A "Moonth" of Phases

A "Moonth" of Phases 



Question- 
What causes the phases of the moon? 

Answer- The position in which the moon is that, so it is lit by the sun, and/or darkened by earth.


Summary- 
In this experiment we observed what the phases of the moon would look like from two different points. We observed what the moon would look like from earth and what they would look like from space. We did this by using a flashlight and taking a small and large styrofoam ball. The smaller one represented the moon while the large one represented earth. There are 8 moon phases: Full moon, New moon, Waxing gibbous, First quarter, Last quarter, Waxing crescent, Waning crescent, and Waning gibbous. 

Full- A completely lit up moon
New-  A completely dark moon
Waxing Gibbous- A moon with a small dark part on the left 
First- A half lit moon, lit part on right
Last- A half lit moon, lit part on left
Waxing Crescent- A mostly dark moon, with a small lit part on right
Waning Crescent- A mostly dark moon, with a small lit part on left
Waning Gibbous- A moon with a small dark part on the right


Materials- 

1 large styrofoam ball- represents earth
1 small styrofoam ball- represents moon  
1 flashlight- represents sun 
2 toothpicks one to hold and other to hold moon 
A dark room 


Procedure- 

1. Go into a room with the lights off 
2. Attach one toothpick to the big styrofoam ball and the other to the small styrofoam ball 
3. Turn on the flashlight 
4. Use the small ball as the moon and the big one as earth 
5. Record Data 



The moon phases if viewed from space- 



 











The moon phases if viewed from a point on earth- 












In your model what represents Earth?Sun?Moon?
The sun was the flashlight. The moon was the smaller styrofoam ball and the earth was the bigger ball. 
How much of the lightened part of the ball did you see when facing the ball?
The half that was facing the light/sun. 
Which drawing represents a full moon? A new moon? Waxing Crescent? A waning crescent?
The full moon is the one completely lit. Waxing crescent is the moon with the crescent on the right. The waning crescent is the crescent on the left side. 
How much of the lightened part of the ball did you see after each turn?
After each part you saw more and more but after a few turns you started to see less. 
How much of the ball's surface was always lit?
There was no amount because at one point the ball was completely dark  
How well did making a model help you understand the phases of the moon?
It helped me a lot because I could physically see how much was lit or in darkness 
What are some disadvantages?
The lighting or darkness could be a bit off because the models are not scale or proportional.

  1. Tyler,
    You set up your blog post very neatly and I like the images that you included. However, the analysis and conclusion are missing from this post even though you included a summary.
