Dom and Ms. Risch traveled to the main campus of Western Connecticut State University to work with Dr. Molinelli on testing our sunscreen samples. We were limited on time and equipment so we decided to test Sample B and D, as they were the samples with the best consistency. Dr. Molinelli worked to find a solvent in which our samples were soluble. That turned out to be THF (tetrahydrofuran). We ran a blank standard- just THF on its own, and then our samples. It was found that both samples seemed to absorb UVC, but not UVA or UVB. This seemed a bit strange, but we were encouraged by some level of absorbance for our sample. Dr. Molinelli also gave us a tour of the chemistry labs, including the Chemistry Club room which had a periodic table blanket and lots of Chemistry board games!

In class today getting close to the June 1st date and we got a lot done. One thing that was a challenge was the project reel. With the project reel after having it finally completed the edit software ran into a few technical difficulties we had to work around but we finally exported and uploaded it to the launch pad. We also made huge movements toward experiments getting over 15 trials done and organized the data. We have also made four solutions for Sunbrew sunscreen using the data and information we collected based off the other solutions. While we still have a lot of work to do we have made great steps towards the ultimate goal.
In class today, our team continued to work in different groups: Ingredient Experimentation, Product Experimentation, and Website/Booth Design. In the Ingredient Experimentation group, we continued to test different amounts of each ingredient mixed together to observe the consistency of our mixture, and prepared this new mixture to give to the Product Experimentation group, which started to experiment with our first mixture. They spread this on a plastic bag with UV detecting beads inside to see how much the beads would change color when comparing them to UV detecting beads without any mixture spreaded on it. Our beads tested with our sunscreen stayed a light blue, and some even stayed white. The beads without our sunscreen became a darker shade of blue, meaning that they absorbed more UV rays. This meant that our product was successful, which is why the Ingredient Experimentation group continued to refine the amounts of each ingredient so it would better protect against UV rays at a more consistent level. The Website/Booth Design group worked on finishing up our team’s Website by updating it with all of our current information such as blog posts and experimentation results. They also worked on the finishing details of our booth, such as the design/theme that it would be, and what we would have to show people visiting. This included the Project Reel, showing our team and our product, so we could put it in LaunchPad and possibly include it to show at our booth. Another thing that our team accomplished was to confirm one of our member’s appointments with a Westcon expert, where we could get information about how we can improve our product, and test it out to see if it is truly effective at being a sunscreen.
Today was a very productive today in the lab! We solidified our constant for our qualitative data with the UV reactive beads by putting 20 beads in a ziploc bag for 3 minutes under a UV light. From here our plan is to test all of our ingredients individually and record the data, then test the final combination. Our ingredient list is finally solid, which is going to allow us to finally make solid tests on our ingredients. The spectrophotometer forced group was working on learning how to operate the equipment and designing an experiment to be able to get quantitative data. Tomorrow our group is going to focus on setting up marketing strategies, booth design and starting the presentation planning. Everything is moving well!
