might make it unacceptable, why people might need it, and how to approach it safely.

In many cases, purveyors of pseudoscience are simply looking to profit from your ignorance. As a scientist, it is your duty to see past things like that and uncover the truth. Watch Pseudoscience now.

2: Measurement (S5 E17)

Coming in as one of the last episodes ever aired, Measurement is something that honestly should have been one of the first videos they made. Measuring things is critical to the foundations of science as a whole. Proper measurements provide objective, verifiable information using a common set of standards, and it’s impossible to overstate how important this is.

There are a few important things to learn from this video, Measurement.

First, there are many ways of measuring things. You can measure units (members of a population), dimensions (the size of something), time (how long it takes something to happen), effects (what happens), and many other topics.

Second, you’ll learn why things should be measured. It’s not just to expand the amount of information we have, though that’s valuable in and of itself. Instead, measurements help us understand what’s different about two subjects so we can proceed to uncover why and how that difference occurred.

Taken far enough, this can lead to discoveries, such as finding that one person in a neighborhood didn’t get sick because they ate a particular herb.

Measurements are almost never a focus in and of themselves – but they’re a vital part of most scientific activities. If you want to be a scientist, then you’re almost certainly going to do a lot of measurements over the course of your career. That makes this innocent-sounding video one of the most helpful episodes of Bill Nye.

Significance of Editing and Proofreading Your Biology Research Essay

A review essay for the biological sciences serves to discuss and synthesize key findings on a particular subject

Seasoned writers know that the most critical stage of writing academic papers is always editing. While editing, you catch most of the standard mistakes and polish your papers. Properly polished papers often receive much better grades than raw ones because the general neatness of your paper and correct grammar are what most attract the reviewer’s attention.

Suppose you want to create a decent biology research essay, which is a significant paper for your academic performance. In that case, you must dedicate enough time for thorough editing and utilize some effective hacks and tips. We have gathered the most valuable advice for proper proofreading: with our guidance, you will be able to elevate your writing to the next level. If you are still not confident in your abilities to write close-to-perfect papers, contact the science essay writing service for urgent assistance.

Why Proofreading Is So Important

Proofreading is reviewing a work with a critical eye for typos, grammatical mistakes, and punctuation issues. A typical proofreader’s duties include making sure all citations and formatting are consistent and pointing out any instances of ambiguity or misinterpretation. Proper proofreading aids in fixing mistakes such as run-on phrases, fragmented sentences, and comma splices. Little mistakes may slip your mind while you are engrossed in your research and writing. Proofreading is a great way to catch and repair these mistakes.

To be clear, proofreading is not the same as editing. Editing and proofreading are sometimes confused for one another by researchers and PhD candidates. Keep in mind that editing is done before proofreading, and the aim is to make the research paper more explicit by fixing spelling and grammar mistakes and ensuring it is easy to read.

Tips on Proofreading Your Biology Paper

1 – Verify Your Biology Research

Proofreading and editing means not only finding typos and errors in spelling but also applies to finding logical flaws. The most essential part of your biology paper is research, and we recommend starting by rechecking each number and statement from your study. Otherwise, you risk writing the whole paper based on inaccurate facts, which can disaster your academic performance.

2 – Understand the Difference

When you edit your work, you check it for logic, coherence, structure, and argument errors. Grammar, spelling, punctuation, formatting, and consistency are all aspects of a paper that should be carefully examined during proofreading. Editing focuses on the overall structure, whereas proofreading is more concerned with the specifics.

3 – We Recommend Always Starting with Editing

It is standard practice to modify a document first before moving on to proofreading. Doing so can save you the trouble of going back and addressing tiny mistakes that can easily be edited out.

Before you revise your work:

1. Give it a thorough and critical read-through.

2. Make sure it has a clear objective, research question, or hypothesis.

3. Check that the journals and your field’s specific guidelines for paper format and structure are followed.

We also recommend verifying that you have adequately introduced your study topic and provided the necessary background information in your work. Also, check that your work is well-organized and clearly displays your techniques, findings, and discussion. It would also be smart to remember that you need to include credible sources to back up your statements and conclusions throughout the paper and check that the manuscript acknowledges the limitations and consequences of your research.

4 – Listen to Feedback & Use Advanced Writing Tools

When you edit your work, you risk missing typos or weak points in your argument. Because of this, you need to use editing tools and comments to improve your paper. Software or online platforms exist to assist with many aspects of document editing, such as checking for plagiarism, readability, word count, and style. Another option to help you find typical mistakes in your writing is to utilize a grammar or spell checker. On the other hand, you shouldn’t put all your faith in these tools—they may miss inevitable subtle mistakes or details in your paper. The best way to improve your paper is to get comments from people you respect, such as classmates, bosses, or mentors. They will be able to provide you with honest, helpful criticism. Pay attention to their feedback and change your paper based on what they say.

5 – Apply Best Proofreading Techniques

When you proofread your work, you run the risk of missing typos or grammatical mistakes that you’ve grown accustomed to. Use these proofreading approaches to make your work more correct.

To catch typos or strange phrasing you would miss when reading it silently or on your computer, you could print a copy of your paper and read it out loud. Consider reading your paper backward: it will force you to concentrate on the structure and spelling of each word rather than the overall meaning or flow of the sentences. A checklist or guide can remind you what to search for and how to fix any mistakes or inconsistencies in your paper, while a ruler or finger can assist you in avoiding skipping or repeating lines or words.

6 – Double-Check Numbers, References and Symbols

Such mistakes will easily catch the attention of reviewers but can be hard to spot for an average writer. You write this number once at the start and never return to recheck it because you are sure that the stated information is absolutely correct. The standard proofreading practice is double-checking all facts and accurate information in your biology research.

7 – Focus on One Type of Error at a Time

Keep in mind that academic writing proofreading is no picnic. As you go through your text, focus on fixing one typical error type at a time. Checking for spelling, grammar, or punctuation errors could be a good place to start. This method can help you avoid accidentally missing potential mistakes.

The Bottom Line

Writing an excellent biology research essay requires diligence, perseverance, and proper proofreading. We recommend not only looking for spelling errors, but double-checking each number in your final draft and each fact from your study. The outstanding research paper is a balanced combination of accurate information, perfect writing, and impeccable quality, and thorough proofreading can help you guarantee all of these.

How Much of the MCAT Is Biochemistry?

In this brief guide, we are going to answer the question “How much of the MCAT is biochemistry?” We will introduce you to each of the MCAT sections, the main concepts you will need to learn, and some tips for studying biochemistry.

How Much of the MCAT is Biochemistry?

Biochemistry comprises approximately 25% of the MCAT, with 25 to 35 questions covering biochemistry in two of the four sections of the exam.

The Medical College Admission Test (MCAT) is a standardized test administered to individuals who wish to attend medical school in the United States. Almost all American medical schools require MCAT scores from applicants interested in pursuing careers as physicians.

Therefore, the MCAT is an extremely important exam, and both schools and applicants take it seriously. Members of the Association of American Medical Colleges and the American Association of Colleges of Osteopathic Medicine require MCAT scores from their applicants.

The history of the MCAT is quite long. MCAT Test preparation administrations began in the 1920s when standardized intelligence tests became immensely popular in the United States. Medical school administrators were concerned about the high dropout rate among medical students and decided to design a standardized test to assess readiness for medical school.

Dropout rates dropped dramatically after the implementation of this standardized test, and most medical schools adopted it as part of their admissions process.

The MCAT content assesses several areas. The first, of course, is the basic knowledge of the physical sciences and biology. The test also evaluates the applicant’s analytical and critical thinking skills, presenting various passages and arguments that the examinee must analyze during the test.

The MCAT also assesses reading comprehension and communication skills, which are vital for clinicians.

The modern MCAT is a computerized test, although it is not adaptive like the Graduate Record Examination (GRE). This means that examinees can return to a section once they have completed it, as the questions are set and static.

The MCAT takes around five hours to complete, including breaks, and is administered in secure testing centers so applicants have quiet, distraction-free spaces to work.

MCAT Sections

There are four sections on the MCAT. The first tests the applicant’s knowledge of the physical sciences and also challenges the applicant to use their problem-solving skills.

The Verbal Reasoning section, Part Two, provides passages for test-takers to read and analyze, followed by a series of multiple-choice questions that test the applicant’s ability to comprehend and synthesize information. For those looking for additional support, a college paper writing service can help improve writing and analytical skills.

The third section is a writing sample, in which the applicant responds to two short prompts that assess their communication skills and logical thinking. Finally, the life sciences section covers basic topics in biology.

Chemical + Physical Foundations of Biological Systems

The first section of the MCAT focuses on the physical sciences, specifically general chemistry and physics. It covers content in the following proportions:

30% General Chemistry

25% Biochemistry

25% Physics

15% Organic Chemistry

5% Biology

This section lasts 95 minutes and includes 15 standalone questions and 10 passages, each followed by 4 to 7 questions. To prepare for the chemistry portion, examinees need a strong grasp of the periodic table, chemical processes, and molecular bonding. The physics portion requires understanding fundamental physical laws and concepts such as motion, energy, light, and atomic structure.

Critical Analysis + Reasoning Skills

The CARS section is significantly more challenging than SAT-style reading comprehension and the verbal section of the old exams. This section covers:

50% humanities

50% social science

You are not required to have any outside knowledge; everything you need to know to answer the questions will be provided in the passages. You will have a total of 90 minutes to work through nine passages with a total of 53 questions. If you’re struggling with essay writing as part of your test preparation, a paper writing service can help you improve your skills.

In this section, no specific factual knowledge is required. Rather, the questions are designed to test reading comprehension, critical and logical thinking, and analytical skills. In general, test takers prepare for this section of the MCAT primarily by taking practice exams.

Biological + Biochemical Foundations of Living Systems

This section covers:

65% Biology

25% Biochemistry

5% General Chemistry

5% Organic Chemistry

As with the first science section, you’ll have 95 minutes to answer 15 discrete questions and 10 passages with 4 to 7 questions each. The topics in this section vary widely, from enzyme structure to evolution. Test-takers require a thorough understanding of molecular biology, including the structure and function of DNA, as well as microbiology, including the characteristics of viral, bacterial, and eukaryotic cells.

In addition, examinees should be familiar with all major biological systems of larger animals. Finally, organic chemistry topics range from covalent bonds to the characteristics of biological molecules.

MCAT Scores

Each section of the MCAT allows a student to score between a minimum of 118 points and a maximum of 132 points. For the total sum of the four sections, a student can achieve a score ranging from a minimum of 472 to a maximum of 528.

You may have heard scores like 23 or 31 mentioned in the past. However, it’s important to clarify that these scores were used before the MCAT underwent its most recent change in 2015. Currently, all students applying to medical school are doing so with the new scoring system.

What is considered a good GMAT score?

The average for the total MCAT score is 510-511.

The average total MCAT score is 510-511. However, for the most accurate estimate, you should check directly with the programs. Especially for those who must juggle the MCAT alongside other jobs, it helps to know how much effort and time to put into preparing for the exam.

Here are some important questions to consider before beginning your research.

What MCAT Scores Do You Need for Acceptance?

To determine the MCAT score you need, it’s essential to have a target score in mind. Start by contacting the admissions office of the medical schools you’re interested in to request their preferred cutoff score. If the school doesn’t provide a specific cutoff, you can find the average GPA and MCAT scores for accepted students here.

Keep in mind that some schools may use your MCAT scores for course placement or scholarship decisions. In such cases, aiming for a score higher than the minimum requirement may increase your chances of receiving additional benefits.

How can I prepare for the MCAT?

To excel on the MCAT® Biology exam, start by gathering detailed information about the test. This knowledge will help you craft an effective study plan. The MCAT is a standardized exam with primarily multiple-choice questions. Besides biology concepts, it also assesses your understanding of physical sciences, verbal reasoning skills, and writing abilities. There are many MCAT preparation courses available online and in person.

Exploring the Biochemistry Section

For specific details about the MCAT biochemistry section, visit the Association of American Medical Colleges website. The site provides a comprehensive overview of the content covered in the biology and chemistry sections of the MCAT.

Importance of Early Preparation

A high score on the MCAT can significantly enhance your chances of getting accepted into your desired medical school. Therefore, it is beneficial to begin your study preparation early. Many experts recommend starting at least three months before the exam date.

Additionally, if you find yourself struggling with other academic tasks, you might consider using an online paper writing service to help manage your workload. Dedicating substantial study time each day can ensure thorough preparation, allowing you to cover all necessary concepts and avoid last-minute cramming, which is generally ineffective for achieving a high score.

Utilizing Study Guides and Practice Tests

Consider obtaining a copy of the Official MCAT Exam Guide, available on the Association of American Medical Colleges website. This guide contains content and questions similar to those on the actual MCAT, along with answers and detailed explanations. It also offers tips for answering questions correctly and insights into how a strong MCAT score can impact medical school acceptance.

Practice tests are an essential tool for preparing for the MCAT® Biology section. The Association of American Medical Colleges website offers practice tests, and additional tests can be found on other preparatory websites and in study guides. If you opt for an MCAT® Biochemistry Prep course, practice tests, and expert commentary are often included in the package.

Vocabulary Building Techniques in Science

Teaching Strategies for Making Connections With Science Concepts

A multidimensional approach to supporting students’ learning related to science vocabulary is shown using graphic organizers, differentiated instruction, and more.

Vocabulary building in science is a difficult task for students and requires a variety of teaching strategies by teachers. A typical science textbook introduces 10 to 30 new vocabulary words every chapter. Students are faced with making sense of these new science words and connecting them to concepts in a relatively short period. Students are also required to connect these new words with information gained from prior knowledge and experiences in science.

Science vocabulary building requires more than rote memorization as one teaching strategy, which only leads to short-term knowledge gain. Since long-term knowledge gain of vocabulary is the goal, students must be exposed to all new science words at least six times in different contexts (“Learning Vocabulary Through Reading,” American Educational Research Journal, Volume 21 Issue 4, 1984).

Examples of exposure to science words in different contexts include:

Reading
KWL Organizers
Venn Diagrams
Videos
Hands-on, Minds-on Explorations
Explaining Using Own Terms
Illustrations
Vocabulary Lists

Graphic Organizers

The following are types of graphic organizers used as teaching strategies to help students learn science words in different contexts for vocabulary building.

Concept Definition Map – using an essential science vocabulary word placed in the center of the graphic that supports a science concept. One example is thermal energy. The descriptive words associated with this vocabulary word are written in boxes surrounding the concept word. For example – heat, energy transformation, etc. This concept definition map technique helps students develop a definition of the vocabulary word and make connections with prior knowledge and experiences, similar to how a PhD research proposal writing service helps scholars define and connect their research ideas.

Vocabulary Concept Cards – in this vocabulary-building technique students select a science word from the vocabulary list and write the word on one side of an index card. Then divide the other side of the index card into quadrants.

The left-hand side quadrants are:

What the word is using own words
What the vocabulary word is not using own words

The right-hand quadrants are:

Examples (next to what the word is) using drawings, words, or sentence
Definition (next to what the word is not) provided by textbook or teacher-provided resource

Other Graphic Organizers – examples of these vocabulary builders include KWLs, Venn Diagrams, Concept Maps, Mind Maps, or Word Maps.

Teaching Strategies

Additional teaching strategies that support students when learning science vocabulary words include a science nature journal, writing in science, and a science newsletter project. These three alternatives involve students writing stories that incorporate science words in a manner that helps them develop a better understanding of the science concepts behind the words.

Differentiated Instruction

Every science classroom has students with a wide range of abilities. This is the challenge all teachers face and the following are teaching strategies to address these concerns.

Differentiate Vocabulary Lists – this vocabulary building technique addresses the needs of all students including gifted and talented or advanced students, struggling students, students with learning disabilities, and all other students. This is accomplished by dividing the vocabulary list into three sections.

These sections are:

Science words all students must know in a chapter
Enrichment vocabulary words for gifted and talented students who need the extra challenge
Essential words struggling students and students with learning disabilities must learn to remain on grade level

Individualized Vocabulary Lists – this vocabulary-building technique allows students to create their list. The list must include essential science words deemed necessary by the teacher and then students select additional vocabulary words from a list of enrichment words. This technique provides students with extra credit for learning enrichment words. This works well in a class with several gifted or advanced students who want the challenge.

Alternative Assessments – differentiated or individualized vocabulary requires alternative assessments. Teachers allow students to draw pictures, write descriptions, or explain definitions based on the ability level of the student. A simple rubric is then used to determine the mastery level of each of the science words.

Making Connections with Vocabulary Building in Science

Traditional science vocabulary building involves rote memorization and recall of vocabulary, which only leads to short-term gains. However, building vocabulary knowledge requires a multi-dimensional approach. Science is a subject best learned through hands-on, minds-on experiences and this lends itself to teaching strategies that use a variety of learning strategies. Because of the way science is typically taught, students have the opportunity to view and learn science vocabulary in many contexts.

Conclusion

Building vocabulary in science is a complex task that requires more than just rote memorization. Effective vocabulary teaching strategies must incorporate diverse methods, including graphic organizers, differentiated instruction, and contextual exposure. Students benefit from experiencing new science terms multiple times in different contexts, which helps them connect these terms with prior knowledge and deeper science concepts.

By using tools like concept definition maps, vocabulary concept cards, and differentiated vocabulary lists, teachers can cater to the varying needs of all students. Additionally, integrating creative projects like science journals and newsletters further solidifies students’ understanding by encouraging them to use new vocabulary in meaningful ways.

Overall, a multidimensional approach to vocabulary building in science not only aids in short-term retention but also fosters long-term comprehension and application of scientific concepts.

Study Skills for College Science: How to Prepare for Science Exams

For many university students, college-level science courses are very difficult. One key to success is to learn how to properly study all of the course material.

Most universities require that their students take some college-level science courses to be eligible to graduate. Others plan on future careers in nursing, and medical fields, where doing well in these courses is required to get into competitive and selective majors (and into good jobs upon graduation). Regardless, these courses require discipline, good study habits, and perseverance to succeed.

The study skills offered here are designed to help make the best use of one’s time in preparing for exams and retaining information. These tips work for science courses in geology, biology, chemistry, physics, anatomy, and physiology, among other university disciplines.

Using Notecards for Science Course Material

One common error made by university students in science classes is spending too much time making notecards. If all of one’s study time is spent making notecards, there is very little time left to cram notecard material or to go through large packs of index cards. While rewriting notes onto index cards or notecards helps some with recalling information, the likelihood of retaining almost everything rewritten is minimal. If anything, some students may be more focused on getting notecards written rather than watching what is being written. For those struggling to manage their study time effectively, using an essay writing service can be a beneficial alternative, allowing them to focus on learning rather than getting bogged down by excessive note-taking.

Instead, index cards are more effective in preparing for science exams. Prefixes (examples: mono-, poly-) and formulas are tools one can readily memorize and take into a test to help find correct answers among multiple-choice options or problem-solving sets. Likewise, short definitions and vocabulary words can go on cards. The main things to keep in mind are:

keep lots of white space (space with no writing) as too much text distracts the eye and makes it more difficult to recall the information
try writing in color pens, markers
make index cards up as the material is covered in the textbook or class lecture then leave all the index cards to be made the week of an exam

Mnemonics for Science Courses

Another thing a student could use to retain all the course information from a science course is the tool called a mnemonic. Short phrases, acronyms, and sequences of letters can help recall a sequence of words or the ordering/arrangement of a list of words. Examples for the sciences include:

HOMES – the American Great Lakes: H(Huron), O (Ontario), M (Michigan), E (Erie), S(Superior)
My Very Excellent Mother Just Served Us Nine Pizzas (Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune and the former planet, Pluto)

With these previous examples, the words “homes” and the phrase “my very excellent mother just served us nine pizzas” expand outward. In the case of “homes,” the word uses the first letter of each of the five lakes. In the planets’ case, the first letter of each word matches the first letter in the corresponding planet name. What is good with this mnemonic example is the fact that not only does the first letter in each word match the first letter of the corresponding planet, but the entire list is in close order to their proximity to the sun, as Mercury is the closest planet and “my” is the first word in the phrase.

While these examples are more often taught and used in American grade schools rather than in college and university-level science courses, the same principles apply. Mnemonics are particularly useful for human anatomy and physiology courses, where bones or nerves in a particular region of the human body have unique names, sometimes quite close in spelling. Sayings and acronyms make it easier to recall a listing and sometimes the order of the list.

Study Groups for Science Class

In addition to making notecards and mnemonics alone, science students may benefit from studying in pairs or groups with classmates. Before chemistry or biology exams, a group could meet to quiz one another.

Likewise, groups can come in handy for science courses where the professors/course instructors have provided study guides. A group can divvy up a packet so that everyone benefits from a completed study guide, without as much individual investment of time and work.

That way too, if any vocabulary words are unclear or test prep questions that are confusing, the group can collectively work together to find the answer or ask the professor for help. Working together on review packets for science classes more than any other discipline is a good use of time and resources, as the packets tend to be more involved with lots of vocabulary.

Lastly, explaining science concepts, systems or processes (like the Krebs cycle or mitosis) aloud is excellent studying practice, as teaching concepts to others and speaking the stages out loud helps with retention and recall of concepts on test day.

Textbook and Lecture Note Review for Science Class

Along with good group studying sessions, university students enrolled in science courses ought to practice good textbook and lecture note review too. Taking detailed notes in margins, in diagrams and graphics, and with highlighters helps sort out the most important and the most difficult concepts in a clear manner.

One thing that is particularly true with science courses is the importance of reading ahead. Even if the professor does not assign class reading in advance, one should skim-read the next section or chapter so that there is a baseline understanding of a concept before it is covered in class. This way, one can focus more on the dialogue in the lecture and what the instructor has to say rather than trying to cram every little item into notes taken during class.

In closing, strong note-taking, notecard-making, textbook reviewing, and group study habits can help many achieve improvement in college-level science courses, whether the course is in physics, archaeology, or biology for example. The key is to use time efficiently and effectively and find a way to store all the material and recall it come test day.
