California Science Content Standards:
- Chemistry Grades 9 – 12. Standard Set 5. Acids and Bases.
Next Generation Science Standards:
- HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
- HS-PS1-3. Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
Lesson Introduction:
You will be creating a multimedia presentation that will demonstrate the key concepts about Acids and Bases that you have learned from the previous reading and other resources.
Task:
You will be organized into groups of three. You will create a multimedia presentation in Google Drive that demonstrates your understanding of Acids and Bases. The presentation should be in Google Presentation format. For purposes of collaborating on Google Drive, please do not use Microsoft PowerPoint. The content of the presentation must satisfy the following goals of the topic:
- To understand the differences between acids and bases.
- To be able to identify different acids and bases.
- To understand the difference between strong and weak designations, and how it relates to pH.
- To understand the action of H+ and OH- in forming solutions.

Lesson Process:
Review previous lesson and relevant textbook chapter on acids and bases.
One group member should create a new Google Presentation and share it with the other members and your instructor with commenting and editing privileges. This will allow everyone sharing this file to collaborate and make individual edits.
The presentation must contain 5 links, 5 relevant photos or clip art, and 1 embedded video. Please cite all sources. (Clip art does not have to be cited.)

Rubric:
| Excellent (5) | Adequate (3) | Not Adequate (0) |
| Identifies 4 or more key differences between acids & bases | Identifies 2 to 3 key differences | Identifies 1 or 0 differences |
| Identifies 3 or more different acids and 3 or more different bases. There are examples for strong and weak versions for each. | Identifies 3 or more examples for each, but does not specify which ones are strong or weak. Or identifies 2 examples of each and specifies which are strong and which are weak. | Does not meet the requirements for Adequate. |
| Demonstrates action of H+ and OH- in forming solutions | Demonstrates action of H+ and OH- in forming solutions, with some error | Cannot demonstrate action of H+ and OH- in forming solutions |
| Used Google Presentation and collaboration tools correctly | Used Google Presentation with some errors | Used other Presentation format |
