Day Four - 6/18

Events presided over by Dr. S. Stonedahl
What we did
    Caleb cleaned counters
    Attached final bottom corner guard

The hopefully finished Ant-farm Apparatus  

    Took two settled K-value measurments of 2nd sand (mason sand) {K = 0.000585m/s,0.000583}
    Filtered 3rd sand (traction sand: Mastercraft)
    Changed sands in permeameter from 2nd sand to filtered 3rd sand
    Exterminated air bubbles  D:
    Cleaned lab area

Water seems to get everywhere

    Ran a K-value tests of filtered3rd sand (traction sand, filtered) {K = 0.000705 m/s}
    Emptied permeameter
    More Air bubbles were Exterminated D:
    Ran a K value Test with no sand {"K" = 0.002214}
    First SRI lunch.
    Changed sands in permeameter from filtered 3rd sand to unfiltered 3rd sand
    Had to exterminated even more air bubbles  ! D:
    Ran a K-value tests of unfiltered 3rd sand (traction sand, filtered) {K = 0.000943 m/s}
    Devised way to test if 1st sand (play sand) was still usable

The bucket apparatus, a way to test if our filters are causing the play
 sand to act strange and  maybe eventual wash our sand

    Began test on 1st sand (play sand)
    MATLAB code can produce res. time distributions now

Another NetLogo simulation

What we will do
   Implement tested K-values in computer code.
   Take settled K-value measurement of 3rd sand (Traction sand, unfiltered)
   Take more K-value readings for 1st sand (play sand)
   Go shopping for other sands

SELFIE TIME!!!! !!! !  !!
