(underline qualifiers) Large molecules do not cross semi permeablel membrane while small molecules can .; Molecule size matters when crossing a membrane What chain of reasoning (warrant) connectsthe evidence to the claim? In column 6, identify type of reasoning with the letter(s): for AUTHORITY (A), THEORY (T), or type of LOGIC: Analogy (AN), Correlation (C), Cause-Effect (CE), Generalization (G) What Evidence is presented? In column 3, identify the type of evidence with the letter: Data (D), Fact (F), Opinion (O), Theory (T). Evidence from lab goes here. The iodine crosses the “membrane” model while the starch does not D Generalization of the model Theory fluid mosaic Evaluate the quality of the evidence as poor, average or good. Explain your evaluation. Evaluate the quality of the chain of reasoning as poor, average or good. Explain your evaluation. Strength of Authority good data driven Application of Theory average not all of the theory tested Type of Logic generalization Reliability Validity Controlled Experiment Objectivity/bias What are your concerns about the believability of the claim? (your counterarguments, rebuttals or new questions)? How good is the model? Is dialysis tubing really the same as a cell membrane? What about experimental error? Accept, reject, or withhold judgment about the claim. Explain your judgment. ACCEPT the data shows that the large molecule starch does not pass through The membrane while the small molecule iodine does. C Bulgren revised 6/17./2008
