Total Lunar Eclipse and Moon Phases Lesson Ideas


This purpose of this blog entry is to offer some background information
to teacher’s trying to explain the Total Lunar Eclipse to their students.

What is a Total Lunar Eclipse?
A total lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon.

Why Does the Moon Appear Red During a Total Lunar Eclipse?
During a total lunar eclipse, the Earth blocks the Sun’s light from reaching the Moon.
The Moon is always a full moon during a total lunar eclipse and it never goes completely dark. The Earth’s shadow has two parts: the umbra and the penumbra. In a total lunar eclipse the moon passes directly behind the Earth’s umbra.  

The sunlight must pass deep through the Earth’s atmosphere, which filters out most of the blue colored light. The remaining light is a deep red or orange in color and is much dimmer than pure white sunlight. Earth’s atmosphere also bends or refracts some of this light so that a small fraction of it can reach and illuminate the Moon.
There will be a  total lunar eclipse on Oct. 8, 2014, followed by another on April 4, 2015 and the last total lunar eclipse of the current tetrad on Sept. 28, 2015.


In a related topic, you could discuss phases of the moon using Oreos. I would start by giving them Oreos and having them arrange the cookies in the way they think they should go and then label them.  After some input they could revise their thinking and their cookies.

Thank you so much for creating this resource! It is such a fun and engaging activity for my students, especially during distance learning.

My students loved this unit. I was able to present different elements of it throughout the month. It is hard to find interesting non-fictional, age-appropriate text for my students that they will enjoy. This was a great unit that aligned well for my students who have very different goals within the same group.

I am so impressed with this unit which manages to be distance learning and hands-on at the same time.  Really well thought out and engaging activities that allow students to practice each of the eight Science and Engineering Practices.  Really no prep for me!

The elephant article was excellent but I also thought the lab on dissecting a flower was broken down so easily, even telling me where to get inexpensive flowers!  This resource helped me teach this challenging standard in an engaging way.  Worth every penny!
