This science research project challenges students to think of more effective lobster farming methods.

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

In this science fair experiment, children demonstrate the relationship between the amount of stuff and the amount of pressure in a closed system.

In this project, you will observe and record changes in sunspots over two weeks.

Find out whether packaged seeds actually do expire in this new science fair project idea.

Science fair project which tests various sedimentary, igneous and metamorphic rocks to find out whether one rock family is stronger than the others.

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

In this science fair projects, students will grow out the bacteria that collect on air conditioner filters.

This classic children's game demonstrates how sound travels through air vs. through a solid.

Find out whether cast iron or regular teflon pans heat up faster and also retain their heat longer.

This science fair project idea explores which fruit molds the fastest.
