Sorting recyclable materials into the correct bins: Plastic, Metal, Glass, and Paper.

This is a material sorting activity designed to help learners identify and categorize everyday objects based on the primary material they are made from.

---

🧩 Goal:

Sort each object at the bottom into one of the four recycling bins labeled:
- Plastic
- Metal
- Glass
- Paper

Each bin has 4 slots, and there are exactly 16 objects — so 4 objects go into each bin.

---

## ✔ Step-by-Step Solution & Explanation

Let’s go through each object and assign it to the correct material category.

---

🟦 PLASTIC Bin (4 items)

1. Plastic bottle with pump – Clearly plastic (like a soap or lotion dispenser).
2. Plastic water bottle – Standard PET plastic bottle.
3. Plastic cup – Disposable plastic cup (often used for drinks).
4. Plastic bag – Crumpled plastic shopping or trash bag.

> 💡 *Note: Some may argue the “plastic cup” could be paper with plastic lining — but in educational contexts like this, it’s typically categorized as “plastic” if it’s shiny, flexible, and non-recyclable as paper.*

---

🟨 METAL Bin (4 items)

1. Aluminum can – Soda or food can (metal).
2. Bottle cap – Metal screw-on cap (common on glass bottles).
3. Canned food – Opened metal can.
4. Metal lid or jar ring – The ring part of a mason jar or similar.

> 💡 *The small circular item next to the can looks like a metal lid or seal — definitely metal.*

---

🟩 GLASS Bin (4 items)

1. Wine glass – Stemmed drinking glass — clearly glass.
2. Drinking glass / tumbler – Simple glass tumbler.
3. Glass bottle – Like a wine or juice bottle.
4. Broken glass shard – Representing broken glass (still glass material).

> 💡 *Even though broken, it’s still categorized as glass for recycling/safety purposes.*

---

🟫 PAPER Bin (4 items)

1. Newspaper – Folded newspaper.
2. Cardboard box – Small open box (cardboard is processed paper).
3. Crumpled paper – Generic waste paper.
4. Paper towel or napkin – Rolled or folded paper product.

> 💡 *Cardboard and paper towels are both paper-based materials, even if they’re not “paper” in the strictest sense — they belong in the paper recycling category in most systems.*
