There will be a bin placed at the back of the classroom.
One member from each support group will be the leader and the rest of the support group are to be taken outside of the classroom and blindfolded. Blindfolded classmates then enter and are each given a crushed paper ball. The leader must then direct each member of the group to get the paper ball into the bin.
PSLS will observe each of the leaders' different ways of leading, for example, some might say "do this" or "throw it this way" without additional explanation, cooperation or attempts at encouraging the group. The group typically becomes frustrated so the paper balls will take some time to land in the bin.
