For the bellringer today we identified simple machines found in compound machines that I brought from home.
Make up bellringer: What simple machines make up a pair of scissors?
First we watched some Rube Goldberg machine video clips including this one found on YouTube.
We also watched a clip of Robots and identified simple machines.
Next we learned about mechanical advantage. Mechanical advantage (MA) is the advantage gained by using a machine. To determine the MA of an inclined plane we divide length by height. To determine MA of a lever we divide the distance between input and fulcrum by the distance between the fulcrum and the output.
Last we did a lab involving levers and inclined planes.
