Why Is Evolution Important Now? Antibiotic Resistance

Students participated in an adapted activity found at:
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:
The study guide can be found at:
