Measuring Surface Tension of Water with a Penny

Science Fair Project Idea

Scientific Method

Did you know that even though water is a liquid, it isn't always able to get into little cracks and crevices? So how do clothes go from caked with mud to clean? How can dishes go from greasy to glistening? With a few simple household items, you can find out! Read more

Paper Chromatography: Is Black Ink Really Black?

Science Fair Project Idea

Scientific Method

Have you ever looked at sunlight through a prism? If so, you know that the prism can separate the sunlight into many different colors of light — a rainbow. Like sunlight, chemical mixtures can also be broken into their component parts. One way of doing this is a simple technique called paper chromatography. What do you think you will see if you use paper chromatography to look at the components of black ink? Is black ink just black? Find out for yourself! Read more

Crazy Crystal Creations: How to Grow the Best and the Largest Crystals

Science Fair Project Idea

Scientific Method

Crystals come in all different shapes and sizes. However, the purest and cleanest crystals are usually also the ones that grow to be the largest in size. In this science fair project, you will compare the size and shape of crystals grown in three different temperature conditions: room temperature, in the refrigerator, and in an ice bath. With just water and borax, a household cleaning product, you can discover the best recrystallization method for growing large, pure crystals. Read more

Explore the Mixing Behavior of Liquids

Science Fair Project Idea

Scientific Method

Have you ever wondered why some liquids mix together easily, like when you mix different juices to make a fruit punch, while others do not mix at all, like oil and water? What happens to liquids when they are mixed depends on their mixing behavior. Some liquids blend, whereas others form separate layers. If you do it right, you can even stack liquids on top of each other just like solid objects! Want to see for yourself? In this science project, you will investigate the mixing behavior of… Read more
