Why do some regions experience full-time heat while others are reckoning with frigid temperatures and snow? And why are the seasons reversed in the two hemispheres? Rebecca Kaplan explains how the shape of the Earth's orbit around the...

Join Audrey on her learning adventure as she discovers how the Earth's rotation causes day and night.

A video and a short multiple-choice quiz on how the Earth's tilt on its axis, its rotation, and its orbit around the Sun give us a 24-hour day, a 365-day year, and our seasons.

This season simulator takes Earth through an entire year cycle allowing the viewer to observe the tilt of the Earth and the intensity of the sunlight.

A worksheet regarding the path of the Sun around the Earth and the Earth's tilt on its axis.

An explanation about the rotation of the Earth and why the Earth has seasons.

[Free Registration/Login Required] An interactive animation demonstrating the Earth's tilted axis and how that causes the seasons. Also included on the site is a short quiz on the topic.

A KWL activity combined with a demonstration model. Young scholars record their ideas and questions about why we have day and night. They then shine a flashlight (the Sun) on a rotating styrofoam ball (the Earth) and record their...

In this activity, students' will explore how the tilt of the earth's axis results in different amounts of solar radiation at different times of the year, causing seasons. They will simulate the earth's warming using a light bulb that...

Nutation is a small cyclical motion superimposed upon the steady 26,000-year precession of the Earth's axis of rotation. It is mainly caused by the gravitational effect of the 18.6-year rotation period of the Moon's orbit. The main...

In this lesson, students will discuss, define, and demonstrate the Earth's rotation and revolution around the sun in a counterclockwise position. They will be able to predict seasons based on the amount of light that hits the Earth.

The popular television show, Game of Thrones, and the novel series it is based on, A Song of Fire and Ice, take place in another world. Joe Hanson explores possible scientific explanations of the phenomena exhibited on the show. [8:01]

Especially for kids, the Weather Dude provides a simple explanation of the seasons. Includes a music clip titled "Circle of Our Four Seasons," and suggested lesson plans and school assignments.

A slideshow and a short multiple-choice quiz on the topic of seasons and how they are caused by the Earth's rotation and orbit.

Over the course of the school year, students collect weekly data about the sun's position at a specific time of day, resulting in creating a figure "8" that shows the path of the sun called an analemma.

This interactive globe allows you to get any view of the earth by entering latitude, longitude and season criteria.

An insightful website from NASA that presents a series of different questions about the rotation of the Earth.

[Free Registration/Login Required] This flipchart illustrates a view of the earth from space and how day and night happens.

[Free Registration/Login Required] In this flipchart students will understand how the Earth rotates during a 24 hour period giving us day and night.

[Free Registration/Login Required] Students read about how the tilt of the Earth on its axis affects sunrises and sunstes. A question sheet is available to help students build skills in reading comprehension.

A slideshow exploring Earth's rotation and revolution around the sun. Learn that because of Earth's axis tilt we experience the seasons!

Learn how Greek mathematician Eratosthenes used geometry to estimate the circumference of the Earth.
