Tues-Day 2
AP Chem - we discussed the evolution of the progressively more accurate and precise models of the atom; better technology led to a better understanding of the evidence via more revealing data, which led to better technology, and so on.
We elaborated upon the Rutherford nuclear atomic model, and then began to discuss emission spectra in order to discuss Bohr's atomic model. We will discuss Planck's quantum theory of energy so that we can fully discuss the Bohr model of the atom and beyond.
Bio - we reviewed the types of asexual reproduction seen in various species in nature; then, we discussed methods of asexually reproducing certain plants via cutting, grafting, or layering. We saw videos of the grafting method; these videos will be available on Edline.
In 7/8, we discussed a complete scientific investigation from observations to question to hypothesis to controlled experiment to sample collected data to conclusion; we will do an example from scratch tomorrow.
We then viewed cells of rapidly dividing onion root tip cells, and of fish blastula (embryo) cells, for our mitosis/cell cycle lab.
