Science fair project that examines how temperature affects density and how density in turn affects the behavior of helium gas.

Here's a fun at-home activity that will help your child strengthen math skills using high and low temperature data, and become a master temperature tracker!

Find out whether cast iron or regular teflon pans heat up faster and also retain their heat longer.

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

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

Check out this cool science fair project idea to explore the risk of mechanical deterioration of artifacts placed in a storage box due to mold outbreaks.

Based on the concept of water's "freezing point," this activity entails the lowering of water's freezing point to chill ice cream!

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