Last time the kids were here, they figured out the focal length of their given lens. But I was mean and made them dump all the lenses back in one box, no sorting. So today, they had to work together to find their original lenses. We started by writing what we were looking for on the board. I can’t say they collaborated as much as I would’ve liked but we did all have our lenses back within 10 minutes.

And apparently this class finally had a sunny day to go outside and try to set stuff on fire with lenses.
