Build a Simple Machine Science Projects (6 results)

Build a simple machine, such as an inclined plane (a board on a slope), a lever, a pulley, or a wheel and an axle. Investigate how to make changes to your machine to increase force, speed, or distance traveled.

Science Fair Project Idea
Do you think you could build a car powered by nothing but air? A balloon-powered car is pushed forward by air escaping from a balloon, and it is fun and easy to build with materials you already have around your house. Can you imagine how you would want your own balloon-powered car to look? Can you design a car that will travel as far as possible? You can even measure your car's speed using your smartphone and Google's Science Journal app. Get ready to grab some simple supplies to bring your… Read more

Did you know that you can lift an object that's heavier than you are? Just use a lever! In this science project you'll build a tabletop lever and measure how much effort it takes to lift an object using it. Read more

Do you like winter sports like sledding or skiing? Check out this winter-themed engineering project to build your own miniature "ski lift." Use it to transport small objects from one place to another, just like a real ski lift transports skiers from the bottom of a mountain to the top. Read more
Science Fair Project Idea
Have you ever dropped something and wondered how fast it was moving while falling? If it was something fragile, like a cell phone, you might not have been thinking about this at the time — you may have been too busy trying to grab the phone! But you probably wanted to find out just how hard it hit the ground afterwards. We know that gravity forces an object to fall, but how does this affect how quickly something falls and how hard it hits the ground? For example, did the phone move faster… Read more

Before the Industrial Age, people relied on muscle power for moving and lifting heavy objects. Here's a project that shows you how you can use your head to make heavy lifting easier on your muscles–and your back! Read more
Science Fair Project Idea
This project is an experiment in classical physics. You'll be following in Galileo's footsteps, and investigating Newton's laws of motion, but you'll be taking advantage of modern video recording technology to make your measurements. Sure, it's been done before, but if you do it yourself, you can get a firm understanding of these important concepts. Read more
