1 Energy in Animals Classwork 5 th Grade PSI 1) Define Energy. Give an example. 2) Why do animals need to eat? 3) Complete the following chart to show what Energy is used for in animals: Use of Energy Description (slides ) Body Repair Growth Warmth Motion 4) Describe cellular respiration in your own words. What does it do and why is it important? 5) What is the equation for cellular respiration?

2 Energy in Animals Homework 5 th Grade PSI 6) Where do we get our energy from? 7) What type of energy is found in food? 8) Name and describe 4 ways animals use energy. a. b. c. d. 9) In your opinion, what is the most important use of energy by living things? 10) Complete the equation for cellular respiration: Food + = + Carbon Dioxide +

3 Energy in Plants Classwork 5th Grade PSI 11) Where does the energy plants need come from? 12) Describe the process of photosynthesis 13) What are the 3 materials required for photosynthesis? 14) Describe what the products of photosynthesis are. 15) Write an equation showing photosynthesis 16) Define chloroplasts. 17) What are the two main stages of photosynthesis?

4 Energy in Plants Homework 5th Grade PSI 18) Draw a picture showing the transfer of energy from the sun to animals. Label each step. 19) What are the materials used to begin photosynthesis? 20) What are the products of photosynthesis? 21) Why do leaves change color in the fall?

5 Energy Flow Classwork 5th Grade PSI 22) How are photosynthesis and cellular respiration similar? 23) Can photosynthesis and cellular respiration exist without one another? 24) Copy the finished drawing of the cycle on slide 49.

6 Energy Flow Homework 5th Grade PSI 25) Why is the cycle of Cellular Respiration and Photosynthesis important to life for plants and animals? 26) How are the products of Cellular Respiration used in the process of photosynthesis? 27) Draw your own cycle of Cellular Respiration and Photosynthesis. Use one plant and one animal of your choice. Make sure to label all of the materials that are produced or released. Also, make sure to use arrows to show the flow of material.

7 Energy in Organisms Classwork & Homework Answer Key 1) Energy is the ability to do work. Examples will vary. 2) Animals needs to eat to support their live. The energy gathered from food supports all their functions. 3) Body Repair fixing the body Growth - creating new cells Warmth creating or maintain internal temperature Motion providing movement 4) Cellular Respiration is the process in our body that releases the energy stored in food for our use. It allows animals to access the energy that the plants have created. 5) Food + Oxygen = Energy + Carbon Dioxide + Water 6) We get our energy from eating plants or other animals that eat plants. 7) Chemical Energy 8) Body repair, growth, movement & warmth 9) Answers will vary, students should justify their response 10) Food + Oxygen = Energy + Carbon Dioxide + Water 11) The energy in plants comes from the sun. The materials for growth come from the soil and air. 12) Photosynthesis it the process through which plants collect sunlight and turn it into food. 13) Sunlight, carbon dioxide and water 14) Sugar (energy) and oxygen 15) Carbon Dioxide + Water = Sugar + Oxygen 16) Chloroplasts are specialized structures in plants that use a chemical called chlorophyll to collect light. 17) The two steps are the collection of sunlight and the storage of the energy as sugars. 18) Pictures should include plants using photosynthesis, converting the sun into energy and animals consuming the plant. 19) Carbon dioxide and water 20) Oxygen and water 21) In the fall there is not enough sunlight is collected and the chlorophyll stops working (being green). The plant must use other chemicals, which are different colors like red, brown, and orange. 22) They are both cycles. 23) No, they are dependent upon each other. 24) Students should complete the drawing found on slide ) They allow for life to exist and are mutually beneficial. Without each other the functions would not exist.

8 26) The products of cellular respiration, water and carbon dioxide are used by plants to fuel the process of photosynthesis. 27) Drawings should be similar to the figure on slide 49.
