Science Fair Project Idea
Do you ever wish you could hire someone to guard your favorite toys, or keep certain people from coming into your room? What if you could make a robot to do it for you? This project will show you how to build a simple security robot controlled by a motion-detecting sensor. When someone comes near your valuables or enters the room, the robot will spring to life and (hopefully) scare them away! Read more

Science Fair Project Idea
In the animal kingdom, many different critters use whiskers to help them find their way around in the dark, through murky waters, or even to help them hunt prey. Whiskers can be very useful when the animals cannot rely on sight. Did you know that you can also build a robot that uses "whiskers" to find its way around? This project will show you how to build a simple robot that uses whiskers as "bump sensors" to help the robot detect when it is about to bump into an obstacle, so it can turn… Read more

Science Fair Project Idea
Have you ever seen a cat chase a laser pointer or a flashlight beam? What if you could make a robot do that? In this project, you will build a robot that can automatically drive toward a bright light source. The robot uses a simple electronic circuit to track light, so there is no computer programming required! You can also do three other robotics projects using the same kit of parts, so this is a great way to get started with robotics before moving on to more advanced projects. Read more

Do you wash your hands? You should— it's the best way to prevent the spread of germs. But germs can be tricky; they find nooks and crannies to hide in, so it takes good hand-washing technique to get rid of them. In this science project, you'll investigate which parts of the hand are the most difficult to wash germs off of. Read more

"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

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
Flying kites is an excellent way to learn about aerodynamic forces. In this science fair project, you will build and test a variety of kite designs to see which flies best in low wind speeds. You will use an inexpensive anemometer to accurately measure the wind speed. Since you will be choosing which kites to build and test, the experimental procedure provides a general outline for the experiments, but there is a lot of opportunity for you to be creative with your kite designs. This is a DIY… Read more

Caves have been used for much more than just exploring throughout Earth's history. Caves have been used for shelter, for religious purposes, and for burial sites. They were even used for food storage, before refrigeration, because they are cool and have constant high humidity. But how are caves formed? What causes those fantastic formations in caves? How do cave formations change as you go deeper in the cave? Get ready for an adventure as you visit a local cave and learn more in this science… Read more
