Supplies

  • 1 Newspaper
  • Balls (rubber or wooden balls)
  • Clay (or playdough)
  • Pebbles (round smooth pebbles)
  • Wood (Wooden plank 3-6' in length)
  • Blocks (or weights)

Steps

  1. Divide children into groups.
  2. Roll the newspapers into tight small balls or make balls out of clay and or play dough.
  3. Place the wooden plank on a slant with an angle of 45-50 degree. Stabilize the plank with weights or blocks to prevent movement.
  4. Have children take turns, rolling the balls down the plank.
  5. Discuss their observations. Which balls roll in a straight line, which wander? Does the weight of the ball make a difference? Why don't things roll up the plank?
  6. Discuss other things that might roll; oranges, eggs, toys.
