Compare air temperature with the infrared temperature from a reflecting surface at different times of the day, in shade and in sunlight.

How do cold packs work? Explore endothermic reactions by comparing the temperature change that results from various chemicals added to water to find out!

The objective of this science fair project is to examine the cleanliness of salad preparation techniques.

This project compares different liquids and the freezing, melting and boiling points of liquids.

Determine how salinity affects the circulation of warm and cold water. Note whether the warm water mixes or forms a layer with cold water.

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

Check out this fun science project to explore the relationship between solubility, drug absorption, and time required for a drug effect to become apparent.

Learn about emulsification and bile's roles in digestion, and investigate how the digestive enzyme lipase breaks down lipids.

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

Determine whether magic salt is more effective at melting snow than regular salt. Pour one ounce of salt over the ice cubes, compare the melt downs.

The purpose of this science project is to determine which chemical best lowers the temperature of water in a cold pack and if the amount affects its use.

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