Title: Earth Science


1
Earth Science
  • Unit 1 The Nature of Science

2
Earth Science
  • Compare the areas of study in Earth science
  • Identify Earth's Systems
  • Explain the relationships between Earth's systems
  • Explain why technology is important

3
The Scope of Earth Science
  • Astronomy-the study of
  • Meteorology--the study of
  • Geology--the study of
  • Oceanography--the study of
  • Environmental Science

4
Earth's Systems
  • Geosphere
  • Atmosphere
  • Hydrosphere
  • Biosphere
  • Technology
  • Homework Section 1.1 assessment 1-7
  • pp. 9
  • vocabulary pp.6 Due Thursday, 08-3-2012

5
Investigations
  • Visualizing Scientific Methodspp. 11
  • Students will explore scientific methods
  • Project
  • Clearly indicate the purpose, the hypothesis, the
    independent and dependent variables, and the
    expected results.
  • Use an Analogy Solve Crimes.

6
Homework
  • Section 1.2 assessments, 1--7, pp16.
  • Section 1.3--Vocabulary pp.17
  • Section 1.3 assessments 1--6, pp.19
  • Due on Friday, August 31, 2012.
  • Quiz on Chapter 1, Tuesday Sept. 4, 2012

7
Methods of Scientists
  • Section 1.2 Objectives
  • Compare/contrast independent and dependent
    variables
  • Explain the scientific notation

8
Scientific Method
  • Question
  • Research-Collect Information
  • Form a hypothesis
  • Design an experiment-test hypothesis
  • Conduct the experiment
  • Collect results--compare to expected results
  • Draw a conclusion
  • Report Results of experiment
  • Accept or Reject hypothesis

9
Variables
  • Independent Variable-manipulative
  • Dependent Variable-responding
  • Control--group that is compared to
  • Controlled Variables--things that are kept the
    same

10
SI units of Measurement
  • Length-- Meters
  • Mass--- Grams
  • Volume--- mL, cc,L
  • Temperature-Celsius
  • Time-seconds, minutes, hours,UTC
  • Atomic clock

11
Scientific Notation
  • Short-hand way to express numbers
  • If decimal point is shifted to the left--the
    exponent is positive.
  • ex 40000000000000000000004X10_
  • If the decimal point is shifted to the right the
    exponent is negative
  • ex 0.0000000001 1 X 10- m

12
Communication in Science
  • Explain why precise communication is crucial in
    science

13
Communicating Results
  • Lab Reports-experiments and investigations
  • Graphs--representation of data
  • Line Graphs
  • Bar Graphs
  • Models--Scientific models
  • Theories and Laws.
