Students sort items into food and non-food categories, then play a game to get enough food - nutrients and energy - to support six ecosystem organisms.


Students will be able to:
- understand that all living things need nutrients and energy
- know that food is a substance that porvides both nutrients and energy
- realize that nutrients alone don't contain useable energy
- realize that their bodies are made of the same substances that food is made of because food becomes part of the body - you are what you eat!
- know that nutrients cycle in an ecosystem, whereas energy eventually is lost as heat
- know that plants get energy form sunlight and nutrients from soil, and animals get them both from their food
