Clarify Question
What is the key concept addressed by the question?
· This question is asking about the use of fungi in resolving an oil spill.
What type of thinking is required?
· Apply level:
o You are being asked to take what you already know and use, or apply, it to fungi as agents of remediation for an oil spill.
Gather Content
What do you already know about fungi? What other information is related to the question?
· Fungi absorb and then metabolize materials from their surrounding environment.
· Fungi are known for their ability to break down almost any organic compound, even jet fuel.
Choose Answer
Given what you now know, what information is most likely to produce the correct answer?
· Fungi are not photosynthetic, nor do they have central vacuoles, so those answers can be disregarded.
· Since fungi are well known for their ability to metabolize anything that is carbon-based, and oil is carbon based, it is reasonable to conclude that they may be used to break down oil.
Reflect on Process
Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
· Apply level:
o Answering this question correctly depended on your ability to use fungi in a new situation. If you got an incorrect answer, did you remember that fungi absorb and metabolize materials from their environment, or that fungi can break down a wide variety of organic compounds? Did you have trouble extending the abilities of fungi to determine the correct answer?
