PAN Day 3 Soldering queen

Soldering isn't as bad as it sounds...Aim, melt, move and do another.

We began the day with the cosmic connection. Peggy mentioned trying to figure out a lab where one would find what galaxy a star came from. I still have not found the answer to how one can tell how old a star is. I really thought the answer was by temperature but upon talking with Peggy discovered age is a relative term meaning when the star was born rather than old age. Her answer was the composition of the star depending on the amount of iron it has in it. The star is more heavier, more iron as it ages.

Origins of element, search for dark matter at DUSEL, and meteorites were other topics discussed.
Upon a discussion with Dr. E. I understand more about nuetrinos, myons and tau.

Dr. Robert McTaggert from SDSU joined us and described topics and experiments to be completed at DUSEL. This presentation was interesting and I am sure most of us look forward to the possibilities of studying in the laboratory in the near future.

Our afternoon was spent completing a lab about barium detection. Instrument expertise is still not my stong points but I am becoming a bit more comfortable poking around.

My group is working on the circuit board. Finding where the circuits belong is harder than soldering.
I also presented my teaching presentation on determining which direction cosmic rays are coming from. I am glad I live in town so that I had the materials needed for the experiment. Because of where I teach, I try to simplify experiments and approach things from other angles. This thinking comes naturally for me and is probably why I have an MA in spceial ed.

Looking forward to day4,
Angie
