Knowledge attack - Did
you know that a ball bouncing off the ground is similar to the way light
reflects off objects?
Materials:
- Ball
- Mirrors
- Torch
Procedure:
Part 1 - Outside on a
flat surface
With a partner, grab a
ball and bounce it between you and your partner. What do you notice about how
the ball bounces? Do you notice that the ball is bouncing off the ground in the
same angle that it hits the ground at?
Part 2 - Inside
Each student has a
mirror
Arrange your students
at desks in 2 rows
Give a torch to the
students sitting in the first desk
Turn off the lights.
Challenge the teams to
adjust their mirrors so that the light from the flashlight reflects off
everyone’s mirror on the team and reaches the last person in the row, as shown.
