### More great cold and snowy activities:

Wind chill - Students use the National Weather System chart to gauge wind chill, examine the patterns that correlate increasing wind and/or decreasing temperatures, use wind chill numbers to estimate possible wind and temperature factors, and generally become familiar with this sort of interpolation and calculation. 5.OA.3, 6.EE.1, 6.EE.2, 7.EE.3, 7.EE.4, 8.EE.7, HSA.REI.B.3, HSF.LE.A.1, HSF.LE.A.4, MP4

It sure is cold out ... or is it? - Students ponder the relationship between place latitudes and average January temperatures while they try to discover a correlation. Is this a linear or near linear relationship? … averaging, missing data for averaging, line of best fit, Google Earth, world locations, linear review, extrapolation … This lesson is chocked full of interesting mathematics and world awareness. 6.SP.5, 8.SP.1, 8.SP.2, 8.SP.3, HSS.ID.B.6, HSS.ID.C.7, HSA.CED.A.2,  HSF.LE.A.1

How much snow is that? - How many inches of snow produced that pile?  How much snow in volume is on top of the car?  How much could that snow weigh?

Students try to approximate the weight of the snow by using our snow water equivalent percents (SWE) and their own thoughts about how dense this snow might be. 5.MD.C, 6.RP.A, 7.RP.A, 7.EE.B, 7.G, 7.EE.A
