Short Description: Students observe images of the sun and match the magnetic images to the corresponding ultraviolet images.
The Sun, Transits and Eclipses
Grade Level: 5-8
Heliophysics Missions (Sun),
Science Education Standards:
By the end of the 5th grade, students should know that:
- Stars are like the sun, some being smaller and some larger, but so far away that they look like points of light. 4A/E5
- The rotation of the Earth on its axis every 24 hours produces the night-and-day cycle. To people on Earth, this turning of the planet makes it seem as though the sun, moon, planets, and stars are orbiting the Earth once a day. 4B/E2bc
By the end of the 8th grade, students should know that:
- The sun is many thousands of times closer to the Earth than any other star. Light from the sun takes a few minutes to reach the Earth, but light from the next nearest star takes a few years to arrive. The trip to that star would take the fastest rocket thousands of years. 4A/M2abc

EARTH IN THE SOLAR SYSTEM:
- The Earth is the third planet from the sun in a system that includes the moon, the sun, eight other planets and their moons, and smaller objects, such as asteroids and comets. The sun, an average star, is the central and largest body in the solar system.
- Most objects in the solar system are in regular and predictable motion. Those motions explain such phenomena as the day, the year, phases of the moon, and eclipses.
- The sun is the major source of energy for phenomena on the Earth's surface, such as growth of plants, winds, ocean currents, and the water cycle. Seasons result from variations in the amount of the sun's energy hitting the surface, due to the tilt of the Earth's rotation on its axis and the length of the day.
ENERGY IN THE EARTH SYSTEM
- Heating of Earth's surface and atmosphere by the sun drives convection within the atmosphere and oceans, producing winds and ocean currents.
