Georgia Standards (GPS) that can be used:
S4P3 Students will demonstrate the relationship between the application of a force and the resulting change in position and motion on an object. a. Identify simple machines and explain their uses (lever, pulley, wedge, inclined plane, screw, wheel and axle).
S8P3c -demonstrating the effect of simple machines (lever, inclined plane, pulley, wedge, screw, wheel & axle) as an attachment.
SPS8 Students will determine relationships among force, mass, and motion. e. Calculate amounts of work and mechanical advantage using simple machines

Generalization ideas:
Going to Home Depot, Lowes, or Wal-Mart to have students to locate the types of simple machines would be a good activity for generalization. Be sure to arrange ahead of time so an employee can assist in this activity. Practice this activity in your classroom so they know what they are looking for – don’t just say “go find a simple machine that is a screw”. Show them objects – match objects to the pictures/symbols/words of the the simple machines. Practice around the school before you go on CBI. Remember that a field trip involves instruction BEFORE, DURING and AFTER the actual trip.
