These are the total masses of oyster mushrooms that were harvested from all three 6th and 7th grade classrooms:
Control 10 ml. oil 20 ml. oil 30 ml. oil
19.6 grams 69.0 grams 54.8 grams 42.9 grams
1. Describe the difference between the mass of control mushrooms and those that were treated with motor oil.
2. Do you think the data shows random variation or do you think the motor oil promoted mushroom growth? What makes you think this?
3. Describe another experiment that could be done with oyster mushrooms or another bioremediator to test their pollution cleaning ability in an environment of your choosing (soil, a saltmarsh, river or marine environment).
