Science Fair Project Idea

You can model this with an ice cube sliding down a plank: how high do you need to lift the end of the plank before the ice cube starts to slide? Try this with one side plain wood and the flip side waxed wood (use paraffin wax, candle wax or ski wax). Make sure both sides are equally smooth to start with. Do at least three trials. More advanced: using what you know about the forces acting on the ice cube, derive equations to calculate the coefficient of friction for each case. Variation:…

How does ski wax affect the sliding friction of skis? You can model this with an ice cube sliding down a plank: how high do you need to lift the end of the plank before the ice cube starts to slide?

Science Fair Project Idea

Many sports skills require quick reaction times: think of hitting a 95mph fastball, returning a 100mph tennis serve, or blocking a slapshot at the net in hockey. (The Experimental Procedure section below has one way to measure reaction time.) Is your right hand faster than your left? Can you improve your reaction time with practice? Do both hands improve if you only practice with one hand? Try relating your reaction time to real situations in your favorite sport. For example, calculate…

Science Fair Project Idea

Can an authority figure make someone question their own memory? How reliable is eyewitness information? This project looks into these questions. You'll need a postersized image that includes many faces, and a volunteers to act as "eyewitnesses." The volunteers are tested individually. The instructions are that they have one minute to examine the poster, and then a fixed amount of time (e.g., 5 minutes) to write down brief, accurate descriptions of all the faces they can remember. They'll…

Science Fair Project Idea

For example, think of hitting a baseball, heading a soccer ball into the net, or hitting a tennis ball with a racquet. Where the ball goes depends on...what? You can set up a simple model to start your investigation. You'll need a marble, a flat piece of wood, a flat piece of cardboard, a pencil, a ruler, a protractor, and a level surface. Lay down the cardboard down on a level surface and set up the flat piece of wood at one edge. The wood will act like a wall, and you're going to roll…

Science Fair Project Idea

If you have a multispeed bike, you know that you can make it easier or harder to pedal just by shifting gears. Ever wonder how that works? You can investigate this a number of ways. A basic approach is to use a selection of spools of thread (with different diameters), a board with two nails, and a rubber band. Place a spool over each nail, and put the rubber band over them. Mark the 12:00 position on each spool so that you can count revolutions. Turn one spool through a full circle and…

Science Fair Project Idea

How high can you throw different types of balls, like a golf ball, a basketball, and a football? Would one of them go higher than the others? Do factors like mass, shape, and volume influence the final height? You can measure the approximate maximum height a thrown ball reaches by measuring the time it spends in the air.
To do this project, you'll need at least one ball and a helper with a stopwatch. Your helper should start timing just as you release the ball, and stop right when the ball…

Science Fair Project Idea

This project can apply to soccer, hockey, baseball and many other sports. What is the effect of stopping the kick/shot/swing at the moment of impact vs. following through? Think of a way to measure the outcome in each case, and explain your results. (idea from Gardner, 2000, 8385; for more information with regard to specific sports, see: Barr, 1990, 1214; Gay, 2004, 142144; Adair, 2002, 30.)

Science Fair Project Idea

Take shots at a set distance from the basket, but systematically vary the angle to the backboard. For a basic project: How do you think your success rate will vary with angle? Draw a conclusion from your experimental results. A bar graph showing success rate at different angles can help to illustrate your conclusion. For a more advanced project: Use your knowledge of geometry and basketball to come up with a mathematical expression to predict your success rate as a function of angle…
