Skunk Attack! Test Different Remedies to Remove Skunk Odor

Science Fair Project Idea

Scientific Method

Have you or one of your pets ever been sprayed by a skunk? Hopefully not, but if you have, you probably know that the smell can be very unpleasant and hard to get rid of. There are many "folk remedies" for getting rid of skunk scent, but if you ever do get sprayed by a skunk, how will you know which one to try? In this science project, you will test the ability of various mixtures to remove the bad scent from rags that have been contaminated with bottled skunk scent, and determine which one… Read more

In the springtime it can be easy to spot flowers in a dazzling array of colors at flower gardens and in plant nurseries. And with Mother’s Day just around the corner, stunning flower bouquets are even more readily available in stores. Have you ever wondered what pigments make a flower appear a certain color to us? For example, what pigments make a rose be a deep, rich shade of red? Do different flowers use the same pigments? In this activity you’ll get… Read more

Study Chirality with a Homemade Polarimeter

Science Fair Project Idea

Scientific Method

Some molecules can be either left- or right-"handed." The left- and right-handed molecules have the same number and type of atoms, and their chemical structures look identical, but they are actually mirror images of each other. Many naturally occurring molecules have this property, called chirality. Chiral molecules can interact with polarized light in an interesting way—they rotate the plane of polarization. This chemistry science fair project describes how to make a homemade polarimeter… Read more

You’ve probably seen the reaction that happens when you add Mentos candy to a diet soda. The resulting eruption is powerful enough to be dangerous, and is the source of many online videos! While many people are familiar with this reaction, few of them understand why it takes place. The Mentos + Soda reaction is not actually a chemical one, but a physical one called ‘nucleation’. In this activity we will explore nucleation in soda at a smaller scale by adding some unusual… Read more

You might have heard the saying “not everything is as it seems.” Something might look great from far away, but when you take a closer look, it might not turn out to be as beautiful as you thought! In this activity, you will create the opposite experience—you will turn a spoon blackened with soot into shiny silver. Even though it is only an illusion, you will not know it when you see it. Try it out for yourself! Read more

Where does CO₂ come from and how does excess carbon dioxide in the atmosphere affect the ocean and aquatic life? In this lesson students are introduced to the carbon cycle and explore pH and acidification with hands-on experiments. They then connect their experimental data with real-world data to evaluate claims about carbon dioxide and ocean acidification. Finally, students are introduced to how different companies and research groups are using green chemistry to build carbon capture… Read more

Have you ever mixed sand and salt together and wondered how you could separate them again? If you had to separate them, would you have nightmares of tiny tweezers, a magnifying glass and hours spent picking grains of salt and sand apart? Don't be afraid, there is another way! Using the differences in solubility between salt and sand, you can find the simple "solution" to this problem. Read more

Baking Soda Weight Loss

STEM Activity

Baking soda is not only great for cooking; it is also a useful chemical for science projects. You have probably heard about and maybe even used the baking soda/vinegar reaction to make volcanos erupt, shoot bottle rockets up in the air, or to detect acids and bases. However, there are many more chemical reactions that you can explore with the help of baking soda. One of them is called a decomposition reaction, which makes baking soda lose weight! Want to find out how it works? Then try this… Read more
