Wednes-Day 1
AP Chem - continued learning the basis for the quantum atomic model: today we focused on Planck's particle and wave theory of light; he knew that he had to propose a quantum/particle nature of light in order to explain the "ultraviolet catastrophe" blackbody radiation curve.
His theory relating EMR's wave frequency to its energy per photon/quantum, was then supported/confirmed by Einstein's photoelectric effect experiments.
We painstakingly went through that experiment , making predictions, and seeing the empirical evidence that supported Planck's hypothesis.
We then did some quantum calculations, determining the energy per photon or per mol of photons for various forms of EMR.

Bio - we reviewed for Thursday's Unit 4 exam on DNA, the Cell Cycle (Interphase, Mitosis, and Cytokinesis), and Asexual Reproduction.
Homeworks looked good, so review them and also do the additional worksheets and quizzes posted on Edline; then, check your answers with the keys provided.
Should be a good day tomorrow!
