Physical Science - Atoms and the Periodic Table
As an introduction to the lesson of the Periodic Table, we did a puzzle activity to help us understand the importance of classifying pieces by similar characteristics. It also helped students understand the reason for incomplete pieces on the table during Meneleev's time. New elements were yet to be discovered. We also made a model to demonstrate atomic number, mass number, and atomic mass. Students were able to understand the meaning of the word "isotope" by creating some.
