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.

Collect meteorite dust with a magnet in your very own backyard! The objective of this science fair project is to gather meteorite dust to study outer space.

Will storing cucumbers and tomatoes in the fridge destroy their unique flavors? Find out in this science fair project idea!

Science fair project in which you will start a fire from scratch without using matches or a lighter.

Can you dig it? This science experiment isn't for kids who like to keep their hands clean.

This science fair project idea examines whether adding gelatin causes a solid to have a higher melting point and/or melt slower.

Science fair project that compares the freezing temperature of salt water and freshwater in order to learn about supercooling and condensation nuclei.

Is it amplitude? Weight? Length of string? Kids will discover what factors changing the period of a pendulum depends on in this fun and easy physics experiment.

What does a raindrop look like when it splashes on the ground? Is each raindrop unique like snowflakes? Find out how raindrop size varies in this experiment.

In this simple circular motion experiment, you'll observe tangential velocity and learn about how acceleration and centripetal force affect an object.

In this activity, your student will be invited to build a chair out of building blocks that is designed to meet the specific size and shape of a small doll or toy figure.

This science fair project idea explores whether a plastic slinky works as well as a metal slinky when walking it down the stairs.

Learn how different types of soil affect how animal tracks form in this experiment!

Check out this fun science fair project idea for 1st grade: a solar eclipse model that demonstrates total, partial, and annular solar eclipses.

This science fair project idea investigates how a bottom keel helps keep a boat from rocking back and forth.

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

Soil and energy don't go together, right? That would be as bizarre as a pairing of peanut butter and marshmallows! Well, actually...

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?
