New Lesson: Charge!

Last summer I sat next to a power outlet for more than two hours, taking screenshots of my plugged-in-and-charging cell phone once every four minutes for nearly 2.5 hours. The result? A linear modeling task with a nice twist near the end.

I’ve presented the lesson in a variety of workshop settings (each time it was well received), but this week marks the first time I used it with my own students. It was an absolute blast.

The full lesson is available here. I’d love to know what you think, as well as what you’d add or tweak (especially if you test it out with your own students).
