Station 3
Controlling Bacteria with Antibiotics:Some types of bacteria cause disease and can be controlled by anitbiotics(anti means life, biotic means living). Antibiotics are drugs that kill or slow down the growth of bacteria. Some antibiotics are very specific in the types of bacteria they control however. Some bacteria are also very resistant to antibiotics. Scientists can grow bacteria in a petri dish to determine the type of antibiotic that will be most effective in controlling the growth of bacteria.

Procedure:
- Observe the two petri dishes above.
- In your journal, write a paragraph that describes the experimental design and compare the effectivness of the different antibiotics on controlling this strain of bacteria. Use evidence to support your answer.
