Activity Name: Measuring Lengths in Learning how to measure
The experiment involves measuring the length of one side of a table using hand-spans. Students will record the length of the table in terms of the number of hand-spans.
- Students’ hands
Step by Step Procedure:
- Each student will measure the length of one side of the table using their hand-span.
- Record the name of each student and the number of hand-spans they used to measure the table in the provided table.
|S.No||Name of Student||Number of Hand-Spans|
- Ensure that students measure from the same starting point to maintain consistency.
- Encourage students to use their hand-span consistently and not vary their technique.
Lesson Learnt from Experiment:
The experiment aims to determine whether all students obtain the same number of hand-spans when measuring the length of the table. Based on the observations, analyze the results and draw conclusions:
- Do all of you get the same number of hand-spans for the length of the table?
- Analyze the recorded data and determine if all students obtained the same number of hand-spans.
- Who got more number of hand-spans?
- Identify the student(s) who measured the table using a greater number of hand-spans compared to others.
- Why is there a difference in the number of hand-spans, even though you measured the same table?
- Discuss possible reasons for the variations in measurements, such as differences in hand sizes, hand placement, or individual measurement techniques.
By conducting this experiment, students will understand that variations in measurements can occur due to individual differences and measurement techniques. It highlights the importance of standardization and precision when measuring objects.
