Lesson Plan: Atomic Structure - Periodic Patterns of Atomic and Ionic Radii, Patterns in Ionization Energies in the Periodic Table

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

Duration: 40 minutes

Objectives: 1. Understand the concept of atomic and ionic radii and their periodic patterns. 2. Analyze the patterns in ionization energies in the Periodic Table. 3. Develop English language skills in reading, writing, listening, and speaking. 4. Implement differentiation strategies to cater to the diverse needs of students.

Materials: - Whiteboard and markers - Handouts with periodic table and related questions - Computers or tablets with internet access - Projector or smartboard - Video: “Periodic Table Trends Explained” (https://www.youtube.com/watch?v=0RRVV4Diomg)


Introduction (5 minutes): 1. Greet the students and introduce the topic of atomic structure, specifically focusing on periodic patterns of atomic and ionic radii and patterns in ionization energies. 2. Engage students in a brief discussion about their prior knowledge of the Periodic Table and its elements.

Main Activity (20 minutes): 1. Divide the students into pairs or small groups. 2. Provide each group with a handout containing a periodic table and related questions. 3. Instruct the students to analyze the periodic table and answer the questions related to atomic and ionic radii and ionization energies. 4. Encourage students to discuss their findings within their groups and support their answers with reasoning. 5. Circulate among the groups, providing guidance and clarification as needed. 6. After the allotted time, bring the class together for a whole-group discussion, allowing each group to share their findings and explanations.

Video (10 minutes): 1. Introduce the video “Periodic Table Trends Explained” and explain its relevance to the topic. 2. Play the video, ensuring that all students can see and hear it clearly. 3. Encourage students to take notes during the video to aid their understanding. 4. After the video, facilitate a brief discussion to address any questions or clarifications.

English Language Integration (5 minutes): 1. Assign a short reading passage related to atomic and ionic radii or ionization energies. 2. Instruct students to read the passage individually and underline any unfamiliar vocabulary. 3. Pair up students with different underlined words and ask them to explain the meanings to each other. 4. Encourage students to use the new vocabulary in sentences or short paragraphs, promoting writing and speaking skills.

Closure (5 minutes): 1. Summarize the main points discussed during the lesson, emphasizing the periodic patterns of atomic and ionic radii and patterns in ionization energies. 2. Allow students to ask any remaining questions or seek clarification on the topic. 3. Provide a brief preview of the next lesson to create continuity and anticipation.

Differentiation Strategies: 1. For students with lower English proficiency, provide simplified handouts or additional visual aids to support their understanding. 2. Offer extra challenges or extension activities for advanced students, such as analyzing more complex elements or researching real-life applications of atomic and ionic radii. 3. Encourage collaborative learning by pairing students with different language abilities, allowing them to support and learn from each other. 4. Provide additional resources, such as online articles or interactive simulations, for students who prefer alternative learning methods.

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