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

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

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 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 determines how UV radiation emitted by the sun varies depending on the time of day, using a handheld UV detector

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.

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

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!

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.

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

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.
