Weave a Food Web

Here is a practical activity for reinforcing understanding of energy flow in ecosystems. Learners identify whether each organism in a list is a producer or decomposer. They tell if each is an herbivore, carnivore, omnivore, or...

Learners of many ages discuss how all organisms rely on other organisms for their survival. They construct a food web and energy pyramids, and write an informative essay about the food web that they have designed.

Learners explore organisms that are part of interconnected food webs.  In this food web lesson, students choose an animal and research what the animal eats.  Learners begin with the food chain and branch out into the interconnected web...

It is always fun to weave a web when studying the relationships in ecosystems! Thirty organism name cards are provided. Divide the class into groups of eight, then give each participant a card and the group a few long strands of yarn....

Young scientists weave together an understanding of ecosystems with this fun collaborative activity. Taking on the roles of different living and non-living elements of specific habitats, learners use a ball of yarn to create the web of...

The class will make observations to determine how environment has shaped the way particular birds and fish eat. They will view a series of photographs, read two short articles, and then consider how food availability has determined how...

Students research and create a marine food web to learn about plants and animals in a kelp forest. For this marine food web lesson, students draw lines between kelp forest predators and prey and show the flow of energy in the food web....

While this instructional activity focuses on the birds and fish found on the Hudson River, it could be adapted for use in any classroom. Using a vocabulary list, learners explore the meaning of words like adaptation, habitat, barbel, and...

Students demonstrate the interrelationships of animals and plants. For this ecology lesson, students discuss the things plants and animals need for survival and study the glacier food chain. Students simulate the web of life by using a...

Fifth graders investigate the food chain by viewing video clips. In this food web lesson, 5th graders investigate populations and ecosystems by viewing a video in class as well as visiting web sites. Students utilize the Internet to...
