Title: Earth Science


1
Earth Science
  • Unit 1 The Nature of Science
  • September 3,2013-Complete Scavenger Hunt, p. XXV

2
Earth Science Sept. 3,2013
  • Compare the areas of study in Earth science
  • Identify Earth's Systems
  • Explain the relationships between Earth's systems
  • Explain why technology is important
  • Review the safety worksheet
  • Analyze scientific inquiry and complete

3
The Scope of Earth Science September 4, 2013
  • Complete the Foldable on p. 5 Earth's Systems
    What is Science
  • Astronomy-the study of
  • Meteorology--the study of
  • Geology--the study of
  • Oceanography--the study of
  • Environmental Science
  • Read Termite Lab (Do Not Write On Lab)

4
Earth's Systems
  • Geosphere
  • Atmosphere
  • Hydrosphere
  • Biosphere
  • Technology
  • Homework Section 1.1 assessment 1-7,p 9
  • vocabulary pp.6 Due Thursday, 09-05-2013

5
Investigations Sept. 5, 2013
  • Visualizing Scientific Methodspp. 11
  • Students will explore scientific methods
  • Project Termite Lab
  • Clearly indicate the purpose, the hypothesis, the
    independent and dependent variables, and the
    expected results.

6
Homework
  • Section 1.2 assessments, 1--7, pp16.
  • Section 1.3--Vocabulary pp.17
  • Section 1.3 assessments 1--6, pp.19.
  • Chapter 1, Thursday, Sept.12 , 2013 (Test)

7
Scientific Method- Inquiry
  • 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

8
SI units of Measurement
  • Length-- Meters
  • Mass--- Grams
  • Volume--- mL, cc,L
  • Density --g/cm3,
  • DM/V
  • Temperature-Celsius
  • kelvin (K)
  • Time-seconds, minutes, hours, UTC
  • coordinated universal time based on
    cesium-133-element
  • Atomic clock

9
Variables
  • Independent Variable-manipulative-x axis
  • Dependent Variable-responding-y-axis
  • Control--group that is compared to the
    experimental group.
  • Controlled Variables--(constants) things that are
    kept the same for the control and experimental
    groups

10
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

11
Communication in Science-Sept. 9, 2013
  • Explain why precise communication is crucial in
    science- Launch Lab

12
Communicating Results
  • Lab Reports-experiments and investigations
  • Graphs--representation of data
  • Line Graphs
  • Bar Graphs
  • Models--Scientific models
  • Theories and Laws.
  • Quiz Friday,Sept 30, 2013--Diagnostic Test

13
Methods(Tools) of Scientists-Sept. 11, 2013
  • Section 1.2 Objectives
  • Compare/contrast independent and dependent
    variables
  • Explain the scientific notation

14
Questions
  • SI units-a standard system of units--called Le
    Systeme International d'Unites
  • Scientific Theory- is an explanation based on
    many observations during repeated investigations.
  • Scientific law-is a principle that describes the
    behavior of a natural phenomon.
