Students download sunrise and sunset data along with moon phase data, and graph these data sets together in a spreadsheet in order to visualize the cycles of the seasons and the moon.

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...

Find out what the seasons are and how they change. Through the use of excellent graphics, content explores the Earth's orbit around the sun and how sunlight reaches the earth at equinox and the winter solstice.

In this set of activities, the path the Sun takes in relation to the Earth is tracked by students on two days, with three months in between them. They will develop an understanding of what causes the seasons as they examine the effects...

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.

The following lessons help students from grades 6-8 understand sleep and circadian rhythms. Lesson topics iinclude: day and night, seasons, sundails, clocks, sleep and sleep patterns and sleeping in space.

Students graph data reflecting time of day and length of shadow, and then draw conclusions about Earth's seasons and position in relation to the Sun.

A brief explanation of the Earth's rotation around the Sun and how it relates to the amount of sunlight the Earth receives, and to the seasons. Includes two questions for students to respond to.

[Free Registration/Login may be required to access all resource tools.] Learn how and why seasons occur.

For this activity, young scholars create a small model of the Earth using a styrofoam ball and a skewer. They then explore the relationship between the Earth and the Sun (a flashlight) to understand why it is hottest at the Equator, and...

[Free Registration/Login Required] This flipchart explores the relationship between the sun and earth and how the seasons happen. Vocabulary of the equinox, solstice, etc. is included.

In the school courtyard, learners will measure the apparent path of the sun across the sky using a toilet plunger. Students will then generate questions as to why the sun appears to move, and what is really happening in the process. We...

A student-directed tutorial showing all aspects of seasons, including Earth's tilt position in relation to the sun, photos of typical weather during that season, and some informational text to support the visuals.

In this instructional activity, 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...

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

Learn about the four seasons, when they occur in the northern and southern hemispheres, and why the seasons change as the Earth rotates around the Sun.

In this activity, use seasons to determine your location. Click on the different dates to view the earth's shadow at different times of the year from the sun's position.

A poem, written in Chinese with an English translation, that describes the summer sun, the beach, and the sea.

[Free Registration/Login Required] The history of our calendar is presented through the passage of time with complete cycles of seasons in ancient history providing a starting place. Complete cycles of seasons are discussed and the...

The focus of this series of lessons is to engage students in an exploration of the world around them. The emphasis is on inquiry as students learn about the earth, sun, light, shapes and more.

Choose from four animations that show why the amount of daylight is different throughout the year. Topics include the seasons, the sun's apparent path, and days and nights over the year.

Dozens of statistical terms are defined and illustrated in this glossary.

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.
