6th Grade Earth Science
What are we currently working on in class?
Temperature Changes in the Layers
The Layers-Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
The Composition-78% Nitrogen, 21% Oxygen, 1% other gases
Radiation, Convection, and Conduction
Earth's Systems-all of the matter, energy, and processes within Earth's boundary
Geosphere-the solid, rocky part of Earth.
Atmosphere-the layer of gases surrounding Earth
Hydrosphere-the part of Earth that is liquid water
Cryosphere-all of the frozen water on Earth (glaciers, ice bergs, etc.)
Biosphere-all living things and the areas of Earth where they are found
Weathering, Erosion, and Deposition
How do rocks change over time?
The Rock Cycle
Three Main Types of Rocks and Minerals
Divergent Plate Boundaries
Convergent Plate Boundaries
Transform Plate Boundaries
How does plate tectonics work?
What are the plates?
What are the types of plate movements?
What do plate movements create?
How the Theory Developed
Evidence for the Theory
Theory of Continental Drift
Earth's Interior Layers
Five Physical Layers-Lithosphere,Asthenoshere, Mesosphere,Outer Core, Inner Core
Compositional Layers-Crust, Mantle, Core
Radiation, Conduction, and Radiation
Energy/ Heat Transfer
Earth's Layers and Interior
Measurement- SI International System of Units
Metric Measuring of Lines, Mass, and Volume
Error in Measurment-Why is it a big deal?
Mean (Average), Mode, and Median
Scientific Theories-Big Bang Theory , The Theory of Plate Tectonics, The Thoey of Continental Drift
Scientific Laws-The Law of Gravity, The Laws of Motion, The Law of Conservation of Enerergy and Matter
Steps of the Scientific Method: Ask a Question or State a Problem; Hypothesize and Predict, Test Your Hypothesis, Analyze Results, Draw Conclusions, Communicate Results
What is science? 3 main branches of science Descriptions,Explanations-- Inferences, Observations; Types of Data-Qualitative and Quantitative
Types of Experiments or Investigations--Observational vs. Experimental
