All experimental data can be found on the Hinton Google Drive here

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)

...

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:
