                     Is it Moving?
                     TEACHER NOTES:
This is from an activity in the TAKS Preparation Booklet from Region
4 Education Service Center, pages 148 – 149


Materials:
 metal toy car,
 40 cm long board (wood or cardboard),
 tray of items (thread, rubber band, magnet, wooden block, golf
  ball, balloon)

Observe in #2 means only using eyes (no touching)

 Possible answers:
    o Rolling the golf ball down the slope and hitting the car
    o Placing the magnet close to the car and pulling it along
    o Pulling the car by placing a piece of thread behind it
    o Blowing up the balloon and releasing the air near the car
    o Stretching the rubber band and hitting the back of the car to
       make it move forward

 Discussion Questions:
     o What is a common feature of all of the methods used to
       move the car? (a push or a pull is needed to move the car)
     o What do we call pushes and pulls? (forces)
     o What methods could you use if you could touch the board?
       (making a ramp – called an inclined plane – gravity is pulling
       the car down)
