In this biology learning exercise, students answer 22 multiple choice questions on ecosystem. They identify which ecosystem component is described in each of the question.

Students create a bulletin board display illustrating food chains they make from a list of ocean organisms. Students also play a game showing what happens when one of the organisms is removed from the food chain and how they are all...

Learners, in groups, create a slide show about the ecosystem and answer critical thinking questions based on their research.

Students study dinosaur teeth and bones to determine the creatures diet, size and shape.

Learners research rainforest animals and use that information to make a flow chart to show the order in which energy is transferred through several organisms. They label the producers, consumers, and decomposers in their chart.

Students study the balance necessary to maintain ecosystems and how changing that balance can impact the ecosystem. They identify and discuss the need for balance in any ecosystem and discuss how greenhouse gases impact ecosystems.

Students study food chains and how the organisms are linked.  In this investigative worksheet students answer food chain questions, and fill out several worksheets.

Learners examine how food webs illustrate the ways in which organisms depend on each other for energy and nutrients, and make food webs showing the feeding relationships among organisms encountered in the Gal??pagos coastal waters.

Students use a large seet of habitat cards, spread out in one area. They, in groups, practice sorting themselves into the correct habitat based on what function card they received.

Second graders examine how food chains interact with different plants and animals. They practice using new vocabulary. They also discover the role of pesticides in the environment.

Sixth graders define terms prey, predator, and scavenger, describe predator-prey relationship, discuss effects of a lack of predators in an environment, and separate the role of the scavenger from that of the predator.

Seventh graders create a model of an ecosystem and label it to show structure and function. They research the food web of an aquatic animal and also trace energy flow from the primary producer up the food chain.

Students discuss millipedes and centipedes in terms of their classification as arthropod. Using a diagram, students categorize and compare and contrast the characteristics of millipedes and centipedes based on their discussion of...

Students study the concepts of seed dispersal, germination rate, exponential population growth, and predation by engaging in a bean 'weeds vs. natives' relay race. They illustrate how weeds out-compete other plants for space by crowding...

Students investigate how all links in the food chain are related. In this animal habitat lesson, students hypothesize about what would happen in the food chain if an endangered species were to become extinct. This lesson also includes an...

Students investigate the food chain. In this ecology lesson, students define producers and consumers. Students use organism cards to demonstrate how the food chain works.

In this bats worksheet, students click on the links in the questions about bats to find the answers to the questions and then come back and answer the questions. Students answer 19 questions total.

Young scholars examine the different plants and animals in British Columbia.  For this forest ecology lesson students explore how ecosystems work, classify animals and investigate food webs and chains. 

Students explore dinosaurs. In this science lesson, students discuss the characteristics of various dinosaurs and color masks and pictures of the dinosaur groups they have chosen.

This PowerPoint features a game based on the animal life. The interactive slides include 20 questions about animal needs, animal groups, and animal traits. The questions include multiple choice answers and 4 different levels of...

In this mammals activity, students use clues given to complete a crossword puzzle of words associated with mammals. An answer key is included.

Students determine the sequential links in a marine food chain and identify the roles that various organisms play in this chain. Students develop charts as visual aids for illustrating marine food chains.

Learners identify and explain the relationships within a food web. They use index cards to glue pictures of producers and consumers. On the back of the card, students name the organism, list the type of biome in which it is found.

Students discuss the food chain and identify if various organisms are producers or consumers. They draw ten types of organisms and construct a food web of these organisms, labelling each as a producer or consumer.
