Thinking is HARD (especially period 5 on a Monday)
Today I asked my class to investigate how far the end of a lever moved and how it was related to where the pivot was. Their first suggestion as to how we could find this out was to go straight to Google!!!!!
After an explanation about cardboard and skewers and several diagrams on the board the idea of being systematic about gathering data seemed alien to them. "How do I measure this," was a frequent question and the answer "That's a good question, how do YOU measure it?" was greeted with quizzical looks.
In 40 minutes one group of two had about 5 results, a singleton had several results, a trio had none and a group of seven had 2 results.
A couple of groups had opened up Google Sheets to record their results which could lead to good things.
Here are my results
