Students will create their own rain gauge using household items to monitor rainfall over a period of time. They will record daily precipitation levels, analyze the data, and discuss how rain affects their local environment.
If it rains heavily, then the rain gauge will collect more water compared to lighter rainfall days.

Cut the top of the plastic bottle and invert it into the bottom part to create a funnel.
Use rocks to stabilize the bottle's base.
Mark the side of the bottle with equally spaced measurement lines using a ruler and marker.
Place the rain gauge in an open area away from obstructions.
After it rains, measure the water level in the gauge and record it daily in the notebook.
Empty the gauge after each measurement.
Continue to check and record precipitation over 10 days.
Analyze any patterns or trends from the data collected.
The rain gauge will accurately measure variations in daily rainfall, providing insights into local weather patterns and helping understand precipitation's impact.

Be careful when using scissors and ensure the rain gauge is placed in a safe, stable location.
Use charts to show daily rainfall data collected.
Include photos of the rain gauge throughout the project.
Explain the importance of rainfall measurement in understanding climate and agriculture.
It's a simple, cost-effective way to measure rain and easy to set up and read.
Consider extending the observation period or use simulated rainfall to test the gauge.
Adding rocks or pebbles to the base provides stability against wind.
