Your answers to the questions below will be used to measure your level of understanding of the concepts discussed and practiced during the last lab. Concepts tested represent just a sample of the many concepts studied. Please take your time and read each question carefully. Partial credit may be given where appropriate so show your work. Each question is worth the number of points noted in parentheses.

1. We used the scientific method to determine if there was a real difference in mass between popped and unpopped popcorn kernels. Describe what was found last lab for the kernels placed in the beakers with oil and popped on the hotplate; that is, report the general results (no numbers required) and give at least one possible expanation for the results found. (2)

2. We studied the Scientific Method. In your own words show your understanding of this method by explaining what it is. (2)

3. You look at an old aerial photograph and believe a property you are considering for purchase may once have been used to store gasoline in underground tanks. The possibility of past gas leakage into the ground has you concerned. A second property under consideration appears to be clean. You do a search of test procedures on the internet and find a way to determine the level of gas contamination in soil samples. Use your knowledge of the scientific method to, construct a NULL and an ALTERNATE hypothesis for further testing. ( 3)

4. The term "theory" is used quite differently by scientists and non-scientists, please explain the difference in meaning. (2)

Answer only one of the questions below:

5A. Error in measurement, and elsewhere, is a fact of life in the sciences. We must constantly be alerted to potential problems with our methods which introduce errors. Such error may interfere with our ability to clearly answer the question of interest. Explain or describe one possible source of error from ANY of the experiments completed last lab. (1)

5B. What is the difference between pseudoscience and non-science? (1)

3. You were asked to look at a slide with the paper letter "e" as the specimen of interest. If the letter e appeared on the slide as it reads in this question when looking directly at the slide without the microscope, sketch how the letter e would appear when viewed under 100x magnification. (1)

4. You observed Elodea cells in both water and sucrose solution and observed a striking difference in structure. On page 17 of the lab manual you were asked the question: Why did this phenomenon occur? Please answer the same question below.(1)

5. Explain how you determined the field of view with the 4X objective lens in place and the results obtained. (1)

6. A sketch of the compound microscope is shown below. Please name and give the function of the 4 lettered items (A-D). (2)

Name: ____________________________ Seat #: _______ Score _____

1. Define or explain the term "osmosis" as studied last lab. (2)

2. Normally one studies the diffusion of molecules but we studied diffusion of what measurable quantity last lab? (1)

3. You place a concentrated salt solution inside a membrane bag and place this bag into a beaker of pure water. Which solution is hypertonic and which is hypotonic? (1)

4. How did we determine the rates of diffusion last lab? (2)

5. Last lab each of you was asked to graph your results and come to some conclusions about what properties of diffusion the 3 model cells demonstrated. Use the graph paper below to completely and properly (including graph and axes titles) graph your general results, no specific numbers needed, and come to ONE significant conclusion which the data support. (Hint: I discussed at least 4 significant conclusions in the wrap-up at the end of class.)(4)

1. Why didn’t lugols solution react with the leaf of the Coleus plant which grew in the dark? (3)

2. We had the concept of both a positive and negative control introduced last lab, give an example of a positive control which you used. (3)

3. Last lab we used a pH indicator called phenol red. Describe how the test worked for that indicator solution. (3)

4. Photosynthesis and aerobic respiration are sometimes said to be reciprocal processes. Explain why this is so by writing the equation for one process and describing the connection with the second unnamed process. (3)

5. The test tube with Elodea in the light developed tiny bubbles as time went by. Why did bubbles form and what gas did the bubbles consist of? (3)

Please explain what the term "resolving power" means when used in reference to a compound light microscope? (2)

Explain how you determined the size of your cheek epithelial cell last lab. (2)

Name of microscope part is ___________________________ (1)

Function of that part is _________________________________ (1).

4. When does mitosis occur in the cycle of a cells life? ( 2)

5. You were asked to find and sketch cells of either the whitefish or onion root tip in each stage of mitosis last lab. Draw a sketch of a single cell in anaphase of mitosis, from the organism of your choice of the two named above. For full credit you must label all distinguishing parts of the cell you sketch in enough detail so that the stage sketched is identifiable as distinct from any other stage of mitosis. ? (3)
