Energy in Food Write Up
Introduction:
Use your lab and your textbook to locate and include the following information in your introduction.
- What organisms are capable of making their own food?
- What process do they use to do this?
- Where do these organisms get their energy for food-making?
- This energy is captured with the help of what pigment?
- This energy is stored in what organic molecules?
- Where exactly in the organic molecules is the energy stored and so it can be used again later? (Hint: Energized electrons form these and then energy is released again when they are broken.)
- What process takes place in plants & animals to release energy?
- What gas is required for the process to occur?
- When foods are “burned” in our bodies, where is the energy being released from? Where did this energy originally come from?
- What is the usable form of energy for our cells?
- Define calorimetry and explain how it can be used to measure energy stored in chemical bonds of food.
Hypothesis:
- Write a statement explaining that calorimetry can be used to detect the amount of energy stored in the chemical bonds of foods.
Materials:
In sentence form, write a statement listing the materials required for this lab.
Procedure:
- In paragraph form, write the procedures for completing this lab.
Results:
- Draw and fill in table 1 showing the results of burning
- Draw and fill in table 2 showing your data analysis for nut calorimetry
- Write out and answer the questions on the lab. Remember to write and underline the question, but do NOT underline the answer.
Conclusion: (Write in paragraph form.)
- Restate your hypothesis.
- Tell how were you able to measure the amount of energy in each nut
- Did all three nuts contain the same amount of food energy? Explain by giving data from your experiment..
- Explain why some foods contained more energy than others
- Tell where this energy originally come from and how it got into the nuts
- Explain any errors you might have made in lab that could have affected your results
