Grade 9 exploring technology
pneumatics and hyraulics unit
***please note - lesson plan attached altered in sequence****
began with scooper challenge using 2 syringes and limitd number of popsicle sticks , plastic spoon, paper cup and tape. In teams students are to design and build a scooper to scoop a tea light into a cup.
Begin lesson by asking if students have seen a bulldozer inoperation, or ever sat in a chair that can be raised or lowered, or opened a storm door? ASk what they think powers these devices?
Answer - fluid power
Move on to showing video on "everyday uses of fluid power"
Explain that fluid power makes work easier - think of simple machines
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.
scrap wood and unlimited syringes and tubing and miscellaeous supplies provided to students.
