🧮♻️ Waste Challenge: A Math & STEAM-Based Game 🌍🗑️

💡 Concept:

Students (16 years old) become waste reduction strategists, challenged to redesign the way we deal with waste in homes, schools, and communities. Using math (percentages, comparisons, data analysis) and STEAM tools (design thinking, modeling, and innovation), teams will tackle how much we throw away, and how to reduce it in creative, measurable ways.

🕹 Game Setup & Rules

📌 Teams: Groups of 4–5 students
📌 Objective: Design the smartest, most measurable waste-reduction plan
📌 Time Limit: 60–90 minutes
📌 Winning Criteria: Highest points for accuracy, creativity, and data-supported impact

🔹 Round 1: Waste Audit (Percentages & Volume Calculation) 📊🗃️

💬 Challenge: What types of waste do we produce most?

✅ Task: Analyze fictional waste bin data from a school or home (e.g., food scraps, plastic wrappers, paper, electronics)

➤ Goal:

• Calculate percentage of total waste by category
  
  
• Identify the most common waste types and their environmental impact
  
  

🎯 Points for: Accurate math, waste sorting logic, and clear findings

🔹 Round 2: Waste-Free Alternatives Plan (Ratios & Budgeting) 🧺📉

💬 Challenge: How can we swap wasteful products for better options?

✅ Task: Propose low-waste swaps (e.g., reusable bottles, bulk food, digital notes) and calculate the ratio of waste reduced per week or month

➤ Goal:

• Apply ratios to show reduction over time
  
  
• Include rough cost comparisons or savings if possible
  
  

🎯 Points for: Feasible swaps, math logic, and daily life relevance

🔹 Round 3: Visualizing Waste Reduction (Graphs & Comparisons) 📈♻️

💬 Challenge: How much waste can one person—or a class—save?

✅ Task: Create bar or pie charts showing waste before and after using sustainable habits (e.g., lunchbox redesign, classroom bin changes)

➤ Goal:

• Use fictional data to show clear improvement
  
  
• Include real units: kg of food, # of bottles, paper sheets, etc.
  
  

🎯 Points for: Data accuracy, strong visuals, and clarity of comparison

🔹 Round 4: Zero Waste Innovation Pitch (STEAM Design & Creativity) 🎤🔧

💬 Challenge: What tool, system, or campaign could help people waste less?

✅ Task: Invent a product, service, or awareness campaign (e.g., “Refill Buddy” app, DIY recycling station, locker lunch audit kit)

➤ Goal:

• Sketch a prototype or make a storyboard
  
  
• Support your pitch with simple math: how much waste it prevents or saves
  
  

🎯 Points for: Creativity, clarity, and use of math and STEAM thinking

🏆 Final Scoring & Winner Announcement 🎉

• Teams total their scores
  
  
• Winning team earns the title of “Zero Waste Champions”
  
  
• Wrap up with a class reflection: “What’s one thing we could change this week to waste less?”
