What we did
Took settled K-value measurements for 3rd sand (traction sand,Unfiltered)
{K =0.000683,0.000606}
Filled Apparatus with 1 inch of water to check for leaks.
Found leak near bottom back right corner
Cried.
Removed silicone on the corner, so that the leak could be fixed following aquarium fixing instructions.
Set up Permeameter to test how much a small sand will flow into the larger one
 |
| Testing if the different sands will flow into each other |
 |
| This test has more similar K-values between the teal and black, resulting in a different flow pattern |
Ran NetLogo program with K-values that have been measured from sands.
Purchased new Silica Sand at K & K hardware.
Lunch break at Subway.

| Food |
Measured porosity of Mason Sand.
Took first measurement of Silica Sand K-Value
{K = 0.000479}
Put more silicone on the Apparatus to fix leak.
Some of us played Volleyball (click on pictures and look at Caleb G. in both).
Pick two sands that have the most varying K-values.
STOP THE LEAK (if it still exists)
Get more porosity measurements
Set up apparatus
Add res times to main code
Streamline code if possible (make two programs into one)
more research into sands

| Internet research doesn't make very interesting pictures |
I got the Lowes pea gravel, ordered an external harddrive and two more pumps from amazon, and bought a white huge "hardboard" thing that barely fits in the car even after cutting it in two pieces, which we can use as a backdrop for pictures (Caleb G.'s suggestion). We should try out the timelapse camera sometime, so it's not a hold-up later.
