Did you know that there are about 10,000 different types of birds in the world? You don't have to go far to see some of them. Birds live outside in backyards and parks and can even be found in a busy city! Do you know what kinds of birds live in your neighborhood? Have you ever taken a close look at the birds you see in your backyard to identify them and observe their behavior? In this activity, you will build a bird feeder to attract birds, so you can study them. 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 why your phone, computer, or a flashlight works without being plugged into a power outlet? Where does the electrical energy come from that makes all these portable devices function? You probably know the answer: they use batteries! But do you know how these batteries work? Batteries store electrical energy in the form of chemical energy, which means that electrochemical reactions inside the batteries create electricity. It may sound complicated, but it is simpler than you… Read more

Have you ever dropped your phone in the water and it stopped working? It would be great if you could somehow dry the phone from the inside before it got damaged, right? There are actually some substances that can absorb water from their surroundings. You might have noticed that when you buy new shoes, electronics or beef jerky, that often there is a little package inside that says “silica gel, do not eat.” This little bag of silica gel protects the product from water damage when it… 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

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
