What if you could take a single liquid, and change it into a rainbow of colors without using food dye. You can! In this activity you will use red cabbage to make what is called an indicator solution. Indicator solutions can change colors depending on what you add to them. In this case adding something acidic (like lemon juice) will change it to one color while adding something basic (like bleach) will change it to another. Try and see how many colors you can make using different household… Read more

Have you ever wondered how all the food that you eat gets digested? It is not only the acid in your stomach that breaks down your food—many little molecules in your body, called enzymes, help with that too. Enzymes are special types of proteins that speed up chemical reactions, such as the digestion of food in your stomach. In fact, there are thousands of different enzymes in your body that work around-the-clock to keep you healthy and active. In this science activity you will investigate… Read more

Have you ever wished your drawings would come alive and the stick figures or objects on your paper could move around? What sounds impossible actually is not! In this activity, you will make your drawing move around by letting it float on water. What makes this possible is the interesting chemistry of dry erase markers. These markers are usually used to write on white boards or glass surfaces and can easily be erased to make space for more writing or drawing. It turns out that they are also… 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

What's the Best Container for Elephant Toothpaste?

Science Fair Project Idea

Scientific Method

Check out this video from former NASA engineer Mark Rober, where he sets out to reclaim his title for the world's largest and tallest elephant toothpaste reaction. In the video, he experiments with different container shapes and sizes to determine which will result in the most spectacular reaction. You can turn this into a science project of your own! How do differently sized or shaped containers affect the foaming reaction? Can you find an optimal container that makes the reaction go the… 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

Have you ever made a tie-dyed t-shirt? It can be a lot of fun to dye a shirt in bright colors with spiraling designs (especially when it is done on a warm day outside to prevent indoor messes)! In this science activity, you will get to dye a t-shirt with your own colorful artwork using permanent markers. Along the way, you will find out how solubility helps your drawings leave beautiful designs on the fabric. Read more

Have you ever heard about starchy and non-starchy foods? What is the difference? Starchy foods contain the carbohydrate starch, which is converted to sugar (glucose) inside our body for energy production. How do we know which foods contain starch and which do not? There is a simple chemical test that you can do to detect starch, which involves an iodine solution. The iodine solution turns any food that contains starch dark blue. Try this activity and watch it in action yourself! Read more

If you have ever tried to make bubbles using plain water, you may have seen that it does not work. This is because the surface tension of water is too high. When detergent is added to water, it lowers the surface tension so that bubbles can form. Other things can be added to this mixture, such as corn syrup or glycerin, to make a solution that is even better for creating bubbles. In this science activity, you will find out which solution creates the best bubbles! Read more
