Please go to the Science homepage and look under the files section on the right of the page for a link to a powerpoint about the uses of simple machines.
The 6 types of simple machines are: wedge, screw, inclined plane, wheel and axle, lever, and pulley. Click the link for an overview of the machines and their uses. http://www.mikids.com/Smachines.htm
Here the concepts that we covered in the beginning of our force and motion unit . These concepts are somewhat challenging, so use the provided resources for some review!
