You have already learnt a lot about food chains, including the concepts of energy flow and different roles of organisms in a food chain, and so on. Nonetheless, there is still a crucial concept related to food chains that needs to be addressed. This concept is the key to explain how food chains can maintain stability.
It includes objectives, materials, procedures, and activities like a video, game, and group work to help pupils understand producers, primary consumers, secondary consumers, tertiary consumers, apex predators, and decomposers in food chains and the transfer of energy between each level.
Like a spiders web, if one part is removed, it can affect the whole web. FOOD WEBS show how plants and animals are connected in many ways to help them all survive. FOOD CHAINS follow just one path of energy as animals find food. Get science experiments and science fair ideas at www.sciencebob.com.
• Create a model (e.g., a food chain) showing feeding relationships among organisms. • Evaluate different models that depict relationships among organisms in a community. • Predict how ecological forces or disturbances may impact their models and justify their claim
The students will read about what is a food chain and the levels in a food chain, create a food chain showing levels of consumers, and play a food chain card game with pictures of consumers and producers.
Food chains and food webs are important science concepts that help children understand how living things in nature are connected. It also shows how living things rely on each other for food and energy ("Food chain background," 2014). Rationale. Why Should We Teach Science in Elementary Schools?
Activity: Exploring Food Chains and Webs. Key Question. How is energy transferred among organisms in ecosystems? What is the relationship between food chains and food webs? Objectives. Students will. describe how energy flows through food chains and food webs. build and examine food chains and food webs.
