Bernoulli's Principle: Wind and Wings

Students explore aerodynamics and Bernoulli's principle by devising ways to keep bubbles aloft.

Thorough instructions are given to guide you through making a demonstration hydraulic pump from two plastic soda bottles. After using the resource to teach your class about Pascal's and Bernoulli's principles, turn them loose in groups...

Bring Bernoulli's principle before the eyes of your earth scientists! By setting two fans up facing each other, you can get a paper airplane to hover between them. Lift and drag concepts can be taught when you show this clip or perform...

A blow dryer and ping pong balls are all you need to demonstrate the amazing properties of air flow. In this demonstration, Spangler has a three year old boy as his assistant. Together, they make ping pong balls, a beach ball, and a roll...

A blow dryer and ping pong balls are all you need to demonstrate the amazing properties of air flow. In this demonstration, Spangler has a little boy as his assistant. Together, they make ping pong balls, a beach ball, and a roll of...

Two versions of this activity are presented for you to choose from when teaching about Bernoulli's principle in your physical science class. One is a hands-on activity, while the other would be best used as a demonstration during...

Demonstrate lift to the class that is studying aerodynamics. In the stream of air produced by a blow dryer, little physicists place a wad of tissue paper and a spherical figure to compare. Or, if you have a vacuum cleaner and beach ball,...

Do not let the pressure get to you. The first lesson in a unit of 22 introduces the concept of air pressure. Using background knowledge, the resource gives teachers the information they need to discuss how people measure air pressure and...

Eighth graders demonstrate Bernoulli's Principle in two simple activities after a discussion session on Bernoulli's Principle and its applications. Students divide into small groups to complete activities and wrap-up with a few review...

Lift—it is about the wing's attack. Using a virtual wind tunnel, pupils investigate wing shape and angle of attack. Learners use worksheets to record their observations and to convert verbal relationships into mathematical equations in...
