Learn about the layers of the Earth and make a model! Create a earth layer book, cake, or clay diagram.

In this project, you'll build a model of the earth, complete with all seven continents and four major oceans.

Prove that the Earth is not flat. The objective of this science fair project is to measure the angle of the sun and calculate the circumference of the Earth.

This science project has students collect wood samples and invent new uses for different types of wood based on its properties.

Science fair project which measures the shadow cast by a meter stick at various times in order to predict the circumference of the earth.

What if the shape of the Earth weren't spherical? How does its shape affect our gravity, climate, and tides? Model these questions in this cool project!

Calculate the mass of the Earth using the sidereal and calendar period of the Moon and Newton's Law of Universal Gravitation in this physics science project!

The purpose of this project is to determine if there are fluctuations in the rising and the setting of the sun and the position of the earth as it rotates.

The goal of this science fair experiment is to demonstrate the effects of air pressure on objects and analyze applications of air pressure principles.

This project uses science and art to help students learn and teach others about Earth's endangered and extinct species.

Measure the speed of the earth's rotation using protractors and meter sticks. This science fair project measures the angle of the sun in relation to earth.

In this cool elementary school science fair project idea make a model to learn what happens to the Earth's surface when ice moves over land.

This science fair project outlines the uses of gold and explores the monetary value of gold.

see whether all liquids evaporate at the same rate. In other words, does water evaporate at the same rate as juice?

In this project, all you need is a protractor to learn how to use the altitude of Polaris to find latitude on Earth. Polaris is also known as the North Star.

How is NASA able to launch something into orbit around the Earth? Learn about the relationship between gravity, speed, and orbit in space in this cool project!

This science fair project idea discovers which parts of the body are more sensitive to touch than other parts of the body.

This science fair project idea focuses on two classes of sugars monosaccharides (fructose) and disaccharides (sucrose or table sugar).

How clean is the air we breathe? The answer might surprise you. Learn how to investigate local air quality with this cool science fair project.

Learn all about balance and motion as your child designs a corn maze!

Use popcorn in this tasty experiment to explore the five senses at home with your kindergartener!

This fun science project explores the climate change over the course of the history of Earth and helps construct a diorama representing a geologic time period.

This science fair project idea examines the distance a person travels on an average day and to relate that to an understanding of the size of the Earth.

This experiment explores the trend of reactivity in the alkaline earth metals as you go down the second column of the periodic table of elements.
