### Content Standard
Students will be able to explain and examine the structure, properties, and changes of matter as well as sources, uses, conservation, and changes of energy.

### Benchmark
10.3.3.2 Explain how elements are arranged in the periodic table and analyze trends among elemental properties.

### Essential Knowledge, Skills, Values, and Attitudes

#### Knowledge
- Non-polar covalent bonding involves equal sharing of electrons between atoms, common in diatomic molecules (e.g., H2, O2, Cl2).

#### Skills
- Identify non-polar covalent molecules.
- Draw dot and cross diagrams to show electron sharing.

#### Values and Attitudes
- Appreciate the role of chemical bonding in understanding matter.
- Demonstrate curiosity and active participation in science discussions.

### Learning Objectives
By the end of this lesson, students should be able to:
1. Define non-polar covalent bonding.
2. Explain how electrons are shared equally in non-polar covalent bonds.
3. Identify and draw examples of non-polar covalent molecules.

### Key Questions
- What is a non-polar covalent bond?
- Why are electrons shared in some covalent bonds?

### Materials
- Periodic table
- Whiteboard and markers
- Visual aids or poster of covalent bonding
- Dot and cross diagram handouts
- Textbook or printed notes

### Lesson Procedure

#### INTRODUCTION (5 mins)
**Teacher Activity:**
- Greet the class and engage students in a brief discussion on chemistry.
- Introduce today's topic: non-polar covalent bonding with a thought-provoking question: "Have you ever wondered how some molecules consist of identical atoms and still form bonds?"

**Student Activity:**
- Students respond and share their ideas about molecules and bonding briefly.

#### BODY (30 mins)

**MODELLING (15 mins)**
**Teacher Activity:**
- Define non-polar covalent bonds. Explain that in these bonds, electrons are shared equally between two atoms due to their similar electronegativities.
- Provide examples of non-polar covalent molecules, like hydrogen (H2), oxygen (O2), and chlorine (Cl2).
- Show diagrams for H2 and O2, highlighting the equal sharing of electrons.

*Illustration:*
- Draw the following molecular structures on the whiteboard and annotate:
- H-H (for H2)
- O=O (for O2)

**Student Activity:**
- Students take notes and observe the visual aids while asking clarifying questions if needed.

**GUIDED PRACTICE (10 mins)**
**Teacher Activity:**
- Model how to draw a dot and cross diagram for H2 and Cl2.
- Break down the drawing process step by step:
1. Represent each atom with a unique dot (•) or cross (×).
2. Show how the electrons are shared by overlapping them.

**Student Activity:**
- Students draw the diagrams with the teacher’s guidance, practicing the technique on H2 and Cl2.

**INDEPENDENT PRACTICE (5 mins)**
**Teacher Activity:**
- Distribute a worksheet with three non-polar covalent molecules (e.g., H2, O2, Cl2) for students to draw and classify.

**Student Activity:**
- Students complete the worksheet individually or in pairs.

#### CONCLUSION (5 mins)
**Teacher Activity:**
- Summarize key points about non-polar covalent bonds.
- Ask key questions:
- "What characterizes a non-polar covalent bond?"
- "Give an example of a non-polar covalent molecule."

**Student Activity:**
- Students respond and share their understanding, while clarifying any final questions they might have.

### Assessment
- Observe students during guided and independent practice for understanding.
- Review answers on the worksheet to check for comprehension.

### Reflection
- At the end of the lesson, consider what went well and areas for improvement. Note any questions or topics that may need further exploration in future lessons.
