We did not do to any wet lab research today, but we evaluated the results from yesterdays lab work. To review, we mixed up acid solutions, at different molarities, and subjected webbing to each of 15 simples of acids. We evaluated the simples of acid and webbing immediately and 24 hours time intervals. Our evaluation was strictly on a qualitative level with three categories: color, clarity, and viscosity. We approached Tom with the problem of quantitative analysis of the tested simples. He needed time to thank of possible solutions to the problem and will give us an answer tomorrow. Dr. Yarger is interested in our results. Scott took some great video of the spiders silking which we will post on the Wiki in the next day or two.
In the afternoon we discussed modeling and many different ideas and concepts involved. It is good for teachers to discuss, brainstorm, and even to argue. It would be helpful to model the models!
