Show powerpoint - pneumatics/hyrdaulics as students review handout

Students work in groups to complete a hydraulic/pneumatic lab with syringes to examine the forces involved and the strength of fluid power

Final project is the "firefighting Robotic Arm" - in groups students design and build an arm with a working claw that must extinguish a tea light candle - pick it up with a working claw -  (located behind a 6 inch wall) and dispose of it in a container.
