How to set up your weather station
A Weather Kit provides a measurement tool for wind, rain, and temperature
and may also have a chart for cloud typing. It can be mounted permanently
in the schoolyard on a post, or, teachers have mounted it to a moveable
rod (round ½"-1" dowel, or square 1"x1" stick) set into a coffee can filled
with gravel or sand. The moveable unit is the most adaptable and will
potentially have the longest life.
In addition, we have seen a teacher decorate the rod with Native American
- themed ribbons and designs so it becomes a traditional-style Weather
Stick.
Set out the weather station in a location that is far from buildings
or other wind obstructions. It has screws to mount it, and it is important
to also mount it as level to the ground as possible (if in a can of gravel
or sand, this adjustment will always need to be reset ). Mount the metal
swivel with the two screws first. Then on the main body add the rain gauge,
thermometer, wind velocity indicator, and total rain indicator. Then place
the flat compass rose base on the metal swivel, followed by the main body,
and then topped by the swivel cap to hold it all in place.
Using a compass, position the compass rose on the north-south line. The
compass rose should remain stationary while the body with its gauges will
swivel around following the wind. Wind speed is determined by the wind
velocity 'arm' on the station.
How to Use the Weather System
Once a day, an appointed student or team of students, should take a reading
out in the schoolyard. Ideally, there will be a set time for the reading
- first thing in the morning, noon hour, etc. Record precipitation (any
water in the clear vile), sky conditions - sunny, cloudy, overcast?; temperature,
wind velocity and direction. Also record cloud type and direction they
are moving at that time of day. If you have access to a barometer, then
that measurement can also be included.
Upon returning to the classroom, have an appointed student enter the data
gathered onto the Camp Weather Report form. It is also advisable to keep
a written Weather Log in the classroom for referral when not online.
Weather Forecasting
Advanced classrooms can also experiment with weather forecasting. Using
the cloud chart to understand what different cloud formations are indicative
of, combine a cloud reading with wind direction and velocity, and any
current precipitation. It will be possible for students to make a prediction
of the next day's weather. If you also have a barometer in the class,
your predictions will increase in accuracy. It is suggested that each
prediction made be first written into a classroom Weather Log, and then
be written up and posted on a bulletin board in the classroom. And then
the next day, a comparison can be made to determine the accuracy of the
previous day's predication. One additional layer to this process that
can be beneficial is to assign specific students to watch their local
television weather report one night a week, Mondays - Thursdays, and then
bring a synopsis of that local prediction into the class and record it
in the Weather Log. Students will see how many days their predictions
were right, how many days the weatherperson was right, and sometimes,
what days the students were right and the weatherperson was not !
