Question?

• How will the weather affect the creek in a
  ten-month period?

California Standards Covered

• Investigation and Experimentation
• 7. Scientific progress is made by asking
  meaningful questions and conducting careful
  investigations. As a basis for understanding this
  concept and addressing the content in the other
  three strands, students should develop their own
  questions and perform investigations. Students
  will
• a. Develop a hypothesis.
• b. Select and use appropriate tools and
  technology (including calculators, computers,
  balances, spring scales, microscopes, and
  binoculars) to perform tests, collect data, and
  display data.
• c. Construct appropriate graphs from data and
  develop qualitative statements about the
  relationships between variables.
• d. Communicate the steps and results from an
  investigation in written reports and oral
  presentations.
• e. Recognize whether evidence is consistent with
  a proposed explanation.
• f. Read a topographic map and a geologic map for
  evidence provided on the maps and construct and
  interpret a simple scale map.
• g. Interpret events by sequence and time from
  natural phenomena (e.g., the relative ages of
  rocks and intrusions).
• h. Identify changes in natural phenomena over
  time without manipulating the phenomena (e.g., a
  tree limb, a grove of trees, a stream, a
  hillslope).

Materials/Methods

• GLOBE protocols-Atmosphere/Climate
• Rebar (6) placed in pairs at opposite shores, at
  three different locations
• Brick laying string (will be attached to rebar
  pairs
• Digital camera for documentation
• Metric rulers

Abstract

• Over a school-year period of time, students
  will investigate the level of this local creek.
  The beginning of this creek is located 3km away.
  Chollas Creek eventually feeds into the San Diego
  Bay. Most of it (75) travels through heavily
  populated areas. The area of the creek that my
  students would have access to and which would be
  safe for us to use, is 16 meters long. San
  Diego gets very little rain averaging less than
  25 cm per year.

Camera Usage

• Students will document water level, cloud cover,
  and vegetation growth at the creek.
• Students will also document their procedure to
  make into a power-point presentation for other
  students, parents, and community.

Data Transformation

• Monthly graphs will be made
• Data tables will be used
