Can flavor change even when you are not adding ingredients, cook or bake it? Try this activity and discover how temperature influences flavor! Read more

Model How R naught (R₀) Shapes an Epidemic

Science Fair Project Idea

Scientific Method

Even during a global pandemic like COVID-19, there are differences in how the epidemic unfolds within communities. Some communities see early, large waves of infected individuals, while others see smaller numbers of infections over a longer period of time, and others may not appear to have an epidemic at all. Could R₀ (pronounced R naught), account for some of this variation? R₀, the basic reproduction number of a disease, quantifies how many people, on average, an infected… Read more

Modeling the Human Cardiovascular System: The Factors That Affect Blood Flow Rate

Science Fair Project Idea

Scientific Method

People often call cardiovascular disease a "silent killer." This disease sneaks up and causes damage, but patients don't realize it—until serious symptoms start. That is why physicians recommend keeping your cardiovascular system healthy. A healthy cardiovascular system gives us the energy and the stamina to do all of the things that we want to accomplish, such as do our best in school and perform well in sports. But what makes a cardiovascular system unhealthy, and what are the… Read more

Motor Imagery Visualization's Impact on Fine Motor Skills for Space Flight

Science Fair Project Idea

Scientific Method

In this science experiment, you will model and test how visualization of a task can change the accuracy of your fine motor skill performance. You will use the small muscles in your hands to model how your body would perform on Earth versus a space launch. Read more

Old Salty: Does Age Affect the Ability to Detect Salt?

Science Fair Project Idea

Scientific Method

Sauerkraut, pickled fish, pickled vegetables, kimchi, corned beef, processed cheeses, smoked lunch meats. Do you like these high-salt foods? What about your grandparents, do they? Do your grandparents seem to like most foods to be a bit saltier than you do? Try this science fair project if you want to find out more about the incredible, edible rock known as salt, and why people vary in how much of it they like to eat. Read more

Take a deep breath: freshly baked cookies, smoke from a wood fire, or a bouquet of roses—your nose is an amazing smell detector! Your sense of smell can not only identify a huge variety of odors, but it is also incredibly sensitive. Think about how easily you can detect if someone in your neighborhood has a barbecue just by smelling hints of smoke from a faraway grill. But how good is your nose when it comes to differentiating individual smells? Do this activity to find out! … Read more

Did you know we use our side vision for many daily activities, like riding a bike, reading or playing basketball? Few people realize they are even using it. Our survival once depended on the quick response of our peripheral vision. A detailed picture, created by our central vision, is only useful in situations where time allows us to focus on the details. But our side vision can help us avoid dangers quickly. In this activity, you will find out how specialized our peripheral, or side vision, is. Read more

Scentsational Memories

STEM Activity

Did you know that approximately 2 million people in the United States have no sense of smell? Lack of smell is a disorder known as anosmia, and can be caused by damage to the nerves that transmit information from your nose to your brain. Our sense of smell serves an important purpose, we use it to distinguish between edible and inedible items in our lives, including fresh or rotten foods, and even particular toxins that have strong, unpleasant smells. In this activity you will test the scent… Read more

Have you ever noticed how the moon appears bigger at the horizon, just as it is rising over the treetops, than it does later in the evening when it is overhead? Of course, the size of the moon does not change, but our perception of its size changes based on where it is in the sky. In this activity, you’ll investigate Emmert’s law, which helps explain the full moon illusion, and estimate the size of the perceived increase in size of the moon at the horizon. Then you… Read more

How many objects do you think you are touching with your hands every day? A lot! Every time you touch something, your hands are able to feel how smooth, cold, warm, or rough the object is. In fact, your hands and fingers are so good at sensing details of shapes and surface textures that they are able to identify an object just by touching and without seeing it! You probably know that already because you have tried that before. Here is the challenge though: Do you think your feet can do the… Read more
