2 E 8 SCIENCE GRADE 2 UNIT 2 REVIEW MAY 17 2021

good morning everyone hope you all had lovely lovely weekend and you got to sleep in and you got to play hope you guys had fun with your science homework hop over to here first have already given everybody who did their homework one point on class dojo so you guys can take look at your points right now if you did your science homework you have one more point already so thank you everybody who did your homework okay already put it in here well let's get started everyone who did their homework has point on class dojo now okay let's begin science with miss miranda here we have our gas that fills its container liquid that takes the shape of its container and our solid puppy puppy can you read that today we will where we will reveal silent liquid gas volume and match excellent next one so first we'll do little review next how about jack can you read number two here's your whole video very good so after that we'll share homework videos and number three number three let's hear it from bunny starting with today can you read number three today we will use things in your house to talk about properties excellent very good nice reading bunny okay so the first part was the review remember we took look at this yesterday and now that you've done your homework maybe it'll be bit easier how many milliliters is this water on the left moon 17 17 what millimeter milliliters very good okay how many milliliters of liquid and solid together are on the right how many milliliters are over here on the right taylor there are 17 milliliters and the gold is three more and then it is 20 million excellent so exactly that means that this gold here must be three milliliters it added three milliliters of volume very nice taylor so that's how we can find out the volume of solid all right everyone let's see if we can do this as class number one everyone read number one who thinks they can tell us the correct answer who thinks they know let's start with zuke go ahead zoo with number one everything that takes up space and hash mass is called metal excellent perfect okay number two number two raise your hand using that button on zoom sofia go ahead the amount of maca in something is called math nice excellent work okay the amount of matter is mass number three number three rey go ahead with number three tomatoes cannot always be seen it's fresh can feel the face it is and it's as is called guy excellent work ray nice job okay next one let's have hands up raise your hand using zoom if you know go ahead susu that has shape of its own is called solid excellent it's very good all right number five pasta number five matter that flows and tastes the shape of your container it is liquid very nice okay and the last one who knows the last one let's hear from taylor the bottle on the right can hold larger volume of water than the bottle on the left excellent very good remember volumes how much space it takes up so we can put larger volume of liquid on the right okay solids read just the underlined words okay everyone read just the underlined words so there's four one two three four four things that are underlined let's just read those okay all right everybody go ahead and unmute and read solids very good and what does fixture what does fixed mean you can tell me what fixed means banana do you remember fixed what fixed means anyone else sam what does fixed mean stay the same stay the same exactly if move solid it still stays the same mass so it still has the same amount of matter and it stays the same volume it still takes up the same amount of space so it's fixed it stays the same everyone go ahead and say that fixed stays the same very good solids keep their own shape unless it's broken cooked twisted they have fixed volume so you can measure it using water and measuring cup just like our piece of gold and they have fixed mass you can measure it using scale or compare one minute to another object using balance so we measure using scale or compare it using balance okay what is your question go ahead what is tim's twisted this word twisting is when you turn something that two opposite directions like this so can twist okay next one again please read the four underlined parts starting with liquids one two three go all right liquids do not have their own shape this is the only way they're different from solids because this one and this one are the same as solids solids and liquids share these have them in common this is the way that liquids are different from solids just one difference okay and but they do still have fixed volume you can measure it in measuring cup moving the liquid to another container will not change its volume there's still the same amount think some of you guys saw that when you did your projects over the weekend and liquids have fixed mass you can measure it on scale okay last one you all know what's next gases okay go ahead and read these four things one two three liquid but this is the way this one is the way they are different from liquids they don't have fixed volume the same amount of gas the same mass of gas could fill 25 milliliters or 50 milliliter bottle okay because it it spreads to fill its container it can get spread and smaller okay share your homework we have time to look at three so don't take mine we are going to watch moons tomorrow because moon you actually talk about something new we're learning tomorrow called solubility which is when solid can mix with water and disappear all right so we're going to watch moon's video tomorrow so would like to watch sam's video this video is there one more person that wants their video shared you would like exactly exactly me see ray's hand and taylor swift okay that we'll do rey or taylor ray i'll try and find your video okay please listen nicely to your friends video okay they put lot of work into it so let's listen nicely to your friends video let's start with sam's hello everyone my name is sam today will make apple juice first the materials is apples three apples and the scale plastic bag the knife and last is the machine that squeeze the apple into this liquid first will use this scale and the plastic bag and three apples is how many kilograms okay now let's start it this is 54 kilograms 54 kilograms and then we'll use this knife to pop the apples 52 grams and when put it into this machine you can see 54 kilograms is how much the liters now the dangerous part is both not the waiting available so we can hear your talking you can see that this machine is squeezing this apples squeezing very good please do the water over here and the shell here the juice will be in this two grams it's equal to milliliters very nice great comparison it just changed color from red to jelly so now sam's talking about some of the properties what he can see what he can brown mixed with gelatin and its smell was sweet it taste was very tasty like apple juice out okay now it's time to pull it to the phone you see at first it was it was solid and then this squeeze it into liquid and liquid don't keep the shape of its container it's from big and then it take the shape of the big top and the small cup very good so he's saying he it changes shape when he moves it from the big cup to the small cup so it's liquid not solid and even solid you can you can break it but it is hard to break because it can be very thick and then will drink this this is yummy apple juice all right excellent work sam very very good nice job talking about the different properties of solids and liquids including smell he talked about hardness of his apples how they were hard to cut he talked about color all right nice work let's take look at sushi hello i'm susu today will make drink with liquid gases solid this is cook it has liquids which is the waterside and the gases or the bubbles nice job as well it is solid this is the warmer it is also solid this is the juice it is liquid this is the measurement this is the scale for this is the gases and sides get cooked we put the water here then we put temperature is very good property to talk about how many one two how many think yes okay 80 milliliters which is the ice and the watermelon liquid which is the juice and the coke and gasoline which is the bubbles inside inside the cake the best thing of all it's cherry bye bye thank you so song nice work suzu excellent job talk about solids liquids and gases susu used all three which is the reason one of the reasons picked cc's video sophia do you have question and can't hear you you can't hear me very well know it's it's bit quiet because it's playing on my computer could you hear little bit yeah okay all right our last one we're gonna watch today will be raise but we're gonna watch three more tomorrow moons and two more all right sadly we don't have time to watch all of them but that's why gave everyone point on class dojo ray need to add your point because you guys really did really really good job ray has two videos that one was weighing and think this one is his submarine so let's take look at this one hello everybody today i'm going to better the volume this one's different so ray this is your measuring which i'd is this one the submarine here's the submarine okay hello i'm ray today i'm going to talk about my stuff bottle balloon and some ribbons it floats wow that's so cool that's such good idea ray we leave it alone all right actually you guys have some homework tonight trying to find things that float or sink which is why was glad ray did post video of it so float is when it's on top of the water and sink is when it is heavier than the water and goes under the water banana what does float mean banana what does float mean cannot hear you okay what does float mean float it was just in rey's experiment the submarine floats and the submarine sinks what does float mean you can look back here see here banana the balloon is filling up with air okay and we can see when the balloon fills up with air it floats up banana so what does float mean banana what's the water bottle doing all right let's see if someone can help banana ceno what does float mean is like some something that go after water excellent it stays on top of the water it doesn't sink so sino what does sink it mean under the water excellent offload very good ray this was perfect everyone any questions about floating or sinking because this will be part of your homework tonight pasta is that question or is it you saying you want to watch your video question we have to find anything that floats or sinks and compare them yep yep that's gonna be your homework tonight i'll explain more let me get to that slide but yes so again any questions about float and sink okay very nice job ray ray also did some of the measuring ones but we don't have time to watch anymore but i'm sure that they were very good saw scale see you testing some volume maybe i'll skip forward bit hello put it 300 milliliters into the measuring cup is 15 the egg is 50 milliliters all right so now the water went from 300 to 350 so ray knows the egg is 50 milliliters all right and see here these are the other projects you guys worked on again we don't have time to watch every video all right we've got mix of the projects you worked on this is jack weighing his sister you guys had some really good ones blue moon also made juice he did really good job making the juice maybe we'll get to watch some more of these tomorrow so shape what is the shape of gas can anyone tell me what something that is gas shaped how about zook zuke what's the shape of gas gas don't have shapes there we go it was trick question tricked you gas doesn't have any shape good job zook there's no shape what about volume how much space does gas take up how much space does this gas take up can you tell see now have no spice good well it does take up space but it changes if we moved all the gas in this balloon to bigger balloon it would still fill up the bigger balloon the volume would change nice work ceno and mass we do know it would still be the same amount of matter even if we moved it to new balloon does anyone have something around them with gas anyone have gas around them that they could tell me about rosie can you tell me something that is gas rosie because it was invisible it has no bowling and it has masks too excellent it has mass it has no volume very very good all right and you can tell me what are let's do what our proper actually rosie already said the properties of gases nice job rosie that was great all right so rosie just did it at home very good what about liquid what is the shape of liquid what's the shape of liquid cherry go ahead exactly does the volume of liquid change when you move it to new cup milk what do you think does the volume the amount the volume of liquid change when you move it to new cup let's say pour this milk into bigger cup does the volume of the milk change no can you say full sentence please milk when the milk puts milk pour it does not change excellent very good job milk the volume and the mass how much matter there is does not change now you try at home who has liquid next to them and can answer these questions for me let's see who haven't we heard from lot today bunny do you have liquid near you yeah all right bunny can how can you tell that you have liquid next to you how do you know it's liquid because when pour it excellent do solids do that bunny no no nice work okay so he can tell me some properties of liquids jack what are some of the properties of the liquid next to you the properties of the liquid near me is it will help us to wash the hair fast excellent can you talk about maybe color smell color the glass color okay so it's clear we say clear no color what about smell does it have smell it is yummy yummy and is it thick like ketchup or is it thin like water thin thin okay so it's not very viscous know we've heard that word only once or twice it's thin not viscous all right and the last one here is solid are solids always hard sophia what do you think can you answer in full sentence no think i'm having some connection problems couldn't hear sophia that's okay though can someone give me some examples of solids that are soft because remember hardness is property misha can you give me an example of solid that is soft think is teddy bear yeah teddy bear anything else my pencil case okay yeah maybe the clothes you're wearing these feel pretty soft to me yeah no you have one it's pillow and blanket yes those are great examples you know very good so shape it keeps its shape it keeps its volume it still takes up the same amount of space and it keeps its mass let's just answer this last question what are properties of solids want to know what can you look for in solid who can list some properties we can look for for solids zoo could give me one they shake they don't change shape very good you can give me another property we can look for pasta they have their own shape that's what zuke said as well but mean i'll do an example one property can look for is the color can someone give me another one rosie taylor rosie and taylor hotness okay taylor says hardness rosie can you say another one texture so we have hardness texture color maybe we add flexibility smell okay today we learned how to talk about properties using things in our houses homework sink or float just like rey's submarine find three objects and test them in water do they sink or float please take picture of each and send it in so you should send in three pictures okay and this could be anything solids liquids okay does it sink in water or does it float you can draw write or take picture leave it up to you draw write or take picture but need proof need evidence that you did your homework you
