When I was at UC Berkeley I had the opportunity to teach on many occasions, mostly
for the introductory classes. During this period developed a large number of worksheets
and other documents that have remained in extensive use by other TA's even up to the
present time. I post these materials here for the benefit of other researching developing
classroom activities for their astronomy sections.
