for Rain Day
The students will measure different
amounts of water.
up 10 (or more, if desired) "stations" in
advance. Using the Normal
Monthly Precipitations link, pick a summer month
in which the precipitation amount will be rain and not
snow. Next pick the 10 cities which are going to
be represented. (Try and have a varied range of
measurements.) Then fill 10 containers with
water to the amount which equals each of the cities
you have picked (round to the nearest 1/2 inch.)
Set up the 10 stations by having a container of water,
a card with the name of the city, and a ruler at each
the students into pairs. Discuss with the
students what is represented at each station.
The amounts are averages which have been measured for
a 30 year period. (Some years there may be more
rain, some years less, but on the average this is the
amount that falls for the given month.) Give
instructions on how to measure the water.
out the Measuring
Rainfall Worksheet and have the students travel
through the stations, measuring the amounts of water
and recording it on their papers.

arrange the average rainfalls from least to greatest.

cups. Have the students create puddles of
different sizes using the measuring cups. How
big is a 2 cup puddle? (Measure its
diameter.) How big is a 5 cup puddle?
story problems which involve rainfall. For
example, it rained 2 inches on Thursday and 1 inch on
Friday. How many inches did it rain altogether?
