Hydraulic Advantage

Type: Mini-lesson

Theme: Geometry

Grades: 6, 7, 8, 9, 10, 11, 12

Learning Target: Students will calculate the mechanical advantage of a hydraulic lift system using area, volume, and the pressure equation.

The math learning targets are:

  1. Students will calculating volume of a cylinder (Slides 2, 5, 6)
  2. Students will use ratios to solve for unknowns (Slides 8, 9, 10)
    (cross-multiplication is OK)

The physics learning target is:

  • Students will calculate the change in volume to learn that in a closed hydraulic system, volume of the liquid does not change and does not compress (Pascal's principle).

  • I can reason abstractly and quantitatively.
  • I can look for and express regularity in repeated reasoning.
  • Cause and Effect
  • Stability and Change
