3rd Grade Science Compilation

Wow we are gonna learn so many cool things on this home school pop video all right what's the first thing we should learn how about earthquakes and the first thing we need to understand is the earth has an outer shell isn't that interesting this outer shell is called the crust crust you know like like bread crust and I hope you enjoy bread crust by the way because you can't eat the crust of the earth but I hope that you're eating the bread crust you know it's still yummy it's on the outside fact it's really healthy it's really great okay let's get back to the crust of the earth you know you don't eat the Earth's crust but hopefully you eat this kind of crust okay the surface of the earth is part of this outer shell remember the outer shell is called the crust this means that hills mountains and valleys are all part of the Earth's crust that means even the floor of the ocean is part of the Earth's crust so what is the outer shell of the earth yeah the crust and you know it's fascinating the crust has lots of pieces and is almost like a jigsaw puzzle and you might not realize this but these pieces of crust are always moving in fact they're moving right now the pieces of crust fetor below you right now are moving they're always moving now usually the crust moves slowly it doesn't move very fast when the crust moves slowly you don't feel it the pieces aren't moving beneath you but you don't even know because they're moving very very slowly you can't even feel it sometimes however the pieces of crust can move really fast they can move quickly when the pieces of crusts are moving quickly an earthquake can happen so when the pieces of crust moves slowly you don't feel it but when the pieces of crust move quickly you could have an earthquake earthquakes begin under Earth's surface and shake the ground here's a picture of something that can happen when there's an earthquake do you see the massive cracks in the ground this is from an earthquake the earthquake began under the Earth's surface as shook the ground and it caused this crack oh my goodness look at this picture that shows damage from an earthquake the earthquakes can also break down buildings bridges and roads they don't just cause cracks in the ground they break all kinds of things around us earthquakes are so powerful they can change Earth's surface well you may be wondering where do quakes start earthquakes start underground at a place called the focus you can see it here on the picture now that's a weird name for it I know it's called a focus we don't know why but that's just the way it is it's called the focus it's where the earthquake starts the earthquake is the strongest at the spa above the focus called the epicenter you can see from the picture it's directly above when an earthquake happens you don't want to be anywhere near the epicenter [Music] while earthquakes are very powerful they don't last that long in fact most earthquakes last less than a minute remember a minute is 60 seconds it's not too long and did you know this earthquake fact earthquakes get scored by how strong they are that's pretty neat earthquakes get their own score their own number scientists use seismographs to measure and score earthquakes the bigger the number the stronger the earthquake so here are some common earthquake scores a 1 or a 2 earthquake you barely feel it the 3 to 6 range of earthquakes they're gonna be some damage but 7 plus any number that's 7 or higher for an earthquake score that's a massive earthquake and there's going to be tons of damage remember the earth has an outer shell in this outer shell is called the crust the crust has lots of pieces and is almost like a jigsaw puzzle and all the pieces are always moving but if they move too fast that can cause an earthquake and an earthquake changes the Earth's surface and can damage roads bridges buildings and even crack up the earth and remember the earthquake is the strongest at the spot above the focus called the epicenter you don't want to be anywhere near the epicenter if an earthquake was to happen thanks for learning about earthquakes with us a powerful way that Earth's surface changes you're doing great you're increasing your skills just like this racer you're racing on the water you're increasing your skills you're doing a wonderful job and next we are going to learn about the first three help plants get water make food and row they are roots the second three help plants grow new plants they are flowers fruit and seeds so let's learn the plant parts one by one first the part that the plant get water make food and grow okay so the first plate part we're gonna look at today are the roots roots have a special job you see roots hold the plant in the soil the soil is the dirt in the ground then roots bring water and nutrients from the soil to the plant routes are usually underground but can be above-ground - have you ever seen a tree that looks like this where the roots are above ground remember the roots hold the plant to the soil okay so now we're gonna look at the second part of a plan which are the stems now the stems hold the plant up above ground the stems carry water and food through the plant stems are the delivery system of the plant roots get water in nutrients from the soil and the stems carry the water and nutrients throughout the plant remember the stem holds the plant above ground the next part of the plant we're going to learn today are leaves the leaves are on the end of the steps of plans and this is interesting leaves are where plants make most of their food we've take in air and they use air water and sunlight to make food remember leaves are on the end of the stems okay so next the parts that help the plant make new plants next part we're gonna look at our flowers flowers like leaves grow on the end of the stems flowers are often the most colorful part of the plant okay now this is awesome the rich colors of flowers help attract pollinators that's why they're beautiful the beauty has a purpose after getting pollinated flowers can make seeds and fruit do you love fruit the fruit is awesome you have flowers to thank for that flowers make fruit so the next time you're eating an amazing piece of fruit just think to yourself thank you flowers thank you flowers [Music] remember flowers are the colorful growths on the stems the next part of the plant we're gonna learn about is the fruit [Music] all right now we're on the plant is the fruit fruit hangs on the end of stems now you might be wondering what's the fruits job what does the fruit do well the fruits job is to hold the seeds the fruit is just a delicious seed holder now either one of two things happens to fruit fruit is either picked and eaten or it falls off the plant and rocks remember fruit is the tasty stuff on the stems [Music] okay the last part of the plant that we're gonna learn today are the seeds [Music] so where are the seeds of the plant seeds hide inside of the fruit now the seeds have an incredible job you see seeds grow into new plants okay you might be wondering well how does that work well here's one way when animals eat fruit they eat the seeds later the seeds leave the animal through its waste wherever the animal is this is called dispersal or fruit falls from the tree and rots the word rots means dies dies rots the seeds fall out and can make a new plant the first way called dispersal takes the seed to another place so it plants a new plant in a new place when a fruit falls and rots it plants a new plant nearby the original plant remember seeds live inside of the fruit Hey look like you're doing a good job pay attention about the arts and now we want to see how much work we're gonna play a game called named the plant part we're gonna show you a plant part and then you go ahead and tell us which plant part it is all right hope you're ready cause here we go look at this picture of a plan which plant part is colored in ha ha the fruit the fruit of this plant great job [Music] here's next one what clip part is colored in [Music] now the leaves the leaves are colored a great job [Music] all right it's time for this one it's colored brown which plant part is this [Music] ah huh the roots awesome okay let's try this one what part of the plant is colored in you see it there on the bottom what is that yeah what part is that yes the seeds let's try this one look at the picture could you name the play apart which plant part is that you can see it's outlined in color yeah the flowers awesome job oh this little baby's putting together a little craft you know oh it's so great I just love that that's house so good wait a second that that papers from that book isn't it okay this is see this is this is not an approved arts and crafts activity right now okay we're gonna have to take care of this but first let's learn about solids and liquids solid and liquid our states of matter matter is anything that takes up space now matter comes in different states or forms they're solid there's liquid and there's gaps today we are focusing on solids and liquids and how to classify them we're gonna start with solids matter is a solid when it has its own shape let's show you so here are some examples of solids remember matter is a solid when it has its own shape here is a coat a coat is an example of a solid it has its own shape it's an interesting shape it's the shape of a coat but it has its own shape it's a solid [Music] here's another one there's a laptop computer it's an example of a solid it has its own shape it has its own shape it's a solid piece of matters here's another solid a scooter an electric scooter that looks really awesome fun to ride him it's a solid right it has its own shape it's a solid oh I love making these a paper airplane is an example of a solid it is matter that has its own shape its solid matter is a solid when it has its own shape now let's learn about liquids matter is a liquid when it takes the shape of its container here are some examples of liquids our first is water and notice how we had to have it in a bottle in this picture because it doesn't have its own shape it takes the shape of its container because water is a liquid here's another liquid honey honey takes the shape of the container it's not solid it's liquid it takes the shape of its container doesn't have its own shape it's a liquid here's the last example of a liquid it's coffee and it's in this cup it's taking the shape of the cup because it's a liquid it doesn't have a shape matter is a liquid when it takes the shape it's all right so solids have their own shape and liquids take the shape of their community all right I think you're ready I think you're ready to handle this we're gonna play a quick game and figure out if these items are solid or liquid so I hope you'll help me out I hope you'll participate we need to figure this out [Music] our first one choose solid or liquid yeah juice is a liquid it takes the shape of its container how about this a cup is a cup solid or liquid yeah it's solid it has its own shape let's try milk is milk a liquid or solid yeah milk is a liquid it takes the shape of its container [Music] how about this one honey is honey a liquid or a solid yeah it's a liquid it takes the shape of its container let's try a car is a car a solid or a liquid it's a solid it has its own shape great job how about shampoo is shampoo a solid or a liquid huh Shampoo is a liquid it takes the shape of its container solids have their own shape liquids take the shape of their container okay that was pretty cool you seem to know a lot about solids and liquids now so the next time you're drinking something or you're holding something you can say yourself I know what this is here's our friend Fred we heard that he just took up the harp he just started playing the harp Fred we can't we can't hear you we're having audio problems with Fred right now Fred you look so happy playing we can't hear you okay you gotta you gotta where my curse up so we can't hear the music he doesn't even know isn't that nice you know fred is just plucking away he's having a good time you know like we're having a good time right now with these learning videos and next we are going to learn about the planets of the solar system now as we begin we have to answer this question what are planets a really good question what are planets planets are round objects that orbit the Sun here is a picture of the Sun it's the largest star in our solar system its massive and you can see there's a ring around those are some solar flares fire shooting out of the Sun absolutely amazing and stunning and it kind of looks like a pizza actually the word orbit means to circle around that means planets around objects that circle around the Sun what 3d shape is a planet think about it what 3d shape is a planet we know that a planet is round what 3d shape is perfectly round yeah a sphere yeah planets are spheres they're perfectly round a good job to summarize planets are spheres that go around the Sun pretty simple huh hey did you know there are two types of planets yeah it's really interesting there are two types of planets okay so there are primary planets and there are dwarf planets those are the two types of planets now there are eight primary planets these are the main planets that you think of the main planets that are circling around the Sun and these are the planets we're gonna be studying in this video and then there are five dwarf planets these planets are a lot smaller and are not considered primary planets sorry Pluto Wow there they are the primary planets you're gonna get to know all eight of these primary planets you're gonna know them so oh my goodness this is gonna be awesome the first planet is mercury mercury is the closest planet to the Sun the second planet is Venus pretty cool huh the second planet is Venus our planet earth is the third planet from the Sun the fourth planet is Mars Mars is the fourth planet the fifth planet is Jupiter that's the biggest planet of them all the sixth planet is Saturn and kind of love those rings Saturn is the sixth planet Uranus is the seventh planet and the eighth planet is Neptune Neptune is the furthest primary planet from the Sun let's look at each of the eight primary planets the first planet is mercury here's where mercury is it is the closest planet to the Sun okay the Sun is super duper hot so guess what mercury is a really really hot planet in fact mercury is four times hotter than boiling water have you ever seen boiling water it's so hot it's boiling it can cook things it's really really hot if you barely touch it you will hurt yourself so bad well mercury is four times hotter than that oh my goodness it is a very hot planet four times hotter than boiling water mercury is one of the rocky planets there are four rocky planets and Mercury is one of them oh and Mercury it is the smallest primary planet Mercury is so much smaller than the other planet I need a little baby mercury it's the smallest planet of the primary planet so if you think a small planet think of Mercury its small it's hot you wouldn't want to live there the next planet planet 2 is Venus Venus is right here it's the second planet from the Sun now this is interesting venus is called Earth's twin and the reason for that is they are very similar size they're almost the same size but what's interesting they're both rocky planets just like mercury is and Earth and Venus are made of similar rocks so there are pretty much the same size very similar size and they're made of the same stuff it's almost like the earth and the planet Venus are twins hey did you know every day on Venus is a cloudy day and the clouds are yellow it's such a gross color for clouds clouds are much better in their other colors then yellow so the sunlight doesn't actually hit the surface of Venus it's just a cloudy day every day forever but that's okay because there's no life on Venus so nobody's crying about it and this is cool venus is the closest planet to earth it is the easiest planet to see in the sky you don't even need a telescope how cool is that the third plan is hello ours the earth the earth is the third planet here is where the earth is yep it's the third planet from the Sun by the way these planets never line up like this we just have it like this so you can see the order of the planets but they're normally very very jumbled they don't line up like this just wanted to share that but the earth is the third planet from the Sun here's a picture of the ocean and some seagulls that are in some of the shallow parts of the water it's interesting earth is the only planet we know of that has oceans and life on it earth is one of the rocky planets we live on a massive rock that has oceans that has live I mean that's absolutely incredible remember four of the planets are rocky planets Earth has one moon the moon orbits the earth like the Earth orbits the Sun Wow there's our planet that's where we live the earth the fourth planet is Mars Mars is right here in between Earth and Jupiter the color is Mars look at Mars what color is that yeah it's kind of like a reddish orange because of its color Mars is called the Red Planet so if anyone asks you what's the Red Planet tell them hey the red planet is Mars even though it is red it is not hot it is much colder than Earth because remember Mars is further from the Sun than the earth so Mars it's red it almost looks like it would be hot but it's cold hey is there life on Mars it's a really good question that a lot of scientists have been trying to answer for a long time well scientists believe there used to be water on Mars if there was water there may have been life an even stranger there are some scientists that believe we may still find basic forms of life still living on Mars Mars is the fourth planet remember we said there are only four rocky planets so it's the last of the rocky planets Mars has volcanoes and valleys just like Earth they're just sometimes much bigger fact there's a volcano on Mars that's as big as the state of Texas Wow huge and this is kinda cool Mars has two moons they are both very small okay there's small moons which is good you know Mars has a couple moons it's nice we've got a moon Mars has two moons yeah Mars is the fourth planet from the Sun and it's in between the Earth and Jupiter the fifth planet is Jupiter Jupiter the first of the gasp planets here is where Jupiter is it's the massive planet between Mars and Saturn I mean Jupiter is huge it's the biggest planet in our solar system in fact all of the other planets could fit in Jupiter and there would be extra room all of the other planets could fit inside of Jupiter that's how big Jupiter is and this is amazing Jupiter has at least 63 moons and we say at least because they're still discovering more Wow and because Jupiter is a gas planet if you ever visited it you would just fall right through just kidding you would flow I mean they wouldn't fall the gravity wouldn't be there you just kind of float around yeah jupiter is the giant gas planet in between mars and saturn the sixth planet is Saturn another gas planet here is Saturn the sixth planet from the Sun you could spot it easily because of those huge rings and it's in between Jupiter and Uranus hey did you know Saturn's rings are made of ice oh my goodness okay whoo-hoo I see rings those rings are made of ice Wow like Jupiter Saturn has a lot of moons Saturn has 62 moons what's up with Jupiter and Saturn right and this is pretty awesome Saturn is the farthest planet you can see without a telescope that's right you can see Saturn with your own eyes without a telescope she shattered with my own shadow and I should know everything Saturn is a gas planet that's the sixth planet from the Sun and is in between Jupiter and Uranus the seventh planet is Uranus another gas planet Uranus is the seventh planet from the Sun and is in between Saturn and Neptune both Uranus and Neptune are the only planets you can't see without a telescope so it took a while for them to be discovered now this is me William Herschel discovered Uranus in 1781 it took us a long time to finally find the planet Uranus Uranus is a gas planet that is made of gas and liquid what's cool is Uranus has rings just like saturn has rings yeah scientists believe the rings of Uranus couldn't be pieces of broken moons we don't know for sure but that's really fascinating if that's the case speaking of moons Uranus has 27 moons 27 moons I think we just have 127 Uranus is the seventh planet from the Sun and is in between Saturn and Neptune the eighth and final planet is Neptune hey that means the first four planets are rocky planets and the last four planets are gas planets so here is where Neptune is it's the furthest planet from the Sun like Uranus Neptune is a gas planet that is also made of liquid Neptune was discovered in 1846 when Uranus was being studied they're like wait a second there's a whole other planet here on the end let's call it a net pen Neptune is known for its storms the worst storms in the solar system in fact winds reach over 1,000 miles per hour on Neptune whoa that's pretty intense Neptune has 14 known moons but scientists believe there may be more here's Neptune the furthest planet from the Sun you have done such an amazing job with us today today we learned planets are round objects that orbit the Sun the word orbit means to circle around basically the planets around objects that go around the Sun we learn there are two types of planets primary planets and there eight primary planets and dwarf planets there are five dwarf planets and here are all eight primary planets they're familiar friends now Mercury Venus Earth Mars Jupiter Saturn Uranus and Neptune the first four planets are rocky planets Mercury Venus Earth and Mars are rocky planets the four planets furthest from the Sun are the gas planets Jupiter Saturn Uranus and Neptune are gas planets hey when is it going to be my turn I want to be in this compilation video - okay let's see I'm going to teach about pollination hi look at all these beautiful flowers that I've found let's look at some more these flowers are so pretty look at how blue purple it's so beautiful I love these flowers but all the pollen is making me me and sniffily so I think we should go back inside all right that's better well flowers they make pollen and pollen is a fine powder it's usually yellow and it can make you sneeze just like me earlier flowers use pollen to make seeds through a process called pollination okay do you see these yellow feathery parts of the flower this is the male part of the flower called this Damon and that is where the pollen is Mary now this middle pink part of the flower is called the pistil which is the female part of the flower this is where the pollen needs to go so the flower can make seeds looking at this flower do you think the yellow parts are the stamen or the pistil that's right that's the stamen the stamen is the male part of the flower that's the part that makes pollen now here's a different flower do you think this purple part in the middle is the stamen or the pistil [Music] very good that's the pistol the pistol is the female part of the flower where the pollen needs to go so that the flower can make seeds when pollen is moved from the stamen to the pistol it is called pollination there are flowers that have both a stamen and a pistol but there are some flowers that have only a pistol and there are other flowers that have only a stamen pollen can't move by itself so how will it get to the pistol with the help of pollinators do you recognize this well-known pollinator very good that's a honey bee honey bees are pollinators and you can see the yellowy orange pollen on his leg right here pollinators are pollen helpers by moving the pollen to the pistol so the flower can make seeds let's look at some other pollinators do you know what this pollinator is called that's right this is a butterfly and this one is called a Painted Lady butterfly butterflies are pollinators what kind of animal is this that's right that's a bat this is a flying box which is a fruit bat and fruit bats are pollinators - what's this little guy called great job this is a hummingbird it's a ruby-throated hummingbird and hummingbirds are also pollinators other pollinators include wasps and Maude's ants and beetles like this ladybug are pollinators to these other pollinators are very well known they are bumblebees and honey bees all right let's review what we've learned today what is the fine yellow powder on this be called that's right it's pollen pollen is a fine yellow powder this yellow part of the flower makes pollen do you remember what it's called that's right that's the stamen the stamen is the male part of the flower that's the part that makes pollen why do flowers use pollen great job of flowers use pollen to make seeds this purple part of the flower is where the pollen needs to go so the flower can make seeds do you remember what it's called very good that's the pistol the pistol is the female part of the flower where the pollen needs to go so that the flower to make see what is the process called when pollen is moved from the stamen to the pistol great job when pollen is moved from the stamen to the pistol it is called pollination what is the name of the pollen helpers who move the pollen so the flower can make seeds that's right they're called pollinators pollinators are pollen helpers by moving the pollen to the pistol so the flower can make seeds now you know how the flowers around you make more flowers pollinators help them through a process called pollination so they can make seeds Wow you completed the video that is so impressive well you might notice there's a circle right here on this video page that you can click to subscribe to our channel or you can click this rectangle to go
