Food Chain ActivityDemo

Find a Partner

Use organism ID cards to construct a food chain I will walk around and see if they're in the right order

Pay attention to organisms diet/ food preference to organize it into appropriate trophic level

Fill out Claim/Evidence chart with your partner

Be prepared to share results!
