Emily Morgan, author of Next Time You See the Moon, takes you through the phases of the Moon in a demonstration that will be easy to replicate in your own classroom. www.nsta.org/store/product_det... www.nsta.org/nexttime-moon
Lol I’m 27 and exact reason 😂😂 I remember learning this in my astronomy class my freshman year of college but since then it has completely left my head😂
lmaoooooo same xD also my friend's little brother showed me this video and was shook that there was other phases of the moon besides crescent and full.
I am 63 years old and now finally understand the moon phases. Was sitting outside tonite and saw a crescent moon. Trying to figure out the reason behind it. You explained it so easy. Thank you!
I am here for exact same reason. Yesterday I saw crescent 🌘 moon. And today is new moon, so kinda curious. Bty the 2nd crescent 🌘 moon is so fascinating than the 1st 🌙 moon. Because in 2nd crescent 🌘 moon you can see the darker part clearly.
Nice! You are never too young to learn! Now try to imagine the motion of the earth around the sun and the way you see the sky at night. It took me years to get my head around that. It still boggles my mind how this works, I could not figure out why and how Polaris (the North star) could stay in the north.
Have any of you noticed that the crescent moon used to be crescent from top to bottom and now it is more side to side??? So, if you didn’t understand what I am saying try this… crescent moon used to be a “(” or “)” now it is more of a ”u” shape and an “n” shape, so instead of it being top to bottom it is now more side to side. Has anyone else noticed this or am I just crazy???
I've watched several videos about this and this was by far the best visualization I've seen, so much better than the computer animated ones everyone else uses.
It's easier to show this way because she isn't taking in all of the variables. Out of honesty, the programer has to deal with most of the major motions. This also brings up complicated questions...
@@MH-53E What 'complicated questions' are you referring to ? You could have asked one, at least. But that would mea you would have to KNOW what to ask. Right?
Ok I’m 59yrs old and have long forgotten being taught that in school. I came on RU-vid and watched a couple videos, but your video explained it perfectly! So thank you for sharing and enlightening this ole girl! 👍🏽
What she was doing is not at all serious! She had not spinning the Earth [represented by her head] around the Sun !! In fact, nobody in the world has been able to explain correctly what the Moon actually does, in relation to the Sun !!! I regret to write it to you, but her simplistic explanations are not even good for teenagers ..... professor essef, in mathematics (active for over a year, on RU-vid and Wikipedia, in astronomy & astrophysics). Greetings from Paris.
Her demo makes you have eyes the size of the earth. When her own computer model shows how everyone will see a full moon every day, as the earth is spinning towards the lit par of the moon, when it's only half illuminated - @3:22 - look at that model of earth and think about the peoples' view on those spinning continents.
Up until watching this video, did you actually have no idea as to what causes the changing phases of the moon? Perhaps you've yet to learn what causes the seasons too?
Sailorman, don’t be rude. There is plenty of “simple” things each person doesn’t know, no matter the age. Doesn’t mean you arent intelligent. It just mean you don’t know
@@shaspearman8647 If a 45 year old still doesn't know what causes the changing phases of the moon, it isn't a matter of 'don't know', but a profound ignorance of basic facts that any adult should know.
This is guaranteed misinformation so why when building up to the full moon it goes the way that yea you could make that argument it’s reflecting sunlight but when it winds down it’s makes absolutely zero sense the moon is it’s own light source not to mention nobody ever ever landed on it I’ve been studying the moon for three years and I can for sure tell you this is not how it gets it’s light
thank u so much, this as fantastic!! if my teachers were as creative as u, I wouldn't have to be searching this video at 22 yrs old just to really confirm my understanding! (& i'm a uni graduate...)
+Tila Wilderman I apparently didn't learn left from right, because I'm here because I didn't understand why 3rd quarter and 1st quarter didn't look the same with light on the same side. D'oh!
I have watched endless videos on phases of the moon trying to get an understanding. This is the first video I’ve watched and got a full understanding ❤
The moon orbits the earth once every 4 weeks or so, which means we see different parts of the moon's surface being illuminated by the sun - this isn't rocket science to understand.
I'm like doing BSc final year, finally at age of 20 I understood how phases of moon are formed. Can't thank you enough!!! Such a simple and great explanation
1:22 I can’t understand isn’t that lunar eclipse and also their is day on the earth so how is new moon on night ? 3:22 And here also there is day on earh so how is there new moon on night ?? Please can you explain?
Why suddenly this looks so awesome and miraculous? I’ve always known this but it just this realization that this planet we are living on is spinning and this moon is perfectly spinning around it and the sun is doing its thing...this whole creation is just cool.
This is what all the RU-vid videos should be easy ,simplified so everyone will be educated & successful in their life. Btw I'm 22 and forgot how moon works so had to see this
Satanic brainwash aka education. The earth isn't a silly ball so dumb how nobody thinks for them shelves anymore just trust these satanists with their made up garbage. The moon doesn't rotate like this idiot said it does. If the moon was a ball you'd see the other side of it but we don't. Look at it at moon rise and moon set, it tilts/spins like a steering wheel and not like a ball. Flat earth proofs... Check out these RU-vid channels... A potters clay, DITRH, Eric Dubay, A plane truth 5, hundreds of good truther channels out there. Can't argue with facts and 100% agrees with the Bible and is a proven fact we're not on a globe. This is Satan's world, I know you dumb brainwashed children were taught there is no God no devil no heaven or hell but there is, heaven above hell below. You are trapped IN the earth, nobody gets out alive.
Are you actually saying that up until watching this video, you had no idea what caused the changing areas of light and shade on the moon's surface throughout the month?
@@C_Becker In the same way running a car on water is impossible, yet Stan Meyer did it in the 90s and suddenly died of food poisoning in a restaurant and his patents disappeared. Or the Tulsa Massacre that was erased from history. Or we killed 70 million native americans by getting them sick from our viruses... Sure okay.. Keep believing those in power. If space was real, billionaires would've had hotels on the moon just to be the first. Space is actually water, All the holy books are telling the truth.
I'm not so sure about that. I've seen many comments posted here that make it obvious that people still think it's the earth's shadow that causes the shaded area on the moon's surface, despite having watched the video.
It took me 38 years to realize this. 12/22/2021, @ 06:37 p.m. marks the first-time-ever I fully realized how the moon really works based on your demonstration. Thanks to my buddy who didn't come to pick me up for tonight's party, making me have time to check this out😂✨
the moon has been observed in the same day sky in a observers vison and not to look away but both celestials are in ones vison so for this Reason its incorrect!
@@couchninja2997????? That is perfectly shown in this demonstration. You can have both bodies within your field of vision, it just affects how you see them. However, you can ALSO have them opposite of each other from the observer's point of view.
Are you being serious? You've been alive for 39 years and you've only just found out from watching this video what causes the changing phases of the moon? I'm assuming you're completely clueless as to what causes the seasons too?
When she places the white ball between her head and the light , she says it is no moon day as there is no light on the moon. And then the crescent moon appears. But this time earth is facing the sun which means day time in the earth. What about the the darker side of the earth which normally witnesses moon ? We only see crescent moon during the night and not during the day time. Something is wrong in this explanation .
It's not wrong, but rather simplistic. - "she says it is no moon day as there is no light on the moon" That's called a New Moon, yes. A little correction there though, the Moon is illuminated during a New Moon but on the far side. The side facing us is not receiving any sunlight. - "And then the crescent moon appears. But this time earth is facing the sun which means day time in the earth." Yes, and? - "What about the the darker side of the earth which normally witnesses moon" Therefore, at this particular phase they don't see the Moon. You can see the Moon during the night when it's still crescent and almost half-full. When it's very recent (when it looks very dim and kind of like a recently cut nail) it will set an hour or so after sunset. - ''We only see crescent moon during the night and not during the day time'' Wrong. We can see the crescent Moon when it's almost half-full during the day, but not when it's very recent.
@@oscarin13 yeah your so good ,is your head is still spining , but the shit still sticks to it ,mey be becouse you are a shit head,ha ha ha , idiot the moon its got its own course notting to do with the sun,,and by the way your explanation is not working with a spining globe ,children whom refuses to grow up
Rajkumar is bang on. The crescent new moon only appears when the sun is setting & only for about 10 minutes. But sometimes it doesn't appear bc it's below the horizon & appears the next day. The video is incorrect
And yet, this particular video makes no mention of why there isn't a solar or lunar eclipse every month. That's quite a glaring omission, which many other videos do actually address.
Now that I'm shadow-banned for the crime of being conservative, I just wanted to post a quick reminder that this is the BEST vid for schoolkids on this topic I've ever seen. Retired Science teacher here, and I hope someone sees this before it's taken down.
Even though this video is aimed at 'schoolkids', there will be some 'smart' students who will ask why there isn't a solar and lunar eclipse every month, but the explanation for this is not contained in this video.
at 1:46 we call that crescent a waxing crescent at 2:04 we call that a waxing gibbous at 2:21 we call that a waning gibbous at 2:39 we call that a waning crescent which means that new moon is a couple of days away
@Ada Ghost Perhaps you should create one and upload it to your channel and come back here with the URL so we can judge yours against this one. Looking forward to yours!
Thank you for this quick and easy video demonstration. I will show it to my class tomorrow for foreign language students who need the extra visual. "A picture really is worth a 1000 words," and a video is worth even more. :)
There are good explanations on YT on how and possibly why the moon is tidal locked. Since it's a physical phenomena a visual explanation is more clear than just explanation.
Thank you. I always forget the names of the moon phases and love to see it compared to earth and sun. Many videos either just show the earth/moon or earth/sun but not all 3. Your explanation makes it easy to understand. Thank you!
Great, best way of explaining with the demonstration, many people have some confusion after having news or information bt. your demonstration makes clear enough.
Thank you so much Ms. Morgan! Your video was just fantastic, and that’s because your demonstration is extremely close to what happens in real, and that it allows us to see it action.
Actually I am 49 still can't understand how does the moon sees round in shape from our planet Earth and sometime my children asked me but throught your channel I now understand what exactly does moon work, thanks you so much ma'am.Lots of love and care from my family, Imphal Manipur 🇮🇳. North East India.
The moon phases move right to left in the northern hemisphere, if you’re in the southern hemisphere, waxing moons are lit on left and waning moons are lit on the right
Hey, Benjamin Middleton, thanks for the great vid! One small error - when the moon is directly between your head (the earth) and the sun it is an eclipse.
Yes, you are correct. However, the Moon's orbit is tilted slightly, which doesn't allow this to happen every month. She doesn't cover this detail in this video. I do a similar activity with my students and then we add this to the discussion and begin talking about eclipses and why don't see them every month. I think for the purpose of the video, it would be difficult to show a new moon without blocking the light because the light would create quite a glare on the camera making it difficult to see what is happening on the Moon. But, I understand your point.
@@SWIGDOG913You can take long exposure photographs of the eclipse, and see the (dimly lit by the earth) near side of the moon. You can watch it move it towards the sun in the days before the eclipse and away from it after. Claiming that the moon doesn't cause eclipses is delusional
In this demo, Emily hold the moon model above her head throughout her explanation. So, she is demonstrating that the moon must either revolve in some plane but either above or below the obstruction of the earth, otherwise the earth would totally eclipse the moon every revolution. This would mean most everyone on the side of the earth not facing the sun, won't be able to see the moon because of the shadow cast over the moon by the earth. It's like as if there are two 'new moons' for each revolution around the earth instead of one 'new moon'. This demo is not the complete story of what's going on. I'm still in the dark, so, can someone politely explain the anomaly I observed while watching Emily Morgan's otherwise flawed or half explanation please? Someone from the National Science Teachers Association or Emily herself preferably.
She holds the moon above here head because the point is to show what CAUSES the phases of the moon. That point is sufficiently addressed. Your question is outside the scope of this demonstration, but it can be explained. First of all, understand that the scales involved are WAY off in this demonstration. The Earth and moon a lot farther apart and the Earth and sun are a lot farther apart in reality. Because of this, the position of the Earth-moon-sun system needs to be pretty perfect for the moon to cast a shadow on the Earth or the Earth to cast a shadow on the moon. In reality, the moon's orbit around the Earth is inclined by about 5 degrees relative to the plane that the Earth orbits in around the sun, so for the moon to actually cast a shadow on the Earth (solar eclipse - during a new moon) or for the Earth to cast a shadow on the moon (lunar eclipse - during a full moon), the moon would have to be reaching the point where its orbital plane around the Earth crosses the Earth's orbital plane around the sun at the same moment as the new moon or full moon occurs respectively. This actually happens relatively rarely, but it's not THAT rare. - otherwise eclipses would be rare, and we get a few per year - just not every month. Here are some basic things to know about the orbit of the moon : There are two ways we define the moon's orbit around the Earth. The first is the time it takes for the moon to orbit the Earth relative to distant stars. This happens about every 27.3 days, and is called the sidereal month. If the moon is crossing the ascending node of its orbit and the Earth's orbit around the sun - that is at the point where it's orbital plane intersects with the Earth's orbital plane - and the moon is coming "up" through the Earth's orbital plane (ascending), then the next time it will approach that point in its orbit is about 27.3 days. The second way we define the moon's orbit around the sun (the one most people are familiar with) is the synodic month. This is how long it takes to make one revolution around the Earth relative to the Earth and sun system. That is - how often do full moons repeat, new moons repeat, and so on. This is about 29.5 days. The reason they are different is because the Earth orbits the sun. In the moon's sidereal month - that is when its in the same position in its orbit with respect to space (stars), the Earth has actually moved around the sun some - so the moon has a little bit farther to go (and takes about two and a half days to do it) to get into the same relative position. So, now imagine you are watching a solar eclipse. The moon has passed directly in front of the sun at the moment it is crossing the ascending node in orbit. The phase the moon is currently in is the new moon phase. This phases will not happen again for 29.5 days, but the next time the moon will be crossing the ascending node will be 27.3 days, so on the next new moon, the moon will have already crossed and moved above the orbital plane of the Earth and will be 2.5 days "ahead" so to speak. On the next new moon, the moon will have intersected the Earth's orbital plane 5 days prior, and so on. Eventually, they will line up again, and the moon will intersect with the plane of the Earth at the moment of a new moon or full moon, and give us another eclipse. There are only two points in its orbit where the moon will be intersecting with the Earth's orbital plane - once when it intersects it moving upward (ascending node) and another point where it crosses the plane moving downward (descending node). We will only get an eclipse when the moon is at one of these nodes during a new or full moon. Since the frequency of new and full moons does not sync with the frequency with which the moon will cross one of these nodes, the frequency in which they happen at the same time is simply low.
I would suggest you go with all honesty and consider flatearth model!! You will completely be enlightened as for someone like you seeking an explanation... best of luck!!
M Ameen Yes, I am tending 'two-dimensionally' at the moment. NASA is a pack of thieving, lying, fascists that I can't seem to put my faith in. Yet, in these times 'the majority' don't seem to mind thieving, lying anything. Truth is the dirty word, or so I've noticed. But how UN politically correct of me.
Thank you so much! This is such a beautiful demonstration, thank you💖 I'm 21 and have just realized how the orbit of the moon actually works, I'm not proud but better now than never.
the moon has been observed in the same day sky in a observers vison and not to look away but both celestials are in ones vison so for this Reason its incorrect!
...it's too bad the nuns and priests in my catholic school upbringing couldn't explain it like this! "because that's how God made it" just doesn't cut it!
@@sailorman8668 Like many people here, wasn't 100% sure if the phases of the moon were from the sun shining on it at an angle, or the sun casting the earth's shadow on it.
@@jskay77 Oh dear, so you actually thought that the changing phases of the moon were possibly due to the earth's shadow being cast on the moon's surface? Have you never heard of a 'lunar eclipse' and what causes it?
@@sailorman8668 I know. How unfortunate that I couldn't have been born an omniscient youtube troll leaving condescending comments that feed on the bewilderment or lack-of-knowledge of others. Much like why crumpled-up oily rags can spontaneously combust when the oils react with ambient oxygen to form peroxides and hydroperoxides and polymerize into an exothermic polyaddition reaction to the point of autoignition, I - like many others - simply did not give a $hit to investigate further until recently.
