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 3 • 2 body has a round shape. . . . . . . . ladybug 2 body has an elongated shape. . . . . .grasshopper • 3.wings point out from the side of the body . . dragonfly3 wings point to the posterior of the body.. . . . Housefly • Note: 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 area • Determine population density for symbols • Assign an organism to symbols • Form a food chain • Evaluate sample – predict techniques, etc.

25. Sample Station – Dichotomous Key • Have specimens of leaves • Formulate a key or use a key to identify specimens

26. Sample Station - Measurement • Identify range, capacity, incrementation • Do measurement – estimate last digit

27. Sample Station – Experiment Analysis • Analyze the design of the experiment • Identify variables • Explain 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. Making hypotheses Food web analysis Eating habit analysis Predictions and conclusions Inferences Sample Station – Data Analysis

30. Sample Station – pH • Determine the pH of various solutions using either pH probe or pH test papers.
