3 Handles

November 2, 2010

I showed the class the web page on lesson plans
for 3 handles and brought in an example I had made

with a lever being moved up from underneath

and lever being moved by a connection through it

and two levers being moved up and down with "handles" or cams hitting them from above.

Then they made examples.

Through                                  Over


Under, over, and through


They are going to make a poster of their machines.
