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.

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.

Has your kid noticed how much bigger the moon looks when it's low in the sky? Here's an activity you can do to show them that it's just an optical illusion.

Examine the influence of the phase of the moon on moisture capillarity in garden soil. Measure and record the depth at which water is first detected.

Celebrate Ramadan by creating a crescent moon and star...out of stars! This craft is the perfect way to introduce your child to an important national symbol.

Here's a simple arts and crafts activity to do with your preschooler: make a moon winder toy! All you need is a plastic lid, colored paper, twine, and glue.

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.

Have your little astronaut create her own crater-filled moon with this fun craft project that encourages learning about the final frontier.

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!

Help your second grader observe the phases of the moon, and then let the fun loose: he'll get to chart his observations with marshmallows!

In this science fair project, students evaluate if the phases of the moon affect the way people feel.

The objective of this free science fair project is to examine the way in which the phases of the moon affect circadian patterns in mammals.

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!

Science fair project that demonstrates the different phases of the moon by physically representing them with construction paper and a shoebox

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

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!

Become familiar with ratios and learn how to measure the diameter of the Sun and the Moon in this fun science fair project idea.

This two-ingredient dough, sometimes called "moon sand," is a quick and cheap way to let kids explore their senses, build fine motor skills, and play.

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.

Try this simple 2nd grade science experiment to teach your child about the principles of luminosity and light reflection.

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

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

Teach your child about the importance and peacefulness of Ramadan as she gets creative drawing domes, minarets and prayer halls.

Recreate the fantastic phenomena of solar eclipses with your child using just a flashlight, a quarter, and her very own face!
