Have you ever noticed how some jet planes have small, vertical projections as the tips of the wings? They're called winglets. What are they there for?

Have you ever flown in an airplane, or looked up at one flying in the sky, and wondered how such a massive machine can stay in the air? Airplanes can stay in the air because their wings, also referred to as airfoils, generate lift. Engineers use devices called wind tunnels to experiment and test different wing shapes when they design new airplanes. Wind tunnels let engineers make careful measurements of the air flow around the wing, and measure the amount of lift it generates.
If you can get…

Hydrogen peroxide (often used as a disinfectant) has also been approved for use in pesticides. This science fair project investigates whether hydrogen peroxide has any effects on seed germination or on roots of plant cuttings.

Visit the USGS Earthquake Hazards Program to find out about global patterns of earthquake incidents (USGS, 2006). Can mapping earthquakes help identify fault lines? They also have a list of science fair project ideas. Another great resource for earthquake-oriented science fair projects is by Jeffery Barker (Barker, 1994). Build a model to study the forces of an earthquake using sandpaper-covered blocks. What are the forces involved? How are stress and friction in balance along a fault line?…

Did you ever have a favorite toy like an action figure or doll that could light up, make noise, or move? This project will show you how to make your own interactive toy using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. The version you make does not have to be a robot; it can be any shape and have any sound effects you want.
IMPORTANT: The instructions for this project were originally written using Scratch 2 on a Raspberry Pi 3B+. If you are using a…

What is cancer? How does it develop? Doctors and scientists have asked these questions for hundreds of years to understand cancer and find treatments. In this science project, you can investigate these questions too by building a simple model and exploring how environmental and genetic changes affect the development of cancer.

Using just a single sheet of paper (8.5 x 11 inches) and up to five paper clips, can you build a bridge that will span 20 cm and support the weight of 100 pennies? The area beneath the span must be free (so that boats can pass beneath it). To test your bridge, place two books 20 cm apart, and set the bridge on the books, spanning the gap. Do not fasten the bridge to the book (nor to any other support). Does your bridge hold as much weight as you expected it would? If your bridge fails…

If you want to get your friend's attention at a crowded sporting event with lots of people cheering, you need to shout. If you're trying to do the same thing in a quiet library, a whisper works. The detection limit for each of our senses depends on the amount of "background" stimulation that is already present. This project uses an LED control circuit to investigate detection of changes in light levels.

Does listening to classical music help or hinder concentration and performance on cognitive tasks? You'll need help from a teacher to design two short, age-appropriate worksheet tests for this experiment. The tests should be of equal difficulty. You'll also need the cooperation of several additional classroom teachers in order to test enough students (at least 50-100, see the Science Buddies resource: How Many Participants Do I Need?). Half the students will take test A while listening to…

Balloons are a festive addition to many celebrations. You've probably noticed, though, that over a short period of time, helium-filled latex balloons start to lose their buoyancy. So when you're planning your next party, how soon can you buy the balloons in advance before they start deflating? In this science fair project, you will use a simple scale to measure the lift supplied by a set of balloons, and determine the rate of lift decay.
