"Swing me higher, Mommy, higher!" Kids love to ride the swings at the playground. The back-and-forth motion of a swing demonstrates the physics of a pendulum. In this experiment, you will investigate the factors that affect the speed and duration of a pendulum's swing, also called an oscillating motion. You can even use your phone and a sensor app to record your pendulum's movement and determine its period of oscillation.

Hooke's law says that the opposing force of a spring is directly proportional to the amount by which the spring is stretched. How accurately Hooke's law describe the behavior of real springs? Can springs be used to make accurate scales for weighing objects? Spring into action and find out for yourself with this project.

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…

How do you feel when you ride your bike into a strong wind? Do your legs feel like lead? How about when the wind is at your back? Does that make you feel ready for the Tour de France? In this science fair project, you will investigate how wind-powered devices, like pinwheels, also react in different ways to the direction of the wind.

Want to do a project with a toy your parents, or even grandparents, might have played with? Slinkies are fun toys that also make great physics and engineering projects. In this science project you will investigate how changing the angle of an inclined plane affects how the Slinky walks down it. What angle will enable the Slinky to go for the best walk?

Alka-Seltzer® tablets fizzle furiously when dropped into water. The moment the tablet starts dissolving, a chemical reaction occurs that releases carbon dioxide gas. In this science project, you can even measure how long and loudly your tablet fizzes using a smartphone equipped with a sensor app. Do you think you can make Alka-Seltzer fizz faster or more loudly by changing the temperature of the water? How big of a difference in the rate of a chemical reaction can temperature make?

The renowned pianist Vladimir Horowitz once said, "The most important thing is to transform the piano from a percussive instrument into a singing instrument." In this project, you will learn how you can make piano strings sing using sympathetic vibrations. Find out which notes make another one sing the longest by measuring their sound intensities using a smartphone equipped with a sensor app.

This is a great project for a musician who is interested in the physics of stringed instruments. If you've ever played an acoustic guitar, you may have noticed that picking a single string can make one or more of the other (unpicked) strings vibrate. When this happens, it's called sympathetic vibration. What intervals lead to the strongest sympathetic vibrations? Find out for yourself with this project.
