Food Chains and Food Webs
6th - 9th
For this biology worksheet, students read about food chains and food webs. They then answer 4 questions regarding the information they just learned. The answers are on the last page in the packet.
Constructing Schoolyard Ecosystems and Food Webs
Pupils explore food webs by participating in a scavenger hunt activity. In this plant identification lesson, students discuss the types of plants and food that grow on their campus and the animals that eat them. Pupils create a food web based on the food in their school and later complete a food scavenger hunt around their campus.
Learners discuss the ways that animals are dependent on plants or other animals for their food. They create a class-sized food web to show how energy is transferred. Each student wears a plant or animal picture and suggests ways to connect into the web by using yarn to show all of the connections.
Learners take a look at the relationship between organisms in food chains, food webs, and energy pyramids. After an opening demonstration by the teacher, pupils are split up into groups. Each one is assigned an environment such as: ocean, pond, forest, and desert. They construct an energy pyramid for their environment and present it to the class. A very nice example of good group work where everyone gets to learn from each other.
Plankton to Penguins: Antarctic Food Web
A well-written lesson plan, second in a series of four, gets high schoolers exploring how the Antarctic food web is impacted by climate change and the associated melting of polar ice sheets. It begins with a PowerPoint presentation about the polar ecosystem. Small groups use beads and game cards to model how decreasing sea ice impacts the food web. To close, a class discussion ensues about ocean acidification and what pupils learned from the activity. Be sure to consider using the entire unit in your environmental studies course.
Impact of a Changing Climate on the Pacific Walrus
How many of us can say they've seen a Pacific walrus? Not many and one of the reasons is the impact of climate change on their aquatic environment. Children get to think about the food web of the Bering Sea by creating an actual web with animal cards and a ball of yarn, after they see how all animals and plants of the sea environment are connected, they discuss what would happen if one or more of the animals were to become extinct. The web would start to break down and all animals would be affected. They research ways to protect a declining walrus population.
Interactive Food Webs
Introduce the concept of food webs and chain reactions. Students explore a series of provided web sites and work collaboratively to complete an activity and worksheet. This is a supplemental activity to reinforce a larger lesson.
Food Webs in a Pond
Students explore food chains and food webs in a pond and identify common creatures found in ponds. They look for tadpoles, fish, mites and other creatures in a pond during a field trip for first hand research.
The Food Web
Students explore the role that the Arctic hare plays in the Canadian Arctic food web.
Forest Food Web
Fifth graders examine the forest ecosystem. In this ecosystem activity, 5th graders identify animals and plants living in the environment and construct a diagram. Students discuss the impact on the food web if select animals and/or plants are removed.
Food Chains and Food Webs
Students discuss the characteristics of producers, consumers and decomposers. Using a flow chart, they construct a food chain to visually show how organisms with different energy sources depend upon one another. Students explore a model of a food web and discuss characteristics of each consumer.
