Square bullet Activities

  • Setup:

    find a location of relatively uniform snow cover, which will receive a uniform amount of sunlight each day

    using willow wands or other small-diameter posts, mark out one-meter squares in the plot (leave walk spaces in between)

    leave one plot without any cover

    on several other plots put different amounts of some available dark materials such as dirt, ashes, or coal dust; barely dust one plot; put different amounts, evenly spread, on the others; weigh the material or measure its volume so that later you know how much you put on each plot

    you might choose to use several materials, some darker than others; don't make it too complicated.

  • Measurements:

    each day at the same time (within an hour), measure the snow depth in each plot with a marked wand probed down to the ground; record the measurements m centimeters; you might want to average several probes in each plot (this requires a little math-adding and dividing)

    record the temperature

    record the sky condition (sunny or cloudy)

    report any snow or rainfall that may occur (available from Federal Aviation Administration or the Weather Bureau)

    record average wind, either crudely, or get average daily wind reports from the airport

    continue these measurements until all the snow is gone from all plots

    record any unexpected events you think might affect the results, such as dogs or moose walking through the plots

    it is a good idea to graph the various results as you go along each day, to keep interest up.

  • Write up a report:

    analyze the effect of wind, temperature, cloud cover, etc., on the rate of melting

    include class or individual opinions on the report

    send a copy of the whole report to the Geophysical Institute.
