lab 4 data

i am in tuesday morninng's lab from 10 to 12. And my group had the sample no. 37 for soil water percentage. i rocorded the air dried soil+ tin = 10.996 but when i look at the data for oven dried soil, # 37 is placed into wed. and the weight is 11.28 which is even bigger than the weight of air dried soil+ tin. i am so confused

i'm not sure if there's a different data sheet for all labs, but i'm in the wed lab and the readings i see for 37 are 10.99 total weight and 10.68 dry weight. it would be a pretty weird coincidence if another group 37 measured exactly the same. did you misread the 11.28?

JiahuiXiong For sample number 37 I see air dried soil+ tin = 10.99 and oven dry soil + tin = 10.68 (are you adding in the weight of the tin a second time? I am unclear how you get 11.28?)

JiahuiXiong and any others who have challenges with their oven dry weights or loss on ignition weights If your weights are "strange" (e.g. increase when they should decrease as noted above) please email Maja or Sandra directly maja.krzic@ubc.ca or sandra.brown@ubc.ca and we can provide you with a solution.
