Science Fair Project Idea

Scientific Method

The practice of "belly breathing" has been linked to improve mood, relaxation, and even have physical benefits like lowering your heart rate when compared to chest breathing. However, most of the time, we do not think about breathing—our bodies do it automatically. How do you know if you are belly breathing instead of chest breathing? How can you practice and get better at it? In this project you will build your own device to provide visual feedback about how a person breathes, then see… Read more

Minds of Their Own: A Chemical Reaction that Changes, then Changes Back!

Science Fair Project Idea

Scientific Method

Have you ever seen a chemical reaction that makes a solution change color? Probably. But what about a solution that changes color and then changes back, not only once, but many times? Sounds pretty exotic! Whereas most chemical reactions only move in one direction from reactants (starting chemicals) to products, in these rare oscillating reactions, the reaction products appear and disappear for a number of cycles. Because the products are colored, the solution appears alternately blue, then… Read more

Topologies

Science Fair Project Idea

Scientific Method

What do knots, maps, mazes, driving directions, and doughnuts have in common? The answer is topology, a branch of mathematics that studies the spatial properties and connections of an object. Topology has sometimes been called rubber-sheet geometry because it does not distinguish between a circle and a square (a circle made out of a rubber band can be stretched into a square) but does distinguish between a circle and a figure eight (you cannot stretch a figure eight into a circle without… Read more

Testing How Clothing Choices Impact the Behavior of Others Around Us

Science Fair Project Idea

Scientific Method

Do people treat someone differently based on his or her appearance? Specifically, how are their behaviors affected by the clothes a person wears? For instance, if somebody wears a formal suit, do you think others behave differently when interacting with that person compared to if he or she were wearing casual clothes, like blue jeans? In this science project, you will get to try and find out! Read more

What is the Maximum Intermediate Height for a Siphon?

Science Fair Project Idea

Scientific Method

A siphon is a handy device for emptying out a liquid reservoir that has no drain. For example, they're great for cleaning fish tanks. An interesting aspect of a siphon in action is that the liquid flows "uphill" for a portion of its journey through the tube. This project asks the question, is there a maximum height for that uphill part of the siphon? Read more

The Eye of the Beholder and the Mind of the Beheld

Science Fair Project Idea

Scientific Method

The concept of beauty changes over time and often differs among societal groups. How strongly do societal conceptions of beauty shape an individual's self-image? There are many fascinating questions you could choose to explore with surveys on this subject. For example, how well do girls' ideas of what is attractive in boys agree with boys' expectations about what girls find attractive (or vice versa)? Try your survey with different generations to see how conceptions change over time. If you… Read more

Drug Solubility

Science Fair Project Idea

Scientific Method

When you take medicine, it needs to dissolve in order to be passed into your bloodstream to have an effect. On the other hand, the drug needs to be packed into a small, dense pill to make it easier to swallow. How does the delivery method of a drug change how quickly it enters the bloodstream? Compare different brands of a drug to find out which brands dissolve the quickest. Does the pH of the stomach (which is usually between 1 and 2) matter? Compare coated to uncoated pills: does the coating… Read more

Feel Sound With Your Fingertips: Ultrasonic Haptics

Science Fair Project Idea

Scientific Method

Virtual reality headsets can make you see something that isn't really there, but can you feel an object that isn't there? In this project, you will build a device that lets you feel invisible sound waves in midair. Read more

Efficient Propeller Design

Science Fair Project Idea

Scientific Method

How does a helicopter generate enough lift to fly? How does a speedboat get moving fast enough to pull someone on water skis? Here's a project on designing propellers to do the job. Read more

Lunar Crater Counting

Science Fair Project Idea

Scientific Method

Get good photographs of the Moon showing lots of craters and count how many craters you find in a range of diameter classes. One useful source is the Consolidated Lunar Atlas (Kuiper et al, 2006). Make a histogram that shows the distribution of diameters. Most of these craters were formed during the first billion years of the Moon's formation, but you should confirm that this is true for the the Moon areas you've selected in your photographs by doing background research. Is cratering uniform… Read more
