Science Fair Project Idea
thumbnail Landslides are powerful geological events that happen suddenly, causing fear in people who live in areas with unstable hills, slopes, and cliff sides. Landslides damage the surrounding habitat and can destroy homes in their path. But what causes landslides? Can slides happen on any slope, or do slopes have to have certain characteristics, such as a steep angle and a specific material mass? In this geology science project, you will learn about the different types of landslides and the… Read more

This project is an experiment in classical physics. You'll be following in Galileo's footsteps, and investigating Newton's laws of motion, using a metronome as your timing device. Sure, it's been done before, but if you do it yourself, you can get a firm understanding of these important concepts. Read more

thumbnail 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. Read more

thumbnail "What?! Many of my toys are also machines?" That's right—simple machines! Simple machines are everywhere! Under your feet when you climb stairs, in your hand when you use a utensil to eat your dinner, even in your arm when you throw a ball. Come visit this science fair project and explore the six types of simple machines. Find out how many are hiding under the hinged lid (yes, another simple machine) of your toy box! Read more

Science Fair Project Idea
thumbnail Alka-Seltzer® tablets fizz furiously when dropped into water. The moment the tablet starts dissolving, a chemical reaction occurs that releases carbon dioxide gas. Can you make Alka-Seltzer fizz faster or slower by changing the temperature of the water? How big of a difference in the rate of a chemical reaction can temperature make? Read more

Science Fair Project Idea
thumbnail Have you ever played paintball with your friends? Wonder how you can improve your game? Paintball guns use compressed gas to shoot paint-filled pellets at high speed, and with good accuracy. The flight path of the ball is determined by its speed and the angle at which it is shot, relative to the ground. In this sports science fair project, you will explore the ballistics of paintballs, focusing on how drag and other factors affect the results. Read more

- Less Details
Time Required Average (6-10 days)
Prerequisites You should have access to a paintball gun, be familiar with how to shoot it safely, and have access to an open area where you can shoot it. This project has a fairly involved procedure, since you are measuring several parameters (velocity, time of flight, distance) and also comparing these measurements to what you would expect based on calculations. Feel free to customize the procedure based on your interests.
Material Availability Specialty items: You will need access to a paintball gun and accessories, including safety gear for you and for three helpers, as well as an instrument to measure velocity of the paintballs. See the Materials and Equipment list for details.
Cost Average ($50 - $100)
Safety Minor injury is possible, so wear eye protection. Adult supervision is required.
Science Fair Project Idea
thumbnail A tsunami is a series of waves made in a body of water, like the ocean, that can cause serious destruction when they hit the coastline. In deep water, a wave can be just a few feet high and travel very fast. As it nears the coastline, and moves into shallower water, tsunamis usually slow down, but the wave height can grow to 100 feet! In this ocean science project, you will model a tsunami and investigate how wave velocity (speed) depends on water depth. Does it match the mathematical equation… Read more

Safety Use caution when working with the lamp and the water tank. Make sure the two are far apart from each other at all times. Adult supervision required.
Science Fair Project Idea
Have you ever seen a skateboarder jump over an obstacle or slide down a railing? It looks like they are defying the laws of physics when they perform these tricks. It looks like it, but that's not the case. Physics describes the motion of objects and it is a skateboarder's best friend! All of these tricks can be explained by physics. In this sports science fair project, you will learn how speed affects "popping an ollie." The ollie is a basic skateboarding trick, and it's the first step to more… Read more

Time Required Short (2-5 days)
Prerequisites You, or someone you know, must already own a skateboard and safety gear, and know how to skate to perform the ollie trick. You must also have access to a video camera (it should include a timer if you decide to try one of the variations). You should perform the tests in a skateboard park or in a large area where it is legal and safe to skateboard.

Cost Very Low (under $20)
Safety Injury is possible. Adult supervision is required. The person performing the ollie must wear a safety helmet, elbow pads, and knee pads.

thumbnail Have you ever seen butterflies fluttering around outside, gliding through the air and landing on flowers? While they are delicate and fragile, butterflies are actually excellent flyers. They are so good, in fact, that scientists at Harvard University studied butterfly wing shapes as an inspiration for building a miniature flying robot. In this science project, you will do your own version of the Harvard scientists' experiment to measure the flight performance of butterfly wings. Read more
