WHAT ARE SOME METHODS
OUR EARLY ANCESTORS
USED TO COMMUNICATE
WITH EACH OTHER?
Cave Drawings and Early Language
Development
•
Primitive man in ancient cultures left behind cave
paintings and hieroglyphs. To save space and time,
pictures gradually became stylized and ultimately
evolved into characters.
Cave Drawings and Early Language
Development
•
As societies became more complex so did
languages; and as travel brought people of different
cultures together, written languages evolved further
to be more versatile. Hundreds of characters could
be narrowed down to a select set of "letters." An
entire language could then be represented using
various combinations of letters.
Perspective Drawings
•
•
•
Through observation, artists sought
methods to portray images of the
world around them.
During the time of the Renaissance,
perspective (space and depth
relationships) became a very
important part of the desire to
produce realistic images.
Vanishing Point
Maps
•
•
•
•
A physical map is a flat representation
of a 3D space.
The item can be as large as our solar system or
earth, or as small as chromosomal genes.
Maps show our world as a set of points, lines,
and areas, using many different features, such
as size, shape, value, texture, pattern, color,
and orientation.
The kind of map you use depends on the kind of
information you want to obtain or analyze.
CAN YOU NAME SOME
DIFFERENT TYPES OF
MAPS?
Different kinds of Maps
•
•
Road Maps – Show
roadways and physical
boundaries.
Topographic Maps –
Have contour lines that
show elevation.
Different kinds of Maps
•
•
Aeronautical Maps –
Have information about
flight paths.
Weather Maps – Show
locations of weather
patterns.
Different kinds of Maps
•
•
Concept Maps – There
are several kinds of
concept maps.
A spider map is
organized by placing the
central theme or unifying
factor in the center of the
map. Outwardly radiating
sub-themes surrounding
the center of the map.
Different kinds of Maps
•
•
The hierarchy concept map presents information in a
descending order of importance. The most important
information is placed on the top.
The flowchart concept map organizes information in a
linear format.
Different kinds of Maps
•
Gene Map –Shows locations of specific genes in DNA
•
Floor Plan – Shows rooms in a building.
WHAT ARE SOME TECHNOLOGICAL
DEVELOPMENTS THAT HAVE
ALLOWED US TO CAPTURE AND
DISPLAY VISUALIZATIONS?
Photography
•
•
The development of photography
depended on understanding the
physics of light to record images
and chemical processes to produce
permanent images.
The improvement of materials
(celluloid film) and processes
allowed everyone to enjoy the
photographic process. This process
allowed the pictures to be recorded
on an easy to use medium.
Television
•
With the invention of
television, images could
be brought into the
home.
•
Television combined
sound with motion and
eventually color was
added.
