Exercise 1 Questions
1. What patterns do you observe based on the information in Table 4?
The closer the pH is too neutral (7pH) the higher the number of colonies
that are present.
2. Develop a hypothesis relating to the pH level of the culture media and the
number of microbial colonies observed in each culture.
The number of colonies increase when pH scale is closer to neutral.
3. What would your experimental approach be to test this hypothesis?
Analyse the number of colonies in different pH levels.
4. What would be the independent and dependent variables?
IV: pH of the solution DV: Number of colonies
5. What would be your control?
, H2O will be the control group
6. What type of graph would be appropriate for this data set? Why?
A bell curve to show the distribution of colonies based on the ph.
7. Graph the data from Table 4.
The number of colonies

8. Interpret the data from the graph you made in Question 7.
The farther from neutral (7 pH) the less colonies that will appear.
