This is a very simple demonstration and isn't intended to exactly represent how the sun, moon and earth would actually 'move' in relation to each other. However, the moon's orbit around the earth is represented correctly and shows why we see the changing areas of light and shade on the moon's surface as the moon's position relative to the sun changes throughout the lunar month.

There is something wrong with your face.

It's a demo for elementary school age children with nothing more than a lamp the teacher already owns, a common pencil, and a cheap foam ball. The point is to show the phases of the moon has to do with the different angles earth sees the day and night sides of the moon, rather than earth casting a shadow or something. Fine details can come later, when kids can use diagrams and their imagination.

As well as the moon orbiting the earth once every 4 weeks, the earth is also rotating, so we see the moon in different positions from one day to the next.

Much like how a rainbow comes from refracting light from the sun, ice crystals or water droplets can refract moonlight. This happens in a small range of angles, which forms a ring around the moon.

If you think you know all about the moon, you'll be able to tell me what the period of a lunar day is? In other words, what is the time between one sunrise and the next?

In this demonstration that is what will happen, but do you know why this doesn't happen every lunar cycle in the real situation?

There is a theory. Lmao

@@Sue-j1y What is the issue you have with the demonstration? Do you not understand that it's just a simple simulation to explain why we see the changing areas of light and shade on the moon's surface throughout the month?

A physical model like this is often better than a fancy animation.

Is it not obvious as to what causes solar and lunar eclipses?

Yes! When the moon is a very thin crescent, the 'earthshine' on the moon's nearside surface is very obvious, especially through binoculars or a telescope.

Clearly, you were first in line when STUPID was being handed out. The moon orbits the earth and as it does so, we on earth see the moon's changing orientation with regards to the sun, hence why we see the changing areas of light and shade (phases) on the moon's near side surface - 100% FACT. The contrary opinion of an unhinged fool such as yourself won't change this.

your face is a lie

lol

Up until watching this video, did you actually have no understanding as to what causes the changing areas of light and shade on the moon's surface? Surely you knew that the moon orbits the earth? This is about the only physical understanding someone needs to know to put 2 and 2 together to get the 'phases'.

A simple, physical model like this is often better than a fancy animation.

Your question makes no sense.

I really don't understand what you're trying to say in your comment? Do you not agree with the explanation in this video, that the moon's changing phases are as a result of the moon orbiting the earth and the moon's change in orientation with regards to the sun?

wat. Hold a ball out toward the moon while in sunlight and the shadow pattern on the ball and the moon will be identical.

@ I'm not saying that. I'm just pointing out that in the visual demonstration it can be seen that the edge of the moon, due to the influence of the light bulb beam that represents the sun, shows a straight edge and not a curved one as we see in the sky. By this I mean that what we think we see is not really so.

@@Ravaxr watch carefully as the ball from the moon's point of view begins to overlap the sun. Its edge does not curve as we can see in the sky. This phenomenon is only visible on the flat side. It is important that you try as well as Mrs. Only the bulb has a different shape in the lower part, therefore it is only visible in the upper part, where the bulb has a rounder shape. Can you see it yet? If the lady gave something flat, there would be a curve. It is because the rays are curved on the round part so that they form a straight line instead of the classic curvature

Jews science

@NitishDiwakar Romans 2:28For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: 29But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.

Not necessary to demonstrate moon phases to 5th graders.

This model DOES 'demonstrate tidal locking'. At what point in the demonstration does the same side of the moon (ball) not face the earth (her head)?

@@sailorman8668do the moon and the earth rotate in the video? That’s what tidal locking is, they both rotate while still only one side of the moon is visible on earth.

@@mistermaykul There are limitations to the demonstration obviously. The earth (her head) does not rotate, but as in reality, the same side of the moon (the ball) is always facing earth. Can you not see in the demonstration, that the same side of the moon (the ball) is facing earth (her head) at all times during its orbit around her head?

This model is meant for a class of elementary school kids using cheap materials to get the basic idea of the moon's phases being the day/night cycle of the moon seen from afar. The bill of materials is a pencil, a lamp with the shade taken off, and an 80 cent foam ball. Considering how stretched thin the budget is for a lot of schools, and how many teachers end up having to buy their own supplies, it's remarkably efficient. It doesn't need to demonstrate tidal locking, that's for high school students, and at that age you don't need props like these.

The moon rotates on its axis, too. Its orbital speed around earth is identical to earth's rotational speed. Many moons in the solar system have this relationship to their parent planet.

@ The moon never spins. Well done R0ckefeller indoctrination camps. Well done.

@@lifeontheroad_ If you actually think the earth is flat, then clearly, it is YOU who as been to 'indoctrination camp'. The moon exhibits the phenomenon of 'synchronous rotation', where the time it takes to complete one revolution is the same as the amount of time it takes to complete 1 orbit of the earth, hence why the same side of the moon always faces earth. The synchronous rotation is due to 'tidal locking' and is very common with the other moons in the solar system and their parent planets. And with regards to your use of the phrase 'dark side of the moon', why mention anything about this side of the moon being 'dark', when it receives just as much sunshine as the side that always faces earth? Just out of interest, what causes the changing areas of light and shade on the moon's surface throughout the month, if it's not because of the explanation given in this video?

@@lifeontheroad_ just explained how it spins ,keep dodging the argument

@@delayedcreator4783 Where is the argument that I dodged? Someone made a statement and I replied. The moon does not have an axis nor does it spin. It does rotate around the earth with only ever showing one side. The same side as one would have seen 6,000 years ago.

Why did this 'single experiment' save you from becoming a flat earther, when there is a multitude of other evidence that proves that the earth is a spherical rotating planet that orbit the sun? Why did you not mention that solar and lunar eclipses also throws the flat earth model into the toilet?

God had NOTHING to do with the creation of the solar system. You seem to be somewhat of an indoctrinated fool.

If you don't think the explanation given in this demonstration is correct, perhaps you can convey to everyone what you think causes the changing areas of light and shade on the moon's surface throughout the month? And hopefully, YOU don't end up being the one who is 'embarrassing'.

@sailorman8668 well I'm definitely not arrogant enough to think understand this place, so no I won't explain how it works. However it's easy enough to see doesn't work like this. Just live life and pay attention to the sky as you Iive, you will see the moon in all it's phases with the sun in various positions in the sky. Haven't you seen the moon during the day? Have you not noticed how the moon's phases have nothing to do with the sun's position in the sky??? Take some time with it, it's right there in front of you. Look at the moon during the day, wherever it is in it's cycle assess the angle and apex of the "shadow" on the moon, then draw a line with your finger 90° from that line. It (in my mind) should take your finger straight to the sun, but most often it does NOT. See she was only able to make her moon full by putting her sun at her back. Yet I can't count how many times I've seen a full or at least nearly full moon during the day... this is massive massive contradiction of the heliocentric model. 🙏

@@Memry-Man Next time you see the moon in the daytime, go stand in the sun and hold a ball up to the moon. The sun will light up the ball with exactly the same terminator as the moon. ua-cam.com/users/shorts7bylhcM8yMc?si=6PUcwZ6qOjf65SDF

@@Memry-Man Thanks for your reply, but unfortunately it has only helped to show just how ignorant you are about how the moon should appear with reference to the sun's position in the sky. You obviously lack something in your understanding of the visual aspect of the moon's illuminated surface, not realizing that the sun's position in the sky casts light on the moon's surface in exactly the correct way. It's almost as if you're claiming that the ILLUMINATED part of the moon's surface isn't being ILLUMINATED by the sun? Please explain to everyone then, if it's not the sun that is ILLUMINATING the moon's surface, then what is? It's rather embarrassing for you, that we need to explain to you, that the ILLUMINATED portion of the moon's surface is due to SUNLIGHT being cast onto that part of the moon's surface, which is why the 'dark' (not ILLUMINATED) area on the moon's surface is due to the fact that the sun's light isn't hitting this part of the moon. You appear to have the mind of a child, yet I'm assuming you're actually an adult? Perhaps you have a learning disability or some type of cognitive impairment and you have a very hard time in understanding simple concepts? It's rather sad that you've stated that you 'won't explain how it works', when in fact it's not a matter of deciding to refrain from giving an explanation, but actually not having a clue what the alternative explanation for the moon's phases is. In reality, you're just an ignorant fool who doesn't have a clue what they're talking about.

@@Memry-Man first you need to have the ability to think in 3D , looks like you lack that ability

A simple, physical model like this is often better than a fancy animation!

earth rotates 29x faster than the moon orbits earth.

@SpottedSharks yes that is fine. But imagine the lady with her back to the sun. Which angle would you hold the moon to get different phases.

@@hanselfernandes i suggest you do the demo for yourself

I agree, this demonstration has problems

@@GDGardner The demo is a very basic simulation of what causes the changing phases of the moon as observed throughout the month. Obviously, as the moon orbits the earth, we see the moon's changing orientation with regards to the sun and how this effects which parts of its surface are being illuminated and which parts of in shade. The demo has limitations, but it's not quite right to say it has 'problems'. Just out of interest, do you actually agree that the changing areas of light and shade on the moon's surface are as a result of the moon orbiting the earth and therefore its changing position relative to the sun and how we see these changes from earth?

Please tell me that you're actually mocking these deluded flat earthers with sarcasm, or are you actually being serious?

@sailorman8668 please tell me you don't believe the earth is round!

@@sailorman8668Ignore this sailor guy, he's stalking the comments section
