On Monday, we went to lecture and learned about aerosols, then we did an experiment to see how the gasses expand and form clouds. In the experiment, we used a plastic bottle and put ozone gas as well as a match into it to act as aerosols. We then pumped air into it, and then quickly took out the suction in order to rapidly lower the pressure, which caused the gasses to expand. After the morning lecture, we went to lunch at the Canyon Vista Marketplace. Then, in the afternoon, we did a titration for potassium iodate. 

In the morning on Tuesday, we had a lecture by Henrik I. Christensen for Science Communications on robotics. In the zoom lecture, we learned more about self-driving vehicles, and the ethics behind them. After lunch, we went back to the lab and worked on our projects. Some of us went to labs in York Hall while others stayed in the lab to work on their presentations. 

On Wednesday, we learned how all organic compounds in the atmosphere eventually turn into oxygen. In addition, the surplus of aerosols makes it harder to rain because it increases the ratio of water particles to the aerosols, which means that the water droplets won't be heavy enough to form rain clouds. In the afternoon, we made a circuit board for a current of electricity so that when we added it into a sodium chloride mixture diluted with de-ionized water that also had hydrochloric acid, it would turn the solution neutral and not acidic. 

Thursday's Zoom meeting was about Women in Stem. They discussed the struggles of being in a heavily man-dominated field and how it impacted them.  As well as how they navigated their path and how people who might be in their position should deal with their situation. Then in the afternoon, groups were finishing collecting data and started presentations. 

On Friday, we had two guest speakers, who discussed their field and how they are standing in front of us talking about themselves. Our first guest speaker was Ryan Simkovsky, who is the Vice President of Scientific Affairs at Algenesis. Algenesis is a common that creates footwear and surfboards that decompose into the earth. He explained his passion of science and how he is helping the world, and how we can do the same.  Our second guest speaker was Bryce Borders, an alumni of Cosmos from 2016 and is a responsible Engineer on Dragon Structures on Dragon Structure TPS at SpaceX.  He gave us lessons he learned from COSMOS and UCSD. Since he is near our age, he explained what it is like to work in STEM.  Both guest speakers gave us a lot of insight and we are grateful for their time and dedication. In the afternoon we determined the alkalinity of seawater using a different technique, which was using a Gran Plot. We did titrations to see how the pH changed.
