Wednes-Day 2
AP Chem- we did a few electrochemical cell calculations and then we related the cell potential/voltage to the maximum amount of electrical work that could be produced per mole of reaction, that is, we relate E cell to the change in Gibbs Free Energy and also to K, the equilibrium constant. We noted that just a couple of Volts of cell potential translates to an insanely large K value.
Bio 6- Here is the link that I mentioned regarding tracing your genetic ancestry back to various countries as you go back in time: https://genographic.nationalgeographic.com/genographic/lan/en/atlas.html
Give it a try.
We discussed Lamarck's theory of evolution, which was one of the first scientific explanations of how species/populations changed/evolved. His mechanism of use and disuse and inheritance of acquired traits was ultimately disproved by experiments that showed that traits acquired by parents during their life were not passed on to their offspring (e.g. loss of tails in mice does not get passed on).
We then reviewed Darwin's Theory of Evolution, showing the logic of the mechanism, which was based on decades of observations of nature.
Bio 7/8- Here is the link that I mentioned regarding tracing your genetic ancestry back to various countries as you go back in time:

We did some worksheets regarding geological/paleontological evidence for evolution.
