Have you ever wondered why we sweat when our environment is getting hot or when we exercise? Sweating is a life-saving strategy that cools our body down and maintains our body temperature. Without sweating, our body cannot regulate our temperature, which can lead to overheating or even heatstroke. But why does sweating have a cooling effect? The answer is evaporative cooling. Turning a liquid such as sweat from its liquid state into a gas requires energy. This energy is taken from our body, or… Read more

Summer is the perfect time to take a stroll at the beach and walk barefoot along the shoreline. While doing that, have you ever looked at your footprints in the wet sand? If so, you might have noticed that with every step it looks like the sand around your feet dries out. Why is that? These dry footprints are caused by the pressure of your feet. You will find out exactly how this happens by doing this beachy activity! Read more

As I was buttering toast on a beautiful Sunday morning, one piece slid off the table and tumbled down. It smacked buttered-side down on the carpet. “Bad luck” flashed through my head—but was it a matter of chance, or was the toast doomed to reach the ground buttered-side down? Time for science to tell us! Take a slice, try it out and learn about the science behind a falling slice of toast! 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

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 Does Your Eardrum Work?

Science Fair Project Idea

Scientific Method

Eardrums are membranes inside your ears that vibrate when sound waves hit them. These vibrations are converted into electrical signals and sent to your brain, which allows you to hear sound. The frequency response of your eardrum, or the range of frequencies that will cause it to vibrate, determines your hearing range. Typical human hearing ranges from about 20 Hz up to 20,000 Hz, although the ability to hear high frequencies typically degrades as you get older. Some other animals can… Read more

Did you know that airplanes and sound have something in common? Can you guess what it might be? Air pressure! It is fascinating how air—something that is so fluid and invisible—can power an amazing number of fascinating phenomena. In this activity you will use your own breath to blow a small paper ball into an empty bottle. It sounds simple, but is it? Try it out and see for yourself! Read more

If you’ve ever accidentally let go of a Helium balloon while outside, then you know that some gases are less dense than others. In the case of your Helium balloon, it most likely floated away before you could catch it, because Helium is much lighter (or less dense) than the air in our environment. We don’t often think about gases having density, but they do! In this activity you’re going to explore the different densities of some common household gases, including the air that… Read more

How Long Will My Sleepy Yo-yo Sleep?

Science Fair Project Idea

Scientific Method

Sometimes, simple toys can be quite complicated. Take the yo-yo. It's a fun toy and there is nothing simpler than a string wrapped between two connected disks. But there's a lot of physics that makes a yo-yo work. In this science fair project, learn more about how and why a yo-yo works. You will investigate the effect of string length on the yo-yo's "sleep" trick time. If people ask why you've got a yo-yo with you all the time, tell them that while it looks like you're just having fun, you're… Read more
