This week we washed and sanitized our plastic pieces, making sure that they were free of debris or any growth. This was interesting as we were trying to find ways to get the "gunk" off of them. Needless to say, it got kind of messy. We really had to make sure the bacterial growth was off entirely and since they're small plastic pieces, my clumsy self lost one for a moment. Thankfully Luisa was able to spot it!
Random note: They're numbered 1 through 6, in which each plastic is a different type. So plastic #1 is PET or Polyethylene Terephthalate, plastic #2 is HDPE or High-Density Polyethylene, plastic #3 is PVC or Polyvinyl Chloride, plastic #4 is LDPE or Low-Density Polyethylene, plastic #5 is PP or Polypropylene and lastly, plastic #6 is PS or Polystyrene.
After sanitizing them, they were each weighed individually. Below is the data that was collected from the plastic pieces that were retrieved in January. And they were the same ones that we took from the canal water to perform gram staining test.

To Melissa,Washing plastic and sanitizing them as well is such a hard task. I am happy you manage to find the missing parts of your project. That is true teamwork there! The weight of each type of plastic seems very consistant and that will allow more precision in your project. Good luck on your project!

ReplyDeleteThis is such a great start! I love how organized you and your team are! Being organized is key to good research and it will really help and pay off in the end. So I see your group is working with all main 6 plastics! That is fantastic! I know my team was working with Polystyrene too but we decided to not really focus too much on it because it was so static!
