In this science fair project, use Google Earth to determine if large mammals align themselves in respect to the earth's magnetic field. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and...

In this project, you will estimate the circumference of the earth, using a method developed about 2,200 years ago, by Eratosthenes, a Greek mathematician and the librarian of the great library at Alexandria, in Egypt.

Want to stretch your imagination? One good way is to try to imagine how far it is to a distant star. How much farther away is it than the moon is from the earth? In this project, you'll learn one way of measuring the distance without...

Earth's atmosphere, the ocean of air that blankets the planet, is mostly nitrogen and oxygen, with small amounts of other gases. How much oxygen is present in air at sea level? Is air high up in the Appalachians or Rockies? Atop Mount...

The sun sometimes releases huge bursts of electrified gases into space. These bursts are called coronal mass ejections (or CMEs). When CMEs are directed towards Earth they can generate auroras, the spectacular atmospheric displays also...

Plants need nitrogen to build proteins and nucleic acids to grow healthy stems and leaves. Though the Earth's atmosphere is made up of 79% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. In this...

Even though many cities have recycling programs, a lot of trash still ends up in the dump. Find out which materials will break down and which materials won't. Will the results of this experiment change which products you often buy?

Plants need nitrogen to build proteins and nucleic acids to grow healthy stems and leaves. Though the Earth's atmosphere is made up of 79% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. In this...

Our home, Earth, is a living planet. Earthquakes and volcanic eruptions are proof that the geological forces that shaped our planet and created the land masses are ongoing. An amazing example of geologic activity that is less damaging is...

You might know that we are able to get free energy from the Sun, the wind, and water, but we can also get free energy from Earth itself. This source of energy is called geothermal energy and it is all about taking advantage of the heat...

The oceans are a precious natural resource, part of Earth's carbon cycle. But what happens if the oceans absorb too much carbon dioxide? Many scientists are concerned that the increased absorption of carbon dioxide is causing them to...

Renewable energy is the energy that is extracted from natural sources, such the Sun (solar), earth (geothermal), wind, and water (hydropower). These sources are renewable because they can be replenished by the same natural sources within...

Nematodes, also called roundworms, are the most abundant animal on Earth and can be found in your back yard, playgrounds, and many other places. This lab involves isolating nematodes from several soil samples to discover the best...

Everything on our planet is linked by a giant recycling system called the biogeochemical cycle. How our planet recycles and reuses everything we need to support life is explained by making a miniature biosphere in this lab. You will also...
