Take a deep breath: freshly baked cookies, smoke from a wood fire, or a bouquet of roses—your nose is an amazing smell detector! Your sense of smell can not only identify a huge variety of odors, but it is also incredibly sensitive. Think about how easily you can detect if someone in your neighborhood has a barbecue just by smelling hints of smoke from a faraway grill. But how good is your nose when it comes to differentiating individual smells? Do this activity to find out! … Read more

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

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 someone tells you to remember a phone number or address, it can feel like an easy task at first. You repeat the numbers to yourself, either aloud or in your mind. But after just a few seconds, you may find yourself starting to doubt your own memory. Was it 5-7 or 7-5? Our minds are always seeking new and useful information, and as a result, it will try to ‘throw away’ information that seems old or irrelevant, such as a random string of numbers or an address. However, there are… Read more

Do you like your hair shiny and beautiful? The key to keeping your hair nice and clean is to use a good shampoo. But what exactly makes a good shampoo? You might be surprised to hear that every new shampoo has to pass lots of scientific tests before it is considered good enough to be sold. Many different shampoo recipes are compared to decide which one is the best for the consumer. One of these tests assesses the foaming behavior of the shampoo. You probably trust a shampoo that makes lots of… Read more
