okay so check this out here we go now that we got these times now we can finally start talking about the moon phases okay and the reason I put these times in here is this the Sun always rises at sunrise and always sets at sunset it's always out during the day the sun's a daytime thing when is the moon out when is the moon out when is the moon out yeah some of you know that I'm trying to trick you with this question okay I'm trying to trick you trying to trick you because we typically think of the the the Sun is a daytime thing and the moon is a nighttime thing but the moon is out at a different time every day and it turns out that it's out during the daytime hours just as much as it is during the nighttime hours okay and the reason for that is if we were to look at this picture for a long time and of course it freezes up when I try to do something there we go in this picture we could imagine the Sun just hanging out up here for for the entire time and the earth hanging out here for the entire time but the moon remember orbits us okay and depending on where it is in the orbit it's going to be out at different times okay so for example when the moon is over here it's on the same side of the planet as the Sun is so it would be out during the day more than the night when the moon is over here when's it gonna be out when the moon is down here on the opposite side from the Sun when are these moons gonna mainly be out they're gonna be out mainly in the night right so basically because the moon is orbiting around us the time that it rises changes every single day and here's the next question does anybody know how long it takes the moon to orbit around the Earth how long does it take the moon to orbit around the Earth roughly I don't need an exact yeah so it's about 28 days okay it's about 28 days it's not exactly 28 days it's about four weeks okay it's an easy way to think of it is it's about four weeks or in other words okay here we go it's about a month right give or take it's a little bit less than a modern month but it's about a month right and that's not a coincidence check it out the word month is month okay a month is a move that's where the word month comes from months were originally set up to be moons but we're just saying it wrong now right so and we've tweaked the calendar since we originally set up when a month was and that's why it no longer actually matches the month but that's where that word comes from okay so a it takes roughly a moons okay now but let easier for us though just think four weeks okay now because it takes four weeks that means that as the moon slowly moves around the earth it's gonna rise roughly 50 minutes later every day every day the moon rises about 15 minutes later than the time before oh and by the way I want to make sure you understand what I'm showing you here this is not the moon going across the sky every day this is us view from space of the moon slowly taking four weeks to go around okay now with that in mind here we go we're not quite to the phases yet but we're getting there check this out here we go now the reason I told you to draw the the times on here is that now we can figure out using this figure what time every moon is going to rise okay every because the moon moves through its orbit every phase is gonna have a different time that it rises okay and I'm just gonna start with let's start with Moon a okay let's start with Moon a let's not worry what its gonna look like let's just try to figure out when is it gonna rise when is it gonna set and when is it at your Zenith okay so here's what you're gonna want to do take your figure whichever moon you're trying to figure out turn that page so that the one you're figuring out is at the top okay so you want to be able to spin around the earth like this but spin it since we're trying to figure out moon a figure it put moon a at the top of the page okay now check it out would you be able to see this moon right here this moon at midnight would you be able to see that moon at midnight yes or no no no you can't because if you're standing here you're standing on the opposite side of the earth of this moon okay if you're standing at the midnight time the midnight place on earth the earth is totally in the way of that moon right if you want to see that moon you're gonna have to wait okay all right and if I'm spinning around the earth the first time the earth would not be blocking my view would be at 6:00 a.m. because now if I'm standing here nothing is blocking my view so you know there's nothing between here and here I can see moon for the very first time at 6:00 a.m. okay I can see that moon for the very first time at 6:00 a.m. and if I'm seeing it for the very first time what does that mean that moon is doing at 6:00 a.m. what is this moon doing at 6:00 a.m. if I'm seeing it for the first time that day what's it doing you're seeing it for the very first time and give you guys a chance to a guess it's rising okay it's rising that moon when the when you're spinning around the earth once you've spun so that the earth is out of the way if there was a person standing here their feet would be on the earth their head would be up here they'd be looking to the side to see that moon okay so that moon would be rising because it's the first time that the earth got out of the way and gave you a view of it so that means that moon rises at 6:00 a.m. now I'm showing you the complicated background of this right now in a second I'm gonna show you a very easy way to figure all of this out okay so moon a here rises at 6:00 a.m. can anybody figure out what time it would be when this moon is directly over your head see if you guys can figure that out Winwood Winwood moon a be directly over your head when would it be at your zennith at noon if you were standing here at noon you'd look straight up to see this moon so that means this moon is at your zenith at noon okay so the time pointing at it is the time it's straight over your head so it rose at 6:00 a.m. it's gonna be right over your head at noon if it rose at 6:00 a.m. it's gonna be right over your head at noon now somebody is saying but like isn't it blacked out I'm not talking about how it looks right here I'm talking about where it would be in the sky okay don't worry about what it looks like but it would be above you at noon okay I'll get to how it looks in a second and then can you tell what's going to happen at 6:00 if you keep spinning around the earth when it turns 6 p.m. a second after that you move behind the earth again you move back underneath the earth and that means you can't see that moon anymore after 6 p.m. so what does that mean uh is happening at 6 p.m. it's setting okay it's setting somebody's saying that the the stream is going a little wonky everything's still good on the stream guys things still working out just making a sure okay good okay all right so again let me just go through it one more time if we're looking at moon a at midnight I can't see it because the Earth's in the way 6:00 a.m. is the first time I can see it because I spun out from underneath the earth so it rises at 6:00 a.m. it's straight above my head at noon and it sets at 6 p.m. because if I spin any more I'll be behind the earth again okay now check it out check it out here we go let's do a different moon let's do moon see if we put moon see at the top okay if we put moon see at the top we can figure out the same thing again in the exact same way okay check this out on this moon if the moon is here because it's not in the same place as it was before all the times change if if the moon is here I can't see it at 6 a.m. because if I'm at 6 a.m. now the Earth's in the way okay if I'm now I'm on the opposite side of the earth as that moon ok so what would be the first time I could see this moon if I'm spinning around the earth when I get here now I can see the moon again okay when I get right here I can see the moon again so what time does this moon rise what time does moon see rise at noon right noon is the first time I can see that moon so that one's gonna rise exact when we're having that phase the moon will rise at noon okay what time is this moon gonna be straight over your head well if this moon is straight over your head then you're standing here right because if you're standing here you'd look up to see that moon so that means the zenith time or the straight up time for this moon is 6:00 p.m. and then finally we want to figure out when is it going to set when is this moon right here going to set well if you keep spinning the last time you'd be able to see it is at midnight right so that means this moon rose at noon and set at midnight so that moon would be up half during the day and half during the night okay now check this out here we go I want to go back just check this out when we were doing moon a it rose at this time the time that was on the right and it's set at the time that was on the left okay when we just did moon see it rose at the time on the right and it's set at the time on the left okay let's see if we can figure this out if we do moon II if we follow the pattern what time should moon II rise what time should moon II rise 6:00 p.m. the time on the right that makes sense because if you were standing at noon you can't see that moon if you wait till it spins here then the time on the right is when you get out of the way of the earth okay so yeah what we can do is if we put these times in the right place on the figure and we put whatever moon we're trying to figure out at the top then whatever time is to the right is the time that that moon will rise and whichever time is to the left is the time that that moon will set okay so this moon right here rises at 6 p.m. sets at 6 a.m. this moon rises at noon sets at midnight this moon rises at 6 a.m. sets at 6 p.m. so if you set up your figure right you don't have to memorize 8 start and rise and set times for every single moon because all you got to remember is right Rhys left set okay right right I'm gonna put myself in the middle here oh wait but Papa dude uh here we go right Rhys left set right Rhys left set and here's how I remember it right Rhys right right right right right right right rise right Rhys right right Rhys right Rhys left set whatever just remember right Rhys left is the other one now now and the time that points up at the moon whatever moon is a what time points to it is your Zenith time okay now here we go by the way when I do that in class I have like a whole a whole dance for right Rhys left set and I do it and everybody just cringes at it real hard and then everybody remembers it so yeah now some people have pointed it out a little bit of a tricky part and that's you know what about like this moon or this moon or or this moon or this moon I can't do I don't my green screens right here I literally don't have dancing room unfortunately so I can't do the dance I'm sorry I'm sure if you search snapchat enough somebody has me dancing on there so you know look around you'll find it now oh and don't worry the dance is not good so don't worry about anyway let's get through this what do we do about like moon B everybody turn moon B to the top so that this figure is now kind of diagonal okay I got it diagonal the Sun lights coming in from up here what do we do about this one well here's the thing okay we said that it takes 20 eight days for the moon to go all the way around the earth right twenty-eight days to go all the way around the earth but there's not twenty-eight phases okay there's not twenty-eight phases okay we said it takes four weeks for the moon to go all the way around four weeks to go all the way around so don't overthink this here we go if you go from A to C how long would it take the moon to do that if it takes four weeks to go all the way around how long does it take the moon to go from A to C now it froze up on me yeah one week right if it takes four weeks to go all the way around it's gonna take one week to go that first fourth another week another week another week now the moons that we kept talking about a second ago the ones that line up perfectly with times those fours phases so a c e and g those phases only happen for one day okay they only happen for one day of the entire cycle those are one-day moons right there a c e and g and again you can tell if it's a one day moon if it lines up perfectly with a time now if they're all one day moons can moon b be a one day moon can moon be how many days does moon b take how many as the moon goes through here how many 10 we said it takes a week to go from A to C so how many days is it gonna be a moon B six same thing with mundi it takes six days here so moon phase moon phase B the moon's not always right here what it's doing is it's moving after moon a it's here and then here and then here for six days I just drew one of them so what that means is someone saying that they're glad they took their math classes good job six plus one is seven yes very very good on that knife but what I'm saying here is this the moon's that don't line up perfectly with a time we can't give an exact time because there's gonna be six different times that that moon rises but we're not going to memorize all six one of those times essentially what you could do is take the time that moon a rose and add 50 minutes a bunch of times to get all the times but here's what we can do we can still do write rise left set okay we could still do it but for the ones that are on the diag instead of giving an exact time you're just gonna say a time between this and this so let me show you what I mean if we're doing moon be right rise would be right here right right rise would be right here so I could say moon be rises between 6:00 a.m. and noon that's all I would have to say so if I asked you when does Moon be Rise on a test what I would want to hear is between 6:00 a.m. and noon that's still to the right okay okay let's do left set for this moon left set would be over here so when does Moon be set if we're using left set when does moon be set give me in the discord when does moon be set it should be between [Music] something in something so if we're doing left set from this point of view left would be like over here and that's between 6:00 p.m. and midnight okay between 6:00 p.m. and midnight moon B would be straight over your head between noon and 6:00 p.m. so right Rhys left set straight up will be moon B now I'll go ahead and tell you the vast majority of the ones that I would ask you are gonna be the ones where you can give an exact time but I might ask for one of the between errs as well just remember right Rhys left set up zenith and you are good last thing I'm gonna say about that before we actually start drawing these moons how do we know we put the x in the right place because if you don't put the x in the right place you're gonna get everything wrong here's what I always remember wherever the sunlight points is new okay wherever the sunlight is pointing in is noon okay so once you found noon the other times just go in order so as long as you've got noon pointing to the Sun you've got those times in the right place okay
