Monday, November 25, 2019: With the short holiday week, students who needed time to work on the Yellowstone Virtual Road Trip work from last week had the opportunity to do so; students who were caught up watched The Lost Worlds of Planet Earth from Season 1 of Cosmos.
Tuesday, November 26, 2019: Class began with a self-assessment with regard to work completed for the Yellowstone Virtual Road Trip project. Students evaluated their work via a checklist, turned in the checklist for assignment credit, and then received back the checklist in order to complete missing work. Students who needed time to work had the opportunity to do so; students who were caught up watched The World Set Free from Season 1 of Cosmos.
Pre-Lab: Read the Lesson 34 Worksheet and then complete the Ester Synthesis Lab Safety Survey before class on Monday.
Lesson 34 Lab: Our work today is to conduce the Ester Synthesis Lab. Class will begin with a class discussion of the experiment, with emphasis placed on lab safety. For the lab, students will use the Lesson 34 Student Worksheet to guide them through the lab.
Lab Instructions on whiteboard:
Ester synthesis mechanism (Fischer esterification):
Acid-catalyzed ester hydrolysis:

- Write notes for Lesson 34 and work through the practice problems at the end of Lesson 34.
- Please ask questions about anything from Lesson 34 you do not yet fully understand.
We began class with students watching the video below (except for 5th period which lost half of the class due to Pep Assembly prep):
After the video, students copied the notes from the whiteboard pictured below to their notebooks. (Although we did not use it today, the Lesson 33 PowerPoint is provided here as a learning resource.)
Students then gathered into Functional Group project teams and began working on the Functional Group Project. Students will have the full class period tomorrow and then may also work on Monday and Tuesday if needed while students who are finished are treated to Hunting the Elements. The posters will be utilized by the class during the Chapter 6 test.

Fall SLCs are scheduled for Tuesday, November 26 from 3:00-7:00 PM and Wednesday, November 27 from 8:00-11:00 AM. Students will complete the SLC Template for each class (available in English, Spanish, and Vietnamese), excluding Advisory. Students who need guidance will out the SLC Template can use the SLC Handout Exemplar for inspiration. Finally, our Video Productions class created a helpful how-to video so students understand the expectations around leading an SLC.
Students who are able to communicate in a language other than English should sign up to take the World Language Credit by Proficiency test. Students can earn up to 4 high school credits based on their level of proficiency.
We continued our study of Lewis Dot Structures by investigating the Octet Rule through the lens of double and triple bonds. Students applied the HONC 1234 rule with their understanding of valence electrons (octet = eight electrons) to build molecules that share one or more bonds. We worked through the Lesson 32 PowerPoint and then students used the Lewis Dot puzzle pieces from Lesson 31 to work through the Lesson 32 worksheet.

With a number of students out of school for the day on an AVID field trip, class today focused on reviewing the types of bonds formed between atoms, and extending into modeling electrons using Lewis Structures.
For our entry task today, students were asked to take a brief survey about science electives they are interested in taking next school year. Students may click this survey link or use the QR code below:
After the entry task, students have the following options (must turn in something today to receive credit for class – an assignment, a shared document, or an email with notes is sufficient):
- Catch-up Day:
- Complete and turn in worksheets for Lessons 28-30
- Turn in or revise Unit 1 Project*
- Turn in or revise Electroplating Lab Report*
- *Amnesty Day today = 80% max credit. After today, 60% max credit. After Friday, no credit.
- Dig Deeper Day:
- Research electron orbitals
- Quantum numbers
- Orbital shapes
- Sigma and Pi bonds
- Hybrid orbitals
- Get Ahead Day:
- Complete SLC Reflection Worksheet
- Research Electronegativity Scales
- Research Functional Groups
- Research / Build molecules with MolView
- Watch the videos below, then read Lesson 31 and complete the exercises
Agenda for today:
To accommodate students who missed class yesterday because of the field trip, we had a two-pronged Entry Task. Students who missed yesterday were directed to quickly take the Science Elective Survey. Students who completed the survey (and those who finish in time today) were directed to complete the alternate entry task. Resources for both are provided below:
Science Elective Survey (or use the QR code)Alternate Entry Task:
We extended our learning of the HONC 1234 rule from Friday by introducing the concept of Lewis Dot Symbols and Structures. To solve the alternate entry task, students were reminded about how the HONC 1234 rule connects the concepts of valence electrons to the number of bonds each atom can make:
We used that understanding to solve the Lewis Dot Structures for the entry task:
Next, we worked through the Lesson 31 PowerPoint, writing down key vocabulary and reviewing Lewis Dot Symbols and how they assemble to create Lewis Dot Structures in our class notes. Students had the remainder of the class period to work in groups of four on the Lesson 31 Worksheet using the Lewis Dot Puzzle Pieces.
The videos below all include information about Lewis Dot symbols. You are strongly encouraged to review them!
