The changing seasons have fascinated humans for centuries, captivating our senses and shaping our daily lives. From the warmth of summer to the chill of winter, understanding the reasons for seasons is a fundamental aspect of comprehending Earth’s dynamic systems. By exploring the intricate relationship between the Earth and the Sun, students can unlock the secrets behind the annual cycle of seasons and gain a deeper appreciation for the natural rhythms of our planet.
Teaching students about the reasons for seasons involves unraveling the complex interplay of Earth’s axial tilt, its orbit around the Sun, and the distribution of solar energy across the globe. As the Earth orbits the Sun, its axis remains tilted at an angle of approximately 23.5 degrees relative to its orbital plane. This tilt is responsible for the seasons, as it causes different parts of the Earth to receive varying amounts of sunlight throughout the year.
In my class, we take about one week to complete the “Reasons for Seasons” unit. Students investigate how the tilt of Earth’s axis and Earth’s movement in its orbit causes our seasons.
Students are introduced to the following concepts and terms: rotation, revolution, axis, tilt, seasons, angle of insolation, orbit, solar noon, solstices, equinoxes, etc.
Being that this topic is somewhat abstract, I like to use lots and lots of diagrams and animations. These tool helps students have a clearer understanding of how the tilt of Earth’s axis and Earth’s movement in its orbit have such an impact on us here on Earth.
