👩 Teacher’s Guide
🎯 Objective
Students will be able to:
- Understand the basic ideas of fusion
- Use correct science vocabulary
- Explain real-world uses and safety issues
---
📝 Teaching Notes
- Key idea to emphasize: Joining small nuclei together.
- 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?
