Thread Method

Thread is useful for measuring curved objects because it can follow curved surfaces easily.

🔬 Measurement Activities

🪙

Activity 1: Measuring circumference of a coin

A thread is wrapped around the edge of the coin and marked. The thread is straightened and measured.

This gives the circumference of the coin.

🪙🪙🪙

Activity 2: Finding thickness of a coin

Ten identical coins are stacked and total height is measured.

Thickness of one coin = Total height ÷ 10. This gives a more accurate value.

🧵

Activity 3: Finding diameter of a wire

Wire is wound around a pencil. Length is measured and divided by number of turns.

Diameter of wire = Total length of wound wire ÷ Number of turns.

☕

Activity 4: Measuring length of a curved handle

A thread is placed along the curved handle of a cup and marked. The thread is then straightened and measured with a ruler.

This gives the length of the curved handle.

5. Wire diameter is found using: Scale directly Winding method Drawing Guessing

6. Wire is wound around: Book Pencil Coin Table

7. Curved handle is measured using: Scale only Thread Divider Compass

8. These methods are: Direct Indirect Rough Wrong

9. Multiple measurements give: Less accuracy More accuracy No change Wrong value

10. These activities improve: Drawing Measurement skill Writing Guessing

🧠 HOTS Questions

Click each question to reveal the answer.

1. Why is thread better than ruler for curved objects?

Because thread can follow curved surfaces easily.

2. Why does stacking coins give accurate thickness?

Because error reduces when measuring many coins together.

3. Why is wire wound multiple times?

To increase accuracy by averaging measurement.

4. Can we measure curved objects directly with ruler?

No, because ruler measures straight length only.

5. Why are indirect methods useful?

They help measure very small or curved objects accurately.
