Systematic 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 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 . . dragonfly 3 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. Sample Station – Data Analysis
