Lesson 6 H ome-Learning: How do bacteria grow in a simulated environment?
1. I magine you want to place the bacteria in a way that allows one variation to outcompete the others for space and a higher proportion in the population. In the space below, draw the necessary placement of the four variations of bacteria for this to happen. Identify which variation would have the highest proportion in the population.

NEXT STEPS:
3. How does what you figured out help us predict what might happen in our Petri dishes if they were left to keep growing?

4. N ow that we have figured out how bacteria are competing for space/food in our Petri dishes, what else needs to be added to this simulation to explore some of the questions we still have on our Driving Question Board?
