Engineering Design Process
In this engineering challenge, you will use limited materials to build a paper tower as tall as possible, but there's a twist! Your tower must also support a heavy weight at the top without collapsing. Looking for inspiration? You can see how other students have tackled this and other annual Science Buddies Engineering Challenges. Teachers, lesson plan versions of this challenge are also available. 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 a parachute and an open rain jacket have in common? They both trap air and slow you down when you move fast! In this activity, you design a parachute for a miniature action figure. Tissue paper or a plastic bag and a few strings is all it takes to make your figure into an expert skydiver. Read more

Do you like arts and crafts projects like drawing, painting, cutting shapes out of construction paper, or origami? Instead of drawing that bright sun or lights in a house, imagine adding real lights to your artwork! This project will show you how, by introducing you to the world of electronics with "paper circuits." Paper circuits are made with just a few simple items; you can use a battery and some copper tape to add tiny lights to your project. The best part is that it is easy to do, and you… Read more

Have you ever seen the Diet Coke® and Mentos® experiment, which is all over the Internet, and wondered what makes the reaction work? You might think that there is some ingredient in a Mentos candy causing a chemical reaction with the soda, like the way baking soda reacts with vinegar. But the amazing eruption that takes place when Mentos are dropped into Diet Coke is not a chemical reaction at all! Instead it is a physical reaction. That means that all of the pieces of the reaction… Read more
