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

  1. Define Radioactivity: Explain the concept of radioactivity and differentiate between its various radiation types (alpha, beta, gamma).

  2. Recognize Historical Contributions: Understand the historical development of radioactivity research, emphasizing Marie Curie's role.

  3. Identify Radiation Characteristics: Describe the distinct properties and effects of alpha, beta+, beta-, and gamma radiation.

  4. Apply Knowledge Practically: Demonstrate understanding of radiation through interactive Phet Colorado simulations and handbook exercises.

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.

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.

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.
