Rainfall Activities
Investigate the way rainfall accumulates during a long period of rain as a warm front moves across the area, by checking the rainfall every 30 minutes or so. Contrast this with rainfall rates in shorter-lived showers.

How big are raindrops? Collect them on coloured blotting paper, quickly measure their sizes. Calibrate the blotting paper by dropping water drops of known size/volume onto it. How different is the size distribution of raindrops in showers compared to that in drizze?

Projects using Rainfall
Look at the sheltering effect of trees and buildings by putting down a network of simple rain collectors (e.g.jam jars) and measuring the accumulated volume in each after a shower or longer period of rain. Relate the result to wind speed and direction.
