Unit 4 Earth and Space

TEKS COVERED DURING THIS UNIT ARE:

  • 8.7A: Model and illustrate how the tilted Earth rotates on its axis, causing day and night, and revolves around the Sun, causing changes in seasons.
  • 8.7B: Demonstrate and predict the sequence of events in the lunar cycle.
  • 8.7C: Relate the positions of the Moon and Sun to their effect on ocean tides.
  • 8.8A: Describe components of the universe, including stars, nebulae, and galaxies, and use models such as the Hertzsprung-Russell diagram for classification.
  • 8.8B: Recognize that the Sun is a medium-sized star located in a spiral arm of the Milky Way galaxy and that the Sun is many thousands of times closer to Earth than any other star.
  • 8.8C: Identify how different wavelengths of the electromagnetic spectrum such as visible light and radio waves are used to gain information about components in the universe.
  • 8.8D: Research how scientific data are used as evidence to develop scientific theories to describe the origin of the universe.
  • 8.9A: Describe the historical development of evidence that supports plate tectonic theory.
  • 8.9B: Relate plate tectonics to the formation of crustal features.
  • 8.9C: Interpret topographic maps and satellite views to identify land and erosional features and predict how these features may be reshaped by weathering.
  • 8.10A: Recognize that the Sun provides the energy that drives convection within the atmosphere and oceans, producing winds.
  • 8.10B: Identify how global patterns of atmospheric movement influence local weather using weather maps that show high and low pressures and fronts.
  • 8.10C: Identify the role of the oceans in the formation of weather systems such as hurricanes.
