Nuclear medicine
👩 Teacher’s Guide
🎯 Objective
Students will be able to:
- Understand the basic ideas of nuclear medicine
- Use correct science vocabulary
- Explain real-world uses and safety issues
📝 Teaching Notes
- Key idea to emphasize: For scans and cancer treatment.
- Common misconception: All radiation is man-made (many sources are natural).
- Suggested teaching approach:
- Use simple diagrams and analogies
- Connect to medicine, energy, and everyday life
- Keep explanations age-appropriate and clear
💬 Discussion Starter
Ask students:
- Why do atoms have different isotopes?
- How can radiation be both useful and dangerous?
🧒 Student Worksheet
Concept and Helping Material

Hands-On Experiment or Activities
Activity 1: Coin half-life model
What You Need: 30 coins
What You Do: Toss coins, remove heads each round, record remaining.
Think and Talk: What changed? What stayed the same?
Activity 2: Radiation shielding demo (safe simulation)
What You Need: flashlight, paper, cardboard, thick book
What You Do: Shine light through materials to model penetration differences.
Think and Talk: What changed? What stayed the same?
