Tonight's homework is to complete Assignment 34B. Remember, it is being collected tomorrow (Friday for 11BD). Students in 11BD can also find the homework for Monday below.

Assignment 34B - Capturing School of the Future Analysis and Reflection

Answer all of the following questions to the best of your ability. Use details, vocabulary, and examples whenever possible.

1. List potential sources of error that could have affected your estimation of the population.

2. What difficulties did you encounter with this experiment? What additional difficulties might be present in a field study?

3. Was your estimate close to the actual population size? If no, how could the accuracy of the activity be increased?

4. Why would a scientist want to be able to estimate population size of different organisms?

5. TO BE COLLECTED AND SCORED…Discuss or two of the most meaningful errors and the specific impacts it/they may have had on the data and/or how you interpreted it. What changes did/would you make and why? Discuss each change made or potential change and predict how it would specifically change the data.

Reflection Checklist (4 Skill Points)                                              SCORE: _____

Criteria	4 (Mastery)	3 (Proficient)	2 (Approaching)	1 (Needs Revision)
Identifies relevant sources of error.	Clearly identifies and describes at least one relevant source of error that is NOT simply human error during the experiment.	Identifies and describes one relevant source of error that is NOT simply human error OR clearly describes a source of error that is simply human error during the experiment.	Identifies but does not clearly describe the source of error in the experiment.	Identifies but does not attempt to describe the source of error.
Describes how the data is changed by the error.	Specifically and clearly describes how the data collected was altered by the error.	Clearly describes which data was altered by the error but does not clearly describe how it was altered.	Addresses that the source of error changed the data but does not explain its effect clearly.	Does not address how the source of error changed the data.
Proposes changes to procedure to eliminate/minimize sources of error	Clearly defines a logical change to the procedure that should be made AND clearly explains why it should be made.	Clearly defines a logical change to the procedure that should be made and only acknowledges why it should be done.	Defines a change to the procedure but does not explain the reasoning behind it OR proposes an illogical change but explains its rationale.	Does not propose a logical change to the procedure.

11BD Homework for Monday

Read and take notes on "Population: 7 Billion" from the January 2011 issue of National Geographic. Be sure to check out some of the links to pictures as well. If the above link doesn't work then try this or this.

Think about:
- What concerns are associated with humankind's rapid population growth?
- Is our growth occurring equally everywhere on Earth?
- What, if anything, is being done to deal with population growth?
