Kids will build a turtle habitat in order to observe the climate preferences of this cold-blooded reptile.

The crust is fun for kids to mix and roll out, and the filling overflows with vitamin and anti-oxidant packed berries!

This science fair project idea deals with the qualities of shade on a sunny day.

In this science fair project, we learn how air molecules move as a result of density, convection, and air currents.

The next time you've got a restless second grade earth scientist on your hands, use this experiment to demonstrate crystals and make a tasty treat, too!

Learn how to make a hygrometer to measure relative humidity in this project. Make a sling psychrometer hygrometer with gauze, thermometers, and a bottle.

Kids will learn about insulation, heat conduction, and the economic benefits of energy efficient windows in this cool science fair project.

This science fair project idea identifies clouds as a means of predicting the weather.

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.

In this cool project, create a lighted, scale model of the different layers of the Sun, including the core, radiation and convection zones, and photosphere.

Kids will learn how to measure the viscosity of liquids by making their own homemade viscometer in this great science fair project idea.

Science fair project that examines how yeast grows, and which conditions allow for optimal growth. What types of nutrients does yeast prefer?
