Have you ever opened a fresh bottle of carbonated water or soda, poured a glass of it, and just watched as the bubbles fizzed upward in the glass? Have you ever wondered what those bubbles are? They're made of carbon dioxide gas, which was packed tight in the soda before you opened the bottle. Not only can that carbon dioxide gas give you a fizzy drink to enjoy, but it can also give you a show. How? By making candy conversation hearts "dance!" Along the way you will discover some of the fun… Read more

Have you ever dyed eggs? Turning eggshells from white into different, dazzling colors can be a lot of fun! People often do this using dye tablets to make different colors in a liquid bath. They then dip the egg into the liquid and wait till it turns the desired color. Eggs can be dyed in many other ways, and one neat method uses silk ties. Sounds strange to use clothing to dye eggs, right? But it actually works really well! In this activity, you will dye eggs with silk ties and… Read more

When discussing material properties, most of us usually think of solid materials and material properties such as hardness, flexibility, or strength. However, liquids are characterized by distinct properties, too. Some of these properties overlap with those of solids, like density or transparency, but others are more specific to liquids. Viscosity—the resistance of a fluid to flow—and surface tension, are two examples of properties that are specifically used to characterize liquids.… Read more

Keep Your Candy Cool With the Power of Evaporation!

Science Fair Project Idea

Scientific Method

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 project, you'll use the energy produced when water evaporates to cool down chocolate-covered candy so it doesn't melt. Read more

Have you ever looked at pictures of murals on buildings from hundreds of years ago and wondered how they were created? Fresco is a type of painting that has been used for thousands of years and involves painting on wet lime plaster. This activity explores one aspect of the science behind this unusual technique. See how science can help you become a more versatile artist! Read more

A Soluble Separation Solution

Science Fair Project Idea

Scientific Method

Have you ever mixed together salt and sand? It is fun to see how all of those tiny grains of salt and sand mix together! But what if you had to separate them out again? Do you have nightmares of tiny tweezers, a magnifying glass, and hours spent picking grains of salt and sand apart? Do not be afraid, there is another way! In this chemistry science project you will use the differences in solubility between salt and sand to find out the simple "solution" to this problem. Read more

Are Enzymes in Laundry Detergents Effective Stain Removers?

Science Fair Project Idea

Scientific Method

Some laundry detergents have added enzymes that break down proteins, helping to remove them from the cloth fibers, and thus remove stains. You can perform a scientific test of these enzymes' stain-fighting ability. Do background research on the enzyme(s) in the detergent, and on the substances you choose for making the stains. Try to predict for which substances the enzymes will be effective. Cut a piece of light-colored cotton cloth into identical 10 cm squares. Choose different… Read more

Does Wet Hair Float or Cling?

STEM Activity

Have you ever noticed how hair moves freely when it is under the water, but clings together as soon as it emerges out of the water? Not only human hair does this; when wet dogs shake themselves after a swim, their hair clings together in strands. Try this activity to see why wet hair is far less fluffy than dry hair! Read more

Polymer Permeability: Which Plastic Wrap Prevents Evaporation Best?

Science Fair Project Idea

Scientific Method

There are three different kinds of polymers used for kitchen plastic wrap: low density polyethylene (LDPE) (e.g., Handiwrap or Glad Wrap), polyvinyl chloride (PVC) (e.g., Reynolds PVC Foodservice Wrap or Boardwalk PVC Food Wrap Film) and polyvinylidene chloride (PVdC) (note: Saran Wrap used to be made with polyvinylidene chloride, but has switched to polyethylene. You will need to search for another brand that uses PVdC if you want to test it). Which of these materials is least permeable to… Read more
