Science Fair Project Idea
Scientific Method
Have you ever heard that two phone books with the pages interleaved are impossible to pull apart? This might seem crazy, right? It is not that hard to slide a sheet of paper off the top of a stack of paper. How much friction can there really be between sheets of paper? In this experiment, you will use pads of sticky notes instead of phone books. How much weight can they support when you interleave the pages? Do you think you will be able to pull them apart by hand? The results might surprise… Read more

Scientific Method
Rockets are definitively an engineering challenge. These amazing gravity-defying machines have lifted test material, people, and even animals into space. Feel like building one yourself? In this science project, you will transform a water bottle into an aerodynamic bottle rocket with two compartments, one for the fuel and one for a payload. You will then test how well it performs when lifting mass vertically up into the air. Ready, set, soar! Read more

Scientific Method
Did you know that you can measure the speed of light using a microwave oven, some egg white, and a ruler? Find out how with this cool kitchen science project thanks to Mr. Nick Hood, a science teacher in Fife, Scotland. Read more
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

Scientific Method
Think it takes expensive, sophisticated equipment to measure the speed of light? Think again! Outfit yourself with a simple handheld laser pointer, a protractor, and gelatin, and you're ready to get started. Read more

Scientific Method
Have you ever wished you could fly to space? Space flight is getting more accessible thanks to reusable rockets that make getting to space much cheaper. Civilian astronauts can even buy tickets for a few minutes in space! But exactly how high is "space"? How do engineers predict how high a rocket will go and figure out how to make it land safely? Find out in this project as you explore the physics of suborbital space flight.  Read more
Science Fair Project Idea
Scientific Method
Can water remain liquid below its normal freezing point? If it does, that water is supercool(-ed). This project shows you a method for supercooling water. You can test water from different sources to see whether or not it can be supercooled. Read more

Engineering Design Process
Have you ever wondered what would happen if two satellites crashed into each other in space? While space may seem empty, Earth’s orbit is actually crowded with satellites and debris. In this project, you’ll step into the role of a space engineer, using real satellite data to model orbits, track their movement, and predict potential collisions. You’ll explore how gravity and speed affect a satellite’s movement and learn how scientists use simple math and code to prevent… Read more

Scientific Method
What do sand and cereal have in common? They are both granular materials, which means they are made up of solid particles, but they can actually flow like liquid. When two granular materials with very different-sized particles are mixed, you can actually separate each type by putting them in a rotating device called a tumbler. In this science project, you will examine how common household granular materials behave when mixed together in a moving container Read more

Scientific Method
So you've just finished mowing the lawn on a hot summer day, and you'd like a cold, refreshing drink as a reward. You look in the fridge, and oops! it's empty. The sodas are still sitting in the cupboard, at room temperature. What's the fastest way to get that soda down to a cold, drinkable temperature with materials readily at hand? Read more
