  9. Laboratory Skills Assessment How many millimeters wide is the field of view shown? 12.0 mm

  10. Laboratory Skills Assessment How many millimeters wide is the field of view shown? 12.0 mm

  11. High Power Objective lens = 40X Low Power Objective Lens = 10X High Power Field of view = Diameter of the Low Power field of view ÷ (HP ÷ LP) (HP) ÷ (LP) ------ 40X ÷ 10X = 4 2000µ ÷ 4 = 500µ

  12. Field of View: Approx. 3.3 cm 500μ*1.3cm 3.3 cm Organism 1: Approx. 1.3 cm

  13. 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 Average Width 1.3 cm

  14. #4 500µ * 1.3 cm / 3.3 cm = 197µ 500μ * 0.56 cm / 3.3 cm = 84.8μ 500µ * 0.75 cm / 3.3 cm = 113.6μ

  15. The mass indicated on the scale is: 47.52 g

  16. The mass indicated on the scale is: 129.07 g
