Simulating The Kessler Syndrome: How Satellite Collisions Could Spiral Out of Control

Science Fair Project Idea

Engineering Design Process

What happens when a satellite collision in space leads to a chain reaction of more collisions? This project models The Kessler Syndrome: A scenario in which collisions between satellites in low Earth orbit create increasing amounts of debris, eventually making the region too dangerous for satellites or spacecraft to operate safely. By adjusting key variables like collision rates and debris generation, you can visualize how quickly space around Earth could become overcrowded, and explore… Read more

Have you ever seen a real virus? Probably not—they are so tiny that it is impossible to see them with your naked eyes. But how big or small are viruses really? The coronavirus Sars-Cov-2, which causes COVID-19, is about 120 nanometers in size. One nanometer is equal to one billionth of a meter! How many of these tiny coronaviruses do you think can you line up inside a pencil dot? In this activity, you will find out by creating a scale model that allows you to compare the size of many… Read more

Solar-powered Chemistry: Study Chemical Reaction Rates in Ultraviolet Beads

Science Fair Project Idea

Scientific Method

Most of the ultraviolet (UV) light produced by the Sun is blocked by the atmosphere, but some UV light does still reach Earth. It can be detected using electronic devices, but can also be detected with something called UV beads. UV beads contain a pigment that changes color when they are exposed to ultraviolet radiation from the Sun. In this chemistry science fair project, you will use UV beads to study how temperature affects the rate at which they lose their color. Read more

Solid Motor Rocket Propulsion

Science Fair Project Idea

Scientific Method

What does it take to launch a robot to Mars or for a satellite to explore our outer solar system? In this project you will explore the physics of a rocket as you predict its performance, launch it, and measure the actual results. This is rocket science! Read more

Have you ever added a spoon of sugar to your tea and wondered why it disappeared? Where did it go? The sugar did not actually disappear—it changed from its solid form into a dissolved form in a process called chemical dissolution. The result is a tea-sugar mixture in which individual sugar molecules become uniformly distributed in the tea. But what happens if you increase the amount of sugar that you add to your tea? Does it still dissolve? In this science activity, you will find out how… Read more

Do you have a favorite M&Ms or Skittle candy color? Have you ever wondered what dyes are used to make that particular color? Some candies are the color they are because of a single food coloring, while others may use a couple different dyes to create just the right appearance. In this activity you’ll get to do some scientific detective work at home to investigate which colored M&M’s candies use which dyes. If you have some M&M’s leftover… Read more

You use it basically every day and cannot survive without it—no it is not your cell phone, but water! It is one of the most essential compounds of the world and has become an increasingly important issue everywhere. You probably have heard that in many places droughts or water pollution limits clean drinking water supplies, and those supplies keep shrinking. When considering this, have you ever wondered why we do not just make our own water, and what water is actually made of? In this… Read more
