It looks like you've uploaded a worksheet titled
"Absorbent Materials Investigation", which is designed for students to test various materials to determine whether they are
absorbent or
non-absorbent using a pipette and water.
🔍 Objective:
To investigate whether common materials absorb water by conducting a simple experiment.

🧪 Materials Listed (from the image):
1. Cotton wool
2. Fabric
3. Newspaper
4. Sponge
5. One unknown material (marked with a question mark — likely intended to be filled in by the student)
Each material has a column asking:
"Is it absorbent? Yes/No"
---
✔ Expected Answers Based on Scientific Knowledge:
| Material | Is it absorbent? | Explanation |
|----------------|------------------|-----------|
|
Cotton wool |
Yes | Cotton wool is highly absorbent due to its fibrous structure, which holds water through capillary action. |
|
Fabric |
Yes | Most fabrics (especially cotton or linen) absorb water because of their porous fibers. Synthetic fabrics may vary, but generally, fabric is considered absorbent. |
|
Newspaper |
Yes | Paper is made from cellulose fibers that readily absorb water, causing it to become soggy. |
|
Sponge |
Yes | Sponges are specifically designed to absorb liquids; they have many tiny pores that trap water. |
|
? (Unknown) | Depends | This could be something like plastic, metal, or glass — typically non-absorbent. Students would need to test it. But if left blank, it’s likely meant to be discovered during the experiment. |
> 💡 Note: The "unknown" material might be included to encourage hypothesis testing and observation.

🛠️ How to Conduct the Investigation:
1. Use a
pipette to drop water onto each material.
2. Observe what happens:
- Does the material soak up the water?
- Does the water bead up and roll off?
- Does the material change color or feel wet?
3. Record observations in the table.

📝 Example Completed Table:
| Material | Is it absorbent? |
|----------------|------------------|
| Cotton wool | Yes |
| Fabric | Yes |
| Newspaper | Yes |
| Sponge | Yes |
| Plastic (e.g.) | No |
*(Note: The last one depends on what the "?" represents. If it's something like plastic wrap or a rubber sheet, it would be non-absorbent.)*
---
🎯 Learning Outcome:
Students learn about
material properties, specifically
absorbency, and how different materials interact with water. This supports science skills like prediction, observation, and classification.

✔ Final Answer Summary:
-
Cotton wool: Absorbent
✔
-
Fabric: Absorbent
✔
-
Newspaper: Absorbent
✔
-
Sponge: Absorbent
✔
-
Unknown material: Needs testing — likely non-absorbent if it's plastic, metal, etc.
