curiosity, honesty, openness, and
skepticism in science and will exhibit these traits to
understand HOW the world works.

Have you heard these
words before? Where?
They will help you with
your science words!
4
Simple Microscope
Similar to a magnifying glass and
has only one lens.
Simple
sentence:
One subject
and one verb.
5
Compound MicroscopeLets light pass through an object and
then through two or more lenses.
Compound sentence:
2 or more subjects and
verbs in one
sentence.
6
Stereoscopic Microscope
Gives a three dimensional view
of a LIVING object.
(Examples: insects and leaves)
Stereo: multi-directional
7
Electron MicroscopeUses a magnetic field to bend beams of electrons;
instead of using lenses to bend beams of light.
Magnets
attract
remember?
8
LensEnlarges an image and bends the
light toward your eye.
9
Eyepiece Lens
Usually has a power of 10x (doesn’t change)
10
Objective Lenses in Smitha’s microscope
Low Power = 4x
Medium Power = 10x
High Power = 40x
11
Microscope MATH
Eyepiece Lens X Objective Lens = Magnification
10x (eye piece) & 5x (lens) = _______
10x (eye piece) & 10x (lens) = ______
10x (eye piece) & 40x (lens) = _______
Why didn’t the eye piece number change?
Science Math TimeAre you ready to…MULTIPLE?
Eye Piece Lens Total Magnification
10x 5x
10x 50x
10x 75x
10x 100x
10x 150x
12
Throw your hands in the air,
add the zero like you just don’t
care…
now you can multiple by ten!
Microscopes in Action
Have you noticed that in restaurants, there are signs encouraging employees to wash their
hands.
WHY?
If you had a microscope with you…what could you see?
Would you still eat there? Write a paragraph explaining your answer.
