In this physics project, you'll learn how to find the maximum height of a projectile using some math and trigonometry.

In this cool experiment, learn how to find specific gravity of minerals using liquids of different densities to see which substances and items sink and float.

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.

This tricky building block challenge asks your learner to think creatively. They will work on their divergent thinking skills as they try to fill up an index card perfectly with building bricks.

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