Finish IMF Project

Goal:
Complete the IMF project.

Agenda:
Warmup
Review
Lab Cleanup
Work Time!

Warmup
Log in to Socrative and answer the question, what is the relationship between intermolecular forces (hydrogen bond, dipole dipole, London dispersion forces) and the state of matter (solid, liquid gas) at room temperature?

Review
Why do some molecules form stronger intermolecular attractions than others?

Lab Cleanup
Take care of this place.

Work Time
Complete your slides and study for Monday's lab quiz.

IMF Experiment Plan

Goal:
Develop an investigation plan and describe the data that will be collected and the evidence to be derived from the data.

Agenda:
Warmup - Annotate Rubric
Start Slides
Complete Experiment Design Plan

Warmup - Annotate Rubric

Your competency is a combination of the Polarity Lab Plan and a Slides Presentation.

On the provided rubric, make a note of which slide or where in the Polarity lab plan you will show evidence of each of the criteria. You can also view the rubric here. 

Start Slides

1. Have one of your group members make a copy of this Google Slides presentation.
2. Rename the document Period-First Names IMF Lab
3. Share the document with your teammates and me (awallace@euhsd.org).
4. Complete slides 3-5 using the work you did last Friday. 

Complete Experiment Design Plan
Work with your group members to complete the experiment design plan and write a procedure to be carried out on Wednesday.

Selecting Samples for Polarity Lab

Goal:
Select appropriate samples for a polarity lab. Write a research question and hypothesis.

Agenda
Group Quiz
Brainstorm
Notes: Sample Types
Sample Selection and Research
Exit Slip

Group Quiz

1. Select one scholar in your project group to be your scribe. 
2. Scribes, open this quiz. 
3. Work with your project group to complete the quiz. Feedback will be immediately sent to your scribe. 

Brainstorm
What different substances would you be interested in comparing polarity?

Notes: Sample Types
Follow along and take notes on when to use different types of samples and why.

Sample Selection and Research
With your project groups decide on 2-4 substances that you want to test in your laboratory investigation. You can select from this list or come up with your own with my approval but you must have a reason WHY you want to compare those things. 
Once you have made your selection, complete the second part of your Polarity Plan document from yesterday for the compounds you chose. 

Exit Slip
One per group.
On the provided 1/2 sheet write: 

1. Your team member names
2. your research question
3. the compounds you selected
4. Your hypothesis predicting which one is more polar

Polarity Laboratory Techniques

Goal:
Differentiate when, why, and how to use melting point tests, boiling point tests, evaporative cooling tests, chromatography, and distillation to study different compounds. 

Agenda:Team Selection
Laboratory Techniques Research 

Team Selection
Select a team of 3 scholars. If you would rather be assigned to a group see me. Once your team is approved find a new seat (2 teams per table).

Laboratory Techniques Research

1. Have one team member make a copy of this document 
2. Rename the document Period-First Names Polarity Lab Plan
3. Share the document with your teammates and me (awallace@euhsd.org).
4. Complete the first page comparing the 5 laboratory techniques. 

Intermolecular Forces

Goal:
Construct an explanation relating the intermolecular forces of a molecule to its boiling point. 

Agenda:

Warmup

Notes

Reading and Questions

Warmup

1. On your table you have a paper labeled "water," "methanol," "acetone," and "nonane."
2. Draw the Lewis structure for your molecule. 
3. Write the dipole for each bond in your compound if applicable. 
4. Make a note of the bond polarity and rotational symmetry/asymmetry of your molecule. 
5. Determine if your molecule is polar or nonpolar. 

Notes

1. Watch this video and take notes in your table. You can partner up to do this. 
2. Create a new journal entry entitled "Intermolecular Forces."
1. Write down the 3 different intermolecular forces you learned about and their definitions.
2. Write 3 main points about intermolecular forces that you learned from the video.

Reading and Questions

1. Identify the functional group in your molecule. Using table 4.1 label it with the correct intermolecular force. 
2. Use the provided tables and graphs to answer the questions on this Google Form. You will get an email with your results after school. 

Polarity

Goal:
Categorize molecules as polar or nonpolar.

Agenda:
Warmup
Notes
Practice
Apply to Lab

Warmup
Complete this Google form using your lab results from yesterday.

Notes
Create a new journal entry entitled "Polar or Nonpolar?"
Take notes on the slides below. Your notes should include:

• Definition of polar and nonpolar bonds
• Definition of rotational symmetry
• Photo/Screenshot or recreation of Frayer model from the slides

Practice
Using the notes you just took and the simulation in class, complete this worksheet. 
We are trying a new thing where you do worksheets in Google forms so I can see your work and quickly give you feedback on what you did. Tell me how you like it. 

Apply to Lab
On your lab handout, complete the Lewis Structures and VSEPR diagrams. Draw a MOLECULE dipole on the VSEPR diagram and label if each compound is polar or nonpolar. 

Intermolecular Forces

Goal: 
Formulate descriptive questions about the molecular scale causes physical properties (melting point, boiling point, separation).  

Agenda:
Warmup
Lab Stations
Questions

Warmup
Draw the Lewis Structures and 3D models for the 4 compounds on your handout. Do not draw a 3D model for nonane.

Lab Stations
Complete the 4 lab stations. You will have 15 minutes at each station. It is VERY important to work quickly but safely. Wear safety glasses.

Questions
Answer the 3 questions on the back of your handout. Write your name at the top and turn it in to me at the end of class.
