The first partnership that wins two games wins the rubber. They score a 700 point bonus if they won in two games, or 500 points if their opponents ... made a game. If the rubber ends prematurely for whatever reason, the pair (if any) who scored one game while the opponents did not are awarded 300 points.

Just about everyone has used rubber bands, but few people have taken the time to observe the less obvious properties of these everyday objects. In this activity you will examine the thermal properties of rubber, that is, the behavior of rubber as it relates to heat, a form of energy.

Vulcanization of rubber creates more disulphide bonds between chains so it makes each free section of chain shorter. The result is that the chains tighten more quickly for a given length of strain. This increases the elastic force constant and makes rubber harder and less extendable.
