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, you can demonstrate on a larger scale. You can use Bernoulli's principle to help them explain how the airstream flows around the objects and determines their motion.
- Thorough explanations of airflow and lift are included for teachers' convenience
- A quick activity that demonstrates a commonly taught concept
