Data Presentation and Analysis-

Graphs Graph – types X vs Y axis Scaling axis Plotting points Human Error Curve or best fit

line Labeling

Human Mistakes vs. Experimental Errors

Human Mistakes – carelessness Experimental Error –

instrument variation or technique

Random Error – chance variation

Systematic Error – system used for designing or conducting experiment

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.  

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.

Sample Station – Dichotomous Key

Have specimens of leaves Formulate a key or use a key to identify

specimens

Sample Station - Measurement

Identify range, capacity, incrementation Do measurement – estimate last digit

Sample Station – Experiment Analysis

Analyze the design of the experiment Identify variables Explain results – form conclusions

Sample Station – Microscopy

Determine the diameter of the field and the length of one cell in mm and convert to mcm.

Sample Station – Data Analysis

Making hypotheses

Food web analysis

Eating habit analysis

Predictions and conclusions

Inferences

Sample Station – pH

Determine the pH of various solutions using either pH probe or pH test papers.
