Learners 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 the...

Fifth graders explore how invasive species affect the Great Lakes. In this science lesson, 5th graders research invasive species and create a food chain involving the invasive species. Students discuss how the environment is affected by...

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...

Pupils 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...

Krill is a very small ocean animal that is key to keeping the ocean ecosystem going. The class reviews food webs and chains, learns about the importance of krill, discusses krill anatomy, builds a model of a krill, and then has a...

Students interpret data to demonstrate biomass and number pyramids. They use information to draw conclusions and examine an example of biological magnification.

Students identify a food chain sequence. They compare, identify, and record the rodent skeletal parts to a rodent skeletal diagram. Students construct a rodent skeleton from the skeletal parts found in the pellet. They are given the...

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 explore the concept of biomass. In this plant lesson, students conduct a scientific investigation that requires them to observe plant growth and biomass.

Young scholars research bird migration and build a bird house. In this bird lesson plan, students research the birds in their area and where they migrate to. They also build their own bird house and record data on what kinds of birds...

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 lesson....

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 gain an understanding that the Sun is the source of all energy. With a partner, they examine various web sites to explore food chains and food webs, later sharing their findings with the class.

A blood sucking what? Grade schoolers identify the characteristics of blood sucking parasites. They organize their information, identify their arguments, and present them to the class in persuasive arguments. They participate in a debate...

Here is a well-designed science lesson that shows learners that everything that organisms do in ecosystems, including running, breathing, burrowing, growing, requires energy. After a thorough discussion of their own eating and drinking...

Learners identify various animals and their habitats, as well as their specific traits In this animal habitat lesson, students list animals they've seen in their backyard. Learners select one animal and do research. Students then answer...

Have your class learn about marine life through this resource. This comprehensive lesson has learners discuss marine life, learn key vocabulary, discuss environmental concerns, and play games related to migration and predator/prey...

Students explore seed dispersal by designing their own wind dispersed seed structure. Using one piece of paper and a box fan, they construct a seed dispersal structure, record the distance their seed travels, and answer discussion...

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

In this unit of lessons, young scholars examine solid waste and recycling. They discover the concept of decomposition. They also observe the decomposition process and make observatins.

Students look at the data maps given to them about how chlorophyll affects the algae blooms and make predictions about the harm they will cause. In this data maps lesson plan, students manipulate data sets from the website.

Students use various web sites to access information about the rain forest. They use the Tropical Rainforest Interactive CD to make their own rain forest pictures and stories and learn facts about the rain forest. They use various books...

Young scholars understand what physical adaptations are and how they help an animal to survive. In this adaptations instructional activity, students research four animals and then make an original animal that has adaptations to make them...
