Data Visualization

According to VA SOL 2.6:
The student will investigate and understand basic types, changes, and patterns of weather. Key concepts include:
a) temperature, wind, precipitation, drought, flood, and storms; and
b) the uses and importance of measuring and recording weather data.

So…I decided that a fun way for my 2nd graders to do this would be to have a rain gauge, measure and record daily rainfall, and produce a visualization that helps the students easily process this data.  I used Many Eyes to make the data visualization

Here’s an example of a bar graph with data I collected* from April 2009:

Here’s another example with a bubble chart with data I collected* from May 2009:

The bubble chart is a little confusing for rainfall because it leaves out the days (quite a few) when the rainfall was zero, but does show the great amounts well for comparison purposes.

*by collected I mean that I loosely based this on the Farmer’s Almanac for Richmond in April and May 2009. It is not the same data but it is similar to the actual rainfall data.
