Equipment: Equipment Celsius Thermometer- check weekly for accuracy by placing in an icewater bath (50% ice, 50% water). Leave it in long enough for the thermometer to stabilize. It should read within (+ or -) 1° Celsius. If it is not accurate, use another one. If the thermometer shows both Celsius and Fahrenheit scale, cover up the Fahrenheit numbers to avoid confusion. Note: some extension activities require more than one thermometer. Snow Depth Pole- a heavy meter stick works well. Meter sticks are easy to break as the snow crust hardens. To create a firm measuring tool, attach the meter stick to a 1"x 2" piece of lumber.If the meter stick shows US units, cover them up to avoid confusion. Snow Board- plywood board approximately 40 cm x 40 cm and at least 1 cm thick. Paint the snowboard white. Attach a thin flag to the board to make it easier to find after a snowfall.
