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.

Help your young scientist celebrate the wonders of the night sky in the comfort of your own home.

Many ancient cultures used the rising or setting sun to create calendars. Observe the setting sun once a week to come up with your own solar calendar!

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!

Using a toy race car kids create a visual model of the Doppler Effect.

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.
