Try the annual Engineering Challenge from Science Buddies! Open to all students worldwide, a new challenge and prizes are announced every January. Explore the current challenge as well as ones from past years!
Have you ever suffered from poor Wi-Fi reception for your smartphone, tablet, or laptop? Certain materials can actually block a Wi-Fi signal; do you think that could be part of your problem? In this science project, you will do an experiment to find out which materials cause the biggest drop in signal strength from a wireless router.

In this engineering challenge, you will build a car powered by nothing but a rubber band. The farther the car goes, and the fewer materials you use to build it, the higher your score. Enter your score in the 2024 Science Buddies Engineering Challenge for a chance to win prizes! Teachers, lesson plan versions of this challenge are also available.
Lights and music make a great combination! Getting sound and lights to complement each other just right helps set the mood for everything from DJ parties and concerts, to theater shows, the circus, and ballet performances. You can put together your own lights and music show using
a Raspberry Pi.

Once you have the basics down, you can keep tinkering with the circuit, the sounds, and the program to make fancier…

Does your home have any pet doors or gates for dogs, cats, or other animals? Some automatic pet doors can be set up to allow only certain animals through. These doors can help you control which pets are able to go outside alone or which ones have access to specific food, litter boxes, or toys. But why buy such a door when you can make one? In this project you will build your own automatic pet door that works with a magnetic collar tag. Exactly how you use it is up to you!
Did you know that you can tell how much information is on a CD-R without even using a computer? Find out how in this "reflective" experiment.
Have you ever played a game that tested the steadiness of your hands? Operation® is a popular board game that requires you to perform "surgery" without bumping a tool against the edges of the game. There are also popular amusement park or carnival games where you try to move a metal loop along a wavy metal wire without letting the two touch. You can build your own version of these games using
a Raspberry Pi.

When you delete a file, by accident or on purpose, is the information really gone? Can you get it back? If you accidentally deleted your five-page report for school, you are hoping it is not gone. On the other hand, if you do not want someone to get their hands on the goofy and unflattering pictures you and your best friend took while staying up late the other night, you probably hope it is gone for good! It might be nice to know for sure either way. Try this project to find out.
When you were little, did you ever make "music" in your kitchen by banging kitchen utensils on pots and pans? What if you could actually take those kitchen implements now, and play them with different sound effects? In this project, you can convert basic kitchen utensils into your own electronic drum set using
a Raspberry Pi.

How fast are computers? How quickly do you think they can do 100 million arithmetic problems? Try this science project to discover an easy way to measure how fast computers have become and whether or not your computer is a math whiz.
Important: this project was originally written in the mid-2000's, and computers have gotten a lot faster since then! The project will probably not work as intended if you run the code on a modern computer.
Have you ever played a computer game in which a cartoon character, like a dog or a cat, moves or turns when you click on it? Have you ever wondered how characters know how far to move or how far to turn? In this computer science project, you will learn how with a simple (and free) program called Scratch, which will let you write your own computer program that tells a cartoon kitty how to draw shapes.
Do your parents ever get upset with you for "wasting" paper and ink from your printer? Maybe you wanted to print a comic you found online, or a whole bunch of pictures of you and your friends being goofy, or all the instructions on how to put together that really awesome LEGO® castle. But 20 pages of text and pictures later, your mom or dad is yelling at you. Why do they even care how much you print? And why do people say it is a "waste" of paper? Try this printer-saving science project to…

Do you or your parents ever use the Internet to get fast answers to all types of questions? Like what time does the amusement park open? How do you open a lemonade stand? When is the next Pixar movie coming out? Chances are, any question you can think to ask is answered somewhere on the Internet. But getting to the right answer can be hard! If you've ever used Google (or any other search engine) to try to answer a question, you've probably gotten back pages of results, none of which had the…
