Explore Satellites with Powerful Simulation Software

Science Fair Project Idea

Scientific Method

The first man-made satellite, the Sputnik 1, was launched in 1957. As of late 2020, more than 2,600 man-made satellites orbit Earth, with a little over 70% of them in low Earth orbit. If you would like to delve into how satellites and their sensors are configured, or into how their orbits are planned—and do not shy away from a little programming—this project is for you! With the help of FreeFlyer®—powerful software that allows you to simulate satellite orbit and… 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

You probably know that water never stays still. But did you know that there is something called the global “ocean conveyor belt” that moves massive amounts of water from one ocean to another? These water currents are essential for mixing and transporting nutrients and oxygen, and play a critical role in our climate. This is because they move warm and cold water over very long distances, which affects the temperature of the landmasses that border the ocean. The Gulf Stream, for… 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

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

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
