Science fair project that examines condensation and the conditions needed in order for dew to form.

Kids learn about examples of mechanical weathering and conduct an experiment with seeds and plaster in this cool geology science fair project idea.

Climates with more snowfall have more coniferous forests and fewer deciduous ? Learn about how pine trees in a coniferous forest adapted to withstand snow.

Gymnosperms are coniferous trees that reproduces using pine cones to spread seeds. Check out this simple pine cone experiment to learn about the process!

Find the North Star, and measure your latitude! The purpose of this science fair project is to find latitude and learn about geographic locations.

Science fair project which compares the rate of temperature change and the maximum temperature as a result of the angle of light radiation.

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

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

Science fair project that examines how temperature affects density and how density in turn affects the behavior of helium gas.

The goal of this evaporation experiment is to learn about how different external conditions affect drying time.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

Learn about the role of Earth's rotation on the Coriolis Effect and hurricanes in this science project. Model the Coriolis Effect on a hurricane's direction.

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

This project determines the age of a tree using a growth factor chart instead of cutting the tree down to count the rings in its base.

Get this cool science fair idea to explore how arctic tundra animals change their behavior and adapt to survive in long, cold winters.

In this science fair project, students make their own rain gauge to measure rainfall.

What's the relationship between temperature, air humidity and static electricity? Kids will find out with this free static electricity science fair project.

This science fair project focuses on a polymer called hydrogel super absorbent crystal which absorbs water, swelling to many times its original size.
