Nicolaus Copernicus developed the theory of Earth's orbit around the sun demonstrated in this science simulation.

Students perform many inquiry activities related to Earth's orbit. Included are recording daily temperatures, observing the sun's path over several weeks, tracking sunrise and sunset times, and angle of sunlight. Diagrams make lessons...

[Free Registration/Login may be required to access all resource tools.] Discusses the motion of the Earth with its day and night cycle, the seasons, the Earth's orbit around the Sun, and its year-long cycle.

The BBC provides a general overview of the planet Earth. Content includes statistical information, a focus on the four seasons, moon information, and more.

This interactive activity from the Adler Planetarium explains the "reasons for the seasons." Featured is a game in which Earth must be properly placed in its orbit in order to send Max, the host, to different parts of the world during...

For the first time, NASA scientists have generated a full image of the sun, front and back, using twin orbiting satellites. The new view of Earth's star will allow for the study of solar weather events like coronal mass ejections that...

[Free Registration/Login may be required to access all resource tools.] Orbital motion and why it occurs, and the orbits of the Earth around the sun and the moon around the Earth.

Experience a science simulation illustrating the Copernican theory of Earth's orbit around the sun.

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 site from NASA helps in explaining a barycenter. "In the case of the Earth and the Sun, both bodies actually revolve, or spin, around the center of the mass between them. This point is called the barycenter."

This lesson will analyze the role of the sun and moon relative to the earth's orbit. It is 3 of 4 in the series titled "The Sun and Moon."

This lesson will analyze the role of the sun and moon relative to the earth's orbit. It is 4 of 4 in the series titled "The Sun and Moon."

Move the sun, earth, moon, and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it.

An interactive simulation that teaches about gravitational force, circular motion, and astronomy by manipulating the sun, earth, moon, and a space station to observe the effects of gravity and orbital paths. This simulation can either be...

A university-level course that looks at the structure of the solar system, the sun, the planets, and other bodies in space. Includes course readings, assignments, and study notes.

Students model the interaction of the earth and the sun. The activity is designed for the playground. You will need chalk, but all the other worksheets are provided.

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

This site is astronomy for kids and teachers! Here students can learn about the planet Earth of the Solar System including fun facts, mass, day, year, and distance from the Sun.

Teach the concept of scale models and the size of the solar system through this extensive lesson plan. Students will learn about scale models, estimate which objects to use to create a scale model of Earth and Sun, and figure out how far...

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...

An excellent and thorough answer to the often asked question about high tide "bulges" on the side of Earth facing away from the Moon or Sun.

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