Fri-Day 1
Bio- we discussed the Biodiversity lab, focusing on the various types of evidence that distinguishes closely related and more distantly related species: DNA evidence via gel electrophoresis, amino acid sequence evidence via DNA to mRNA to amino acid transcription and translation, comparative anatomy, and comparative cytology/embryology.
Chem 7- we discussed nuclear equations, showing that the mass numbers and the atomic numbers must balance on both sides of the equation.
We saw the criterion for an unstable radioisotope: either a too high or a too low neutron to proton ratio in the nucleus. Unstable nuclei emit one of four main types of particles: alpha, beta (-)/electron, beta (+)/positron, or gamma ray photons.
Chem 8/9-we discussed nuclear equations, showing that the mass numbers and the atomic numbers must balance on both sides of the equation.

We also discussed the metal activity series lab.
