Objective:  Review major concepts with drama (pantomine) and discussion.

Materials:  index cards

Vocabulary:   None

Preparation:  Write out some action (work) situations on index cards.
    Ex. Ride your bike into a brick wall.
    Pull a sled over snow.
    Walk (street shoes) on an ice skating rink.
    Skate on an ice skating rink.
    Rub two pieces of coarse sandpaper together.
    Lift a heavy box up a short flight of stairs.      Note: This statement can be a lead-in to the next lesson.

Activity:  Have student volunteers act out the "work" on the index cards.  Classmates guess what the volunteer is doing using the vocabulary and ideas to develop the concept. Note:  The teacher may vary each action.--Rub coarse sandpaper--Rub greased blocks, etc.  Ask: What is happening?  Why is it happening?
Use the "lifting a heavy box" index card last.  Discuss possible ways of getting that box up the stairs, etc.  How can we make the work easier?

Closure:  (Optional:)  Say, Next week (tomorrow) we"ll explore simple machines that help make our work easier.
