Have you ever been annoyed by poor Wi-Fi reception for your phone, tablet, or laptop? Do you wish there was something you could do about it? In this project you will learn how to build a parabolic reflector that you can attach to the antenna of a regular wireless router to help boost its signal.
Every day, no matter where you are, you will see people using their cell phones. People use their cell phones for
more than just making calls though. They use them for texting and searching the Internet, too. But some health groups
are concerned that using your cell phone too much can be hazardous to your health as it exposes your body to electromagnetic radiation. In this electricity and electronics
science project, you will investigate how much radiation your cell phone emits when used…
What do the radio, TV, radio controlled cars, and cell phones all have in common? They all use invisible waves to transmit information. Find out which materials block radio waves, and which materials allow radio waves to pass through by doing this experiment.
Have you ever wondered how an AM radio station works? In this project you will learn the basics of how your favorite songs are transmitted by a radio station, by building your own simple AM radio transmitter. You will learn the basics of how a transmitter works, and how you are able to tune to your favorite station and listen to music.
You might think that one sure-fire way to keep your computer safe from hackers is to disconnect it from the internet entirely. But did you know that even without internet, a computer can transmit data using light, sound, vibrations, or even heat? In this project, you will investigate how a spy or hacker can steal data from an "air-gapped" computer that has no internet connection. You can even use a smartphone equipped with a sensor app to demonstrate how the data can be picked up by a nearby…
Have you ever wondered what it would be like to have an extra sense? What if you could hear above the normal range (ultrasound) like dogs or bats? What if you could see ultraviolet light, like bees or juvenile trout? What if you could see infrared light, like a rattlesnake or boa constrictor? This project shows you how you can use a phone or camera, tripod, and a special filter to take pictures using near infrared illumination. It's a whole new way of looking at the world.
Radio-controlled (RC) robots can explore places that are difficult or dangerous for humans to get to, like collapsed buildings after a natural disaster. They can use cameras and a variety of other sensors to gather information about their environment, like the presence of toxic gases or other hazardous materials. The robots can even use grippers and robotic arms to collect and safely dispose of some materials. You can build your own RC robot using the Science Buddies Bluebot kit, Science…
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.

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:
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.
