Rainwater Gauges from Syringes and PVC Pipes
Students built calibrated rain gauges and tracked monsoon rainfall across six villages, comparing their data with the district weather station.
Meera PatelScience Teacher · Shree Saraswati Vidya MandirDuring the monsoon unit, students built rain gauges from discarded 50 ml syringes mounted in PVC pipes with a funnel. Each gauge was calibrated against a measuring cylinder.
Six students took gauges home to six different villages and recorded rainfall daily for eight weeks. The data was pooled in a shared chart in class, plotted as bar graphs and compared with the official district readings.
The students discovered that rainfall in the hilly village was consistently higher, which led to a discussion on relief rainfall. A real dataset they collected themselves made the graphs chapter effortless.
