1. TOPIC: Microscope AIM: How is a specimen measured with a microscope?
Hypothesize…… How tall is Ms. Phillip?

2. Micrometers/ Microns µm 1mm = 1000µm 1m = 1,000,000µm What unit
is used to
measure
cells?
Micrometers/ Microns µm
1mm = 1000µm
1m = 1,000,000µm

3. Paper thickness =
about 150 µm

4. Human hair diameter = µm

5. SHRIMP EGGS

6. Move decimal three places to the right
mm  µm

7. Example:
3.2 mm = ?
3. 2 µm

8. 0.7634mm = ? µm 
763.4 µm

9. Move the decimal three places to the left
µm mm
Move the decimal three places to the left

10. Example:
789 µm = ? mm 
.789 mm

11. 53.6 µm = ? mm 
.0536 mm

12. Smaller  Larger =
move decimal to left
um  mm

13. move decimal to the right mm um
Larger to smaller =
move decimal to the right
mm um

14. SLL LSR
Silly Little Leprechauns Like Spring Rain

HINT:
1000um
2mm =
2000 um
