What does it mean?

Mrs. Andrews — Wed, 15 Feb 2012 01:14:43 +0000

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).

Please share your thinking with us! Put your first name & initial at the top of your comment!

How the Investigation Was Conducted

Mrs. Andrews — Tue, 24 Jan 2012 22:43:37 +0000

Fourteen gray oyster mushroom cultures were used in this study, which examined their ability to metabolize motor oil. Eight cultures were injected with various volumes of pure 30-weight motor oil. One control culture in each test group was not injected with oil. All cultures were watered with well water or filtered water with chlorine removed . Using a 10 cc syringe, test cultures were injected with either 10 ml., 20 ml., 30 ml. or 100 ml. of motor oil. Data showing each fruiting body (mushroom) count and their respective masses in grams, are shown in Data Collection #1 and Avon Data.
