Lesson Plan: Pascal’s Principle Physics • Second Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use Pascal’s principle to analyze the magnitude and direction of fluid pressure on an object.
Objectives
Students will be able to
- understand that at a point within a fluid, a force acts in all directions away from the point with the same magnitude in each direction,
- understand that at a point within a fluid, a force acts from all directions toward the point with the same magnitude from each direction,
- understand that an increase in pressure applied to a fluid from any direction increases the magnitudes of the forces that act at the points in the fluid,
- understand that the forces acting from the points in a fluid that is in contact with an object produce a pressure on the object that acts normally on the boundary between the object and the fluid in contact with the object,
- use the formula to determine magnitudes of forces applied to objects by fluids and vice versa.
Prerequisites
Students should already be familiar with
- ,
- .
Exclusions
Students will not cover
- compressible fluids,
- quantitative understanding of the flow of fluids due to pressure changes,
- particle models of fluids.
