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

Make Your Own pH Paper

Science Fair Project Idea

Scientific Method

This is a simple "kitchen chemistry" project about acid/base chemistry. Scientists measure the acidity or alkalinity of a solution using a logarithmic scale called the pH scale. In this project you'll learn about the pH scale, and you'll make your own pH indicator paper using a pH-sensitive dye that you'll extract from red cabbage. You can use your pH paper to measure the acidity/alkalinity of various household solutions. Read more

Have you ever wondered how crystals are made? 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 activity, you will compare the size and shape of crystals grown at different temperatures. With just water and Borax, a household cleaning product, you can discover the method for growing large, pure crystals! Read more

Is Plant-Based Milk as Protein-Packed as Dairy Milk?

Science Fair Project Idea

Scientific Method

What kind of milk do you drink in your household? Do you drink 2% dairy milk, whole dairy milk, or plant-based milk like almond milk or soy milk? Have you ever considered why you drink it? As more sustainable and alternative food options become increasingly available, people are interested in the nutritional value of plant-based foods. The US government dietary guidelines state that dairy milk is a good source of protein. Are plant-based milk sources also a good source of protein? In this… Read more

Big Pieces or Small Pieces: Which React Faster?

Science Fair Project Idea

Scientific Method

Some chemical reactions occur explosively fast, others may occur almost imperceptibly s-l-o-w-l-y. This project explores what effect the particle size of the reactants has on the speed of a chemical reaction: production of carbon dioxide gas by an Alka-Seltzer® tablet. Read more

Have you ever wondered why ice cubes in your cold drink become gradually smaller, or why their surface becomes smoother as they melt? Does ice always melt this way? In this activity, you will use water balloons to create giant ice balls and observe how they melt. Can you predict the effect a bit of salt will have on your giant ice ball? 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

Make Your Own Markers

Science Fair Project Idea

Scientific Method

Do you ever wonder how markers are made? Where do all of those colors come from? Many of the colorful dyes we use come from plants. Could you create vibrant colored natural dyes? Could you turn these dyes into art supplies? You can! In this science project, become a scientist and engineer and make your own marker using homemade plant dye! Read more

Colorful Chemistry Creations: Make Your Own Sun Print with Color and Sunlight!

Science Fair Project Idea

Scientific Method

You've probably heard of hand prints and fingerprints, but what about a Sunprint®? To make a Sunprint, place an interesting object on a special sheet of Sunprint paper, expose it to the sun for a few minutes, immerse the paper in water, and watch as a permanent image appears! Sunprint paper can be used to make beautiful and eerie prints, using just sunlight and water. Sunlight is actually a mixture of different colors of light. In this chemistry science fair project, you will test which… Read more
