You throw a ball in the air.

You see eight pictures a,b,c,d,1,2,3,4

Four pupils tried to make a picture of the distance of the ball from your hand (a,b,c,d)
Four pupils made a picture of the velocity of the ball (1,2,3,4)

Know that it is about the time that the ball goes up!

Phase 1 Think!

Part 1 choose a picture
What is your opinion about the pictures: which two pictures do you think are the right pictures?

Part 2 the Forum
Write your choices on the Forum .
Compare your ideas with the ideas of your partner.

Two possibilities: you agree or you disagree!

Part 3 agreement or disagreement

When you do not agree you discuss and at the end of your discussion you have the same opinion!

During your discussion you are allowed to do some experiments and to use the applet!
