What makes some objects more streamlined than others? Find out which ordinary objects around your house are made to move smoothly through the water in this easy science fair project. Which objects will produce the most drag when pulled through the water?

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…

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?

If you have an air hockey table, you know that the puck floats on a thin cushion of air when the table is turned on. With little friction, the puck can travel very fast. How much lift force is created by the air? Add small amounts of weight to the puck and see when it no longer floats to measure the lift force. How many air holes (on average) support the puck? How much force is generated by each air hole? Will a puck with a larger surface area, supported by more air holes (on average),…

Drones—also called quadcopters or unmanned aerial vehicles (UAVs)—are an increasingly popular toy for hobbyists. Some companies even want to use them for business purposes, like delivering packages right to your doorstep! However, drones typically have a rather short battery life. Does the added weight of a package affect a drone's battery life? Try this project to find out!

NGSS Performance Expectations:
You can measure the viscosity of a fluid using a glass tube and a marble with slightly smaller diameter than the tube. Seal one end of the tube. Fill the tube with the fluid to be tested. Drop the marble into to the tube and measure the time it takes to fall a fixed distance. Repeat the measurement several times, and use the average value. How does viscosity change with the amount of sugar dissolved in water? How does viscosity change with temperature?

How do quadcopters (drones with four propellers) steer? Find out in this fun project as you program an Arduino to steer a mini popsicle stick drone!
See this page for a complete list of our mini drone projects. You may wish to do the projects in order.

Rocket design and operation is a fascinating field and analyzing the flight path provides insight into the rocket's performance. In this project, you will take measurements of the flight path to evaluate how a change in the rocket design or launch procedure impacts the rocket's performance.
Initially, while the bottle rocket expels water (or the rocket expels exhaust), the rocket gets a boost. This push is referred to as thrust and projects the rocket forward. Earth's gravity pulls the rocket…

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…
