Mammal Video Notes	Week 6 Recitation	Take detailed notes on mammalian video footage, including monotremes and marsupials.	While watching the clip from the "Life of Mammals" video (approximately 30 minutes), fill in notes on mammalian diversity on the next page.  Include this page in portfolio #3.  Also, be sure to get the stamp that you have completed the video notes in class.	This assignment is worth 3.0 points for completely filling in the video note sheet. The video notes need to be completed and stamped in your scheduled laboratory or during GTA office hours weeks 6 or 7 (no later) to receive credit for this assignment.
Before and After Project	Week 6 Laboratory	Connect science to another field by generating a visual work of art about changes in nature	Although creativity is a key component of scientific thinking and the research process, it is often stressed less than logical thinking and specific problem solving in science courses. In this portfolio assignment you have the opportunity to creatively link art with science. Explore the theme "Before and After in Nature" and develop a visual art piece that incorporates some aspect of change related to one of the themes we explore in the class this term (genetics, evolution, animal behavior). This change in nature can be something that occurs rapidly, or something that happens over a long period of time. The change can be shown as simply two views (before and after), or a sequential series showing changes occurring over time. The work can be a creative photo, a drawing, a construction, or other format, but it needs to fit (almost) flat into the portfolio. Along with your art piece, include your artist statement. The artist statement includes a thorough description of the concept you are trying to express with your art piece, the time period the change represents, and the materials used. Be creative and substantial in your exploration of the theme you select and your explanation of your piece. For safety, do not include any materials that are potentially hazardous, and collect responsibly. Direct your theme to something that could be displayed in a multi-generational public location. Some examples of Before and After in Nature" are on display in the hall cases outside of 133 Weniger.	This assignment is worth 5.0 points: 3.0 points for your art piece, and 2.0 points for your explanatory artist statement (1.0 point for description of concept, 0.5 point for time period of change, and 0.5 point for materials used). There are many ways to successfully complete this project, be thoughtful and produce substantial and meaningful work.
Predator Prey Data Analysis	Week 7 Recitation	Analyze and discuss predator-prey data.	Using the data in the chart provided on the next page, write a paragraph that describes the experiment conducted to determine how predator crab populations impact prey blue mussel populations.  Include the experimental design (the three different types of study sites and the mussel characteristics studied), a thorough description of the results, and what the data trends may indicate.	This assignment is worth 4.0 points (1.0 point for a description of the experimental design, 1.0 point for a description of the results, and 2.0 points for your analysis of what the results may indicate).
Cricket Observations	Week 7 Laboratory	Observe crickets and make detailed notes and drawings about physical structures and behaviors.	A cricket habitat will be set-up in the window of lab (129 Weniger) week 7. Observe the crickets' structures and behaviors. Make detailed drawings with labels and detailed writings. Include: a description of the tank habitat you are observing (location, time of day, lighting, etc.), physical characteristics of the crickets (shapes, sizes, colors, etc.), behaviors of the crickets (where they are in the tank, what they are doing, relationship between different crickets, etc.). Take some time to focus on sketching and describing different crickets, possibly of different ages or gender. Fine art skills are not a necessity; detailed labeling of sketches can be used if artwork does not adequately express the information you would like to convey. This is a five-point assignment, so sketches and descriptions should be thorough, as if you are describing the crickets in detail to someone who has never seen the species before.	This assignment is worth 5.0 points: 1.0 point for description of tank habitat (sketch and written notes), 2.0 points for physical characteristics of the crickets (sketch and written notes), and 2.0 points for behaviors of the crickets (sketch and written notes).
Human Pedigree	Week 8 Recitation	Construct a human pedigree based on family data.	Using the family history on p. 144, construct a human pedigree and determine whether the disorder is most likely dominant, recessive, or sex-linked. On the pedigree, indicate gender (circles or squares), relatedness (lines), names of the individuals, and indicate which individuals have the disorder. Include a sentence stating what you believe the genetic basis is of the disorder (dominant, recessive, or sex-linked) and a brief explanation of your rationale for this selection. For Tony and Donna (father and daughter) write their respective genotypes (AA, Aa, and/or aa) next to their names.	This assignment is worth 4.0 points (1.0 point for the pedigree, 1.0 point for the genetic basis, 1.0 point for correct explanation of the genetic basis selected, and 1.0 point for correct Tony and Donna genotypes).
Scientific Knowledge Reflection	Week 8 Laboratory	Reflect on how scientific ideas are subject to change and how scientific knowledge is durable.	This assignment is an opportunity to think about two aspects of scientific knowledge that were in the first week's assigned readings: scientific ideas are subject to change, and scientific knowledge is durable. Write two paragraphs explaining (teaching) these concepts to an adult. In the first paragraph, give an example of a scientific idea that has changed over time, and why it has changed. In the second paragraph, give an example of an aspect of scientific knowledge that has been durable, and explain why it may be durable. Several examples of these concepts are in the display case outside of 125A Weniger (next to Dr. Blair's office).	This assignment is worth 4.0 points: 2.0 points for the first paragraph (1.0 point for an example of a scientific idea that has changed over time, and 1.0 point for why it has changed) and 2.0 points for the second paragraph (1.0 point for an example of an aspect of scientific knowledge that has been durable and 1.0 point for explaining why it may be durable). This assignment receives a 1.0 point deduction if it is not in paragraph form.
