Part 2- The Microscope
•Invented in the 1500s
•Robert Hooke was the first to see cells
•Anton van Leeuwenhock was the first to see living things
![Page 5: Rules for using the microscope. Carry with two hands Always start with low power](https://reader035.vdocuments.net/reader035/viewer/2022062803/568147a3550346895db4dbfe/html5/thumbnails/5.jpg)
Total Magnification Power
•The power of the eyepiece lens X the power of the objective lens being used.
•10x X 40x = 400x

International System (SI)
of Measurement
![Page 7: Rules for using the microscope. Carry with two hands Always start with low power](https://reader035.vdocuments.net/reader035/viewer/2022062803/568147a3550346895db4dbfe/html5/thumbnails/7.jpg)
Advantages of the Metric System
• Creates an international system of measurement that uses the same standards world wide
• Ease of recording and calculating– All units are based on units of 10– Very precise measurements can be recorded
with decimals NOT fractions.
![Page 8: Rules for using the microscope. Carry with two hands Always start with low power](https://reader035.vdocuments.net/reader035/viewer/2022062803/568147a3550346895db4dbfe/html5/thumbnails/8.jpg)
Subdivisions can be divided again and again for more
precision….1 unit
.01 unit
.001 unit
(Again by tenths)
![Page 9: Rules for using the microscope. Carry with two hands Always start with low power](https://reader035.vdocuments.net/reader035/viewer/2022062803/568147a3550346895db4dbfe/html5/thumbnails/9.jpg)
“Base” Units• Unit of Length- Meter
– Based on the distance from the N. Pole to the equator
• Unit of Volume- Liter– The space an object takes up (solid, liquid or
gas)
• Unit of Mass- Gram– The amount of matter in an object
![Page 10: Rules for using the microscope. Carry with two hands Always start with low power](https://reader035.vdocuments.net/reader035/viewer/2022062803/568147a3550346895db4dbfe/html5/thumbnails/10.jpg)
•A. FROM KILO TO MILLI
Important prefixes to know:
BASE UNIT
DECA 10x HECTA 100x
KILO 1000x
DECI .1
CENTI .01MILLI .001
The base of any unit determined by what you are
measuring
A prefix that makes a unit 10x
larger than the base
This prefix changes the
base into a unit 100x larger
This prefix changes the
base into a unit 1000x larger
This prefix changes the
base into a unit 1/10 as large as
the base
This prefix changes the
base into a unit 1/100 as large
as the base
This prefix changes the
base into a unit 1/1000 as large
as the base
Metric prefixes can be placed in front of all
metric units!

Metric ToolsBalance – used to
measure mass (grams)
Graduated cylinders and
beakers – used to measure
volume(liters)Meter stick –
used to measure length
(meters)

Microscope• Used to magnify objects and make small
details more apparent.
• Compound microscopes have two lenses that magnify the object. The eye piece and the objective lens.
• Total magnification = eye piece X obj. lens
• 3 objective lenses: 4x, 10x, 40x
