A great science fair project on solar oven design that helps kids learn about solar power and solar heating.

The objective of this project is to examine the ways in which a passive solar house may contribute to conservation of energy.

What direction should solar panels face? It's not the direction you might think! This free and enlightening science fair project helps kids discover the answer.

This science fair project idea determines whether land or water warms more quickly and investigates how solar radiation increases the temperature of surfaces.

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 project concerns activity happening millions of miles away, on the sun.

Bake some cookies with an oven that collects sunlight and traps the shorter wavelengths (heat!).

All you need are pencils, paper and some scissors to get started on this easy and fun game to review astronomy information, or other types of study concepts.

This science project challenges students to take learned information about weather and climate control and apply it to come up with creative ideas of their own.

This science fair project looks one of the most important factors affecting seed germination: water. A fun and easy plant biology experiment for 3rd graders.

Here is a fun middle school science project on factors affecting solubility. Learn how dissolved solids can "crash out" to form crystals when conditions change.

This simple experiment serves as an introduction to the greenhouse effect.

This fun science project helps to investigate how much water can a plant take up and release in a certain period of time through the process of transpiration.

The objective of this science project is to determine the relationship between carbon dioxide gas and the temperature of the atmosphere.
