Quiz/ Problem Set #1 WGECTW MOD 1 Rubric Code: AXCC442 Ready to use Private Rubric Subject: Biology Type: Quiz Grade Levels: Undergraduate

Quiz/ PS #1 Descriptions In the absence of phages, what does the growth of bacteria look like under conditions of low, medium or high resource availability (0.5pt)?
	Present 0.5 pts	Absent 0 pts	Not in use (N/A)	Not in use (N/A)
Q1 0.5 pts The ideal answer has the three datasets generated by the model. The screenshots should be included as per the instructions Enter description	Present All three screen shots present	Absent No screen shots present. Add this note: As per the directions, screen shots are required for this assignment. Rather than penalize you throughout, I will take off the credit for this question	Not in use	Not in use
Quiz/ PS #1 Based on these findings, what can you conclude regarding the relationship between nutrient availability and bacterial growth? (1.5 pts)
	Excellent 1.5 pts	Good 1 pts	Fair 0.5 pts	Poor 0 pts
Q2 1.5 pts The levels of nutrients directly correlates with bacterial growth	Excellent	Good	Fair	Poor
Quiz/ PS #1 Under high resource availability, what does bacterial growth look like with a burst size of 2, 52 and 100? (0.5 pts)
	Excellent 0.5 pts	Good 0.25 pts	Poor 0 pts	Not in use (N/A)
Q3 0.5 pts Ideal: three screenshots, one for each condition. Also accepted, a clear description of the three conditions	Excellent All three screen shots present or all three conditions described	Good Some combination present but less than 3 (2 or 1 described)	Poor None	Not in use
Quiz/ PS #1 How does the impact of phage on bacterial growth change under less than ideal nutrient levels? (1.5 pts)
	Excellent 1.5 pts	Good 1 pts	Fair 0.75 pts	Poor 0.5 pts
Q4 1.5 pts Ideal: repeat the previous question by showing the same three phage bursts but at lower nutirents. (screen shots of words) The best answers have a comparison to the high nutrient case	Excellent Data and comparison	Good Data, with no comparison, OR Comparing only one burst size between high and low nutrient conditions	Fair Just a sentence that sort of gets at the comparison, but doesn’t have any data to back it up	Poor No comparison made, but tried
Quiz/ PS #1 Based on these findings, what can you conclude regarding the relationship between nutrient availability the impact of phages on bacterial growth? (2 pts)
	Excellent 2 pts	Good 1.5 pts	Fair 1 pts	Poor 0 pts
Q5 2 pts Ideal answer actually draws a relationship between nutrients and phages and how they impact bacterial growth	Excellent A new conclusion is drawn based on the modeling, that includes both variables;	Good There are two conclusions, and they are not really connected - but they match the modeling	Fair The conclusions did not require the model to be drawn	Poor No conclusions
Quiz/ PS #1 Based on these analyses, generate a hypothesis (proposed explanation made on the basis of limited evidence as a starting point for further investigation), and then explain the conditions you would use to test your hypothesis in the lab based on this modeling exercise (2 pts).
	Excellent 1 pts	Good 0.75 pts	Fair 0.5 pts	Poor 0 pts
Hypothesis 1 pts The ideal answer is a specific hypothesis that is based on the data generated from the model	Excellent A hypothesis is clearly stated. The hypothesis is specific, and could only have been generated from the data in the models.	Good A hypothesis was generated, but it is really general, making it hard to test. A hypothesis was generated, but it doesn’t really take into account both variables, or it does so seperately	Fair A hypothesis was generated that does not match the modeling data	Poor No hypothesis is given
Quiz/ PS #1 Based on these analyses, generate a hypothesis (proposed explanation made on the basis of limited evidence as a starting point for further investigation), and then explain the conditions you would use to test your hypothesis in the lab based on this modeling exercise (2 pts).
	Excellent 1 pts	Good 0.75 pts	Fair 0.5 pts	Poor 0 pts
Experiment 1 pts The idea experiment tests the hypothesis is a lab based experiment that tests a specific hypothesis, including both variables.	Excellent Both variables considered. Well controlled, lab based experiment. Directly tests the hypothesis. Discusses how you would measure the outcome	Good Designed an experiment, with both variables. The description is a little vague. These answers may suffer from a hypothesis that is too broad	Fair Designed an experiment that only considers one variable, and does not consider them together. Designed the model, but in the lab. These experiments could work for any hypothesis and were not specific	Poor Proposed more modeling and not a lab experiment
