# Physical Science SGI Group Lesson #13 (10-31-2017)

### Topic:

Periodic Table of Elements

3

### Unit S.M.A.R.T. Goal:

In this unit students will develop and use models in addition to using mathematics and computational thinking. Specifically in the field of Patterns, Energy and Matter, and Types of Chemical Interactions. The goal is for a student average of 85%.

### Objective:

Students will be able to better explain the following by the end of the  lesson today:

• Atomic Theory

### Behavioral Norms:

• Learn from mistakes
• Tolerance
• Participate
• Personal electronics only when appropriate

### Course Digital Resources:

Game -> Little Alchemy

Game -> Little Alchemy2

### Teacher’s Note:

Due to the lack of follow through on several students I am now going to issue you the Unit 3 material at the beginning of class and collect certain work back from you before you leave so I can close out your units at a faster rate so that they can be counted in a timely manner.

### Task #1 (Pgs. 1-3) (15 minutes)

We are going to learn about the following individuals:

Democritus

John Dalton

J.J. Thompson

Ernest Rutherford

For each person we look at we are going to write down their Time Period, Scientific Experiment, and Proposed Theory/Model on the chart provided to you on Pg. 1 of your units.

### Ticket Out the Door:

At the end of today’s lesson I will be passing out Post-It notes. On the Post-It note you receive write down the most interesting thing you learned today  and the most confusing thing you heard and put it on the inside of the classroom door as you leave today.

### Next Generation Science Standards Addressed:

Science and Engineering Practices:

Developing and Using Models

Planning and Carrying Out Investigations

Constructing Explanations and Designing Solutions
