4.17 Carbon Cycle Lab & Quiz
In order to answer each quiz question correctly, you will need to...
1.) Complete a virtual lab simulation for "The Carbon Cycle" found on the following website: http://sepuplhs.org/high/sgi/teachers/carbon_sim.html |
* Open a separate browser window (or tab) so you can complete the quiz while you work through the lab exercise. |
After submitting your completed quiz, be sure to review the graded version for autograding accuracy. Please know that I am more than willing to reevaluate the autograding of a question (or questions); however, you will need to let me know when human intervention is desired. If you discover a response has been marked as incorrect by the autograding feature and you feel it is an acceptable answer based on my grading guidelines, send me a k-mail message with the affected question number or numbers.
Thank You!
