Experiment 1:
Question: How does the length of germination time effect the rate of CO2 production in alaska Alaska peas?
Independent Variable: Germination Time (Un-germinated, 24 Hours, 48 Hours)

Line of Best Fit and Calculating the Respiration Rates
In order to determine the respiration rate for each of the variables tested above, we must calculate the line of best fit for each dataset.
Recall, a linear equation has the form Y = mx + b b
Y= CO2 with units of ppm (parts per million)
m = Slope or Respiration Rate with units of ppm / second
x = time with units of seconds
b = Y-intercept (CO2) with units of ppm
Using Excel or Google Sheets, we can calculate our line of best fit and the respiration rate, m, with the data:
| Condition | Respiration Rate (CO2 ppm/second) |
| Un-germinated Alaska Peas | -0.008142835141 |
| 24 Hour Germinated Alaska Peas | 0.400294823 |
| 48 Hour Germinated Alaska Peas | 0.3947037469 |
| 24 Hour Germinated Mung Beans | 0.3296257508 |
| 24 Hour Germinated Soy Beans | 0.3539077248 |
| Crickets | 1.477949 |
We can then graph the data to visualize the rates of respiration for each sample:
