Build a rollercoaster


Foam tubes sliced in half marbles


Give the Beavers some foam tubes, masking tape and some a marble and by attaching tubes to furniture etc, see who can make the fastest and most fancy rollercoaster. Ask them to talk about what will happen and what did happen. i.e the marble flew out the end and why did it not fall out when it went over the loop etc.
