Pop Science Quiz: What happens to water when it reaches 0°C (32°F)? Answer: It freezes! But does water always freeze when it reaches 0°C (32°F)? Believe it or not, water can sometimes be cooled to temperatures below its freezing point and still remain liquid. In this state the water is supercool. How can this happen? In this activity you will create your own supercool water, and initiate its transition from liquid to solid. All while making a tasty snack! Read more

How easy or difficult is it to build a gingerbread house? It depends on what you want your house to look like. Design possibilities are almost endless! You could make a multi-story building, try different shapes and sizes, or add extra features such as a balcony or chimney. The more complex your design gets, the more difficult it is to make sure that your house stays upright and keeps its shape. In this activity, you will become an engineer and design and build a gingerbread house that must… Read more

Do you ever wonder why we perform tasks in a particular way? Very often, we learn by copying someone and never stop to question if there is a more efficient or easier way to do something. This activity is about the tricky task of pouring from a full container. Could there be an easier way to do it? 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 tried making "walkie-talkies" using a long piece of string and two tin cans? If you have, you know that they work surprisingly well—at longer distances you can hear people better through the cans and string than you can through the air! In this activity we're going to use the same concepts to build a personal bell, one that makes sounds that only you can hear! Read more

Have you ever thought about where the vegetables you eat are coming from when it is too cold outside to grow them? They might have been shipped from a different country to your home town, or they may have been grown locally in a greenhouse. Greenhouses are huge house-like structures that are usually made mostly of glass. How can they protect plants from the cold? In this activity, you will find out and create some extra heat from the sun. Read more

Have you ever had to take antibiotics? Your doctor probably told you to finish taking all the pills even if you felt better after one or two days. But why is that? Why shouldn't you stop taking antibiotics as soon as you feel better? You might be surprised to hear that if you do, you might contribute to the creation of antibiotic resistant "superbugs!" Find out how these superbugs can develop in this activity by rolling dice to model how different bacteria respond to an antibiotic treatment. Read more

Have you ever wondered how many different types of animals live around your home, like in your backyard or a local park? Animals come in all shapes and sizes, each a small part of the amazing diversity of life. These differences can help people use systems to classify animals into different groups. One way people classify animals is by their phylum. Do you know which phylum you belong to? In this science activity, you will investigate the diversity (or biodiversity) of the animal life around… Read more

Have you ever wondered how an unborn chick breathes inside its shell? Every animal needs oxygen to live, so the chick must get air somehow! When an animal—including a human—inhales, oxygen enters its lungs and is then distributed to all the different parts of its body. The animal's metabolism converts the oxygen into energy. During this process, a waste gas called carbon dioxide is produced. To get rid of it, the carbon dioxide is carried back to the lungs, where it is collected… Read more
