Explain Why There Are Different Phases of the Moon

The eight Moon phases. To remember the in-between phases youll need to understand these terms.

Phases Of The Moon 8th Grade Science

This is all that is needed to create the phases of the Moon.

. The phases occur because the Sun lights different parts of the Moon as the Moon revolves around the Earth. Observing the Moon Grades K-6 - Students identify the Moons location in the sky and record their observations in a journal over the course of the Moon-phase cycle. This causes our Moons phases.

Many people believe the Moons phases are caused by the Earths shadow. This ball will represent the Moon. Phases of the Moon explained Phases of the Moon As our moon travels through space orbiting our planet we see it in its different phases at different times and if you mouseover the graphic small moons arranged around the earth in the picture below left you will get an explanation for what you see in the box on the right.

Phases of the Moon The Moon doesnt emit give off light itself the moonlight we see is actually the Suns light reflected off the lunar surface. This phase is called a new moon. Your head is the Earth.

The diagram below on the right is one you typically see in books. And the Sun well where is the Sun. So as the Moon orbits the Earth the Sun lights up different parts of it making it seem as if the Moon is changing shape.

In actual fact its just our view of it thats altering. Different Phases Of The Moon New Moon. If the Moon walks round the Earth then the person who is the Earth will see more or less of the Moon illuminated.

When the moon is between the sun and the earth we dont see the moon new moon because only its backside is lit up by the sun. In the Northern Hemisphere we see the waxing crescent phase as a thin crescent of light on the right. But the moon still looks a little different every night.

The illumination is brighter and the Moon seems to be growing larger. This phase is between the first quarter phase and a full moon. Because the Moons orbit is not perfectly circular its distance from Earth and its speed in orbit both change slightly throughout the month.

For instance the image below shows the angle at which we see the Moon during its Waxing Crescent phase. The four phases of the moon are. We see the first quarter phase as a.

After the first quarter comes the. Just like the Earth half of the Moon is lit by the Sun while the other half is in darkness. When the moon rotates around the earth the lit-up part turns with it resulting in different phases visible from the earth.

8 Phases of Moon Explained. Have participants take a couple minutes and use the Moon ball to try to show why the Moon looks like it does. This is when the lighted side of the Moon faces away from the Earth.

Others think it is clouds passing in front of the Moon. Moon Phases Grades 1-6 - Students learn about the phases of the Moon by acting them out. The first half moon after the new moon is called the first quarter because at that point the moon is one-quarter of the way through its monthly cycle of phases.

Half of the Moon is always illuminated by the Sun. Lunar phases on the other hand are caused by the position of the moon in relation to the sun. We only see the part of the moon that the sun is shining on.

These differences are explained by lunar phases which impact the way the moon appears from Earth over approximately one month. There are eight phases of the Moon which repeat every 295 days. However four main moon phases are there we also call them the Lunar Phases.

Other Moon Phases Besides the new moon first quarter full moon and last quarter phases there are a couple of other lunar phases. We cannot see the Moon when it is a new moon. The moon orbits around the planet Earth and the Earth orbits around the Sun.

Most of the near side is in view from Earth appearing brighter in the sky. We always see the same side of the moon because as the moon revolves around the Earth the moon rotates so that the same side is always facing the Earth. Essentially its just a transition between two phases.

Waxing means growing or expanding in illumination and waning means shrinking or decreasing in. After the first quarter phase the Moon becomes fuller during the waxing gibbous phase. This is where you start to see the backward C like shape.

That means the reason we see different phases of the Moon here on Earth is that we only see the parts of the Moon that are being lit up by the Sun. Crescent gibbous waxing and waning. In 30 minutes they will act out one complete 30-day Moon cycle.

Phases of the Moon. The moon appears to us to have different phases because as it rotates around the earth different parts of it are lit up by the sun. Firstly the moon keeps changing its shape with 4 distinct moon phases that depend on the position of the moon and also on the position of the Earth.

New Moon A new moon is usually not visible to the naked eye as only the unlit portion of the Moon is exposed. When we see a portion of the moon shadowed and invisible it is not because of the earths shadow but because the dark portion of the moon is. Youll notice that when the Moon is between the Sun and the Earth an eclipse occurs - for why we dont actually see an eclipse every new Moon see below.

Crescent refers to phases where the Moon is less than half-illuminated while gibbous means more than half is illuminated. Sometimes the entire face glows brightly. It will therefore appear dark and unlit.

The Moons rate of rotation around its own axis though always stays the same. But because our Moon is constantly orbiting the Earth we see the illuminated or lit-up part from different angles throughout the month. During the new moon the side facing Earth is dark.

The phases we see result from the angle the Moon makes with the Sun as viewed from Earth. Dont let it confuse you. New moon when the moon is not visible from Earth First quarter moon when - after a new moon - one half of the moon is visible Full moon when all of the moon is visible from Earth Third quarter moon when - after a full moon -.
