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
