Put Your Peripheral Vision to the Test

Did you know we use our side vision for many daily activities, like riding a bike, reading or playing basketball? Few people realize they are even using it. Our survival once depended on the quick response of our peripheral vision. A detailed picture, created by our central vision, is only useful in situations where time allows us to focus on the details. But our side vision can help us avoid dangers quickly. In this activity, you will find out how specialized our peripheral, or side vision, is. Read more

Have you ever been on a swing set and suddenly noticed that the person on the swing next to you seems to be swinging almost exactly in time with you? You go up and down at either the same time, or exactly opposite each other. This might seem random – but it’s actually physics! Like many things in nature, swing sets have a ‘resonant frequency’, which means that they have a ‘favorite’ frequency (or speed) of movement. The swing set will naturally want to swing… Read more

Do you have a favorite Thanksgiving dinner dish? Maybe it’s an aunt’s special cranberry sauce, or mashed potatoes combined with perfectly-seasoned gravy. Or perhaps you enjoy sinking your teeth into a succulent roasted turkey the most. Dinner rolls, biscuits, corn breads, muffins, pastries and pies may also be baked for this special meal; the foods in this group typically all contain a substance called gluten. In this science activity, you’ll explore why some foods, all made… 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
Seawater Science: Model Ocean Currents in Your Kitchen
STEM Activity
Have you ever wondered what causes ocean currents? Ocean currents have profound effects on the climates of the continents, especially those regions bordering on the ocean. For example, it’s thought that the Gulf Stream (a warm current around the North Atlantic Ocean) makes northwest Europe much warmer than it would otherwise likely be. In this science activity, you will model the behavior of these “rivers” of hot and cold water within the ocean to find out how temperature… Read more

Have you ever tried to pat your head with one hand while you rub your stomach with the other? This science activity is kind of like doing that, but it can actually give you some insight into how your mind works. The challenge of this activity is to name colors. It sounds simple enough, right? If you think it does, you should see what happens when words of colors get in the way! This is a fun activity to try out with family and/or friends while spending time together over the holidays.

You probably know that some liquids, such as oil and water, do not mix together. If you pour them into the same container, they will form two separate liquid layers on top of each other. Other liquids, for example rubbing alcohol and water, can be mixed with each other. But did you know that once both of these liquids have mixed, you can separate them again into two different layers? How can you do that? The answer might surprise you: with salt! In this activity, you will find out how this… Read more

Have you ever had fun making different figures or colorful creations using some Play-Doh? You can squish and stretch a single piece of Play-Doh to make all sorts of shapes. How does changing the shape of a piece of Play-Doh affect its volume? In this science activity, you will find out by investigating how a piece of dough’s shape affects its dimensions (length, width and height), and how these changes are related to the dough’s volume.  Read more

You’re watching an action movie, and suddenly the hero dives through a glass window! Or a car window shatters as the hero navigates an exciting car chase! The glass looks so real, but believe it or not, Hollywood movie sets rarely use real glass for those scenes. Can you guess what they use instead? If you guessed candy…you’re right! Instead of using real glass, which is expensive and difficult to replace for multiple shots, Hollywood movie sets use Sugar Glass! This cheap,… Read more

Have you ever wondered how fast a heavy object falls compared to a lighter one?  Imagine if you dropped both of them at the same time.  Which would hit the ground first?  Would it be the heavier one because it weighs more?  Or would they hit the ground at the same time?  In the late 1500s C.E. in Italy, Galileo was actually asking some of these same questions and did some tests to answer them.  In this activity, you’ll do some of your own tests to determine… Read more
