Evaluating Toxicity

Now that you have finished counting the seeds for each of the petri dishes assigned to you, determine the percentage of seeds that germinated for each petri dish. After calculating those values, follow the instructions in your lab manual to complete this portion of the experiment. The steps are summarized below.

• Plot germination % vs concentration (% w/v)

• Convert concentrations from % w/v to M (molarity = mol/L)

• Plot germination % vs concentration (M)

• Plot germination % vs concentration (% w/v) for class data

• Plot germination % vs concentration (M) for class data

• Answer wrap up questions
