Reflection: Rigor Seasons & Tides - Section 4: Part 2 (Exploration/Simulation - Organization - Illustration)


The Earth-Sun system being studied in this lesson lends itself to students building a systems model to help explain seasonal variation on Earth related to the Earth's tilt and its revolution around the sun.

It would be a good idea if you have a globe and a light source to create this model in the classroom to demonstrate to students the phenomena. Even better would be to have students create the model themselves so that they take more ownership of their learning.

I would follow this up later in the lessons on the Inner and Outer Planets to compare their position on their rotational axis in relationship to earth so that students build an appreciation for the differences between planets.

Seasons & Tides

Unit 8: Where Is Earth In Space?
Lesson 3 of 10

Objective: SWBAT 1) explain how the movements and distances (perigee, apogee) between Earth and Moon produce tides including the relationship between phases and tides and tidal bulge and rate of lunar revolutions and 2 ) Explain how revolution, rotation, and precession of the Sun-Moon-Earth system produce changes in the solar angle of incidence (altitude, azimuth) that result in seasons (solstices and equinoxes) and changes in the length of a day, month (sidereal and synodic lunar month), and year.

Big Idea: Students create an Earth-Sun-moon model to explain seasons and tides.
