Let's have a look!!


The 8 phases of the Moon

             

Phase 1 - New Moon - The side of the moon that is facing the Earth is not lit up by the sun. At this time the moon is not visible. 

Phase 2 - Waxing Crescent - A small part (less than 1/2) of the moon is lit up at this point. The part that is lit up is slowly getting bigger.

Phase 3 - First Quarter - One half of the moon is lit up by the sun at this point. The part that is lit up is slowly getting bigger.

Phase 4 - Waxing Gibbous - At this time half of the moon is lit up. The part that is lit is slowly getting bigger. Waxing means to slowly get bigger.

Phase 5 - Full Moon - The side of the moon that is lit up by the sun is facing the Earth. The entire moon is lit up at this point.

Phase 6 - Waning Gibbous - The moon is not quite lit up all the way by sunlight. The part of the moon this is lit is slowly getting smaller. Waning means to slowly get smaller.

Phase 7 - Last Quarter - Half of the moon is lit up but the sun. The part that we can see lit up is slowly getting smaller.

Phase 8 - Waning Crescent - A small part of the moon is lit up at this point. It is getting smaller by the minute.

Further Activity



1.  Use 28 pieces of paper of the same size.
2.  Draw a circle of the centre of each paper. The circles must be of the same diameter.
3.  Number the papers 1 to 28.
4.  Colour the circle on paper number 1 according to the shape of the Moon that you
     observed on day 1 (refer to the “Lunar Calendar Chart”).


5.  Repeat step 4 for all papers.
6.  Arrange and then staple on the right side of the papers according to the date of the
     lunar calendar.

7.  Flip the pages as fast as you can until you see the changes of the phases of the Moon.

It is just a phase




What do I want?
To observe the phases of the Moon.

What do I need?
Cardboard
String
Glue
Marker pen






Ruler


Scissors



What do I do?

1.   Cut a circular cardboard 30 cm in diameter.

 









2.   Fold the circular cardboard into four equal segments. Then, divide each 
  segment into seven and unfold it. Number them from 1 to 28 
  counterclockwise. This is your “Day of Observation Chart”.












3.   Make a small hole on the top of the chart. Tie a string and hang the chart. 
 










4.   Observe the shape of the Moon and draw it on the segment of the “Day of

      Observation Chart”.

5.   Repeat your observation every night for 28 nights and record your 
   observation on the segment according to the day of observation.
6.   Cut a circular cardboard 10 cm in diameter to form a “Lunar Calendar 
      Chart”.
7.   Repeat step 2.
8.   Paste the “Lunar Calendar Chart” on the “Day of Observation Chart” so   
  that segment number 15 on the “Lunar Calendar Chart” corresponds to full 
  moon on the “Day of Observation Chart”.












9.   The numbers on the smaller card represent the lunar calendar.

10. From the “Lunar Calendar Chart” identify new moon, crescent moon, 

      half-moon and full moon.


What do I find?

1.  On what day of the lunar calendar can you see full moon?

2.  On what days of the lunar calendar can you see half-moon?
3.  What is the difference between the first crescent moon and the second crescent 
     moon?

What do I conclude?
There are (four / eight) major phases of the Moon in one month of the lunar calendar.

Phases of the Moon




What is the phase of the moon?
The changing shape of the bright part of the Moon that we see is called its phase. 
















What causes part of the Moon to be lit up?
The moon is illuminated because it reflects the light from the sun. The part of the moon facing the sun is lit up. The part facing away from the sun is in darkness.















What causes the different phases of the Moon?
The phases of the Moon depend on its position in relation to the Sun and Earth. As the Moon makes its way around the Earth, we see the bright parts of the Moon's surface at different angles. These are called "phases" of the Moon.
 


























What are the different phases of the Moon called?
The phases of the moon work in a cycle starting with the new moon.

There are eight phases of the moon
The phases are named after how much of the moon we can see, and whether the amount visible is increasing, or decreasing each day.


 

It takes our Moon about 29.5 days to completely cycle through all eight phases. This is known as a Lunar month





The Phases of the Moon

As the moon circles the Earth, the shape of the moon appears to change; this is because different amounts of the illuminated part of the moon are facing us. The shape varies from a full moon (when the Earth is between the sun and the moon) to a new moon (when the moon is between the sun and the Earth).
