HMS-ESS1-1 | Earth-Sun-Moon Cycles
Develop and use a model of the Earth-Sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the Sun and moon, and seasons.
Clarification statement: Examples of models could include physical, graphical, or conceptual models.

NGSS Dimensions
Performance expectation MS-ESS1-1 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Developing and Using Models
- Develop and use a model to describe phenomena.
- ESS1.A: The Universe and Its Stars
- Patterns of the apparent motion of the Sun, the Moon, and stars in the sky can be observed, described, predicted, and explained with models.
- ESS1.B: Earth and the Solar System
- This model of the solar system can explain eclipses of the sun and the moon. Earth’s spin axis is fixed in direction over the short-term but tilted relative to its orbit around the sun. The seasons are a result of that tilt and are caused by the differential intensity of sunlight on different areas of Earth across the year.
- Patterns
- Patterns can be used to identify cause and effect relationships.
