Seasonal Changes on Earth

In this lesson, students will be introduced to the concept of solar angle and how Earth’s tilt on its axis and revolution around the sun are responsible for seasonal changes in temperature, daylight hours, and the sun’s angle in the sky. Students will graph data taken from Scottsdale, Arizona and look for patterns in the number of daylight hours and the Sun's highest angle in the sky over the course of the year. Students will then relate these patterns back to the patterns Earth experiences seasonally.
