MS - ESS1.A - Patterns of Motion - FINAL (WND 1-2-14)

DCI: ESS1.A (A) Patterns of the apparent motion of the sun, the moon, and stars in the sky can be observed described, predicted, and explained with models.

Connections to Nature of Science: Scientific Knowledge Assumes and Order and Consistency in Natural Systems: Science assumes that objects and events in natural systems occur in consistent patterns that are understandable through measurement and observation.

PE: MS-ESS1-1 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 can be physical, graphical, or conceptual.]

The ideas in this standard are:

-patterns of the apparent motion of the sun can be observed, described, predicted, and explained with models

-patterns of the apparent motion of the moon can be observed, described, predicted, and explained with models

-patterns of the apparent motion of the stars can be observed, described, predicted, and explained with models

We have, in a separate module, asked several questions about seasons and eclipses.  Within this standard though, the PE seems to support only the use of a model to explain apparent motion, such as that of the sun across the sky throughout the day or the shifting position of the stars across the night sky.  

Possible Question Starters:

"The constellation Orion is visible from October to March in both hemispheres.  Which of the following movements best explains why it is not visible throughout the entire year?"

-correct answer - the earth is revolving along its orbital path

-incorrect answer - the rotation of the earth on its axis
