Topic 8: Solar System


The moon orbits the Earth once every 27.32 days.

takes approximately 27 days for the moon to rotate once on its axis.

Thus, giving us our 8 moon phases

Depending on the time of day, we can see it rising, overhead, setting, or completely blocked from the view.

What was the point of this activity?

The point of this activity was to see how the moons rotation cause phase change and how it’s relationship with the sun affects all of that.

Explain how you would introduce this to your class?

I would explain this by first discussing the difference between rotation and revolution because sometimes students mix up the two. I would show them moon phases and ask them to guess what they were and how they knew. Then i would start the topic.

Where do you see a student having difficulty with this?

I could see difficulty happening with students mixing up waxing and waning and crescent and gibbous moons. I can see them also being confused on seeing a visual of a moon and having to determine whether it is setting, rising, and so on in relation to the position of the sun.

What changes or extensions could you do to this activity?

I would create a chart with the phases on it so they can see it as a visual. i would also look for a video that shows the rotation of the moon fast forwarded through the month so they can witness it moving.
