Activity 2-1: Draw a Food Chain

PLAN

Summary Students learn about relationships in a food chain by drawing two different food chains. One food chain is based on what they ate for breakfast. The other food chain is based on the food of a bird of prey.

Objectives

Students:

\checkmark trace a food chain based on an item from their breakfast.

\checkmark explain the relationships between the organisms in a food chain.

\checkmark explain that almost all energy used by plants and animals originates with the sun.

Student Materials

Per student

  • Activity Report
  • Paper

Per class

  • 6 sets of marking pens, pencils, or crayons

Teacher Materials

  • Activity Report Answer Key

Advance Preparation

Prepare copies of Activity Report.

Estimated Time

20 minutes, depending on discussion time

Interdisciplinary Connections

Visual/Performing Arts In Activity 2-1 students will draw food chains. The students can build a mobile from the food chains they draw.

Language Arts Students write a story describing the relationships in their mobile. They write about how each organism depends on the others.

Prerequisites and Background Information

None

IMPLEMENT

Introduce Activity 2-1 by reviewing the concept of a food chain and emphasize that all our energy can be traced back to the sun.

Steps 1-4 Have students follow the instructions for Activity 2-1 in the text. Supply them with paper and colored pens or pencils. During the activity remind students to use a food derived from an animal that they ate for breakfast. This will allow for a longer food chain.

Step 5 After students have completed their food chains, you may want to hang them up around the room and compare breakfasts.

Extend Activity 2-1 by having students join their food chains together to make a food web. This will provide a transition into the concept of an interdependent food web rather than a linear food chain.

Students can choose one of the two food chains they've drawn and make it into a mobile. They can use pictures of animals and plants, construction paper, and their own drawings to make the parts of the mobile. Next, they can connect these parts with yarn according to the lines on their sketch. Each animal and plant should be connected only to the organisms that eat it or that it eats. Finally, you can hang the mobiles around your classroom.

Have students write a story describing the relationships displayed in their mobile. Encourage them to write about how each organism depends on the others.

ASSESS

Use the final product, a drawing of a food chain, to assess if students can

\checkmark explain that the energy for the food chain originates with the sun.

\checkmark draw and explain the correct arrangement of the organisms in the food chain.
