There are many occasions to light candles. When you did, have you ever looked closely at the flame? Which part of the candle is actually burning? Can you tell? Is it the wick, the solid wax, the liquid wax or something else? In this activity you will light some candles to find out—no special occasion required! Read more

Ever wondered how the boba in bubble tea are made? Bubble tea or boba tea is a sweetened drink made of flavored tea, milk and bubbles. The translucent, squishy bubbles called boba are remarkably easy to make. You only need three ingredients: tapioca flour, water, and brown sugar. The skill lays in one little detail: the temperature of the water used. Curious? Try it out and make bubble tea from scratch! Read more

Have you ever gone to pour yourself a cup of milk, and all you get is clumps? What happened to the milk is called coagulation, which is the mechanism that occurs when proteins in the milk clump together. While you do not necessarily want this in your milk, without coagulation (or curdling), there would be no cheese or yogurt, which is why it is a very important process in the food industry. Wonder how you can make milk curdle? Do this activity to find out! Read more

Saturated Solutions: Measuring Solubility

Science Fair Project Idea

Scientific Method

Many essential chemical reactions and natural biochemical processes occur in liquid solutions, so understanding the chemical properties of liquid solutions is fundamentally important. This project asks the basic question, how much of a substance can dissolve in water, for three different substances: ordinary table salt, Epsom salts, and sugar. Read more

Do you like cooking? If you have helped in the kitchen at home, you have probably heated up lots of liquids, like water, milk, and soup. Did you notice that once the solution boils, a lot of steam develops; and have you ever wondered what the steam is made of? What happens to all the substances, such as sugar or salt, that are dissolved in the solution you are boiling? Do they boil off, too, or do they stay behind in the solution? In this activity, you will build a distillation device that… Read more

Use a Calorimeter to Measure the Heat Capacity of Water

Science Fair Project Idea

Scientific Method

Along with its many other interesting properties, water has the ability to absorb a lot of heat energy, while only experiencing a relatively small change in temperature. One way this property affects us directly is that our bodies don't change temperature rapidly on hot or cold days, since we are made up of mostly water. In this chemistry-with-an-electronics-flair science fair project, you will determine how the temperature of a small volume of water changes as you add precise amounts of heat… Read more

Have you ever wondered why salt is used to de-ice roads? Did you know that snow sticks more readily to pavement that has been treated with salt? Why would this be the case? In this activity, you will use the same principles to hoist ice cubes with a piece of string. Is it possible to do this without getting your hands cold? Try the activity and see what a pinch of salt can do! Read more

What's the Best Exposure Time for Sun Print Paper?

Science Fair Project Idea

Scientific Method

Did you know you can make paintings or drawings using sunlight? You can do it by leaving objects on top of special sun print paper until the light creates an imprint of the objects. How does this process work? How long should you leave the paper in the sun to get the best result? What does any of this have to do with the process of making the microchips that power our phones and computers? Try this project to find out! Check out this page for more science projects related to this process. Read more

What's the Point of Boiling?

Science Fair Project Idea

Scientific Method

You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar or salt) that are dissolved in the water? Do they boil off too, or do they stay behind? Read more
