What would you change to make your rain gauge work better?

Third grade is working on:

3-ESS2-1.


Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season.


The first step was to create a rain gauge to measure precipitation. Students followed a step by step plan on how to build an accurate rain gauge.



              






These gauges were monitored and data was recorded in weather journals.



          



The unexpected happened next: an uncommonly strong wind storm swept through western Oregon (and the Joseph Gale courtyard where the gauges had been placed to measure the precipitation.)


                                                 



Students realized they needed to engineer these rain gauges differently to withstand weather elements.

Solutions included:
Adding more rock to the bottom for weight.






Adding rock around the base for support.



Using a larger, wider container.
