Engage: Take notes about the following questions as you watch the film clip.
How does tuberculosis spread?
What does it mean for tuberculosis bacteria to be resistant to drugs (antibiotics)?
What do you think resistance to antibiotics has to do with evolution?
Explore: Study the diagram and key below with your partner. Use the following vocabulary to explain how this population of bacteria can evolve through natural selection to be more antibiotic resistant: variation, survive and reproduce, over time, resistant, antibiotics.
Initial Bacteria Population Immediately After Antibiotics Final Population
Bacteria Treatment Bacteria can be treated with ___________________. People should only use antibiotics when _________________ because their overuse can result in
antibiotic _________________ - to avoid or withstand the effects Antibiotic resistance example: Let’s say an antibiotic kills 95% of bacteria. The 5% of bacteria that
were not killed were _________________ to the antibiotic and they may survive, reproduce and pass on that gene for resistance. Over time, there will be a large colony of this resistant bacteria and the first antibiotic will not be able to stop them!
Using the petri dish on the right, which antibiotic is the most effective? _______In your own words, what is the antibiotic doing to the bacteria? ______________________________Petri dish - a shallow, circular, transparent dish with a flat lid, used for the culture of ________________________.Culture - the process by which cells are ______________ under __________________ conditions, generally outside their natural environment.
Explore: On your own, study the two graphs and answer the questions below.Measles are a VIRUS!
Write down one conclusion you can make based on the graph.
Write down one observation you have about the graph.
3. A student comes down with an illness and goes to the doctor hoping to get antibiotics to get better quickly. Her doctor tells her that she has a cold, which is caused by the rhinovirus. Should she take antibiotics to get better? Give evidence and reasoning to support your claim.
