Biology in the News 
The biology concepts presented in this course encourage you to make the connection between textbook biology and biology that appears in daily newspapers and weekly periodicals. This assignment will encourage you to make the connection between the textbook and the world you live in and to recognize how science and technology influence and contribute to modern culture.
This assignment is worth 20 points.  Late work will count half credit.
Select an article from a current newspaper, periodical, or the Internet which correlates with the content of one or more units of instruction covered in the course. Appropriate sources are any major newspaper, news website, scientific magazines, or any other major news source for the public.
Tips on choosing an article
– Article MUST relate to content presented in class
– Article is an appropriate length for the assignment (not a tiny blurb, not 10 pages long)
– Article MUST BE less than 3 months old
– Article is news, not reference material, and from a reputable source
– Article MUST be readable by the general public, not scholarly.
Your essay should consist of the following three items:
1) A cover page, including your name, course and section number, date and instructor name
in the upper right corner, the title of the article centered on the page, and works cited or bibliography at the bottom of the cover page.
2) The body of your essay, which should consist of three carefully prepared paragraphs, each a
minimum of 4 sentences, double spaced.
Paragraph one: Summarize the article with the who?, what?, when?, where?, why?, and how? of the main ideas in the article.
Paragraph two: Correlate the article with a unit of instruction covered in class. Give specific information you learned in class, citing the text and or lab manual sources, and explain how it helps you understand the article, or contradicts the article.
Paragraph three: Give your personal reaction and explain why the content of this article is important to you, your friends, or family. This involves relating the topic of the article to real life, by answering two or more of the following questions.
1. Did the article make you aware of things you had not thought of before?
2. Did the article change your mind or feelings about the topic?
3. Was the article about something you have experienced personally?
4. Did the article address any ethical, value, or public policy issues?
5. Do you agree or disagree with arguments presented in your article? Explain. 6. If you were “in charge”, how would you proceed with the information in the article?
3) A copy of the article must be attached, either copy and paste at the end of the article, or attach as a separate article. 
This assignment must be your own work. No plagiarism will be tolerated. Papers that the instructor determines contain plagiarism in any part will be given a zero for the entire paper. See http://www.plagiarism.org/ for more information on what is plagiarism. Do NOT cut and paste information from any source into your paper. Use your own words to relay information from the article, text or any other source. Then cite the source of that information using a standard citation format.

final applied lab project biology

Final Applied Lab Project

Addresses course outcomes 1-4:

  • recognize and explain how the scientific method is used to solve problems
  • make observations and discriminate between scientific and pseudoscientific explanations
  • weigh evidence and make decisions based on strengths and limitations of scientific knowledge and the scientific method
  • use knowledge of biological principles and the scientific method to ask relevant questions, develop hypotheses, design and conduct experiments, interpret results, and draw conclusions

This is the culminating assessment in BIOL 103. It is designed to assess your ability to apply the principles of the scientific method. For this project, you will complete the activity below. Make sure to address all points (questions) associated with the activity.
 
Final Applied Lab Project
Design an experiment in which you will test the effect of an acidic fluid on enzymatic activity. (Recall: enzymes are proteins.) To complete this project, it may be useful for you to review the Scientific Method Tutorial (found the Course Content section of the classroom under the ScienceLearningCenter link) and the Scientific Method lab (Lab 1), so that you can better understand how to design an experiment.  It may also be helpful for you to review your textbook and Lab 4 (Enzymes).  As you review Lab 4, you will be reminded that there are several factors that impact enzymatic activity: pH, temperature, and amount of reagent.  Feel free to refer to observations and information from Lab 4 as you complete the questions required in the Final Applied Project (see the questions below).
As you design your experiment for this project, please remember that you are trying to examine how an acidic fluid will modify the outcome of an enzymatic reaction.  To successfully complete this project, you will need to identify the question(s) being asked in your experiment and the hypothesis that you are testing.  In your experimental design, you must clearly explain what you are doing. That means that you will need to identify the enzyme and the acid, as well as explain your experimental protocol (this information will help you to answer question 2).  You must also thoroughly explain how the addition of the acidic fluid impacted the overall reaction process (this information will help you to answer question 4).
Hint: Keep in mind that the acid will change the environmental conditions of the experiment (for example, a low pH value could change the shape of the active site on the enzyme protein), without directly participating in the reaction.
 
Lab Materials
You may need the following, depending on your experimental design:
Materials in your lab kit:

  •  none

Additional materials you may need:

  • plastic beakers or cups
  • hydrogen peroxide solution (from Lab 4)
  • yeast (from Lab 4)
  • sample of fresh meat, about 1 cm cubed in size (unprocessed and uncooked, e.g., liver, steak, fish, or poultry—particularly organs)
  • sample of fresh vegetable, about 1 cm cubed in size (e.g., potatoes or other root vegetables)
  • a pen for labeling the beakers or cups
  • a ruler with centimeter markings

Remember, the goal of this project is for you to evaluate the effect of an acid on enzymatic activity.  As part of this assignment, you must identify your source of enzyme and the acid used.  As you work though this project, you must also make sure that the following questions/points are addressed:
1. What question are you asking? Clearly state your hypothesis.
2. Design an experiment. Provide a detailed account of the materials and methods used to conduct the experiment. Also include the methods for data collection and analysis.
3. Conduct the experiment and record your results below. What did you observe? Which samples showed bubbling?
4. Use your knowledge about enzymes to interpret your results. It may be necessary for you to refer to your textbook. What effect does the acid have on the enzyme?
5. Was your hypothesis supported? What is your conclusion?
6. Cite all references used to complete your Final Applied Project.

On what basis is electrophoresis able to separate molecules?

Virtual Lab 4:           Genetics II

A. Learn how electrophoresis works and answer these questions:
•    On what basis is electrophoresis able to separate molecules? What are the lengths of the three DNA bands that you produce in this lab?
B.  Electrophoresis. Select the pBR322 plasmid (a circular piece of DNA used as a cloning vector) to analyze (menu in upper left hand corner of the simulator). You will then see a diagram of the circular plasmid DNA along with the points along the length of the plasmid where the various restriction enzymes (EcoR I, Ple I, Hinc II, and Bgl I) will cut the DNA. For instance notice that the enzyme EcoR 1 only cuts the plasmid at one location at the top of the diagram, whereas the other enzymes cut the plasmid at other places. To analyzes the DNA we cut it up with different enzymes and slowly piece together an understanding of the entire sequence.
•    Load each lane as follows: lane 1 with Bgl 1; lane 2 with EcoR 1; lane 3 with Hinc II; lane 4 with Ple I; lane 5 with predetermined molecular weight markers.
•    Run the gel and describe and explain the number of bands in lanes 2 and 4.
C. Human blood types and the immune system: Emergency Transfusion!
You can skip the video introduction, but will probably want to read the guide before you attempt the emergency simulation. Repeat the simulation until you can get hired on by the virtual hospital staff. Use your mouse to: 1. Take a blood sample from the patient. 2. Place the blood sample in the antibody solutions. 3. Hang the correct blood transfusion bags, so as to start a blood transfusion.
•   Identify the different blood types, the antibodies associated with each, and the types of blood that each type can receive and donate too.

Virtual Lab 3:           Genetics I

 A. Phenotype and genotype of Dragons For fun, you can use this web lab to answer these questions: What genotype(s) result in wings? What genotype(s) result about a brown skinned Dragon? If necessary use your own research to answer the following questions.
•  Define genotype and phenotype.
•  What is an allele?
B. Drosophila Lab Enter the lab as a guest. You need to purchase a breeding pair of  flies. Purchase a female mutant that has a small (vestigial) wing size and a male wild type fly. Breed them and notice the resulting distribution of phenotypes.
•   Describe and explain the characteristic of the first generation (F1) of flies. Is the vestigial wing characteristic dominant or recessive?
•   What percentage of the F1 generation would show the recessive characteristic phenotypically according to your table?  Are your experimental breeding results consistent with what you expect from this assumption and the logic of the Punnet square?
•   Breed two of these F1 flies. To do this select a male and a female from the results of your first cross and put them in the breeding jar. Describe and explain the characteristics of the second generation (F2) flies.
C. Genetic Disorders Library Describe the three main classes of genetic disorders and give an example of each.
