Objective
By the end of this lesson, the student will be able to understand the concept of seasons and explain the factors that influence them.
Materials and Prep
- Pen and paper
- Access to the internet or reference books
- Prior knowledge of basic Earth Science concepts
Activities
-
Research and discuss the tilt of the Earth's axis.
Have the student find information about the Earth's axial tilt and how it affects the seasons. Encourage them to take notes and ask questions if they need clarification.
-
Create a visual representation of the Earth's orbit around the Sun.
Using a pen and paper, have the student draw a simple diagram showing the Earth's orbit around the Sun. Label the positions of the Earth during each season and explain why the distance from the Sun does not cause the seasons.
-
Observe and discuss the changes in daylight hours throughout the year.
Encourage the student to keep track of the sunrise and sunset times for a specific location over a few weeks or months. Discuss how the changing daylight hours contribute to the different seasons.
Talking Points
- "The Earth's axis is tilted at about 23.5 degrees."
- "During summer, the hemisphere tilted towards the Sun receives more direct sunlight, resulting in longer days and warmer temperatures."
- "In winter, the hemisphere tilted away from the Sun receives less direct sunlight, leading to shorter days and colder temperatures."
- "The Earth's orbit around the Sun is slightly elliptical, but the distance from the Sun does not cause the seasons. The tilt of the Earth's axis is the primary factor."
- "The changing daylight hours throughout the year are a result of the Earth's tilt and its orbit around the Sun."
