Describes the logic behind the development of Newton's law of universal gravitation. Beginning with Johannes Kepler and his three laws of planetary motion, content walks the reader through Newton's thought process and development of this...

A look at John F. Kennedy's goal for the United States, which was to send the first man to the Moon and to bring him safely back to Earth. Informational text and lesson plan for young scholars in grades 9-12.

Students observe representational images and use as evidence to describe how the Moon is visible in the day and night sky. The digital slideshow is used to provide students with the opportunity to observe and describe how the Moon can be...

Prepared by NASA, this site provides a detailed look at the Earth's moon. The menu tabs are divided into overview, photo gallery, and facts and figures.

Often when we see drawings of the Earth and the moon, they look really close together. Check out this cartoon series that helps illustrate the reality of this concept.

The learning module helps students gain a deeper understanding of gravity. Some topics explored are orbits, the mission to the Moon, and the first space walk. Activities and videos are included.

Through illustrated examples and interactive practice, students explore Newton's ability to relate the cause for heavenly motion (the orbit of the moon about the earth) to the cause for Earthly motion (the falling of an apple to the...

Students learn about the physical properties of the Moon. They compare these to the properties of the Earth to determine how life would be different for people living on the Moon. Using their understanding of these differences, they...

In this lesson, students will construct a scale model of the Earth-Moon-Mars system.

An image of "Hina te Fatou (The Moon and the Earth)", created by Paul Gauguin in 1893 (Oil on canvas, 112 x 61 cm).

[Free Registration/Login Required] Learn how the steady motion of the Moon around the Earth, and the phases created by the relative position of the Earth, Sun, and Moon, allow us to tell time by simply looking at the shape and...

This lesson explains how the moon affects tides on Earth and about the different types of tides.

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.

Discover facts about the Earth and the Moon with NASA scientist, Dr. Marc Rayman.

Students are asked to compare and contrast the earth and the moon.

[Free Registration/Login may be required to access all resource tools.] Describes the phases of the moon and what causes them.

This site provides a very interesting overview of our home planet, Earth. Content includes a focus on the atmosphere, the pull of gravity, and the active surface.

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.

"One Small Step, The Race To The Moon" is a clear presentation of the story of the Moon landing program that the United States conducted during the 1960's and early 1970's. After launching the presentation click on the phases of the Moon...

A collection of high-resolution images of space. Images "showcase the discoveries and excitement of planetary exploration, with a focus on the origin and evolution of the Solar System and the search for life".

Do you know what a solar eclipse is? Or how about a galaxy? Space Place has the answers to all your questions about space! Site includes information to explore about planets, satellites, moons, and much more. Also on the website are...

View a map of the Earth showing the day and night regions at this moment, or from the sun, the noon, the night side, and other points of view in this simulation. Illustrated.

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

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...
