Science Fair Project Idea

Scientific Method

Want to start a garage band, but Mom or Dad won't let you because it will make too much noise? This is a good project for someone who is interested in acoustics and likes to build things. Who knows, it might help you figure out how to make everyone happy. Read more

Have you ever been zapped by a door knob or another person? It feels like a little electric shock and usually happens on cold and dry winter days. Where is this shock coming from? Why is it that sometimes you get zapped and sometimes you don't? It all has to do with static electricity, which can build up in some materials and then be transferred from one object to another. Sometimes you can even see a spark fly between them! In this science activity you will explore how well materials around… Read more

Measure the Frequency Response of a Paper Speaker

Science Fair Project Idea

Scientific Method

Can you build a working speaker out of paper? How does a speaker's ability to play low or high-pitched notes depend on its size? Explore the science of sound in this project as you build and test your own speakers in order to answer these questions! Read more

Try the Mythbusters' "Phone Book Friction" Experiment at Home

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

Use a Catapult to Storm Castle Walls

Science Fair Project Idea

Scientific Method

You may have seen movies or read books where armies in medieval times catapulted large rocks or other objects at castles (or each other!). These armies used different types of catapults to accomplish different goals — for example, launching things over or into castle walls to knock them down. In this experiment, you will use a ping-pong ball catapult to lay siege to a "castle" and find the right settings to hit your targets. Read more

Distance and Constant Acceleration

Science Fair Project Idea

Scientific Method

Have you ever dropped something and wondered how fast it was moving while falling? If it was something fragile, like a cell phone, you might not have been thinking about this at the time — you may have been too busy trying to grab the phone! But you probably wanted to find out just how hard it hit the ground afterwards. We know that gravity forces an object to fall, but how does this affect how quickly something falls and how hard it hits the ground? For example, did the phone move faster… Read more

Do you like popcorn? It’s not only a tasty snack but also fascinating to watch when it pops in the pot. But why does it do that? What makes the small popcorn kernel jump into the air and change its appearance? Where does the characteristic popping sound come from and does every corn pop? There are many good questions about such a simple snack. Are you curious to find out some answers? In this activity you will do some popcorn science and even get to snack on your experiment.

Measuring the Surface Tension of Water

Science Fair Project Idea

Scientific Method

Did you know that when you dip your finger in water and pull it out, the water is actually pulling back on you? Here's a way you can measure how much. Read more

Particles in the Mist: See Radioactive Particles Decay with Your Own Cloud Chamber!

Science Fair Project Idea

Scientific Method

Are you fascinated by radioactivity and the emission of particles caused by the disintegration of an atom? This science project enables you to observe safely a spectacular display of radioactive decay. Following the instructions in the Procedure, you will be able to isolate a safe radioactive source and build a cloud chamber to watch the radioactive decay. Then you will use your cloud chamber to discover if a plastic lid can shield you from this type of radioactive decay particles. Read more

See Air Currents with Shadowgraphs and Schlieren Images

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what the air currents look like around a candle? What about cold air flowing around an ice cube, or warm air rising from your hand? What about when you sneeze? We are surrounded by air currents all the time, but these subtle movements are completely invisible to the human eye. In this science project, you will take advantage of small changes in air density to make air currents visible in regular photographs and videos, using techniques called shadowgraphy and schlieren… Read more
