8. Let’s Create a Food Chain!
•Use the organism cards provided to create two
SIMPLE food chains.
•Make sure the ARROWS point to
Who GETS the ENERGY!!
•When you are done, wait quietly for the timer to
go off so we can share your ideas! (up to 5 min.)
9. Let’s Create a Food Web!
•Now try combining more organisms to make a FOOD
WEB.
•Make sure ARROWS point to Who GETS the ENERGY!!
•* You may use your eraser to draw arrows on your lab
table connecting the organisms!
•When you are done, raise your hand to get it approved.
•Draw the web onto a sheet of notebook paper using
WORDS & ARROWS only! (No pictures required!)
