Air Pressure Curriculum

Section 3—Lesson 9: Relational Causality and Bernoulli's Principle

Understanding Goals

The following transfer lesson enables students to apply their understanding of pressure in a new context; specifically lift and Bernoulli's Principle.

Subject Matter

• The pressure in a fluid decreases as the speed of the fluid increases in a steady flow.
• Lift is possible because air has to travel further over curved surfaces than straight surfaces.

Causality

• A relational causal model can be used to understand lift and Bernoulli's Principle.
