Phases of the Moon: How to determine cyclically changes of the visible lunar surface (iStage 1)

Mondphasen: Zyklische Veränderungen der sichtbaren Mondoberfläche berechnen (iStage 1)

Have you ever noticed that, regardless of which place on Earth we are, we all see the same shape of moon on the same day? Have you ever noticed that the illuminated part of the moon changes sequentially and cyclically?

In this teaching unit, we’d like students to understand how the relative positions of the sun, earth and moon influence each phase of the moon, how to determine this phase for a given day, and how to calculate the percentage of its illuminated part.

This unit is recommended for students age 14 to 16 as prior knowledge in trigonometry and astronomy is required.

Please find the additional material mentioned in the text below. The project is taken from the brochure ‘iStage: ICT in Science Teaching’ from the unit ‘From Bicycle to Space’. ou can download the complete brochure here (printed version no longer available). The material has been developed by 22 teachers from 15 countries. The project has been supported by SAP.
