2. Environmental factors affecting how something "disappears"
3. Organisms and what they eat
Questions about people's involvement, bones, and other miscellaneous things can wait!
We agreed that the questions about plants, environmental questions and organisms' eating habit might best be answered by going outside and seeing these things in action, but we also figured out that that might be really hard. We'd have to go outside a lot, and while that would be fantastic to do, it might be a bit challenging for many reasons.
So...some students suggest we build some models to mimic the outside and see if we could gather evidence to answer some of our questions. Mrs. Brinza had a whole bunch of 2L bottles lying around (science teachers collect A LOT of stuff), and we agreed this would help up build some models that could answer some of our questions. Since they are transparent, we can easily see what's going on inside them. We first discussed what might need to go into these models to answer our questions, and we came up with these ideas:
