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):

  1. 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.
  2. Dig Deeper Day:
    • Research electron orbitals
      • Quantum numbers
      • Orbital shapes
      • Sigma and Pi bonds
      • Hybrid orbitals
  3. 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

Lewis Dot Symbols

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:

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.

Keep Learning!

The videos below all include information about Lewis Dot symbols.  You are strongly encouraged to review them!
