Students define extinction, name four animals and two plant species that are extinct, list three reasons why animals and plants become extinct, and create ways that would help prevent extinction.

Learners identify invasive species to the Great Lakes and analyze their impact on the ecosystem. Using photo cards with pictures and facts, young scientists work in small groups to match invasive species with their corresponding...

Wetlands may not sound particularly ornate, but they are as important as any habitat! With a hands-on activity, young scientists build a wetland model and observe its many functions in action. They discover the importance of wetlands to...

Students examine the pH level of rain water in their local community. They locate each location on a map. They analyze the data and draw conclusions.

Learners identify solid waste and water pollution concerns. They discuss how to prevent water and air pollution as well. They describe any behaviors they have that would be considered environmentally irresponsible.

Students identify many different ways the environment is polluted, and determine ways to prevent pollution. They create a collage of pictures describing how the earth becomes polluted.

Students identify pollution around their local community. They discuss the sources of polution and categorize objects based on their properties. They discover ways to make changes to the environment and how to inform the public.

Fourth graders explore the concepts of conservation using a reading story that describes a flock of geese. The ecosystems are also described in the lesson and the effects of pollution.

Youngsters develop an understanding of how smog is produced, and how exhaust from automobiles is one of the major sources of smog. They explore the roles that engineers play in developing technologies that reduce smog, then work in teams...

To better understand how solar power can aid in creating desalinated drinking water, the class creates a model still. They will build a model of a solar still, make observations, and discuss how the process works. While the idea behind...

Coral reefs are full of an abundance of life and color. Why not celebrate it with an edible coral reef? Learners and teachers alike use cake, icing, and candies to create a tasty version of a coral reef that's complete with colors,...

Students work together to build a trash city. They collect items that would go into a landfill to help them build their city. They discuss ways to cut down on garbage.

Learners find ways to decrease soil runoff for an African Village as a part of a Peace Corps project. For this soil runoff lesson, students play a soil runoff challenge online. Learners complete online activities and view a slide show to...

Students grow crystals and document their observations by recording timeing and growth. Additional characteristics of crystals are observed under a black light, by growing under different conditions and mineral content is determined.

Students participate in an environmental action letter-writing campaign. They conduct Internet research on the Global Response website, discuss various successful Global Response campaigns, select a campaign they are interested in, and...

Students explore the concept of air pressure. Using candy or cookie wafers to model how air pressure changes with altitude, they conduct an aluminum can crushing experiment, compare the magnitude to gravitational force per unit area,...

Students explore how storm water flows through different habitats by sketching the slope of their yard, compare runoff for erosion, and create a sand castle. In this storm water lesson plan, students measure where their yard started...
