What is the hydrologic cycle and how does it work? Check out this fun and easy science project where you will model and learn about Earth's water cycle!

Science fair project that uses distillation to convert salt water into fresh water.

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

This science project idea determines whether cold water boils faster than warm water.

Most people assume that cold water freezes more quickly, but could that be false? Does hot water freeze faster than cold water? Let's find out!

Chlorine and chloramine are added to our tap water to kill harmful microorganisms. What is the best way to filter these disinfectants in your drinking water?

Science fair project that compares the freezing temperature of salt water and freshwater in order to learn about supercooling and condensation nuclei.

Help your first grade scientist learn about metamorphosis by observing the life cycle of some interesting creepy crawlies.

Have fun with bubbles and find out why there are bubbles in your tap water in this cool science fair project idea.

The objective of this science project is to examine the factors that affect the dispersion of oil in water, including water agitation.

This science fair project idea creates an underwater habitat and explores the basic needs of living things under water.

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

Blend science and math to explore a very important first grade social studies question: does our planet contain more land or more water?

In this science fair project idea, kids make water dance on the surface of a hot pan with the Leidenfrost Effect.
