We all know that the Moon has different phases, but it can be hard to figure out why. Try this activity to see how the Moon's phases really work.

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.

Calculate the mass of the Earth using the sidereal and calendar period of the Moon and Newton's Law of Universal Gravitation in this physics science project!

How do the phases of the Moon and gravity cause spring tides and neap tides? Does the Sun play a role in the tides? Figure it out in this fun science project!

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

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.
