Science Buddies: Getting Critical Over Colloids
What is a colloid? If you have made Oobleck out of corn starch and water, then you know that a colloid is a mixture that acts like a solid and a liquid at the same time. This activity helps you determine the critical factors that...

Science Buddies: How Salty Is the Sea?
Have you ever been swimming at the beach and gotten some water in your mouth by mistake? Then you know that the ocean is very salty. Bodies of freshwater also contain some salt, but much less compared to oceans. In this experiment you...

Science Buddies: Put Your Water to Work: Using Hydropower to Lift a Load
Water creates a lot of energy, just look at the Grand Canyon. In this science fair project, you will demonstrate the power of water by converting the kinetic energy in moving water to mechanical energy, which will lift a small weight.

Science Buddies: Heavy Metals and Aquatic Environments
You might know that lead can be toxic, and that you can get lead poisoning from eating or inhaling old paint dust. Lead is called a heavy metal, and there are other sources of heavy metals that can be toxic, too. Silver, copper, mercury,...

Science Buddies: Bubble Ology
Making your own bubble solution is fun, but sometimes the bubbles don't seem to work as well as the solutions you buy in the store. In this experiment you can test if adding corn syrup or glycerin to your bubble solution will make it...

Science Buddies: Keep Your Candy Cool With the Power of Evaporation!
Did you know that your body has a built-in cooler? And it might not be what you think. Sweat is produced when you are hot, but its purpose is actually to cool your body as the water in it evaporates from your skin. In this science fair...

Science Buddies: From Brine to Beverage: Solar Powered Salt Removal
In this science fair project you'll discover how to turn the ocean into a source of freshwater by using the power of the Sun, and the water cycle. You will ultimately find just how salinity affects this process.

Science Buddies: The Power of Heat Is Right Under Your Feet!
You might know that we are able to get free energy from the Sun, the wind, and water, but we can also get free energy from Earth itself. This source of energy is called geothermal energy and it is all about taking advantage of the heat...
