AIDE Earth Science Key
Points
Chapter 1 "Studying the Earth"
Lesson 1 "Earth Science"
Key Vocabulary Terms
- Earth science - Study of the
earths land, water, air, and outer space
- Geology - Study of the solid
parts of the earth.
- Oceanography - Study of the
earth's oceans.
- Meteorology - Study of the
earth's oceans.
- Astronomy - Study of outer
space and objects in it.
- Geologist- Scientist who studies
the solid pars of the earth and how they change.
- Metric System - System of
measurement used by scientists.
- Unit - Known amount used for
measuring.
- Meteorologist - Scientist
who studies the air and weather.
- Submersible -small underwater
research vessel.
- Oceanographer - Scientist
who studies the oceans.
- Astronomer - Scientist who
studies outer space and objects in it.
Key Concepts
- Earth science is the study
of the earth's land, air, water, and sometimes outer space.
- Geology, astronomy, oceanography,
and meteorology are the four main fields of earth science.
- Tools help scientists gather
and analyze information about the earth.
- Computers can make measurements,
store information, make calculations, and help scientists communicate with
one another.
- Earth Science is important
to your life because: Earth science can help inform individuals about weather,
earth science also helps communities to make wise decisions about the use
of land and its resources.
Did you learn these Objectives?
- Can you state what earth science
is?
- Can you list the main fields
of earth science?
- Can you name some tools used
by earth scientists.
- Are you able to give examples
of how earth science is important to you?
Lesson 2 "Understanding Maps"
Key Vocabulary Terms
- map- drawing that shows part
of the earth's surface as seen from above.
- legend - list of map symbols
and their meanings.
- compass rose - part of a map
that shows the major compass directions.
- scale - part of a map that
shows the relationship between map distance and actual distance.
Key Concepts
- A map is a drawing that shows
part of the earth's surface as seen from above.
- A map legend is a list of
map symbols and their meanings.
- The compass rose identifies
the major compass directions: north, east, south, and west.
- The most common map scales
are: bar scales, equivalence scales, and ratios.
- If a map scale reads "1
centimeter = 5 kilometers," 3 centimeters on a map acually is 15 kilometers
in real life.
Did you learn these Objectives?
- Are you able to explain what
a map is?
- Can you describe the parts
of a map?
- Can you use a legend and scale
to read a map?
Investigation
1-1 "Making a Map" (Optional, must complete 16 total investigations)
Key Concepts
- You will construct a map using
a map scale and legend of a familiar place.
Lesson
3 "Topographic Maps"
Key Vocabulary Terms
- Topographic map - Map that
shows the shape and elevation of the land surface.
- Contour line - line on a map
that connects points of equal elevation.
- Contour interval - vertical
distance between contour lines on a topographic map.
- Hachure - short line that
points toward the center of a depression on a topographic map.
Key Concepts
- A map that shows the shape
and eleevation of a land surface is a topographic map.
- A line on a map that connects
points of equal elevation is a contour interval.
- A steep elevation is shown
by close contour lines.
- Contour lines form a V when
they cross a valley.
- Bear Mountain is the highest
mountain on page 17.
Did you learn these Objectives?
- Are you able to explain how
contour lines show shape and elevation.
- Can you visualize the landscape
by looking at a topographic map.
Investigation
1-2 "Reading a Topographic Map" (Optional, must complete 16 total
investigations)
Key Concepts
- You will practice reading
a topographic map.

the map using 1 centimeter to represent 3 kilometers shows a larger part of
the earth because it represents and area that is30 kilometers by 30 kilometers.
the other map outlines and area that is 20 kilometers by 20 kilometers.
20.
Since a mountain is very tall, the contour interval should be large in order
to allow for a resonable space between contour lines. So 30 meters makes sense.
