thumbnail In our , you were challenged to use the VoxCAD software to design the fastest possible robot using different materials. However, we did not ask you to think about one big thing — efficiency. It is great to design a robot that is very fast, but what if it also consumes a lot of energy? Engineers must consider this when designing robots in the real world — robots that use more energy to move will drain their batteries faster, which can be a problem. This is similar to the concept of… Read more

thumbnail Watching professional racing-car drivers compete can be thrilling. The high speeds that racing cars can reach — up to 200 miles per hour (mph) and more! — put some unique demands on the vehicles. For example, to withstand high temperatures, the tires must be inflated with nitrogen gas, instead of air as with normal car tires. This enables the drivers to have better control over steering their cars as they race around the track. In this sports science project, you will inflate… Read more

Science Fair Project Idea
thumbnail Have you ever heard of the NASA Mars rovers Spirit, Opportunity, and Curiosity? How about the "bomb squad" robots that police and the military use? These are places that are hard for us to reach (Mars), or dangerous for us to be near (explosives). Because the human operators are usually far away from the robot, driving one is different from driving a car. Operators rely on information sent back from the robot, including pictures and video. In this project, you will build your own simple… Read more

Science Fair Project Idea
thumbnail Mowing the lawn is hard work, especially on a warm day. Not only do you have to mow the grass, but you also have to dispose of the clippings. Some people add the clippings to a compost pile in their yard, which is a great idea. But did you know that some grasses can be used as a source of energy? In this energy science fair project, you will learn more about a type of energy called biomass energy. You will grow different kinds of grasses and see which type of grass gives you the most biomass,… Read more

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
thumbnail If you ride a bike, you probably know that you have to occasionally pump up the tires to keep them fully inflated. Over a long period of time, the tires slowly leak air, so their pressure will decrease. Have you ever noticed that it is actually harder to ride a bike when the tire pressure is too low? This is because the tires are a big factor in the rolling resistance of the bike. In this sports science project, you will measure how tire pressure affects the force required to move a bike. How… Read more

Have you ever tried rubbing your stomach and patting your head at the same time? What about doing your homework or studying for your math test while watching television? It is tough to focus on a task when you are distracted doing something else, isn't it? In this science fair project, you will investigate how distractions affect your focus on a task, such as driving, by looking at how gaming scores are affected as you're talking on a cell phone or having a conversation with a friend.

thumbnail Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process. Read more
