Young scientists discover how sea otters' habitats have changed due to human impact. Through conversation, video observation, and story reading, scholars identify how human interactions change a specific ecosystem in both positive and...

Students familiarize themselves with the common organisms that live in a pond and discover their importance in a balanced aquatic habitat as they create food webs. They also investigate how an environmental change affects the habitat as...

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...

Students complete a unit of lessons on ecosystems. They participate in online activities, create a diorama, write journal entries, and develop a Hyperstudio multimedia project on a selected ecosystem.

How is energy transferred within an ecosystem? What would happen to a food web if one of the organisms was removed? Elementary or middle school ecologists examine these questions and more in a comprehensive 5E learning cycle...

Students perform an activity in which they discover what happens when food chains overlap in an ecosystem and discover the three components of a food web.

Students identify the organisms found near their school or house and observe them.  In this food chain lesson students examine how an organism gets their energy and then fill in a chart to create a food web with the organisms they...

Students identify plants and animals in the journals of Lewis and Clark's expedition. They describe the various animal habits. Students interpret the behaviors of the animals discovered on the expedition. They design a food web using...

Students use the EcoKids web site to explore food chains and the associated terminology. They answer the questions about food chains and their importance. Students use the Kidspiration program to add information to an Animal Fact Web.

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

A branching key is a great way to classify different types of animals and plants! Fifth graders answer several yes/no answers about three different plants. They then create their own key to differentiate between an iris, a rose, and a...

Producers, consumers, food chains, and plants are the stars of this science lesson. Learners take part in an inquiry which helps them to discover the most effective and efficient way to grow a producer. They have a variety of containers...

A lab activity is a great way to incite thoughtful questioning and scientific processes. Pupils will collect organisms with a Petri dish, make observations, sketch the organism, ask questions, then attempt to identify the specimen...

Pupils identify the role predators/prey play in food chains, differentiate between food chains and webs, identify factors that affect the balance in food webs, and propose solutions to protect endangered species' environments and insure...

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. 

Pupils 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. Pupils define terms...

Learners 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....

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, students 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,...

Off the coast of California lives a wild animal called the Island Fox. Experts discuss the importance of the Island Fox to the Channel Islands and the balance the fox creates within its ecosystem. The lesson concludes with a reading of...
