CCELA Alignment - Lesson 4.6

Represent Bonding with Lewis Dot Diagrams

Reading Standards for Literacy in Science and Technical Subjects 6-8

  • LITERACY.RST.6-8.4
    Determine the meaning of symbols, key terms and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 6-8 texts and topics.
  • LITERACY.RST.6-8.7
    Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table).

Students use the Activity Sheet to read about Lewis Dot diagrams for representing atoms and molecules. Students compare Lewis Dot structures with energy level models to see the similarities and differences. Students also read about ways to show covalent and ionic bonding using Lewis Dot structures. Students also integrate information from text with molecular models to improve their understanding.

Writing Standards for Literacy in Science and Technical Subjects 6-8

    Write arguments focused on discipline-specific content
    1. Introduce claim(s) about a topic or issue, acknowledge and distinguish the claim (s) from alternate or opposing claims, and organize the reasons and evidence logically.
    2. Support claim(s) with logical reasoning and relevant accurate data and evidence that demonstrate an understanding of the topic or text using credible sources.
    3. Use words, phrases, and clauses to create cohesion and clarify the relationship among claim(s), counterclaims, reasons, and evidence.
    4. Establish and maintain a formal style.
    5. Provide a concluding statement or section that follows from and supports the argument presented.

Students use the Activity Sheet to write answers to questions about the different components of Lewis Dot structures and what they represent.
