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!

Help your child celebrate the summer and the sun by making a sandy seascape.

How do you tell time without a watch? Use the sun! This simple activity will show your child how to build his own sundial.

Prove that the Earth is not flat. The objective of this science fair project is to measure the angle of the sun and calculate the circumference of the Earth.

This science fair project idea examines whether the colors of the spectrum respond differently in the thermal aspect when radiated by the sun.

This science fair project idea discovers if an artificial light source will yield the same plant health and growth rates as light from the sun.

In this cool science experiment, learn about magnetism and poles, and test magnet strength to find out if two magnets are twice as strong as one.

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.

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!

Take advantage of the spring and summer sun in this arts and crafts activity that has your learner creating pretty flower prints.

This experiment works due to a simple principle: plants need light. Build a shoebox maze and watch the plant work though the obstacle course, searching for sun.

Does your child always demand to know why the sky is blue, how the sun moves across the sky, or where wind comes from?

In this fun science fair project, make two different scale models of our solar system using Astronomical Units and planets' relative size!

This project compares the strength of one, two, and three-ply toilet paper.

Is it solid or liquid? Create oobleck and witness the amazingly weird oscillation between the two!

In this science fair project, young children discover what happens when two fluids that have different densities get together.

In this experiment, your child will create two compost bins and see if he can determine what attracts fruit flies.

Milk is made of water and fat; but how can you separate the two? Find out in this color changing milk experiment.

This science fair project compares the allelopathic affects of juglone, a chemical agent produced by the Black Walnut tree, on two plants.

In this popcorn experiment, students can explore how two things made out of the same material can have very different appearances and densities.
