Students consider why we eat and where our food obtains its energy. They illustrate food chains that might be found on an open field, dissect owl pellets, identify the remains of animals in the pellets, watch videos and participate in...

Students identify the relationship between predator and prey in the food chain. In this food chain lesson, students work in groups and play a predator and prey game. Students discover what happens when a predator does not find prey. 

Students explore the ecosystem by reviewing scientific vocabulary terms. In this environmental awareness lesson, students identify the differences between abiotic and biotic factors and their relationship to the Earth. Students define...

In this energy flow worksheet, students will complete 10 short answer questions based on a food web diagram. Then students will review different cycles in nature including the water cycle, carbon cycle, and energy cycle. This worksheet...

Fifth graders examine the concept of the food chain and define producer, consumer, herbivore, carnivore, and omnivore. They draw a food chain for a mouse and discuss the different organisms involved in the chain, and conduct an...

In this food web study worksheet, learners record how 24 animals get their food. Each animal should categorized as a forager, grazer, filter feeder, parasite, predator, or scavenger on the graphic organizer.

Students explore what a food web is. In this science lesson, students examine how nutrients and other pollutants enter a lake and play a food web game whereby students pretend they are either zooplankton, planktivore,...

Students become familiar with food chains.  In this food chains lesson, students understand that as consumers eat other consumers energy is passed. Students understand the vocabulary associated with food chains.

Students investigate the dietary habits of living organisms by creating a model food chain.  In this food web instructional activity, students define several food chain vocabulary words such as omnivore, carnivore and herbivore....

The Arctic food web may be more limited than other environments, but it has all the same components. With an interactive activity, pupils assume the roles of the components of an Arctic food chain. They move around and link themselves to...

Young scholars investigate the decomposition process. In this ecology lesson, students participate in a play, "Up the Treehouse" where the main idea focuses on a decomposing tree and how food chains are effected by decomposition. After...

Students describe the importance of having a balance ecosystem. After a brief lecture, students give an explanation of the properties of an ecosystem. They create a web, using yarn which shows how the various members of the ecosystem are...

Students study the benefits of estuaries. They construct a saltwater food web, and complete worksheets and a quiz.

Get your hands dirty with an interactive lesson that showcases the process of decomposing and returning nutrients back into the soil. After building a compost pile, pupils regularly observe the...

From tiny organisms to entire biomes, young scientists examine the interdependent relationships tying all living and non-living things together with this collection of ecology resources.

What better way to learn about ecosystems than by getting outside and observing them first hand? Accompanying a field trip to a local park or outdoor space, this series of collaborative activities engages children in...

Students will be able to find out about feeding relationships on a coral reef. They then will be able to develop a food chain and food web using coral reef animals and plants using the Coral Website.

In this science activity, students match the words given in the first column with the correct definition found in the second column. There are six vocabulary terms to define.

Students identify why humans are dependent on natural resources and the problems associated with their use and demonstrate how humans affect their environment. They also describe the different components and natural resources that go...

Students explore the ecosystem and food chain by researching Pacific Salmon. In this fish habitat lesson, students discover the life cycle for salmon, where they spawn and what they eat to survive the harsh elements. Students participate...

Students watch an episode of "Nature" about the "Big Red Roos." They create food chains and webs based on the information they've researched on the red kangaroos. They write an editorial on the topic of the killing of kangaroos in the...

Students explore animal and plant adaptation.  In this ecosystems science lesson, students view websites to gain information about plankton and its  interdependence within ecosystems. Students identify ways in which plankton...

Three types of symbiosis are explained: parasitism, commensalism, and mutualism. This is done with colorful animation and lively dialogue in a straightforward and easy-to-follow manner. Have your ecology class watch this at home and then...

The story of one bird provides valuable insight into general animal behaviors and interactions. Young researchers investigate the peregrine falcon using a web search. They analyze the behaviors of the raptor including its migration...
