Water is a valuable resource, and water shortages are a serious problem in many parts of the world. The problem can be made worse by people who waste water; for example, by watering a garden or using sprinklers on their lawn (or a farmer taking care of an entire field) when it has rained recently or the soil is already moist. How can you help conserve water and prevent such waste? One way is to build an electronic soil moisture sensor. This project will show you how to build a circuit that… Read more

The enormous task of cleaning up oil spills in oceans and seas has burdened industry, government, and environmentalists for decades. The cleanup is almost always difficult. It involves great amounts of time, resources, and money to remove the oil from the water, and the cleanup is often only partially successful. Today, however, scientists are coming to the rescue, developing a new technique that combines nanotechnology and magnetism. In this science project, you will test the proposed… Read more

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. Check out the video to see what this simple, but fun, project looks like. Once you have the basics down, you can keep tinkering with the circuit, the sounds, and the program to make fancier versions of… Read more

Engineers are trying to tackle the world's ocean pollution problem using robots. Some robots, like Mr. Trash Wheel and the ship featured in this Mark Rober video, are stationary and collect trash as it flows out of rivers before it gets into the ocean. Others, like the Jellyfishbot, are mobile and can squeeze into narrower spaces to collect trash: Can you build and test your own trash-skimming robot? If you do not have access to a natural body of water to test it in, you can use a bathtub or a… Read more

Have you ever wished you could create an alarm system to guard your stuff? Or what about throwing a surprise party for someone and automatically playing music and flashing lights when they walk in the door? You can do either of these things using a Raspberry Pi. The kit includes a motion sensor, which can detect when people move in front of it. Check out the video to see what this simple, but fun, project looks like. Read more

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. Check out the video to see what this simple, but fun, project looks like. Read more

Have you ever seen night lights that automatically turn on when it gets dark? What about art projects, like paintings or sculptures, with embedded lights? This project will let you combine the two, by adding lights to an art project of your choice. You can make the lights automatically turn on when it gets dark using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. Read more

Drones are small, fast, and maneuverable - this can make them very hard to knock down! Check out this Mark Rober video where he explores both how professional defense companies and some backyard YouTube engineers tackle the problem of knocking drones out of the sky. Can you take this engineering challenge on yourself? What methods can you devise to take down a drone? Which one works the best?  Drones can be expensive, and you probably do not want to risk damaging a $1,000 drone for your science… Read more

Did you ever have a favorite toy like an action figure or doll that could light up, make noise, or move? This project will show you how to make your own interactive toy using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. The version you make does not have to be a robot; it can be any shape and have any sound effects you want. Read more

Have you ever had to take prescription medicine to get over an illness? To get better, it is important to take the medication in the proper manner and at the proper time. Wouldn't it be cool if there were a tool or piece of automated equipment that held your medicine and reminded you to take it? A tool that would know when you picked up the bottle and took your medicine? Building a smart medicine cabinet is what this science project is all about! Read more
