Food web assignment grade 9

Create food web from food chains (20 minutes) Have students practice making their own food webs with the species in their food chains. On a large piece of paper, students set out their cards in a random arrangement. Now, using the food chains students created previously, place arrows among the organisms.

Making food webs with more than 8-10 species can be quite challenging, so try building food chains and webs with cards yourself first before using with students. You may want to give each group the same 8 species, or use different sets. Directions Engage students with “rock-paper-scissors” activity that models a food chain (10 minutes)

Modeling Food Web Interactions (15 minutes) Write the name of each organism from the food web on an index card, or use species cards. Ask students to form a circle and assign one organism to each student by taping the organism index card or species card to his or her shirt.

The food chain looks like this: Food chains are a simple look at how sunlight is made into energy by plants through photosynthesis, then how that energy is transferred from animal to animal after eating the plants. Food webs look at how multiple food chains interact with each other.
