It's tough for you my audience to realize the amount of science that is done in an entire day. All of this is done while setting up camp and tearing it down daily to keep moving. Sleds are undone and redone with equipment, tents, materials, sleeping bags, and food. Science, life is happening, days are busy…
I have not forgotten your SWEeeeeee problems!!! So from yesterday's problems, you should have calculated the volume of the snow from the snow depths.
Remember, we also take the mass of the snow samples by using a balance. So let's calculate the density!!!
Density = mass /volume
So, All you have to do is divide. The volume you calculated is in cm^3 or ml. Here are your masses. Remember I dealt with Ziploc bags out in the cold to find the mass, the least you can do is divide on the calculator in your warm classroom.
Got it, GREAT!!! Now tomorrow, we calculate SWE's – snow water equivalence.
SO WHERE IS MRS. CHEUVRONT???? LET'S PLOT!!!
Longitude 65.32788 North
Latitude 162.00528 West
Camp Haven proved to be a cozy, nice sleeping spot. The wind blew hard at times during the night, seeping through the cracks of the cabin. We performed our measurements amongst the woods of Camp Haven in the morning and then departed onward to new territory. Matthew stops frequently and checks GPS coordinates along with maps. Eric scans ahead for the trail and the best route. More measurements were taken at a windy tundra site. We entered the Koyuk River territory where the snow is dotted with forests of spruce trees. We are predicting that we will arrive at Buckland on Easter Sunday. The Arctic moon is full tonight, shining as a bright beam against the cold sky…….
TIME TO START GRAPHING THE HIGH AND LOW TEMPERATURE!!
Let's make a line graph showing the temperature extremes throughout the trip. Science uses degrees Celsius to measure temperature so that we will be the unit I will report in. Special Thanks to Glen for setting up the thermometer and taking the readings!!!!
High –13 Celsius
Low –22 Celsius
Conversion formula: To convert from Celsius to Fahrenheit:
Degrees Celsius X (9/5) + 32 = Degrees Fahrenheit
