Bernoulli's Principle: as the velocity of a fluid increases, the pressure
exerted by that fluid decreases
4. Energy from the Sun heats Earth unevenly, causing air movements that result in
changing weather patterns. As a basis for understanding this concept:
e. Students know that the Earth’s atmosphere exerts a pressure that decreases with
distance above Earth’s surface and that at any point it exerts this pressure
equally in all directions.
Prior knowledge & experience:
What is air?
What can air do to other objects?
What will happen to the cans when a stream of air is blown between both cans?
Students will state that the cans will move in opposite directions?
Most students are unaware of Bernoulli's principle, and assume that an increase in the velocity of the air between the cans will cause the cans to move in opposite directions.
