Have you ever wondered what the world would look like without colors? Most of us take them for granted since they are everywhere: blue sky, green grass, the yellow sun, and countless more. Your eyes are actually able to distinguish up to 10 million colors! But where do all the colors come from, and how do our eyes perceive them all? Find out with a little help from some shadows, and create numerous colors by mixing red, green and blue light. Read more

Did you know that you can change the genetic code of an organism? This technology is called gene editing or genetic engineering. Using gene editing tools, researchers can delete or modify existing genes in an organism, or even add new ones! With this ability, they can alter the way an organism—such as a bacteria, a plant, or an animal—looks or functions. For example, crops can be modified to become more drought-resistant, or bacteria can be engineered to produce medicine such as… Read more

Have you ever opened a fresh bottle of carbonated water or soda, poured a glass of it, and just watched as the bubbles fizzed upward in the glass? Have you ever wondered what those bubbles are? They're made of carbon dioxide gas, which was packed tight in the soda before you opened the bottle. Not only can that carbon dioxide gas give you a fizzy drink to enjoy, but it can also give you a show. How? By making candy conversation hearts "dance!" Along the way you will discover some of the fun… 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

Why buy it when you can build it? That is the attitude you will need for this project. You have probably seen cell phone holders or stands around the house or in a car. They might seem like a very simple object, but they are a great way to learn about the engineering design process. In this project, you will design and build your own working phone stand. Read more

How do you steer a drone using a controller with a joystick? Find out in this activity as you program an Arduino to interface with an analog joystick, similar to those found in most video game controllers. You can use the joystick to make a mini popsicle stick drone tilt side to side or move up and down. See this page for a complete list of our mini drone projects. You may wish to do the projects in order. Read more

Have you ever wished you could copy a drawing but make it larger or smaller? If you've tried to create a larger or smaller copy of your work, you've probably realized that it is very hard to get the details right. A machine called a pantograph, however, could help. It makes copies that can be scaled up or down or made the same size. In this activity you will make your own pantograph and then duplicate your drawings. Can you figure out how it enlarges, shrinks or turns drawings upside down? Read more

Have you ever dyed eggs? Turning eggshells from white into different, dazzling colors can be a lot of fun! People often do this using dye tablets to make different colors in a liquid bath. They then dip the egg into the liquid and wait till it turns the desired color. Eggs can be dyed in many other ways, and one neat method uses silk ties. Sounds strange to use clothing to dye eggs, right? But it actually works really well! In this activity, you will dye eggs with silk ties and… Read more
