Sunny Day Results (Happy Belated Pi Day!)

This week I had some sun to do some baking on the roof outside my classroom window. This weekend was "Pi day" - Albert Einsteins birthday, so I had a belated "Pi Day" with my classroom development group.

I have a classroom development group that stays after once a week to build things in the classroom, test out new ideas and develop new units. They will be helping me build and test the solar unit that is quickly approaching at the end of this school year!

To prepare them for this and excite them about what we will be doing, I showed them what a homemade solar oven looked like, how it was built, and we cooked a small apple pie on the proverbial window-sill while we talked about other classroom activities.

Because I was not able to pay close attention to it, the oven only reached 190-200 degrees F. This is making me think of building some kind of sun-tracking device so that I can cook things out of the window without having to adjust every 15 minutes or so.
