In this environmental science fair project, students will learn some of the ways in which the population growth of animals is modeled, and then use the logistic model to determine how a population grows when it starts far below, at, or...

Have you ever heard the expression "a canary in a coal mine"? In the 1900s and earlier, coal miners brought canaries with them into the mines to act as early warning signals. The canaries were very sensitive to low levels of dangerous...

In this environmental science fair project, students will build models of fields prepared by plow-based and no-till methods, and see which ones are best at retaining soil moisture and preventing surface runoff.

This elegant project employs a scientific approach that is particularly valuable in Environmental Science, but can be applied to other areas as well. The approach has three steps: 1) from your observations in the field, form a...

Explore the General Introduction to Environmental Geology, Environmental Ethics, The Environmental Crisis, and Fundamental Concepts of the Environmental Sciences in this class resource. Lesson plans and activities are offered to help...

If you care about the environment and are interested in a career which protects it, you might want to investigate the career of environmental compliance inspector. These inspectors are employed by governmental agencies as well as large...

There are so many kinds of engineers. The environmental engineer has the opportunity to have an impact on the quality of life of thousands, if not millions, of people because of the solutions to environmental problems they develop. This...

Read about the environmental engineering technicians who do the hands-on work that is developed by the environmental engineer. Science Buddies offers a career profile which outlines the educational requirements and lays out the nature of...

The element lead is a neurotoxin that is particularly dangerous to young children. Among other uses, lead compounds were common paint additives until being phased out for safer titanium-based additives beginning in the 1960's. Lead...

What covers less than 10% of the Earth's surface, yet is a vital natural resource for terrestrial life? What filters ground water and supports most of our food production, not to mention the production of building materials and paper?...

Did you know that soils can be alkaline, neutral, or acidic? Most plants grow best in soil near neutral pH, but some plants prefer slightly acidic and others slightly alkaline soil. What is the pH of the soil in your garden? What happens...

Chemicals from the Earth's atmosphere are making their way down to the planet. Not in spaceships, but in rain. The acid rain can infiltrate ground water, lakes, and streams. How does acid rain affect aquatic ecosystems?

Did you know that when you use fertilizer in your garden, it can eventually reach a lake, stream, or pond? There are many different chemicals present in fertilizers. Learn how they affect the aquatic organisms in the ecosystem within...

You might know that lead can be toxic, and that you can get lead poisoning from eating or inhaling old paint dust. Lead is called a heavy metal, and there are other sources of heavy metals that can be toxic, too. Silver, copper, mercury,...

Ozone in the stratosphere protects the earth by absorbing harmful ultraviolet radiation from the sun. However, when ozone occurs in the troposphere, it is harmful to health. In this project you can use data from EPA monitoring stations...

Water is a valuable resource many often take for granted. This exercise however gives you the opportunity to learn about and discover how greywater (water that has been used for washing or bathing) can be used for watering ornamental...

In this environment-oriented experiment, you will mix it up with earthworms, soil, and various types of organic kitchen scraps. The basic idea is to set up small earthworm colonies to compost different types of food waste. You test the...

In a bioassay, a living organism serves as a detector for toxins-the same way canaries were used in coal mines to detect invisible toxic gases. In this project, water fleas (Daphnia magna), a freshwater crustacean, are used in a bioassay...

Algae is a good thing, but too much is a bad thing. In this environmental science fair project, grow algae in several concentrations of fertilizer and observe its effect on algal growth.

In this science fair project, test the toxicity of "green" and conventional detergents, using worms as test organisms. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

Watch out. It's Eddy Vortex, Superhero. He swirls, he tumbles, he churns up air and water. OK, maybe eddies and vortices aren't exactly superheroes, but they are powerful regions of air and water flow that you have to watch out for in...

Use this science fair project to learn how to test your soil to see if it is getting the right amount of water from the sprinklers. Project is set up beginning with an abstract, objective, and introduction, followed by a section on...

In this science fair project you'll discover how to turn the ocean into a source of freshwater by using the power of the Sun, and the water cycle. You will ultimately find just how salinity affects this process.

In this science fair project, you will learn more about wind-powered devices, like pinwheels. Much like pinwheels, we react in different ways to the direction of the wind when we ride bikes, or even try to walk.
