Chapter Name: Water in our life
Activity Name: How much water do we waste? in Water in our life
The experiment aims to measure the amount of water wasted while washing hands and feet under a tap. By collecting the water in a bucket and comparing it to the individual usage, students can understand the importance of water conservation.
The activity also encourages students to identify situations in daily life where water is wasted and suggest ways to avoid such wastage.
- Tap with running water
- Stopwatch or timer
Step by Step Procedure:
- Select a group of students from the class to participate in the experiment.
- Choose a tap with running water for the activity.
- Have one student volunteer to wash their hands and feet under the tap.
- Use a stopwatch or timer to measure the time it takes for the student to complete the wash.
- Record the time taken by the student.
- Now, place a bucket under the tap, ensuring it can collect water at the same flow rate as the tap.
- Open the tap for the same duration as the recorded time from step 5.
- Collect the water in the bucket.
- Measure the volume of water collected in the bucket using a measuring container.
- Calculate the amount of water wasted by subtracting the collected water volume from the volume used by the student.
- Repeat the experiment with other students from the group and record their individual results.
- Note down the time taken by each student to wash their hands and feet under the tap.
- Measure the volume of water collected in the bucket for each student.
- Calculate the amount of water wasted for each student by subtracting the collected volume from the volume used by the student.
- Record the observations in a tabular format, including the names of the students, time taken, volume used, and water wasted.
- Ensure the bucket is placed properly under the tap to collect all the water without spillage.
- Make sure the flow rate of water from the tap remains constant during the experiment.
- Use a stopwatch or timer accurately to measure the time taken by the students.
- Take appropriate safety measures to prevent slipping or accidents while washing hands and feet.
Lesson Learnt from Experiment:
The experiment helps students understand the amount of water wasted when using a tap for washing hands and feet. By comparing the volume of water collected in a bucket to the individual usage, students can visualize the significance of water conservation.
They will learn that a considerable amount of water can be saved by using alternative methods like using a bucket instead of letting the tap run continuously.
This activity also prompts students to think about other situations where water is wasted and encourages them to suggest ways to avoid such wastage.
