The Cold Wash Challenge: Testing How Well Enzymes Work in Laundry Detergents

Science Fair Project Idea

Scientific Method

What do you think are some of the most common stains on clothes? If you thought of grass, grease, ketchup, blood, or toothpaste stains, you are correct. Everyday activities like eating, playing outside, or doing sports can result in a lot of dirty laundry. Luckily, we have laundry detergents that can get our clothes clean again! Some of these detergents contain enzymes that are intended to boost cleaning power. In this science project, you will investigate how effective biological and… Read more

‘Think fast!’ someone says, as they toss a ball toward you. You catch the ball, but do you really ‘think’ about doing it? Probably not! Most likely you raise your hands to catch the ball without ever consciously thinking about it. How does this happen? Lucky for you, your brain is able to react to things in your environment without you having to consciously make a decision about how to react. There are many ways to measure the speed of this type of reaction, and in this… Read more

Transforming Bacteria to Make Colored Pigments

Science Fair Project Idea

Scientific Method

Can bacteria be altered to produce life-saving insulin for diabetics? Or change color to indicate the presence of a harmful toxin? Yes, it can! Using biotechnology, scientists work daily on problems like these. It starts with selecting a gene you want bacteria to produce and creating a sequence of DNA that has that gene and a promoter that will help express it at the right time and at the right levels. The next hurdle is actually getting this engineered DNA into the bacteria and… Read more

Watching Nuclear Particles: See Background Radiation Zoom Through A Cloud Chamber

Science Fair Project Idea

Scientific Method

Do you realize that you are constantly bombarded by particles? You do not feel them, you cannot see, hear, or smell them, but they are always there! These particles — collectively called background radiation — might even travel through you without ever interacting with the molecules in your body. In this science project, you will build your own cloud chamber to prove the existence of background radiation. You will then use your cloud chamber to determine if the background… Read more

Weekly Science Project Idea/Home Science Activity Spotlight: Shake Up Some Butter

Blog Post

In this week's spotlight: a pair of projects that investigate the science of butter-making, a process you might even call butter-shaking! In these hands-on food science projects and activities, students make their own butter and investigate to find out what role (if any) temperature plays in the process. You and your family can shake up some butter to use with tomorrow's breakfast, but will you have better luck using cold or room-temperature cream? Get shaking to find… Read more

What A Drag!

Science Fair Project Idea

Scientific Method

What makes some objects more streamlined than others? Find out which ordinary objects around your house are made to move smoothly through the water in this easy science fair project. Which objects will produce the most drag when pulled through the water? Read more

What's Going On Behind Those Puppy-Dog Eyes?

Science Fair Project Idea

Scientific Method

Have you ever wondered what goes on in your dog's mind? Even though humans have the benefit of language, trying to understand another person's thoughts can be hard enough sometimes. Your dog can't talk, so how can you find out what its brain is capable of? The obvious answer is to study its behavior. This project will show you some behavioral tests you can use to measure canine I.Q. Read more

Which Acne Medication Can Really Zap That Zit?

Science Fair Project Idea

Scientific Method

Have you ever wondered where acne comes from and how you can treat it? One major cause of acne is the colonization and infection of clogged pores with bacteria. In this science project, you'll test different acne medications and treatments to determine their effectiveness at killing bacteria. Read more

Which Materials Can Catch a Bubble?

Science Fair Project Idea

Scientific Method

Can you catch a bubble with your hands? What if you use another material, like a piece of paper or aluminum foil? Try this science project to find out which materials can catch a bubble without popping it. Read more
