Lesson Plan: Atomic Structure - Sub-shells and Atomic Orbitals, Electron Configurations

Subject: Chemistry Level: Cambridge Assessment International Exams - Advanced Subsidiary Level

Duration: 40 minutes

Objectives: 1. Understand the concept of sub-shells and atomic orbitals. 2. Determine the electron configuration of an atom. 3. Apply the knowledge of sub-shells and atomic orbitals to solve problems related to electron configurations.

Materials: - Whiteboard and markers - Handouts with practice questions - Computers or tablets with internet access - Projector or smartboard - Video: “Atomic Orbitals and Electron Configurations” (Link: https://www.youtube.com/watch?v=ZwvUsw3h3qU)

Introduction (5 minutes): 1. Greet the students and briefly introduce the topic of atomic structure, specifically sub-shells and atomic orbitals. 2. Engage the students by asking them to share their prior knowledge about sub-shells and atomic orbitals. 3. Write the objectives of the lesson on the board.

Main Activity (20 minutes): 1. Divide the students into pairs or small groups. 2. Distribute the handouts with practice questions related to sub-shells and atomic orbitals, as well as electron configurations. 3. Instruct the students to work together to solve the questions, discussing their reasoning and strategies. 4. Circulate around the classroom, providing assistance and guidance as needed. 5. Encourage the students to use English for communication during the activity, promoting reading, writing, listening, and speaking skills.

Video (10 minutes): 1. Introduce the video “Atomic Orbitals and Electron Configurations” to the students. 2. Play the video using a projector or smartboard. 3. Instruct the students to watch the video attentively, taking notes if necessary. 4. After the video, facilitate a brief discussion to clarify any doubts or questions that may have arisen.

Closure (5 minutes): 1. Summarize the key points covered in the lesson, emphasizing the understanding of sub-shells, atomic orbitals, and electron configurations. 2. Ask the students to reflect on their learning and share any new insights or connections they have made. 3. Provide feedback and address any misconceptions that may have emerged during the lesson. 4. Assign relevant homework or additional practice questions for reinforcement.

Differentiation Strategies: 1. Visual learners: Use diagrams, charts, and models to illustrate the concept of sub-shells and atomic orbitals. 2. Auditory learners: Engage students in discussions and encourage them to explain their reasoning verbally. 3. Kinesthetic learners: Incorporate hands-on activities, such as building atomic models or using manipulatives to represent sub-shells and atomic orbitals. 4. English language learners: Provide vocabulary support by pre-teaching key terms and offering bilingual dictionaries or glossaries. Encourage peer collaboration and provide sentence frames or sentence starters to support speaking and writing tasks.

Note: The duration of each section can be adjusted based on the pace and needs of the students.
