Did it ever occur to you that tennis, bowling, Newton’s cradle, and cars bumping into each other all revolve around collisions? It is fascinating how a few rules of physics can predict the outcome of these collisions. You can discover these rules yourself with a fun homemade toy. Do the activity, play with the toys you make and be one step closer to understanding what happens when you shoot a marble into another! Read more

Have you ever thought about the sheer number of words that exist in the English language to describe sounds? A noise can be a thud, a clang, a bang, a pop, a crash, a splash, a clatter, a buzz, a tinkle, and many more! You can probably think of an example for each of these—but if you heard the sound, could you say what produced it? Read more

Create a Marshmallow Map of Your Microwave Oven!

STEM Activity

Have you ever bitten into a microwave burrito, and the first bite is scalding hot, whereas the second bite is still frozen? If you’ve experienced this, then you know that microwaves have hot and cold spots, which is why they usually have a rotating tray to ensure that your food is evening cooked. In this activity, you’ll use marshmallows to map out where the hot and cold spots are in your microwave. Get ready to heat things up! Read more

Do you enjoy watching mysteries or crime investigation shows? Every criminal leaves behind evidence at the crime scene. The trick to catching the criminal is collecting all of the evidence and making sense of it. This is what a forensic expert does. In this bloody, Halloween-themed science activity you’ll be correlating the size of blood stains to the distance they fell, but don’t get too grossed out; you’ll be doing it with fake blood. If you like figuring out mysteries, this… Read more

Do you like gift wrapping? If you do, you have probably curled a ribbon with scissors before. Have you ever wondered why the ribbon curls when you run a scissor blade down one side of it? The answer is that when you apply pressure on the ribbon with the blade, the outer layer of the ribbon stretches and expands. This makes the outside layer of the ribbon longer than the inside layer that is pressed against the blade. As a result, the ribbon starts to curl to make up for the different lengths of… Read more

Do you like watching raindrops on your window as they move and run down the glass? It is fascinating to observe how some of them just sit there by themselves, whereas others combine to build a larger drop. Have you ever wondered what makes them move and behave in different ways? Controlling and influencing wetting, the spreading of liquids on surfaces, is actually important for many industries. For some purposes, you want a surface to repel a liquid; just think of your water-repellent jacket as… Read more

How many ball sports can you name? How many of those have several balls at once in the game? Almost none, right? Games that do use several balls at a time most likely use balls of the same mass, volume, and material. Would having two balls of a different mass make a game very difficult? In this activity, you will explore what might happen if you were to add a tennis ball to a basketball game, or a tiny ping pong ball to a tennis game, or any other combination. Ready to be surprised? Try it out! Read more

Explore Interplanetary Spacecraft Maneuvers with FreeFlyer®

Science Fair Project Idea

Scientific Method

If you are interested in space travel and willing to do some coding, this project is for you! It uses FreeFlyer®—powerful software that allows you to simulate space travel—to explore essential mission questions. Space travel is complex. Many factors influence the trajectory of a spacecraft. Simulations like the ones generated by FreeFlyer are powerful, as they allow you to analyze each factor in isolation, and then visualize the effects in various ways. Once you familiarize… Read more

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
