All about the PT!

Today we started class by discussing the dudes and their discoveries. These dudes (Democritus, Dalton, JJ, Millikan, Rutherford, Bohr, Heisenberg and Schrodinger) all did experiments and came up with different and improved atom models. The current model is the elctron cloud or quantum mechanical model.

Then we started talking about the periodic table and what a great tool it is. Students learned the difference between period and groups and some of the more notable regions of the periodic table. To practice we played a couple rounds of Guess Who using this knowledge where students tried to guess which secret element I had chosen. Good times were had by all.

Tomorrow we will learn more about the periodic table and have even more yes or no questions to add to the repertoire!
