Does a Cell Phone Conversation Affect Reaction Time?

Science Fair Project Idea

Scientific Method

Does talking on a cell phone make one a more dangerous driver? Here is an experiment you can do to investigate whether reaction time is adversely affected by a simultaneous phone conversation. Read more

Do-Re-Mi with Straws

Science Fair Project Idea

Scientific Method

Do you love to make music, but do not have access to all the instruments you would love to play? Check out this fun science fair project about the physics of musical sound production. You will make musical instruments with drinking straws, one for each note on a one-octave major scale. Can you figure out the right lengths for a series of straw "oboes" in order to play a musical scale? Read more

Drawing Circles Around Ants

Science Fair Project Idea

Scientific Method

Do ants sometimes ruin your picnic? There are some chemical ant repellents you can spray to keep them away, but who wants to spray poison all over their food? In this science project you can investigate some less toxic solutions that may be around your home so that your next picnic will not become an ant buffet! Read more

How do you steer a drone using a controller with a joystick? Find out in this activity as you program an Arduino to interface with an analog joystick, similar to those found in most video game controllers. You can use the joystick to make a mini popsicle stick drone tilt side to side or move up and down. See this page for a complete list of our mini drone projects. You may wish to do the projects in order. 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

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

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

Electric Paint: Light Up Your Painting

Science Fair Project Idea

Scientific Method

Electric paint is a fun way to include a circuit with lights in an art project, but it presents a challenge not found in traditional electronic circuits. What happens if you change the length or width of your strokes of paint, such as by painting longer, curvier lines or using a thicker brush? Could this affect the electrical properties of your circuit? Try this project to find out! Read more
