The egg-drop project is a classic and time-honored tradition in many science classes. The goal is usually to build a device that can protect an egg when dropped from a high location. This activity puts a twist on the classic project, motivated by real-world advances in space exploration. Can you build a reusable egg-drop lander that can survive repeated falls from the same height? Try this activity and find out 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

Did you know that there are more planets than stars in our galaxy? All of these planets circle around a star, but only eight of them—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune—circle around the Sun—the star in our solar system. This activity explores the relative size of these eight planets. Is one bigger than the others, or are they all about the same size? Read more

Have you ever wondered how crystals are made? Crystals come in all different shapes and sizes. However, the purest and cleanest crystals are usually also the ones that grow to be the largest in size. In this activity, you will compare the size and shape of crystals grown at different temperatures. With just water and Borax, a household cleaning product, you can discover the method for growing large, pure crystals! Read more

What if you could take a single liquid, and change it into a rainbow of colors without using food dye. You can! In this activity you will use red cabbage to make what is called an indicator solution. Indicator solutions can change colors depending on what you add to them. In this case adding something acidic (like lemon juice) will change it to one color while adding something basic (like bleach) will change it to another. Try and see how many colors you can make using different household… Read more

Do you think plants can grow without soil? If you've tried growing vegetables, you probably planted the seeds or seedlings in soil. Soil gives the plants the nutrients they need to grow. However, plants can grow without soil, too, using a process called hydroponics. In this activity, you will transform a bottle into a mini-garden that needs only light, air, and nutrient-rich water to grow! Read more

If you have ever watched a rocket launch on TV, you might have noticed that rockets have multiple stages. Some parts of the rocket fall off and burn up in the atmosphere whereas the rest of the rocket keeps going. Why does this happen? Try this activity to find out and build your own two-stage rocket using balloons! Read more

Have you ever wondered why leaves change from green to an amazing array of yellow, orange, and red during the fall? Leaves get their brilliant colors from pigments made up of various color-creating molecules. During the warm, sunny months, plants use their leaves to turn sunlight into food energy, a process called photosynthesis. This primarily uses a pigment that reflects green light, which gives the leaves their characteristic color. In autumn, when colder, shorter days arrive, many kinds of… Read more
