This experiment will explore the possibility of a connection between lunar cycles and how humans are affected.

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

Explore the craters, maria, and highlands on the surface of the Moon! In this fun science project you'll create a 3-D model of the moon using paper mache.

This fun science fair project for 8th grade demonstrates what Kepler's 3rd law predicts about a planet's orbital period and its distance from the sun.

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

Consult astronomers for opinions and advice. Devise a mathematical argument regarding the probability of other planets supporting extra-terrestrial life.

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

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.

The moon doesn't produce its own light, so why can we see it shining in the sky? Learn about reflection and planetshine in this fun and easy science project!

The purpose of this science fair project is to investigate whether we can simulate how craters are formed and predict their size and shape.

The objective of this project is to evaluate whether a top will spin at different rates during different phases of the moon.

What cause the phases of the moon? Make a model to see how the positions of the Sun, Moon, and Earth cause the crescent, gibbous, quarter, full, and new moon.

What causes the seasons to change? Kids find out by modeling the earth's tilt using a globe, flashlight and graph paper in this cool science fair project idea.

This project concerns activity happening millions of miles away, on the sun.
