A PowerPoint and two activity sheets (with cards) for students to complete. Firstly on the conservation of energy with examples on the board and a worksheet to complete. Secondly the use of the efficiency formula with students using a sheet and a set of cards (to be placed around the classroom) for them to gather information from. The wrap up activity is a splat game whereby two students can be brought to the front and play against each other. It is the first person to hit the correct answer with their hand (or fly swatter if you have one). openclipart.org
