Atoms and the PT - Begin

Today we started on atoms. The students did readings on atoms over the snow days so they were a little prepared. I cleared up any confusions and the students practiced using the periodic table and calculating the number of protons, neutrons, and electrons.

Next students got a sample of Beanium and had to determine the number of protons, electrons, and neutrons, the atomic number and the atomic mass number. Then students compared the Beanium sample to a real element on the Periodic Table.Jen and James arranged their beans like an actual atom with the protons and neutrons in the center. Delafayette and Corrin count beans
Chelsie kept her beans in the bag to count them
