This week you will study building stones around campus and have the opportunity for some extra credit too.
Find the rocks shown in the images below and answer the questions below. Their location is marked by the white arrow.

| I Math and Science Center entry way | J rock slab in front of life sciences building |
The questions for each site are the same, please answer them briefly: (Note - all work must be done independently. If you had in a classmate's answers it will be considered academic dishonesty.)
a) Name the rock type (igneous, sedimentary, metamorphic) and give a brief explanation of your answer
b) What are the minerals present in the rock. Note: Not every black mineral is mica! there are amphiboles and pyroxenes as well, and you guys know how to distinguish them (cleavage angle)
c) How was this rock formed?
d) Any other observations.
Extra Credit:
What is a "Transit of Venus" and why did the German Kaiser consider it important enough to send a bunch of scientists to Trinity to observe it. Couldn't they have done it back home in Berlin? (4 points)
Who the heck was T.C. Brownell ? (1 points - yes, life is unfair, science answers count more)
