We agreed to figure out about sunrise and sunset first, as this would help explain lots of our questions (or so we hoped!).
Here are some of the initial models we developed:

We recognized many similarities in our models trying to explain sunrise and sunset, and that they included both the Sun and the Earth present. Most models included some ideas of movement, but we didn't really agree on the movements.
We also didn't agree on sizes--some models showed the Earth bigger than the Sun, and vice versa, while some even showed them being the same size. We also had differences in how we showed the light, and we didn't know if the moon had something to do with all this.
We DID agree though, that a 3D representation of this phenomenon might help us. So we set up shop with some flashlights and Earths. And here's what this looked like:

Students even wanted to take pictures from their own view...
We will finalize our ideas tomorrow as we establish consensus. Hopefully we can see what other questions we can answer!
