When Your Sniffer Snoozes, You've Got Olfactory Fatigue

Science Fair Project Idea

Scientific Method

The holidays are a wonderful time, when lots of good foods and good smells come from the kitchen. But have you noticed that if you stay in the kitchen awhile, you no longer notice the delicious smells? Don't worry! Your nose is not broken, you are just experiencing olfactory fatigue—basically, that's when your nose takes a nap. But what is behind olfactory fatigue and what happens when you experience it? Does a person's sense of smell "get tired" in the same way for different smells? Put… Read more

You Are What You Eat!

Science Fair Project Idea

Scientific Method

Thinking about improving your sports performance? Want to help friends and family make the most of their physical fitness activities? One factor to consider is food! Whether you realize it or not, what you eat does change your body! It affects how you feel, and can even change how you perform in sports. This science fair project will help you explore the link between what goes in your mouth and what your legs and arms can do. Read more

Can Herd Immunity Combat Viral Epidemics like COVID-19?

Science Fair Project Idea

Scientific Method

One strategy you may have heard suggested for dealing with the COVID-19 epidemic is to let nature take its course and let COVID-19 infect enough of the population for us to reach the herd immunity threshold. Does this make sense as a public health strategy? You can explore this question scientifically using SimPandemic, a free online tool for modeling infectious disease outbreaks. Before you begin, you will need to know a bit about herd immunity. Herd immunity, sometimes called community… Read more

Can you spot the dot?

STEM Activity

Have you ever wanted to make something disappear (maybe your homework!)? In this activity we will take advantage of the way your eyes and your brain talk to each other, to make colored dots seem to appear and disappear (sorry, it probably won’t work on your homework)! Read more

Deep Knee Bends: Measuring Knee Stress with a Mechanical Model

Science Fair Project Idea

Scientific Method

Are you interested in things like prosthetic limbs and artificial joints that can help people with disease or injury to lead a normal life? Or maybe you're interested in sports medicine or physical therapy? Either way, this project could be a good match for you. Find out how the tension on the knee joint changes as a function of angle by building a simple mechanical model. Read more

Developing Images with X-rays

Science Fair Project Idea

Scientific Method

You have probably had X-rays taken at the dentist's or doctor's office, but do you know how the X-ray images are made? Images made using X-rays, also called radiographs, are considered to be relatively safe to take, even though they are made using a small amount of radiation, specifically electromagnetic radiation. Radiation is energy that travels through space as either waves or high speed particles. Watch this video to learn more about electromagnetic radiation and X-rays. X-rays can travel… Read more

Do Stress Management Techniques Work for Different Types of Stressors?

Science Fair Project Idea

Scientific Method

Have you ever noticed that your heart beats faster when you’re nervous before a big event? How and when does your heart rate slow down back to normal? In this science experiment, you will see if you can use different stress reduction techniques (meditation, yoga, breathing techniques) to determine which type works best for different kinds and intensities of stressors (physical or mental). You can also record other physiological measures, such as blood oxygen and blood pressure, to see how… Read more

Do You Have the Willpower to Taste Something Sour?

Science Fair Project Idea

Scientific Method

If you developed a super-sour candy, drink, or dessert, to whom would you sell it? Do people of all ages love sour, or is there a difference between the sour preferences of kids and adults? In this mouth-puckering science project, you will find out by making batches of lemonade that vary in their sourness and have volunteers taste them! Read more

Have you ever wondered if people of all ages love sour foods, or if age correlates with this preference? There are a lot of different kinds of sour candies and drinks you may have seen advertised before, some having only a mild sour flavor and others that are truly mouth-puckering! In this activity you will investigate if there is a difference between the sour preferences of kids and adults. If you developed a super-sour food, to whom would you try to sell it? Read more

If someone tells you to remember a phone number or address, it can feel like an easy task at first. You repeat the numbers to yourself, either aloud or in your mind. But after just a few seconds, you may find yourself starting to doubt your own memory. Was it 5-7 or 7-5? Our minds are always seeking new and useful information, and as a result, it will try to ‘throw away’ information that seems old or irrelevant, such as a random string of numbers or an address. However, there are… Read more
