Bacterial Growth Simulation ?s

What type of growth pattern did your bacteria show during the first 4 rounds (before limiting factors)?

• Linear

• Exponential

• Random

• Constant

If you started with 10 bacteria and rolled a triple during the limiting factor rounds, what would your final population be?

• 20

• 25

• 30

• 40

Answer explanation

Work: 10 × 3 = 30 growth of +20 → half = 10 → total = 20

Which of the following are limiting factors that can slow bacterial growth? (Select all that apply)

• Lack of nutrients

• Unlimited food supply

• Waste build-up

• Limited space

• Perfect constant temperature

How does this model of bacterial growth connect to the way infections spread in real life?

Using your lab data:
Create a graph that shows how your bacterial population changed over the 10 rounds.

• X-axis: Rounds

• Y-axis: Number of bacteria
