This page provides basic information about the causes of the phases of the Moon. A good diagram shows the lit portion of the Moon as seen from Earth through one complete Lunar cycle.

This resource provides information about the lunar phases.

This lesson will introduce the phases of the moon and why the moon appears to change shape in the night sky throughout the month.

An interactive activity where students observe the different phases of the moon. Activity is part of a lesson plan that includes background information, instructions, and quiz.

Students use an interactive model to gather evidence about the visible Moon's changing pattern over 30 days in this resource from Astronomy Education at the University of Nebraska-Lincoln. They use this evidence to record and make...

Bill Nye explains the phases of the moon with an experiment using a baseball, a lamp on a table, a dark room, and a stool or chair that swivels. As the person moves around, the changes in reflected light show the phases of the moon. The...

In this TI InterActive! activity, students study the phases of the moon, plot the fraction of the moon showing each day in a month, and fit the data with an appropriate trigonometric function.

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

In this lesson plan, 4th graders use their bodies to model the day/night cycles of the Sun and Earth. Next, they discuss the moon's role in the solar system and explore the eight phases of the moon by acting out a story. Finally, a song...

A collection of ten hands-on science experiments for the entire family that will help you understand concepts in astronomy. Make an astrolabe, find the size of the sun and moon, build a lunar settlement, find out about meteoroids, shadow...

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.

"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...

In this astronomy classroom activity, students will investigate how shadows create the phases of the moon. Students will record the phases of the moon.

This activity is designed to allow students to observe and recognize the phases of the moon. They will develop a better understanding of the relationship between the position of the earth, moon and sun and how that affects the area of...

Students observe, identify, and describe how the Moon appears to change over the course of a month. They engage with a media slideshow of real-life images to describe how the Moon appears to change in a predictable pattern each month. It...

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...

A slideshow and a short multiple-choice quiz on the moon. It discusses the moon's phases, its rotation, and characteristics of the moon.

Explains the design of a simple device that shows the progress of the phases of the Moon on its 29 1/2 day orbit around the Earth.

Online calculator that posts up-to-the-minute phase of moon. Instructions are provided through a link on how to add this feature to your own web page.

Hands-on activity allows children to learn the phases of the Moon by creating their own flip book.
