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 agree you try together to design an explanation so you are able to explain to anybody else your choice.
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!

Prepare a presentation; explain to your classroom mates why your choice of pictures is the right choice! Make a little speech an put it down in het Forum with the name "our speech" and your names
