Relate the position of the Moon and Sun to their effect on ocean tides.

TEKS 8.8A: Components of the Universe: Stars, Nebulae, Galaxies, and H-R Diagrams*

Describe components of the universe, including stars, nebulae, and galaxies, and use models such as the Hertzsprung-Russell diagram for classification.

TEKS 8.8B: The Sun*

Recognize that the Sun is a medium-sized star near the edge of a disc-shaped galaxy of stars and that the Sun is many thousands of times closer to Earth than any other star.

TEKS 8.8C: Components of the Universe: Getting Information on Properties and Distances*

Explore how different wavelengths of the electromagnetic spectrum such as light and radio waves are used to gain information about distances and properties of components in the universe.
