You're absolutely right — this is a science activity about
absorption, specifically
water absorption. The goal is to identify which objects absorb water and which do not.

##
✔ Solution Summary:
🟢 Water Absorbent Objects (Color these):
-
Paper
-
Handkerchief
-
Towel
🔴 Non-water Absorbent Objects (Do NOT color these):
-
Marble
-
Plastic toy
-
Paper clip
---
## 🧪 Explanation:
Absorption means the ability of a material to take in or soak up a liquid (in this case, water) into its structure.
Let’s go through each object:
---
📄 1. Paper
- Made from plant fibers (like wood pulp), which are porous.
- These tiny pores let water seep in and get trapped →
absorbs water.
✔ So,
color it.
---
🎱 2. Marble
- A hard, smooth stone made mostly of calcium carbonate.
- Has no pores; water just beads up or runs off →
does NOT absorb water.
✘ Do
not color it.
---
🧵 3. Handkerchief
- Usually made of cotton or other natural fibers.
- Fibers have spaces between them that trap water →
absorbs water well.
✔ So,
color it.
---
🧸 4. Plastic toy
- Made of synthetic polymers with tightly packed molecules.
- No pores → water cannot enter →
non-absorbent.
✘ Do
not color it.
---
📎 5. Paper clip
- Made of metal (usually steel).
- Metal is non-porous and repels water →
does NOT absorb water.
✘ Do
not color it.
---
🧼 6. Towel
- Designed to absorb water! Made of looped cotton or microfiber.
- Excellent at soaking up liquids →
highly absorbent.
✔ So,
color it.

## 📊 Final Classification (as shown in your diagram):
| Water Absorbent | Non-water Absorbent |
|------------------------|--------------------------|
| 1. Paper | 1. Marble |
| 2. Handkerchief | 2. Plastic toy |
| 3. Towel | 3. Paper clip |

## 🖍️ Coloring Instructions:
On the worksheet, you should
color the circles around:
- Paper
- Handkerchief
- Towel
*(The image already shows these circled in yellow — so you’re done if you colored those!)*

## 💡 Science Tip:
This concept is important in everyday life — for example:
- Towels dry you because they absorb water.
- Raincoats are made of waterproof materials (non-absorbent) to keep you dry.
- Paper towels are used to clean spills because they absorb liquids.
