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

Stealthy Shapes: How to Make an Aircraft Invisible to Radar

Science Fair Project Idea

Scientific Method

Have you ever dreamed about becoming invisible? Or about making something else invisible, like the mess all over your room? Invisibility may sound like the stuff of science fiction (remember Star Trek's "Cloaking Device"?), but in reality, military vehicles, like planes and ships, can be made less observable, or even invisible, to different detection methods—like radar, sonar, or infrared sensors—by using stealth technology. In this engineering science fair project, you'll find out… Read more

Stop the Train! Magnetic Brakes for a Maglev Train

Science Fair Project Idea

Scientific Method

Did you know that you can use magnets to build a train that floats above its tracks? In this project, you will also use magnets to make the train stop, preventing it from crashing into the end of the track. Will adding more magnets help the train stop sooner? Read more

Strength of an Egg: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a materials science family experiment and science fair project that asks you to rethink what you know about eggs. Are they fragile? Or are they strong? If you've ever accidentally stuck your finger through one in the kitchen, you may think you know the answer! But the shape of an egg can support a surprising amount of mass. It is a shape, in fact, that can be found in architecture. How much mass can eggshells hold? Put it to the test with a… Read more
