In this video we view the phases of the moon as seen from earth. As each phase is shown, its name is reviewed and explained. A section of repeating sunrise/sunset cycles to show how the moon changes position in relation to the sun throughout its cycle.
In the digging deeper section we look at a few logical reasons as to why lunar phases can’t be caused by Earth’s shadow as so many people believe. Next we look at the geometry of the moon in relation to the sun and Earth during each lunar phase: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning crescent.
In the teacher to teacher section I’ll give you a few hints and helps to show you more how to use this free computer program called Stellarium which will turn your classroom computer into a planetarium. This video uses Stellarium, a free, open-source computer program used by many professional Planetariums around the world.
The video includes three parts:
1) Main content, directed to the learner
2) Digging Deeper a more in-depth look at the topic
3) Teacher to Teacher—hints and helps about how to use the featured computer program, Stellarium.
Additional videos and written materials on this topic are available, however these are optional; this video stands alone. Engaging Science Labs produces materials that are useful for classroom or homeschool environments.
• The Moon’s phase is due to its location in relation to the sun and Earth.
• The Moon’s phase determines its rise and set times.
• The Moon’s phase is not caused by Earth’s shadow
• The Moon spends half of its time in our daytime sky and half in our nighttime sky
