I use these recording sheets when teaching simple machines. I have used them in several different ways. I have formed 6 groups and given each group several books on one simple machine. Then I have groups share what they have learned and the other students in the class take notes. I have let them research simple machines online and had them record what they have learned. I have also shown some simple machine videos and paused for discussion and note-taking. The worksheets are made to give you flexibility and to save you time!
