Challenge: Review and Practice [∞]

Day 4 – Review and Practice

---

Objective

Consolidate understanding of nuclear processes, binding energy, and their relationship to element formation through engaging review activities and creative synthesis.

---

10-Minute Launch

Video (5 Minutes)

• Show a brief video (e.g., "Nuclear Reactions Explained" or "How Stars Create Elements") highlighting:
  • The connections between binding energy, fusion, and element formation.
  • Key nuclear processes reviewed in earlier sessions.

Socratic Questions (A/B)

• A: Why is binding energy critical in determining whether a nuclear reaction releases or absorbs energy?
• B: How does the periodic table reflect the processes of fusion and nuclear reactions?
• A: If you could only study one type of nuclear process (fusion or fission), which would you choose and why?
• B: How do nuclear reactions contribute to the existence of life on Earth?

90-Minute Challenge

1. Group Quiz: Nuclear Reaction Scenarios (20 Minutes)

• Activity: Groups solve nuclear reaction scenarios presented as quiz questions.
  • Example questions:
    1. What happens when a star fuses hydrogen into helium?
    2. Which reaction releases more energy: fission of uranium-235 or fusion of deuterium and tritium?
    3. How does the binding energy curve explain why heavier elements are formed in supernovae?
• Format:
  • Teams receive points for correct answers.
  • Include bonus questions that require reasoning (e.g., predict the byproducts of a given reaction).

2. Interactive Periodic Table Activity: Linking Fusion to Element Formation (30 Minutes)

• Activity:
  • Groups use a large periodic table or online tool to trace the formation of elements via nuclear fusion.
  • Highlight key pathways, such as:
    • Hydrogen to helium.
    • Carbon and oxygen formation in stars.
    • Heavier elements created during supernovae.
• Deliverable:
  • Groups create a visual or written explanation of how fusion builds up the periodic table.

3. Display: Concept Map Summarizing Nuclear Reactions (40 Minutes)

• Activity:
  • Groups create a concept map that connects:
    • Fission, fusion, and radioactive decay.
    • Binding energy and stability.
    • Element formation and energy release.
• Instructions:
  • Use markers, sticky notes, or digital tools.
  • Include diagrams of example reactions and annotated binding energy curves.
• Variation Options:
  1. Group 1: Focus on fusion and stellar nucleosynthesis.
  2. Group 2: Focus on fission and energy applications.
  3. Group 3: Focus on radioactive decay and dating techniques.
  4. Group 4: Highlight environmental and societal impacts of nuclear energy.
  5. Group 5: Draw connections between nuclear reactions and the Big Bang.
