LP3 - Intro Radioactivity - Higher Secondary Level

Lesson: Physics, Radioactivity and Radiation introduction

Audience & Context

Class/Course	Physics
Teacher Name	Created by Tom Beyen (RHIZO 1) & Joos Van Cauwenberghe (RHIZO 1)
Audience	Secondary school, fith year (students are 16 - 17 old)

Lessons Topics

Basic Concepts of Radioactivity: Understanding radioactivity and its types - alpha, beta+, beta-, and gamma radiation. Historical Insights: Exploring the discovery of radioactivity with a focus on Marie Curie's contributions. Radiation Types in Detail: Examining the properties and effects of alpha, beta+, beta-, and gamma radiation.

Learning Objectives

Define Radioactivity: Explain the concept of radioactivity and differentiate between its various radiation types (alpha, beta, gamma). Recognize Historical Contributions: Understand the historical development of radioactivity research, emphasizing Marie Curie's role. Identify Radiation Characteristics: Describe the distinct properties and effects of alpha, beta+, beta-, and gamma radiation. Apply Knowledge Practically: Demonstrate understanding of radiation through interactive Phet Colorado simulations and handbook exercises.

Flow	Timing	Description	Support Tools & Resources
OPEN
Hook/ Icebreaker/ Recap	5 min	Share a trivia question about radioactivity to engage students. Ask, "Who discovered radioactivity?" (Anticipated answer: Henri Becquerel, but leading to Marie Curie).	Poll via Zoom
Agenda	2 min	Outline the lesson's agenda: History of the scientific field of radioactivity. Different radiation types, interactive demo, individual Kanban exercises, closing with a Kahoot quiz.	Google slides
PROCESS
Activate	5 min	Internet search Ask students to briefly research and share one fact about Marie Curie in the chat.	Zoom chat
Content	10 min	Field of radioactivity Presentation of a brief history of radioactivity. Introduce the different types of radiation: alpha, beta+, beta-, and gamma using online Phet Colorado animation.	Google Slides Phet Colorado animations. Youtube video (from min 1 - min 3): https://www.youtube.com/watch?v=M0uw4ZNpqcI
Individual Work	15 min	Guide students to use Phet Colorado interactive demos to explore different radiation types. Encourage them to experiment with variables and observe effects. Conduct exercises 1 - 5, p 168. Link solutions (pre-recorded videos in chat). Link to the mural with individual Kanban boards. Students update their individual Kanban boards (To Do, Doing, Stuck, Done) based on their progress and learning. Facilitate peer Q&A in breakout rooms for those 'stuck'.	Phet Colorado Handbook Loom: Pre-recorded solution videos. Mural with Kanban board (to do, doing, stuck, done). One breakout room 'peer Q&A'.
CLOSE
Summary	3 min	Summarize key points of the lesson: Marie Curie's role in discovering radioactivity, types of radiation, and findings from the Phet simulations.	Recap Google Slides
Next Steps	1 min	Inform students about the next lesson's focus and any preparatory work or reading required.	Google Slides
Exit Ticket		Conclude with a short Kahoot quiz to assess understanding of the day's topics.	Kahoot link in zoom chat

Additional Notes:

• Ensure to regularly engage with students via Zoom, encouraging questions and discussions.

• Monitor Miro/Mural Kanban boards to track student progress and intervene when necessary.

• Use the breakout room feature effectively for peer learning and to address specific queries.

• Follow up with a summary email including key points and resources from the lesson.
