In the 'Tracking Celestial Patterns' word sort activity aligned with ESS1.A, students explore the predictable motions of the sun, moon, and stars. By sorting terms like 'sunrise,' 'full moon,' and 'constellations' into categories such as the sun's motion, moon's motion, and star patterns, students gain an understanding of how celestial bodies move and change over time. This hands-on activity encourages observation and prediction, fostering a deeper appreciation for the universe's rhythms.
