Why Is Evolution Important Now? Disease Prevention

On February 27, students read an article, MRSA and The Science Classroom, and answered the questions that go with the article.  The article can be accessed online at:

Students also started a hands-on genetics activity where they are creating a karyotype of male and female chromosomes.
