How lovely it is to come home after a chilly winter walk to a cozy house, put on your fluffy slippers, and settle by the fireplace with a warming cup of hot chocolate. Animals like the polar bear, the Arctic wolf, or Antarctic penguins are not so lucky to have such a place. How do they face the extreme winter temperatures? Most take on “winter coats” in the fall. Wondering what these coats look like, and how they help keep animals warm? Do this cool activity and you will feel it… Read more

How long do you think you could survive without drinking any water? Only three to four days! Your body needs water to function properly. We also rely on water for cooking, cleaning and many other activities. You might not think about getting enough water if you can get it easily by turning on your faucet. But what about areas that don't have a reliable water supply? In this activity you will learn about one creative way to collect water—from the air! Read more

Have you ever been zapped by a door knob or another person? It feels like a little electric shock and usually happens on cold and dry winter days. Where is this shock coming from? Why is it that sometimes you get zapped and sometimes you don't? It all has to do with static electricity, which can build up in some materials and then be transferred from one object to another. Sometimes you can even see a spark fly between them! In this science activity you will explore how well materials around… 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

If you've ever been shot with a rubber band then you know it has energy in it—enough energy to smack you in the arm and cause a sting! But have you ever wondered what the relationship is between a stretched rubber band at rest and the energy it holds? The energy the rubber band has stored is related to the distance the rubber band will fly after being released. So can you guess one way to test how much energy a stretched rubber band contains?

Have you ever wondered why rubbing a balloon or a blanket—or even a winter hat—on your head makes your hair stand up? The effect is due to static electricity, but how is the static electricity made, and why does it make your hair stand on end? Static electricity is the buildup of electrical charge in an object. Sometimes static electricity can suddenly discharge, such as when a bolt of lightning flashes through the sky. Other times, static electricity can cause objects to cling… Read more

Light is fascinating! It can look like a wave or a particle; it can be red, blue or any color of the rainbow; you can even mix all the colors together to get white!  It travels in straight lines and still appears to bend around objects. It can travel through air, but it does not need the air. Unlike sound, light can travel from distant stars through a vacuum and reach us years later, or it can be sent through fiber optic cables and go around the world in less than a second! Does that sound… Read more

Is Thanksgiving one of your favorite holidays of the year? All your friends and family are getting together to celebrate. The table is full of delicious food—a big feast—and there might even be some fancy China and glassware on the table to make the celebration even more special. Who can resist the temptation to make the wine glasses sing? You have probably done this many times before, but have you ever wondered, why the wine glass makes this sound? Do this activity, and you will… Read more

Are you ready to bend light, magnify letters, and have fun with drops of water—all while getting a glimpse into how lenses work? Lenses are the key components in eyeglasses, contact lenses, binoculars, telescopes, and magnifying glasses, just to name a few devices. With this activity, a homemade magnifying glass is only a drop away! Read more

If you pour water into a clear glass, what color is it? It’s clear, right? But what happens if you try to look through it to see the world on the other side of the glass? It looks a little distorted, maybe a little fuzzier and uneven. If water is clear, why can’t we see through it clearly? The answer has to do with how light moves through water, glass, and other transparent materials. Just like when you try to run in a swimming pool, when light tries to move through water or glass,… Read more

Do you love playing on a seesaw? Why is it that depending on where you sit on the beam, and the weight of the person on the other side, you either fly up into the air or fall down to the ground? And why is it so difficult to perfectly balance the seesaw? It can all be explained with physics! In this activity, you will investigate the balancing forces of a seesaw—with a seesaw made of candles! Read more
