Check out this cool science project idea to learn about rocks and explore the cycles of formation, breakdown, and reformation of rocks in the Earth's crust.

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.

In this science fair project, young children notice and track changes in trees throughout the year.

This project determines the age of a tree using a growth factor chart instead of cutting the tree down to count the rings in its base.

Science fair project that determines whether landscaping fabric impacts the ability of plants to receive water.

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.

Learn how to be a bird scientist in this simple project of watching feathered friends in their habitat.

Science fair project which compares the rate of temperature change and the maximum temperature as a result of the angle of light radiation.

Check out this cool science project idea to explore how temperature creates annual rhythms that govern plant growth.

The purpose of this project is to determine if there are fluctuations in the rising and the setting of the sun and the position of the earth as it rotates.

Compare ability of selected materials to block UV-A radiation. Shine black light though glass at detecting beads underneath. Note color intensity.

Students explore hot desert plant adaptations in this cool science fair project by observing how these organisms prevent excessive transpiration.
