Alka-Seltzer® tablets fizz furiously when dropped into water. The moment the tablet starts dissolving, a chemical reaction occurs that releases carbon dioxide gas. Can you make Alka-Seltzer fizz faster or slower by changing the temperature of the water? How big of a difference in the rate of a chemical reaction can temperature make? Read more

If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

What color is grape soda? If you pour it into a clear glass you can easily see it is purple, but that is usually not its natural color. Manufacturers add red and blue dye to the soda. The dyes mix together and you get purple soda. What if you wanted to un-mix the dyes, could you? Yes! In a chemistry laboratory, using a technique called column chromatography, you could separate the two dyes again. But what about at home, can you use low-tech supplies to do the same thing? In this science… Read more

Does your skin get dry? Or do you know someone with dry skin? Dry skin can be a real medical problem for some people. You may have seen many kinds of lotions, creams, and ointments advertised as restorative for dry skin, especially dry hands. But how well do they work? And which ingredients are most important in making them work? In this science project, you will create a model of human skin using JELL-O® and test how well skin moisturizing products with different ingredients keep the… Read more

Cake, cookies, pie, ice cream, hot chocolate, lemonade... Yum! What do all these delicious treats have in common? Sugar. In addition to providing sweetness, sugar adds bulk, flavor, and structure to foods. But is it necessary to add sugar to achieve sweetness? Can the same sweetness be achieved using sugar substitutes like artificial or natural sweeteners? In this project, you will test sugar and sugar substitutes and compare the sweetness of each in relation to sugar. In the end, your day will… Read more

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
