In all of the labs there has been scientific ideas and theories that explained why the procedures we used to analyze the evidence worked. However for most of the scientific ideas I had no idea why it worked. For example In the "Ink is still wet" lab the alcohol made the ink grow and separate yet I had no idea why the alcohol caused separation. In the "Killer Coffee" lab as well as the "Ink is still wet" lab we used a colorimeter to determine the absorption. The colorimeter was another procedure we did that I wasn't sure how it calculated the absorption.
2. How has your approach to lab procedures changed from the first round of labs? Are you more/less confident in your results?
I realized during these labs how vital reading the directions closely is. For this round of labs I went to the labs more clear and confident on what I was doing. Since I was more comfortable in the steps I took during the lab I was more confident in my results. I was also more comfortable with the procedures or tools I used during the second round labs. Since this was my second round of labs I had less questions about the tools used and more experience using them.
