Measuring rain water in Weather and Climate – Class 7 Science Experiment

Chapter Name: Weather and Climate

Activity Name: Measuring rain water in Weather and Climate

Activity Description:

Required Items:

1. 10cm wide beaker
2. Funnel (10cm wide)

Step by Step Procedure:

1. Take a 10cm wide beaker.
2. Insert a funnel with the same width into the beaker.
3. Place the apparatus in an open area where it will be exposed to rainfall.
4. Wait for the rain to fall and let the water collect through the funnel into the beaker.
5. Once the rainfall stops, carefully measure the depth of water collected in the beaker.
6. The measured depth represents the magnitude of the rainfall in centimeters.

Experiment Observations:

1. The depth of water collected in the beaker after the rainfall.

Precautions:

1. Ensure the beaker and funnel are clean and dry before starting the experiment.
2. Place the apparatus in an open area away from obstacles that could block rainfall.
3. Avoid any spillage or loss of water during the measurement process.
4. Take appropriate safety measures during adverse weather conditions.

Lesson Learnt from Experiment:

This experiment provides a hands-on approach for students to understand and quantify rainfall. By directly measuring the depth of water collected, students can relate to weather reports and forecasts, fostering a deeper understanding of weather and climate concepts.
