Scientist Brochure Webquest

 

Famous Scientists Webquest

Introduction

     The government needs a brilliant scientist to head its new department: The Scientific Masters of Applied Research and Technology (SMART). Using an amazing new technology, you can actually become another person with injections of their DNA! (This is “science fiction”!) You will be going on a job interview for this most prestigious job! You need to prepare for the interview by compiling an awesome brochure for your resume. After all interviews have been completed, the class will display the scientists who will potentially become the new National Director of SMART!

The Task

You are to create a brochure with information about your scientist. Below is a list of information you should include in the brochure:

  • educational background
  • previous job experience
  • special interests, hobbies
  • contributions to the scientific world
  • organization memberships
  • special honors awarded

Resources

     You may use internet resources as well as library resources to gather information about your men and women scientists.  Below is a list of helpful websites to use for your research:

The Process

     FIRST, you will choose one of the following scientific fields to research:

  • Biology

  • Environmental science

  • Zoology

NEXT, choose one scientist to research.  Print or write out the resume and complete the       information about your scientist.

BIOLOGISTS
Alice Catherine Evans
Stephen Jay Gould
Rosalind Franklin
Barbara McClintock
Lynn Harper
Myra Adele Logan
Angella Ferguson
Gertrude B. Elion

ZOOLOGISTS/ ENVIRONMENTALISTS
Rachel Carson
Aldo Leopold
Margaret Morse Nice
Dian Fossey
Jane Goodall
Eugenie Clark

    THEN, using the resume worksheet, complete the information as described below to assist you in completing your bibliography.

  • Name: (The name of the scientist you researched)

  • Country of Birth: (Where the scientist was born)

  • Date of Birth/Date of Death: (birthday and date deceased if applicable)

  • Education: (List the names of colleges attended and majors studied during college)

  • Job Experience: (List relevant job experience)

  • Awards Received: (What awards has your scientist received?)

  • Contributions to the Scientific World: (What has your scientist done help the world be a better place?)

  • Interests/Hobbies: (Scientists have other interests; list them if you can find what else they may be interested in)

  • Miscellaneous: (You may add any other interesting information to your biography such as books your scientist has written, memberships to scientific societies, etc.

    Finally, create a brochure (flyer) using the information from your scientist’s resume.  Be creative with the brochure and include pictures.

secrets of straight-a students

  1. Set priorities. There is no interruption of study time with TV, phone calls, snacks, etc.
  2. Study anywhere or everywhere. Keep a regular time everyday for studying and utilize extra time at work or play to study.
  3. Get organized. Keep an organized planner and notebook with all assignments and an organized study area with all supplies. Make sure to have all assignments and needed materials with you each time you go to class.
  4. Learn how to read. The secret of good reading is to be an “active reader.”
  5. Schedule your time. Procrastination is a student’s best enemy.  Don’t wait to the last minute to complete assignments or to study.
  6.   Take good notes – And use them! Always read the chapter, but listen and copy notes in class and then reread and recopy your notes each day.
  7.  Clean up your act. Neat assignments are more likely to get higher grades than sloppy ones.
  8. Speak up. Participate in class by asking questions and showing intellectual curiosity.
  9.  Study together.
  10. Test yourself. Make up and answer possible test questions or write out answers to chapter objectives.
  11. Do more than you are asked. Part of learning is practicing and the more you practice, the more you learn.

The most important ‘secret’ of the super-achievers is not so secret.  For almost all straight-A students, the contribution of their parents is crucial …Parents impress the lesson of responsibility on their kids.

Seed Germination & Detergents

 

Detergent & Seed Germination

Introduction:

Seeds come in different sizes, shapes, and colors. Some are edible and some are not. Some seeds germinate readily while others need specific conditions to be met before they will germinate. Within every seed lives a tiny plant or embryo.The outer covering of a seed is called the seed coat. Seed coasts help protect the embryo from injury and also from drying out. Seed coats can be quite thin and soft as in beans or very thick and hard as in locust or coconut seeds. Endosperm, which is a temporary food supply, is packed around the embryo in the form of special leaves called cotyledons or seed leaves. These generally are the first parts visible when the seed germinates. Plants are classified based upon the number of seed leaves (cotyledons) in the seed. Plants such as grasses and grass relatives can be monocots, containing one cotyledon. Dicots are plants that have two cotyledons.

 Seeds remain dormant or inactive until conditions are right for germination. All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while other require darkness to germinate.When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat. The embryo’s cells start to enlarge and the seed coat breaks open and root or radicle emerges first, followed by the shoot or plumule which contains the leaves and stem.

Many factors contribute to poor germination. Over-watering results in a lack of proper oxygen levels. Planting seeds to too deep results in the seed using up all of its stored energy before reaching the soil surface, and dry conditions result in the lack of sufficient moisture to start and sustain the germination process.

Objective:

The students will be able to describe how some environmental factors affect seed germination.

Materials:

Masking tape, Scissors, 3 ziplock bags, Marker, Forceps, Paper Towels, Metric Ruler, 3 colored pencils, 25 seeds, distilled water, 50 ml graduated, 1% detergent solution, 10% detergent solution, graph paper

Procedure:

  1. Label the 3 zip lock bags: Control, 1% Solution and, 10% Solution.
  2. Cut 6 square pieces of paper toweling to fit each bag.
  3. Place 2 squares in each bag.
  4. Distribute 6 seeds on each side of the paper towel between the plastic and towel.
  5. In the control bag add 25 ml of distilled water completely moistening the paper towel.
  6. In the 1% solution bag add 25 ml of 1% detergent solution making sure to completely moisten the towel.
  7. Do the same to the 10% solution bag by adding 25 ml of 10% detergent solution.
  8. Make sure all bags are sealed tightly.
  9. Place the bags in a dark warm place designated by the instructor.
  10. Write a hypothesis predicting the results of the experiment.
  11. Examine the bags daily for 5 days. Record any changes that might have occurred. If the roots is visible the seed is considered germinated.
  12. Record your date in the table below.
  13. Do not allow your towels to dry out. Moisten each bag with the appropriate solutions in equal amounts.
  14. Measure the root growth of each seed daily from the time it appeared.
  15. Graph the data from the table using the colored pencils to represent each of the zip lock bags.
