3. Metric Conversions Kilo Hecto Deca UNIT Deci Centi Mili 103 102 101
10-1
10-2
10-3
Start with the unit that you have and count left or right the number of spaces to move the decimal.
For example….
If you have one meter as your “unit” and you want to know how many millimeters…. Count 3 spaces to the left
1.0 Meters = 1, millimeters

G: Mass L: Volume M: Length C: Temperature
Do the following conversions…
1000 mL = ? L
kg = ? G
m = ? Dm
0.05 ml = ? L

Copy Table 1 from lab into notebook

6. Microscope Compound light microscope Electron Microscopes
Light passes through the specimen and uses 2 lens to form an image, magnifies up to about 1000 times.
-Magnification: How much larger an image is
-Resolving power: ability to distinguish two objects that are close together from one another
Electron Microscopes
use beams of electrons to produce the image
