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

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

Don't Get Burned! Measure the UV Index at Different Times of the Day

Science Fair Project Idea

Scientific Method

It's true that the light from the Sun provides the heat and light we need to survive here on Earth, but it also poses a threat. Ultraviolet (UV) rays in sunlight cause damage that can lead to early skin aging and even skin cancer. In this science fair project, find out when you need the most protection from UV rays by using a personal UV monitor to measure how the level of ultraviolet light changes during different parts of the day.

Have you ever been puzzled by a faint noise nearby, trying to discover what it is? Maybe you turned your head or cupped your hand behind your ear, hoping to hear the sound better. What if we could make this cup huge? After all, some animals with exceptional hearing have big ears, like a serval (a type of wildcat), which can hear a mouse wiggling its way underground. Birds are even believed to use their entire head as an outer ear. In this activity, you will design and test your newest hearing… Read more

Have you ever coughed, felt short of breath because you were sick, or felt it was hard work to take a breath? Maybe you have watched someone gasping for air. At times, these events can feel scary! This activity explores how mucus and fluid in the lungs or airways changes our breathing using a simple lung model. It can help you understand why symptoms like coughing and being short of breath happen. Read more

Did you know that there is a type of clam that has thousands of small eyes covering its body? It’s called the Tridachna gigas, and it lives in the South Pacific Ocean. Although it has a lot of them, the Tridachna gigas’ eyes are fairly primitive compared to ours (so don’t be too jealous that you don’t have thousands of eyes too!). In modern times, all vertebrate animals (including humans) have two eyes. Humans have developed an amazingly complex visual processing… Read more

What happens when you get food poisoning or the flu? How does our body fight an infection when we get sick? In this lesson, students will build a model of our immune system to find out how our body responds to invading bacteria or viruses that cause diseases and to investigate the role of memory cells.

Did you know that you have a blind spot in your eye? In fact, every person has an unavoidable blind spot in each of their eyes. This doesn't mean that you see a constant black spot in your field of vision though. Normally you don't notice these blind spots at all, however there are some ways how you can make these blind spots visible. This activity will show you how to find them. Can you find them or not?

Have you ever wondered how a decision to move your arm can make your arm move? When your brain creates a command to move your arm, nerves pass along the command and muscles in the arm contract as ordered. These muscle contractions make your arm move. But could your arm move without a command from the brain? This activity is a fun and surprising way to find out! Read more
