# Seventh Grade Aerodynamics & Hydrodynamics Science Projects (17 results)

You've seen for yourself, or in videos, planes flying, rockets hurdling towards space, boats racing through the water and submarines exploring the depths of the ocean. Have you ever stopped and thought about the aerodynamics and hydrodynamics involved in their operation? There is a lot of interesting science that goes into how they work! Check out these science and engineering projects to explore movement through air and water.

Science Fair Project Idea
 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),… Read more

 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

Science Fair Project Idea
 Race car drivers need every advantage they can get to give them the competitive edge in a race. In addition to human factors, like driving skill and reaction time, their cars must overcome physical forces, like air resistance, to maintain their high speeds. While this science project will not have you driving around a race track at 200 miles per hour, you will get to test how increased air resistance affects a real car's fuel economy. You will do this by measuring and comparing the gas mileage… Read more

 Time Required Long (2-4 weeks) Prerequisites None Material Availability This science project requires an adult volunteer with a driver's license and who is allowed to drive a car. A car that already has a detachable roof rack is recommended, but a detachable roof rack may be purchased to do this science project. See the Materials and Equipment list for details. Cost Average (\$50 - \$100) Safety Never try to record data or distract the driver while you are in a moving vehicle. Always collect your data when the car is parked at home.

 Time Required Short (2-5 days) Prerequisites You should know the basics of throwing a Frisbee (i.e., be able to play catch with a friend). Material Availability Readily available Cost Very Low (under \$20) Safety No hazards
Science Fair Project Idea
 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… Read more
