This science fair project investigates why the number of visible stars changes from place to place.

Science fair project that tests the correlation between outdoor temperature or weather conditions and the number of visible stars at night.

Science fair project which helps you determine your latitude by using an astrolabe, which measures the angle between the North Star and the horizon.

What is a barycenter? Kids learn how gravity and mass influence the orbit of binary systems like planets and moons or stars and planets in this cool experiment.

In this free science fair project, build a star clock and learn how to tell time on a clear night by observing the big dipper!

The goal of this science fair project is to identify the galactic center of the milky way using globular clusters, as found through Google Earth.

Science fair project that explains and demonstrates the parallax principle.

This science project lets students explore the number of spots on a ladybird and how to treat ladybugs with respect.

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.

In this science fair project, students investigate the applicability of Benford's Law to many sets of everyday data.
