Teaching Outlines

Concept #1 Early Atomic Models

Learning objectives

  1. Understanding of the atom evolved as experiments demonstrated results
  2. Current accepted model of atom rests on principles of quantum theory
  3. It is important to remember that atoms are not circles; though we use circles to represent

Notes for teachers

These are short notes that the teacher wants to share about the concept, any locally relevant information, specific instructions on what kind of methodology used and common misconceptions/mistakes.

Early Atomic Models

  • Process (How to do the activity)

Show the video, pause and discuss questions below

  • Developmental Questions (What discussion questions)
  1. What was the understanding we had on particles when the first atomic model was represented?
  2. How was the Rutherford experiment significant in understanding the model?
  3. How did the idea of a positively charged nucleus develop?

Concept #2 - Electrons occupy different energy levels in an atom

Learning objectives

  1. Electrons are distributed in an atim
  2. They occupy different levels based on energy
  3. There are parameters that define what levels an electron can occupy

Notes for teachers

It is important that students do not think of the electrons as "orbiting" the nucleus like the planets around the Sun.
