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 = 1,000.00 millimeters
METRIC CONVERSIONS Kilo Hecto Deca UNIT Deci Centi Mili 103 102 101 10-1 10-2 10-3 G: Mass L: Volume M: Length C: Temperature Do the following conversions… 1000 mL = ? L 0.00056 kg = ? G 25.567 m = ? Dm 0.05 ml = ? L
Microscope Compound vs Electron Microscope Magnification calculations What’s the main difference Resolving power Magnification calculations Multiply Eyepiece X objective) Function of the various parts… Copy Table 1 from lab into notebook
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
