What kids do
Printed on the sheet:
- A food chain shows who eats what. It starts with a producer, a plant that makes food from sunlight.
- The arrow points to the animal that eats it.
- Meadow: snake, grass, frog, grasshopper
- Forest: hawk, acorns, snake, mouse
- Ocean: seal, krill, algae, penguin
- Where does the energy in every food chain first come from?
Teacher tip
Remind kids that every chain starts with a plant and the sun.
How to use it
- Use a ball of yarn to build a food web in a circle of kids.
- Start every food chain with the sun so kids see where energy comes from.
- Let partners compare answers and settle any differences with a book or a video.
Watch for
Arrows in a food chain point to the eater: they show where the energy goes.
Talk about it
- Why are decomposers important?
- What did you notice that surprised you?
