Astronomy

• In astronomy we will study such topics as the sun
  and other stars, planets and other objects in our
  solar system, lunar phases, tides, and eclipses.

4
Meteorology

• Here we will take a look at cloud and
  precipitation types, storms such as hurricanes
  and tornadoes, and fronts, pressure systems, and
  weather maps.

5
Oceanography

• We will explore our four major oceans, the
  properties of seawater, ocean floor and coastline
  features, ocean sediments, and major ocean
  currents.

6
Geology

• Here we tackle a variety of topics including
  minerals and rocks, volcanoes, earthquakes,
  faults and folds, soils, erosion, mountains,
  plate tectonics, and geologic history.

Earth Systems

• Although we study four branches of earth science,
  there are many interactions between earths
  systems. You are standing on the ______sphere.
  You are breathing in part of the ______sphere.
  If you went to the beach or canoed down the James
  you where visiting the ______sphere. And you and
  all the other living things on earth make up the
  _____sphere.

Scientific Method

• When solving problems scientifically we follow a
  series of steps to avoid wasting time, effort,
  and resources. These steps include
• 1. Defining the ________ (may include research or
  observation)
• 2. Stating a ____________ (explanation of
  observation must be able to be tested)
• 3. _________ the hypothesis (involves measurement
  of one variable at a time)
• 4. Analyzing the _________ (data organized in
  graphs, tables, and charts)
• 5. Drawing _____________ (returning to step 2 as
  needed)
• This is not a rigid, step-by-step outline.
