# Measuring thickness of a coin in Learning how to measure – Class 6 Science Experiment

## Activity Name: Measuring thickness of a coinin Learning how to measure

### Activity Description:

In this experiment, you will measure the thickness of a coin using a stack of coins and a scale. You will also explore the limitations of using a meter scale to measure curved lengths.

### Required Items:

1. 10 one rupee coins of the same size
2. Scale or ruler
3. Textbook

### Step by Step Procedure:

1. Gather 10 one rupee coins of the same size.
2. Place the coins one upon the other, aligning them as best as possible.
3. Use a scale or ruler to measure the total thickness of the stack of coins. Note down this measurement.
4. Divide the total thickness by the number of coins (10 in this case) to calculate the thickness of one coin.

To measure the thickness of a page of your textbook:

1. Take a single page from your textbook.
2. Place the page on a flat surface.
3. Use a scale or ruler to measure the thickness of the page.

### Experiment Observations:

• Measure the total thickness of the stack of coins.
• Divide the total thickness by the number of coins to determine the thickness of one coin.
• Measure the thickness of a single page from your textbook.

### Precautions:

1. Handle the coins and the page of the textbook carefully to avoid any damage.
2. Ensure that the coins are aligned properly when stacking them.
3. Place the scale or ruler perpendicular to the coins or page to get an accurate measurement.

### Lesson Learnt from Experiment:

1. By stacking the coins and measuring the total thickness, we can determine the thickness of a single coin.
2. The experiment demonstrates the concept of measuring thickness using a scale or ruler.
3. We cannot measure curved lengths, such as the perimeter of a bucket or a tava, with a meter scale because the scale is designed to measure straight distances. Curved lengths require other measuring tools like a flexible tape measure or string to get an accurate measurement.
