A 2-page worksheet
that provides a basic summary of the main scientists who contributed to the development of the atomic model
I typically use this as a summary reading exercise
that is designed to be a supporting document to my PPT on the development of the modern atomic model. After showing the relevant PPT slides to my students and viewing a brief video clip, I hand out this reading exercise and review questions for them to work for the remainder of the lesson and for homework. A link to my Atoms and the Periodic Table PPT presentation is found below:
