The EJS Phases of Moon model displays the appearance of Moon and how it changes depending on the position of Moon relative to Earth and Sun. The main window shows Earth (at the center) and Moon, as well as a circle tracing out Moon's orbit. Sun is far to the right in this picture and therefore the right side of Earth and Moon are bright while the left sides are dark.  By using the Options Menu the Moon View window shows the appearance of Moon as seen from Earth  when Moon is in the position shown in the main window.  You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.

The EJS Phases of Moon model includes three supplemental documents (see below) that include a middle school lesson plan, a college level worksheet, and the student version of the program.

EJS Phases of Moon model was created using the Easy Java Simulations  (Ejs) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.   Double clicking the ejs_astronomy_MoonPhases.jar file will run the program if  Java is installed.  Ejs is a part of the Open Source Physics Project and is designed  to make it easier to access, modify, and generate computer models.  Additional Ejs  models for astronomy are available.  They can be found by searching ComPADRE for  Open Source Physics, OSP, or Ejs.

Please note that this resource requires at least version 1.5 of Java (JRE).

I. ENGAGEMENT
i especially liked the tennis ball and torchlight to situated the learning to a real world example, a lot of teachers will benefit from this kind of insightful lesson strategy, instead rushing into the powerpoint and talk and talk.

great lesson package!

4. The Physical Setting

4A. The Universe
  • K-2: 4A/P2. The sun can be seen only in the daytime, but the moon can be seen sometimes at night and sometimes during the day. The sun, moon, and stars all appear to move slowly across the sky.
  • K-2: 4A/P3. The moon looks a little different every day but looks the same again about every four weeks.
4B. The Earth
  • 6-8: 4B/M5. The moon's orbit around the earth once in about 28 days changes what part of the moon is lighted by the sun and how much of that part can be seen from the earth- the phases of the moon.

11. Common Themes

11B. Models
  • 6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.

Phases of Moon Model:

Is Based On Easy Java Simulations Modeling and Authoring Tool

The Easy Java Simulations Modeling and Authoring Tool is needed to explore the computational model used in the EJS Phases of the Moon Model.

relation by Mario Belloni
Covers the Same Topic As ASPIRE: Lunar Phases

This is an inquiry-based tutorial for grades 6-9 on the topic of moon phases. Students work with partially-competed diagrams to understand how the Earth's rotation, moon's orbit around Earth, and reflected sunlight all come together to produce a "changing" moon.
