Here is the handout they received. We got through example 3 together and then moved on to this. Yes! We were going to go outside! I showed them how a clinometer works.
I asked what data they would need to collect and we came up with this diagram:
I put them in random groups and told them they had 15 minutes to be back in class. Out they went (it was beautiful out) and started measuring. Some groups were finding the height of a tree, others a hydro pole and one group the light standard. They came back in the school to take measurements (as a large group) for the ramp then we all headed back to our classroom. They wrote the measurements they took for the ramp on the board for everyone to use:
And that was it. Tomorrow they will do the calculations and practice a little more trig.
