22 Human Mistakes vs. Experimental Errors Human Mistakes – carelessnessExperimental Error – instrument variation or techniqueRandom Error – chance variationSystematic Error – system used for designing or conducting experiment
23 A Sample Dichotomous Key 1. wings covered by an exoskeleton go to step 2 1. wings not covered by an exoskeleton. . . . go to step 32 body has a round shape ladybug 2 body has an elongated shape grasshopper 3.wings point out from the side of the body . . dragonfly 3 wings point to the posterior of the body HouseflyNote: There should be one less step than the total number of organisms to be identified in your dichotomous key.
24 Sample Stations – Population Density Measure sample areaDetermine population density for symbolsAssign an organism to symbolsForm a food chainEvaluate sample – predict techniques, etc.
25 Sample Station – Dichotomous Key Have specimens of leavesFormulate a key or use a key to identify specimens
26 Sample Station - Measurement Identify range, capacity, incrementationDo measurement – estimate last digit
27 Sample Station – Experiment Analysis Analyze the design of the experimentIdentify variablesExplain results – form conclusions
28 Sample Station – Microscopy Determine the diameter of the field and the length of one cell in mm and convert to mcm.
29 Sample Station – Data Analysis Making hypothesesFood web analysisEating habit analysisPredictions and conclusionsInferences
30 Sample Station – pHDetermine the pH of various solutions using either pH probe or pH test papers.
