Balloons are fun and come in a variety of sizes, colors, and forms that makes them well suited for decorations, water play, modeling, and other creative activities. But balloons also have uses outside of recreation; weather balloons, balloons used to widen obstructed arteries, and balloons that provide transportation are just a few examples. The first balloons were made of animal bladders or intestines. This made way for the latex, rubber, and nylon fabric balloons we see today. Have you ever… Read more

How do driverless cars know how to recognize different road signs? They use something called machine learning. In this activity you will teach a computer to recognize different road signs using photos that you take yourself and a tool called Teachable Machine by Google®. The better the training data, the more accurately the program will be able to recognize different types of signs. Read more

Are you good at tossing a Frisbee? Have you ever wondered how a Frisbee is able to fly through the air so well? If you can throw a perfect, arcing curve, right on target, you have already trained your arm on the aerodynamics of Frisbee flight! In this science activity, you will investigate how the angle at which you throw the Frisbee affects its flight's direction and distance. Next time you are out tossing a Frisbee, this little lesson in aerodynamics may help make your throws be even… Read more

Did you know that the seaweed you've seen in the ocean or even eaten as a snack is inspiring innovators to imagine new materials? Large brown algae, like kelp, contains polymers—long chains of molecules—that are more environmentally friendly than the ones in most plastics. These natural polymers (alginates) could eventually be used to create sustainable everyday objects. Try your hand at using a bit of chemistry to turn biodegradable polymers from algae into your own custom… Read more

Have you ever wondered what keeps you in your seat when you are riding a giant loop-de-loop roller coaster? Surprisingly, it is not the seat belt! You are kept in your seat because of something called centripetal force. Centripetal force actually does much more than make a ride on a roller coaster's loop possible — it keeps a satellite in orbit and you in your bicycle when taking a tight curve! In this science activity, you will use marbles and Jell-O® to investigate centripetal… Read more

Water is one of the most important resources for life. Here on Earth, we often take it for granted — we can easily get a glass of water from the tap whenever we’re thirsty. But imagine being an astronaut orbiting hundreds of miles above our planet. In space, every drop of water is precious, and there’s no tap to turn on. Transporting water from Earth to the ISS is incredibly expensive and impractical due to the limited cargo space and the high cost of launching supplies. To address this,… Read more

Sensors are everywhere—on your phone, in your car, and even at the grocery store. Learn how to craft your own wearable sensor that you can put on your clothing. Using a simple and easy crafting method, you will be able to weave your own capacitive touch sensor patch that will detect when someone touches the fabric. You can use the sensor to turn on an LED, buzzer, or motor when it detects touch! Read more

Have you ever heard anyone say the chance of something happening is "50-50"? What does that actually mean? This phrase has something to do with probability. Probability tells you how likely it is that an event will occur. This means that for certain events you can actually calculate how likely it is that they will happen. In this activity, you will do these calculations and then test if your calculations hold true for reality! Read more
