The students will be assessed on their group work, if they were respectful and stayed on task.  They will be assessed informally by their responses to discussion questions and formally assessed on their posters, fullfilling 4 of the 5 criteria:

  1. Is the poster legibly constructed?

  2. Can you clearly follow the paths the chemicals take?

  3. Do they include all pertinant intersections and relavent information?

  4. Are the intersections and information correct?

  5. Can this information be conveyed easily to others and used as an instruction tool?Students will be provided with these requirements and a short rubric containing all the elements their posters are required to have.

Although it does not count for a grade, students will also be required to fill out a 1-minute “ticket out the door”, in which they include any quesitons or concerns they had for the days lesson.  They will also be evaluated on the completion of their homework assignment.  They will be required to read and answer questions about a research paper.  The quesitons are as follows: What is their hypothesis? What are the main conclusions? and How did they arrive at those conclusions?  The students will also be required to write down 2 or 3 questions of their own about the paper, to be answered and disscussed in class the next day.

Pre-assessment Instruction Questions

  1. What do you think is the difference between all of these? (Refering to the bins of soil, mulch, compost and water)

  2. Would anything change if you added producers? Consumers? Why?

  3. What are somethings you know about the way nutrients flow in nature?

During Instruction Questions

  1. How might the addition of fertilizer affect the cycles?

  2. What about the addition of mulch/compost? Will that affect the carbon cycle? If so, how?

  3. How does acid rain fit into these cycles? If it is incoporatated into the water cycle, what affect will you see, if any, in the nitrogen, carbon and phosphate cycles?

Post Instruction Questions

  1. Are these cycles interrelated? If so, how?

  2. Think of these cycles in terms of your biomes (made last week), how do these reflect the cycles found in nature?  How are they different, besides size?

  3. How do you or your family impact the biogeochemical cycles around/near your house? Explain your reasoning.
