1. Aim: How do we measure the size of microscopic objects? OBJ: Given activity sheets SWBAT determine the field of view (FOV) and measure the size of microscopic objects with 70% accuracy. DN: Convert millimeters (mm) to micrometers (µm) and micrometers (µm) to millimeters (mm) ACT: Complete Measuring Size of Microscopic Objects and FOV Activity Sheets HW: Complete Microscope Quiz (MQ, Q:12-20, on scantron, due tomorrow). Work on Unit 1 Review Sheets, Lab Skills Exam, 9/24.

2. 1 millimeter (mm) = 1000 micrometers (µm).001 millimeter (mm) = 1 micrometer (µm)

3. Do Now a.2000 µm b. 4000 µm c. 1500 µm d. 800 µm e. 250 µm f. 2.0 mm g. 4.0 mm h. 1.5 mm i. 0.8 mm j. 0.25 mm
