Topic: The Sun, Transits and Eclipses

Grade Level: 9-12

Body: Sun, Venus

Mission: Heliophysics Missions (Sun), Venus Express (Venus)

Science Education Standards:


By the end of the 12th grade, students should know that:

  • Because the Earth turns daily on an axis that is tilted relative to the plane of the Earth's yearly orbit around the sun, sunlight falls more intensely on different parts of the Earth during the year. The difference in intensity of sunlight and the resulting warming of the Earth's surface produces the seasonal variations in temperature. 4B/H3** (BSL)

National Science Education Standards

Science and Technology -- Content Standard D

Grades 9-12

  • Heating of Earth's surface and atmosphere by the sun drives convection within the atmosphere and oceans, producing winds and ocean currents.
