Sample Instructional Approaches:
1. Layout the models in the shape of the periodic table to discover trends
Students should notice: Protons and Neutrons in the middle - Nucleus Electrons on the outside – Electron cloud Trend of increasing protons across a period Protons and Neutrons sometimes match, but not always Number of protons equals the number of electrons Valence electrons are the electrons on the outermost ring
2. Have the students look at the cards next to a periodic table and make predictions Have the students predict what determines the atomic number. Have the students predict how the atomic mass was determined.
3. Use the models to match the name with the correct model.
4. Project a model on the board and have students write the name on white boards.
5. Project a name on the board and have the students find the correct model.
6. Project a model on the board and have the students write which group/period the element should be located.
7. Project models from group 1 and group 18 on the board and have the students determine the element’s reactivity.
