TRANSCRIPT

• Lab & Safety Skills Manual

• Making Tables

• Making Graphs

• Making Histogram Graphs in Microsoft Excel

• Making Graphs

• Making Graphs

• Making Circular Graphs in Microsoft Excel

• Laboratory Skills AssessmentHow many millimeters wide is the field of view shown? 12.0 mm

• Laboratory Skills AssessmentHow many millimeters wide is the field of view shown? 12.0 mm

• High Power Objective lens = 40XLow Power Objective Lens = 10X

High Power Field of view = Diameter of the Low Power field of view (HP LP)

(HP) (LP) ------ 40X 10X = 4

2000 4 = 500

• Organism 1: Approx. 1.3 cm

Field of View: Approx. 3.3 cm

500*1.3cm 3.3 cm

• Find the width of the organisms by measuring across the organism at several places. Find the central tendency or average width. 1.5 cm 1.4 cm 1.2 cm 1.3 cm 1.1 cm 1.3 cmAverage Width

• #4500 * 1.3 cm / 3.3 cm = 197

500 * 0.56 cm / 3.3 cm = 84.8

500 * 0.75 cm / 3.3 cm = 113.6

• The mass indicated on the scale is: 47.52 g

• The mass indicated on the scale is:129.07 g
