Unit I: Atomic Structure and Patterns
February 15, 2019

4. Objective
Students will know the basic unit of matter by taking notes on the atom, watching a video on atoms, building an atom and developing rules for the formation of atoms.
Mastery Level: 75% or better

5. Engage
Students brainstorm on scratch paper/Post-it notes what they have heard about the atom, or “atomic” things. Share what they know with a partner and/or the class.

6. Explore Students will watch “Just How Small is an Atom?”
Source: Nn0I
Students watch the video Just how small is an atom (TED-Ed- 5:27) and respond to corresponding Video questions – Just how small is an atom.

7. Explain
Students will create atoms (on their phones or on my computer) using
Source: an-atom
Students will work in groups of 2-3 people to complete the phet simulation worksheet

8. Extend & Evaluate
Atomic Rules Summary based on the phet simulation
