In this unit, 7th grade students learn about hydraulics and pneumatics. Students learn the difference between both and we create a Robotic Arm using hydraulics. Students work in teams and use the force of hydraulics to lift the Robotic Arm to lift a ping pong ball 1 foot in height and rotate 90 degrees and fall into a cup. Students learn woodworking skills and with safety supervision are allowed to use woodworking machinery.
