The Benefit of Inclined Planes: Heave Ho!

Type of Resource



Students discover the scientific basis for the use of inclined planes. Using a spring scale, a bag of rocks and an inclined plane, student groups explore how dragging objects up a slope is easier than lifting them straight up into the air. Students are also introduced to the scientific method and basic principles of experimentation. To conclude, students imagine and design their own uses for inclined planes.

Performance Expectations

K-2-ETS1-2   Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.

K-2-ETS1-3   Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
