In any case, this is what we discussed in class today. We started with a small demo using grapes. In this, we placed raisins, a skinned grape, a halved grape and a whole grape into a solution of pure water, and the same into a solution of 91% isopropanol (9% water.) It turned out that everything but the raisins lost mass in the alcohol, and everything gained mass in the pure water. The questions was: why? We then looked at two videos that partially address the question. The important thing to realize is that water will also move on its own, just like dye or anything else. And, just like dye or anything else, it always spreads out from areas with lots of water (like pure water) to mix into areas with less water (usually because stuff dissolved into the water is taking up some of the space.) It turns out, when this happens to cells, the cells can shrink as water moves out or expand and even explode as water moves in. The idea to keep in mind is that the water always moves from where it is most concentrated or pure to where it is less concentrated or pure. The video below shows how this can happen. (My favorite bit is towards the end.)
1. How did the relationship between the governments and the Christian church(es) change from Christianity's beginning in Roman times, to the Medieval era?
2. What were people or groups that the medieval catholic church was afraid of? Why? How did they try to fight these forces?
3. In your opinion, what was the effect of Christianity on Medieval Europe?
Pick two of these and respond to them separately. Due tomorrow.
Oh, one last thing. I'll attach the schedule for conferences below.
