To those of us who live on earth, the most important astronomical object by far is the sun. This article explains how the motion of the sun through our sky cause day and night, the passage of the seasons, and earth's varied climates.

The students will understand the relationship between the Earth and the sun and how this relationship affects observable phenomena on Earth, such as the seasons. The activity will help students learn about these concepts and will...

See what you know about the solar system by taking this brief interactive quiz and learning module.

A series of seven instructional, hour-long videos presenting Earth-science topics such as plate tectonics, oceans, climate changes, natural resources, the Sun, and the future of our planet. Closed captioning option provided for each video.

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.

The Space Environment Center (SEC) put together a slide show for use by teachers on Space weather. Begin with discussing solar emission and the sun itself. Then end with a summary of climatic effects of space weather, and a note on space...

An online website, from a historical perspective, of the study of the transit of Venus between the sun and the earth.

The Sun is the ultimate source of the energy that powers weather systems on Earth. Geomagnetic storms are sun-powered storms in the upper atmosphere, arising from energized particles that are periodically ejected by the Sun. Among other...

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...

This interactive activity from NOVA Online uses animation and graphics to offer a detailed explanation of the jet stream. A thorough account is given of the role played by the Sun's heat and Earth's shape and rotation, among other factors.

Learn about the rotation of the earth, the movement of the moon, and the position of the sun.

In this rotation activity, students investigate what causes day and night by participating in a classroom activity. Students will observe, question, and investigate how the relationship between the earth and sun causes day and night.

Learn about how Earth orbits the sun and how satellites orbit the Earth. Discover the different types of satellites such as GOES and POES and what they are used to monitor.

The sun's energy is the primary source of energy for all surface phenomena and life on Earth. Combined with the material of the Earth (including the molecules held close by the Earth's gravitational force called the atmosphere), this...

Omar helps his parents sell things at the market. Join him while he learns about the relationship of the Sun, Moon, and Earth.

An introduction to the Sun including its size and distance from the Earth, sunspots, flares and coronal mass ejections.

The unit contains lessons and a presentation that allow learners to explore the Sun through images and investigate how magnetism from the Sun interacts with the Earth's magnetic field during space weather events.

Learners will build a simple version of a magnetometer and use it to discover the types of areas of the Sun that have very strong magnetic fields. Students will then describe what the types of features associated with the Sun's strongest...

Understand where the sun is in the solar system and how big the earth, moon, and sun are.

Learn about the study of the Sun's influence on the solar system called Heliophysics. This site contains videos on topics like Space Weather, Solar Variability, the Heliosphere, Earth's Magnetosphere, and the Earth's Upper Atmosphere.

Learn about the Earth's revolution and rotation in this module.

Help Sarah Jane and her team put the solar system's planets back in order. Following the activity, read more about the sun, the Earth, and its moon, and then take a quick quiz to check for understanding.

In this fun activity, students will get creative with craft materials. They will figure out how to protect an "animal" and its territory from getting too hot in the sun. What will they build to keep their animals cool?
