Have you ever seen butterflies fluttering around outside, gliding through the air and landing on flowers? While they are delicate and fragile, butterflies are actually excellent flyers. They are so good, in fact, that scientists at Harvard University studied butterfly wing shapes as an inspiration for building a miniature flying robot. In this science project, you will do your own version of the Harvard scientists' experiment to measure the flight performance of butterfly wings.
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.
You can make a very simple hovercraft with a stiff, disposable plate-a pie plate should work well-and a balloon. Glue a square of cardboard in the center of the bottom of the plate. Make a small hole through the center of both of these layers. Enlarge the hole slightly with a pencil. Push a balloon through the hole so that the opening is on the front side of the plate, and rest of the balloon sticks out from the back. Blow up the balloon, then set the plate down (balloon side up). What…

Have you ever seen a helicopter flying through the sky? It can be difficult to do a science project with a real helicopter, so in this project we will show you how to make a miniature paper helicopter called a whirlybird. Will your whirlybird be able to stay in the air as you add paper clips as weights? Try this project to find out!
Do you dream about making deep, undersea voyages? Let this project take you 20,000 leagues under the sea! Investigate how submarines dive and surface by changing their buoyancy in this fun project.
Looking for an exciting new mode of transportation? In this science fair project, you will build a working hovercraft that will glide over surfaces on a cushion of air. And it's simpler to build than you might think!
Instant cold packs are popular with coaches and parents for treating minor bumps and bruises. The instant cold packs are not pre-cooled—you just squeeze the cold pack and its starts to get cold. So how does it work? In this chemistry science fair project, you will investigate the chemical reaction that occurs in instant cold packs.
How does a helicopter generate enough lift to fly? How does a speedboat get moving fast enough to pull someone on water skis? Here's a project on designing propellers to do the job.
How does weight affect a drone's speed? Is there a limit to how much weight a drone can lift? Find out with your own mini popsicle stick drone in this fun science project!
If you've played catch with both Aerobie flying rings and Frisbees, you know that the rings fly much further than the Frisbees with the same throwing effort. Why is that? Investigate the aerodynamics of flying rings and flying disks and find out!
