Has your house ever suffered an ant invasion? This project is an interesting way to investigate what substances are effective as ant repellents. The goal is to find substances that keep ants away, yet are safe for humans and the...

This NSTA vetted source includes resources to teach ideas on reducing the impact of humans on the environment. Included are assessment ideas, videos, examples, lesson plans, and photos of student work.

Describes the ecology of the Amazon rainforest, the characteristics of its climate, the impact of human actions on this environment and the need for stronger conservation efforts to save the rainforests.

Humans need food, water, and warm shelter to survive. But a lot of humans depend on fossil fuels to supply gas and electricity to heat our homes. But burning fossil fuels to create energy is harmful to the environment. In this science...

In this science fair project you will learn about biomes and how different climatic conditions affect plant growth. This can explain why some plants and animals are similar in different areas of the country, and in other parts they are not.

This NSTA vetted source includes resources to teach about the relationship between the needs of different plants and animals and the places they live. Included are assessment ideas, videos, examples, lesson plans, and photos of student...

Like humans, plants can be negatively affected by overcrowding. Unlike humans, plants cannot get up and move to a new environment or explore how to utilize new resources. This experiment will explore the effects of crowding (population...

This is an interesting experiment for an Investigator who is 1) curious about insect metamorphosis and 2) patient. You'll need to set up different controlled environments for the chrysalides, and then check on them regularly as you wait...

Taking advantage of free energy can reduce our dependence on fossil fuels, which are harmful to our environment. In this science fair project, you will work with a solar panel, which is a collector of free energy, and investigate how...

Sometimes bats can "whoosh" right by you, and not be seen. In this science fair project, you will be able to detect flying bats by listening in on the ultrasonic signals they produce to locate objects in their environment. The bat...

You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of...

[Free Registration/Login may be required to access all resource tools.] For a population to be healthy, factors such as food, nutrients, water and space, must be available. Limiting factors are resources or other factors in the...

Begins with a description of a case of missing plant nutrients that have been affecting Monongahela National Forest in West Virginia. Lists some of the benefits to humans of the natural resources in such a park. Then explains the...

In this lesson, the students will learn what a terrarium is, the layers of a terrarium, and the function of these layers. They will see how these components work together to create an ecosystem. This lesson plan was created as a result...

Work samples, phenomena, assessment templates, and videos that directly address standard 3-LS4-1: fossil evidence of past environments.

Third graders will observe changes in a small environment.

Develop a more nuanced understanding of how student ideas are formed both in and outside of the classroom. By understanding the student's misconceptions on scientific ideas, you can better structure your lesson to be more effective. This...

Find out why coal causes pollution and several techniques that can be used to clean it up.

Kids learn about wind energy and how this renewable power can help the environment. Teach students about turbines that generate electricity from the wind.

Kids learn about renewable energy and how it can help the environment. Teach students about solar, wind, biomass, and geothermal energy.

Kids learn about wave and tidal energy and how this renewable power can help the environment. Teach students about this new technology.

Kids learn about solar energy and how this renewable power can help the environment. Teach students about solar cells and using the sun for heat.

Review ecology, the study of how living organisms interact with each other and their surrounding environment.

This comprehensive study guide covers the main terms and concepts needed for an earth science unit on coastal pollution. Review questions are included at the bottom of the study guide.
