DO NOT WRITE ON ME!!! :
DO NOT WRITE ON ME!!! Answer the following review questions with a partner (only one partner, if you prefer to do it alone that is fine.) Write your answers on a piece of paper and hand it into the tray. Each person must have a copy of their own answers to hand in.
Quiz each other for fun to test each other’s science skills.
Be ready for discussion at the end of the period with the substitute.
