The Municipal Community Center gave your school a plot of land to create a community garden.


You and your classmates need to plan how to clear out the land of outgrown weeds and rocks.


You were able to remove the weeds and rocks. The only thing you need to remove is a boulder!

Drag the boulder with a pulley and a large truck.
Break the boulder with a wedge and hammer, and carry the pieces away with a tractor.
Use a lever to move the boulder out of the ground and a ramp to load the boulder onto a pickup truck.

Select each marker point to observe the impacts of this solution.

You identified the most efficient solution.Your next step is to identify the combination of simple machines that would remove the boulder in the most efficient manner.

Based on what you learned, select the option you think is the best one to accomplish the task.

a = 1.5 m
b = 0.3 m
L = 3.0 m
H = 0.5 m
Drag the correct values for the mechanical advantage of both the lever
and the ramp to the appropriate location.
Lever Mechanical Advantage: _____
Ramp Mechanical Advantage: _____
Mechanical Advantage Values:
5.5
6.0
5.0
6.5
Good work! You were able to remove the boulder from the land. With this computer simulation,
you were able to solve a real-world problem.
The community garden looks great!
