"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!
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.
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!
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?
Have you ever tried to pull out a nail out of wood with your bare hands? Or have you tried to shove a staple through a stack of papers without a stapler? A hammer's claw, a stapler, a pair of pliers and a shovel are each examples of everyday tools that use levers to make our work easier.
Are you artistic? Do you enjoy creating art? Some may think that art is something only humans can make, but what about robots: can they be artistic? They can if you build them that way. In this robotics engineering project, you will build a robot that creates art. And who knows? Someday your robot art may be worth millions!

This robotics engineering project requires you to purchase VEX® robotics materials. See the Materials and Equipment list for details. With a little problem-solving, you may be able to substitute another robotics platform.
Very High (over $150)
Use caution with tools when assembling the robot. Minor injury is possible.
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…
Today magnetic recording is used in audio and video cassette recorders, and computer disk drives. Did you know that you can also use an electromagnet to record and play back from a steel wire? In fact, this is how magnetic recording got started. This project shows you how to build a simple wire recorder.
Music boxes, bicycles, and clocks all have one thing in common: GEARS! You might say that gears make the world turn, since they are in so many mechanical instruments. How do they work and how do you know which gears to use? Find out in this simple experiment.
Want to know how electrical engineers "trap" the energy in a circuit to make your favorite electrical appliance? Video games, computers, phones, and many other electrical devices use "resistors" in different ways to control the electricity in a circuit. In this experiment, you can make your own resistors out of pencils, and test the effect a resistor has on a circuit.
