Why Is Evolution Important Now? Antibiotic Resistance

Students participated in an adapted activity found at:
http://www.newtonsapple.tv/TeacherGuide.php?id=1279
then did the following assignment:

If a bacterium can divide and produce 2 bacteria every 20 minutes, how soon will the two initially surviving resistant germs reach a total of one million organisms? 10 million? 100 million? One billion bacteria? Populations of this size, if pathogenic, are more than adequate to cause great harm.

Students then completed a note-taking study guide that is a companion to the following web site: http://www.microbeworld.org/microbes/bacteria/
The study guide can be found at: http://www.middletownhs.org/apps/pages/index.jsp?uREC_ID=41979&type=u&rn=2686883

Students watched Debi's Story about antibiotic resistant tuberculosis, as part of a lesson about why understanding evolution is important now. They also watched a video about diseases.

Students watched a video titled: Why Is Evolution Important Now? This video is available to watch online at: http://www.pbs.org/wgbh/evolution/educators/teachstuds/svideos.html
