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.
