Day 14

Today for our morning meeting we went to the drone lab to see what types of things they do an after that we were taken up on the roof of the building that we do all of our work in to see the view. After the meeting me and my lab partner starting working in our lab. We started the first trial with the gravel but soon realized that for the gravel we needed to change the sieve sizes we use for the gravel. We need a wider distribution of the larger sieves rather than the smaller ones. This is because most of our sample stayed in the top sieve of the stack of them. As shown in the chart below:

We weren't gonna change the sieves for all 3 samples but in this case we don't have a way around this and if we want a better distribution we have to change the sizes for the gravel sample. After we finished this trial and calculated the percentages we came back down to our lab and started to figure out what sieve sizes we should use. We decided that we were gonna do the other 2 trials tomorrow and instead continue working on the manual image analysis we had to get down for both the sand and also the clay & silt combination. For most of the rest of the day we worked on taking the images from the camera and the microscope and did the manual image analysis on the ones we could as of now. We decided to do this most of the day because it takes a long time to to this analysis.
