Fifth Grade, Aerodynamics & Hydrodynamics Science Projects (28 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!

Alternative energy sources are a big deal these days. One such source is the wind. Find out how a wind turbine can use the power of the wind to generate energy in this science fair engineering project. You'll design various blades to find out which produces the most energy, and put the wind to work for you!

Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate.

Have you ever ridden on a carousel, or a merry-go-round, at an amusement park? On a carousel, you usually get to take a seat on a wooden horse or other animal that spins around and around as the carousel is turned on and powered by electricity. Another smaller type of carousel that people can have in their homes is a candle carousel, which is powered by heat from candles. In this science project, you will get to make your own candle carousel and investigate how the spinning speed of the…

Engineers are trying to tackle the world's ocean pollution problem using robots. Some robots, like Mr. Trash Wheel and the ship featured in this Mark Rober video, are stationary and collect trash as it flows out of rivers before it gets into the ocean. Others, like the Jellyfishbot, are mobile and can squeeze into narrower spaces to collect trash:
Can you build and test your own trash-skimming robot? If you do not have access to a natural body of water to test it in, you can use a bathtub or a…

Have you ever wondered how a ship made of steel can float? Or better yet, how can a steel ship carry a heavy load without sinking? In this science project you will make little "boats" out of aluminum foil to investigate how their size and shape affects much weight they can carry and how this relates to the density of water.

Have you ever wondered how your smart devices can recognize and distinguish your face from that of others? In this project, you will explore how to create and modify a facial recognition model using a type of artificial intelligence known as neural networks. This project is designed for beginners and requires little to no coding experience. Ready to give it a shot?

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.

Have you ever looked up into the sky and seen not a bird, not a plane, but a hot-air balloon? They are definitely amazing and fun to watch! Do you think they are all the same size? Does size affect how long the hot-air balloon can fly? In this science fair project, you will launch hot-air balloons, powered by a toaster, and see how the size of the balloon affects its flight.
