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.)
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!)
