Shapes and area in Learning how to measure – Class 6 Science Experiment
Chapter Name: Learning how to measure
Activity Name: Shapes and area in Learning how to measure
Activity Description:
In this experiment, we will use two sheets of A4 paper cut into different shapes to determine their relative sizes. We will measure the surface area of each sheet by counting how many matchboxes of equal size are needed to cover the entire surface.
By comparing the number of matchboxes required, we can determine which sheet is bigger or smaller in size.
Required Items:
- Two sheets of A4 paper
- Scissors
- Empty matchboxes of equal size
- Notebook
Step by Step Procedure:
- Cut two sheets of A4 paper into different shapes as shown in the figure.
- Take the first sheet and place it on a flat surface.
- Start from one corner of the sheet and begin counting how many matchboxes are needed to cover the entire surface. Place each matchbox next to the other without any gaps.
- Repeat the counting process for the second sheet using the same procedure.
- Record the findings in your notebook, noting down the number of matchboxes required for each sheet.
Experiment Observations:
- Note down the number of matchboxes needed to cover the entire surface for each sheet.
- Observe which sheet requires a greater number of matchboxes.
Precautions:
- Handle scissors carefully to avoid any accidents or injuries.
- Ensure the sheets of paper and matchboxes are placed on a flat surface for accurate measurements.
- Count the matchboxes accurately without skipping or overlapping any areas.
Lesson Learnt from Experiment:
Through this experiment, we learn that by measuring the surface area of an object using a standard unit (in this case, matchboxes), we can determine its relative size.
The sheet that requires more matchboxes to cover its surface is considered bigger in size, while the one requiring fewer matchboxes is smaller. Measuring the area helps us make accurate comparisons and decisions about the size of objects.
