🔥 Action Challenge: The Power of Chemistry!

Materials w1.d1 [∞]

  1. Peroxide
  2. Dish soap
  3. Yeast
  4. Coveralls
  5. Warm-hot water
  6. Water bottles or others.

📽️ Step 1: Introduction Video (3-5 min)

🎥 Title: Chemistry in Action – The Science Behind Explosions! [1]

📌 Contents:

  • What is a Chemical Reaction? (Simple explanation: Atoms rearrange to make new substances!)
  • How Chemistry Powers Everyday Life:
    • Soap cleans grease ✨
    • Batteries create electricity ⚡
    • Baking soda makes cakes rise 🍰
  • The Foam Frenzy Reaction! (Preview of ingredients and a quick teaser of the reaction!) [2]

💡 Engaging Hook:

  • Show a fast-motion clip of foam erupting.
  • Ask: Can you figure out why this happens?
  • Get ready to compete in the ultimate chemistry challenge!

💡 Step 2: Socratic A/B Discussion (5-7 min)

🤔 Before the challenge, let’s think like scientists!

  1. A/B Question 1: How Do We Make It Better?
    • A: The reaction is already set; we can’t control much.
    • B: We can change things like temperature, mixing speed, or ratios to get a better reaction!
    • Follow-up: Which one do you agree with? Why?
  2. A/B Question 2: Should We Prioritize Size or Speed?
    • A: A bigger foam explosion is best.
    • B: A faster eruption is better.
    • Follow-up: Which would make the reaction more exciting?
  3. A/B Question 3: Why Does Dish Soap Matter?
    • A: It helps break down the yeast.
    • B: It traps gas and makes bubbles.
    • Follow-up: What happens if we leave it out?

🔍 Key Takeaway: Every part of the reaction has a purpose! Now, let’s test it out!

🧪 Step 3: Foam Frenzy Challenge!

🏆 Mission:

Harness the power of chemistry to create the most spectacular foam eruption!

🎯 Challenge Rules:

✅ Identical materials for each team:

  • Hydrogen peroxide (fuel for reaction)
  • Yeast (catalyst)
  • Dish soap (bubble trap)
  • Food coloring (color boost)

🚀 Goal: Create the biggest, fastest, and most colorful foam explosion!

🕐 You have 5 minutes to prepare, mix, and react!

🏅 Scoring Criteria:

1️⃣ Biggest Foam Explosion – Height and volume!

2️⃣ Most Vibrant Color – Bold, creative, and eye-catching!

3️⃣ Fastest Reaction – How quickly does it erupt?

💡 Bonus Challenges (Optional):

🔥 Color Code: Teams must match an assigned color!

⏱️ Timed Reaction: Eruption must happen within a set time frame!

🧠 Step 4: Acton Mindset – Iterate & Improve!

💭 Reflection Questions:

  • What worked best in your reaction?
  • What would you change if you did it again?
  • How does this reaction compare to real-world chemistry, like baking or cleaning?

💡 Final Thought: Science is about testing, adjusting, and learning—just like this challenge!

🎉 Ready? Let the Foam Frenzy begin! 🚀🔥


Basic Recipe Ingredients:

  • ½ cup (120 mL) hydrogen peroxide (H₂O₂) – 6% or 12% (Higher concentrations create bigger reactions.)
  • 1 packet (or 1 tbsp) dry yeast
  • 3 tbsp warm water (activates the yeast)
  • A few drops of dish soap (helps trap oxygen in bubbles)
  • Food coloring (for a colorful foam eruption)
  • A tall container (like a soda bottle or beaker)

Instructions:

  1. Prepare the Yeast Catalyst
    • In a small cup, mix 1 tbsp yeast with 3 tbsp warm water.
    • Stir well and let it sit for about 1 minute to activate.
  2. Set Up the Reaction
    • In the tall container, pour ½ cup hydrogen peroxide.
    • Add a few drops of dish soap and swirl to mix.
    • (Optional) Add food coloring to make it more vibrant.
  3. Start the Reaction! 🚀
    • Quickly pour the yeast mixture into the hydrogen peroxide.
    • Step back and watch the foamy eruption!

How It Works:

  • Hydrogen peroxide naturally breaks down into water and oxygen.
  • Yeast contains catalase, an enzyme that speeds up this reaction.
  • The oxygen gets trapped in soap bubbles, creating the expanding foam!
