• MCHS freshmen biology students were fortunate to receive a California Condor biotechnology kit from the San Diego Zoo Institute of Conservation Research. They had an opportunity to study about the endangered condor population, recovery, genetics and conducted a gel electrophoresis lab to determine the sex of the condor DNA. Our Wonderful Wizards did a terrific job!

  • Paleontology: Dig Field School I had the opportunity to participate in the DIG Field School through the University of Washington & Burke Museum. Dr. Greg Wilson, postdocs & students provided an engaging experience for teachers. This short video shows the process and topography of Hell Creek, Montana. We found numerous microfossils and macrofossils. It was a fascinating experience!

    Thank you to San Diego Zoo Institute for Conservation Education for providing the California Condor biotechnology kit. Students have learned about the restoration of the condor population, genetics and utilizition of gel electrophoresis to idenitfy the sex of this incredible bird. It has a wing span of 9.5 feet!

    During the 2012 summer I was fortunate to  participate in the Teacher Workshop in Conservation Biology.  The program was fabulous providing extraordinary training and cutting edge research in conservation of animals and plants. We will be performing unique laboratories throughout the year to support our biology curriculum. The staff and workshop at Safari Park provided a terrific experience!  The Conservation Education Program at the Safari Park sponsored a field trip for all MCHS biology students last year and once again this year. It was a fantastic experience, where students performed a biotechnology lab on the estrous cycle of elephants and toured the Safari Park.
