4／20 Soil Sand Rocks

So today Marianne gave me more soil experiments! except this time it was with all these different samples. there were sand, rocks, and dirt.
Using tubes and ID water, I was able to test the PH of different samples of soil and compare them to see what kind of soil has the highest PH.
Using the big thingy from last post's picture. I was able to separate again the different sizes of the particles inside the soil and calculate each size's distribution.
Sand, of course, has the smallest since each particle size was tiny.
I continued to put samples of them into the oven in order to calculate different organic compound's size. However, they have to stay in the oven over night. Thus, I wasn't able to finish.
Thus, I ended up helping cleaning up the lab because there was going to be a check through on the lab after my internship. I realized that everything in the lab needs to be very carefully cleaned. All the beakers, pipets, and other stuff all need to be washed many times with water, soap, ID water and dried in order to pass the standard.
