4th Grade Science - Back to School Theme

Andi 0:01

when you're a kid, you learn this stuff and it's like fresh and you remember all of it, but then when you're an adult, unless you go into geology, exactly. You don't need to know this. It's I feel like we talk about renewable resources all the time, but it is a funny thing to be like, do you know what that means? Yeah, really.

Sups 0:19

I'd say a megabyte, a terabyte, but that math doesn't add

Andi 0:25

can imagine like a 10 year old being really nerdy and a little brat Hello and welcome to the, I should have known podcast, the trivia podcast that can't be trusted each week. Our Quizmaster presents you with four big facts on a topic, but one of those facts is a lie and we are doing back to school this month at the Azure known podcast, And today, our Quizmaster is Tanner.

Tanner 0:47

Hello,

Andi 0:48

And Tanner's topic is fourth grade science. And we have a special format this month where Tanner's facts will be like test questions where he will give us the question and four answers, B, C, D, and then tell us the correct answer. But for one of the questions he will say the wrong answer is correct. So join me, Andy, and our other host soups, and try to figure out which question he is lying about.

Tanner 1:15

Mm-hmm

Andi 1:15

Fourth grade science. Great Oh boy. It's been a while since I was in the fourth grade.

Sups 1:20

Yeah. Yeah. It's been a while.

Andi 1:22

Fourth grade. You turn. 10.

Sups 1:27

okay? Yeah.

Tanner 1:28

Yeah. So this is fourth grade bordering on fifth grade, like a fifth grader. Definitely knows. These And then I also feel like what's weird about fourth grade science is that they go very in depth on a few topics in science class. So they would be like, yes, I just learned that this week.

Andi 1:43

Right. Cuz it's fresh for them. Yeah.

Sups 1:45

Okay, cool.

Andi 1:46

Okay.

Tanner 1:46

So it's okay if you don't get them. All right.

Andi 1:48

Well, it's always okay to get things wrong, cuz that's how you learn. Good point. But. I think you deserve some ribbing. Maybe

Sups 1:55

I wish my parents said that it's okay to get things wrong.

Andi 1:59

not

Tanner 1:59

safe environment All right. So let's start with a fun science question. Not. Something you learned in fourth grade, but I'm sure everyone knows this saying fruit, What is the power host of the

Andi 2:12

Oh yes. I know this one.

Tanner 2:15

is a classic American like catchphrase

Andi 2:18

It's like a meme. Yeah.

Tanner 2:19

Yeah.

Andi 2:19

It's the mitochondria.

Tanner 2:21

Yes.

Andi 2:21

cool. I actually don't really remember what I like learned during fourth grade science. I was obsessed with dinosaurs was really into dinosaurs. I think most kids, our age were. Jurassic park came out in the nineties and Jurassic park basically raised me. Like I watched that movie way too

Sups 2:35

much.

Andi 2:36

but that's all I remember from

Tanner 2:38

Well if you had to sum up what fourth grade science is, it's basically plants, animals and

Sups 2:43

Okay

Andi 2:43

Oh

Tanner 2:44

so Jurassic park fits perfectly in there. Yeah. All right Question number one, which of these resources is renewable? A natural gas, B coal, C nuclear energy D hydroelectric energy. The correct answer. is D hydroelectric energy.

Andi 3:06

Okay. Okay.

Sups 3:07

Okay.

Andi 3:08

Yes. I feel like we talk about renewable resources all the time, but it is a funny thing to be like, do you know what that means? Yeah, really.

Sups 3:15

And I'm wondering, does the fourth grade know what hydroelectric energy is?

Andi 3:19

Yeah.

Tanner 3:20

I looked at the Wisconsin standards for fourth grade science and one of them is energy and fuels. Humans use are derived from natural resources and their use affects the environment. Some resources are renewable over time. Others are not

Andi 3:34

okay. So that's what they would learn and they'd learn some examples. So obviously coal's not renewable. Right. And I forget the first one, natural gas, not renewable.

Sups 3:43

Nuclear,

Andi 3:44

Nuclear energy. That's kind of tricky because people often use nuclear as like another option right away from fossil fuels. Mm-hmm And so it seems like a greener energy, cuz you could put renewable and non-renewable in like green in non-green. Right. So it's weird that it's there, but that's not the right answer. But I also think hydroelectric water is renewable. Right? So like it has to.

Sups 4:10

Yeah. And also you have finite sources of uranium, which is nuclear energy. So,

Andi 4:16

But it's not made of dead dinosaurs. Like the

Tanner 4:18

Yeah Yeah. you're exactly right. Nuclear energy is a greener resource, but because uranium is finite, it is non-renewable.

Andi 4:28

there's only so much uranium in the

Tanner 4:29

Exactly

Sups 4:30

Okay.

Andi 4:31

so

Tanner 4:32

so there's your first question?

Sups 4:33

fairly confident about question number one. Okay.

Andi 4:36

Yeah. I hope.

Tanner 4:38

Let's move on question number

Andi 4:39

your teacher name? Mr. Shrink?

Tanner 4:41

Sure. You can call me that, I guess.

Sups 4:43

Yeah. Mr. Shrank

Andi 4:44

Mr. Shrank. Yeah. I literally never call you

Tanner 4:46

Dr Tanner

Andi 4:47

Dr. Tanner. Yeah, I guess I should call you Dr. Frank, who I'm not doing that. I'm not doing that

Tanner 4:52

Question number two. What is the metric system prefix for 1 million, a giga B Tara C mega D PETA. The correct answer is C mega.

Andi 5:07

Oh Lord.

Sups 5:08

mm.

Andi 5:09

Okay.

Sups 5:10

I have doubts.

Andi 5:12

I mean, I think this might be a surprise to some listeners if you're not from the us, but we do learn the metric system in school. It's just, we prefer the Imperial for stuff, but it's not like we don't know.

Sups 5:23

Okay. So you know what a kilometer.

Andi 5:26

Yeah. Okay. I know it's smaller than a mile.

Sups 5:28

okay. Yeah.

Tanner 5:29

Some of the example questions I saw were like what is the best estimate for the mass of a goat 34 grams or 34 kilograms? So it's got you thinking in units like this, right?

Sups 5:40

That's a very big difference between 35 grams and 34 kilo

Andi 5:45

Oh, I like the idea of a little 35 gram goat. a little

Tanner 5:49

but

Andi 5:49

the thing about the two systems for me and why I get irritated with, people who like to make fun of us using the Imperial, cuz it's like they're separate systems to me. Like I know them relative to each other, like, like Obviously grams and kilograms. I know the difference between that. Changing between like pounds and

Tanner 6:06

Mm-hmm

Andi 6:06

is not actually something I really need to do. Like my phone is in Celsius So I say to my mom, oh, it's like, okay, it's 30. So it's like, what is that? Like 80

Sups 6:16

mm-hmm

Andi 6:17

but like, I don't need to know that. I just know it's hot. Yeah. That's what's important to me I don't need to change it into Fahrenheit. I just need to know that that's hot. It's

Tanner 6:26

It's more functional. Yeah, yeah.

Andi 6:28

Yeah.

Sups 6:28

Could you repeat the options once again?

Tanner 6:31

Giga Tara Mager Pata

Sups 6:35

And you're saying mega is

Andi 6:37

is million mm-hmm like the lottery mega millions.

Tanner 6:40

Sure. it's redundant then.

Andi 6:43

oh yeah. Million

Tanner 6:44

million

Andi 6:45

mega gram.

Tanner 6:46

Megagrams liter

Sups 6:47

I've never.

Tanner 6:48

A

Sups 6:48

Why would you use

Tanner 6:49

yeah. Yeah.

Andi 6:51

like that's not even real. Right. Megaliter, right

Sups 6:55

but I'm think I'm thinking of like in computer bites. Yeah. You know, I'd say a megabyte, a terabyte, but that math doesn't add

Andi 7:03

definitely like terabytes are bigger than megabytes. Yeah. But that's not the question. The question is which one is million so mega kind of makes sense, But then in, if in computing, mega is smaller than Tara, there are a lot of numbers. You can have 10,000, a hundred thousand and then a million. Yeah. Cause a a million is a thousand thousand. So like, oh like I could order all of those. Yeah. but I don't know which one's the

Sups 7:26

million. So in computer terminology, if I were to order them, I would go mega mm-hmm giga Terra. Petta Yeah. Yeah.

Andi 7:35

the order I feel pretty good about, but which ones the million along that scale,

Sups 7:40

I would like to put a pin on this question

Andi 7:43

Oh okay I used to do that in school. I would circle the ones that I wasn't sure about so I

Sups 7:47

to go back,

Tanner 7:48

yeah, yeah. Question number three. What does the spleen do? A recycles old blood cells and fights infections. B stores and secretes SP C digests food and absorbs nutrients D Produces and releases hormones. The correct answer is a recycles old blood cells and fights infections.

Andi 8:15

All

Sups 8:15

Mm-hmm

Andi 8:16

I feel pretty good about that. Yeah. Spleen, it's a weird one. It's a weird organ off forgotten, you know, it Doesn't really get its due, I think. Didn't. perforate your

Tanner 8:25

I damaged it once

Andi 8:27

Yes.

Tanner 8:29

I got in a go-kart accident and tore my spleen, but I'm I was fine. Yeah. I turned out. Okay. I think

Andi 8:37

Also you don't have a gallbladder, which was, I think is one of the organs you listed its function and tried to throw us off its top the Splain.

Sups 8:45

With B option B bile.

Andi 8:46

Yeah. That's the gallbladder The liver makes bile Yeah. And the gallbladder stores it, or if your Tanner's body, then the liver just shoots the bile right into the digestive system.

Sups 8:59

okay There's

Andi 9:00

There's no

Sups 9:00

spleen Yeah. Yeah.

Andi 9:03

Spleen. Yeah. Kids learn about the spleen,

Tanner 9:05

huh? yeah. So fourth graders in life science learn about human organs and their functions. So they learn really basic stuff. Like what's the tube that moves food from the mouth to the stomach. So this is very basic stuff. Okay So I took the hardest of the organs and asked about that.

Andi 9:23

The spleen.

Sups 9:24

Yeah. I'm trying to think if I learned about the spleen in the fourth grade,

Andi 9:28

I don't really remember learning about the spleen

Sups 9:30

No, I think we did bodies slightly later, maybe in sixth grade.

Andi 9:33

Yeah. Okay.

Tanner 9:34

So you think, you know, what the other organs were that I was describing

Andi 9:38

I. Pretty good

Tanner 9:39

that's one test taking strategy, if you can rule out the other ones, because you're more confident in what they do.

Andi 9:44

Yeah.

Sups 9:45

But you know, but during a test, your default state is double guessing. So even when you know

Andi 9:51

your default status speak for yourself. Some of us are emotionally adjusted still.

Sups 9:57

Oh,

Andi 9:58

No,

Sups 9:59

not really.

Andi 10:00

I mean, I feel pretty good about the spleen.

Sups 10:03

mm-hmm

Tanner 10:03

okay. I

Andi 10:04

Too easy.

Tanner 10:04

All right. Question number four. Where can magma be found on earth? A, on the surface of the crust B in the mantle C in the liquid outer core and D in the solid inner core, the correct answer is a, on the surface of the crust.

Andi 10:25

Oh no.

Sups 10:26

Mm I'm confused because all of them sounds right, because the magma somewhere around that Was it at the center? I hope start. The

Andi 10:35

Well, the center's solid, so it definitely doesn't come from that because MEMA. Is a liquid. So definitely not the inner core but you could have told me the outer

Sups 10:45

the core

Andi 10:45

and definitely I would've said the mantle. Yeah. So now I'm like, oh no, what exactly is magma? And also we did an episode on volcanoes and I'm pretty sure this came up and I do not remember the difference between magma and lava. Yeah. Lava's flowing. Magma is just the stuff. Yeah. It's like liquid rock mm-hmm

Tanner 11:09

that's right. MEMA is, as fourth graders would learn it extremely hot liquid and semi-liquid rock.

Sups 11:15

Yeah.

Andi 11:15

But doesn't it come from the mantle

Sups 11:18

I mean, it's one of the contents of lover when the lava is flowing, right?

Tanner 11:22

it's it depends on your definition.

Andi 11:25

So like you know, I think you just caught him in his lie. I bet it's MIMA when it's in the mantle and lava, when it's up here on the crust. Yeah. So I'm thinking maybe that's the thing, but then we have to believe that mega not

Sups 11:42

nah Yeah. Woo.

Andi 11:44

Wow. That's tricky. Okay. Yeah. I feel like this is a question where it's like, I really should know this, but I'm not nearly as confident as I think I would've thought,

Tanner 11:56

yeah, Fourth graders spend a long time on the rocks, right. And the layers of the earth geology. And in Wisconsin, this is especially taught because we had glaciers come in and change the geology of the state.

Andi 12:09

I remember we learned about the major geological sections of the state of Wisconsin Like it's a geologically weird

Tanner 12:18

It is. Yeah.

Andi 12:19

And I guess I never really. Appreciated that you know, yeah, when you're a kid, you learn this stuff and it's like fresh and you remember all of it, but then when you're an adult, unless you go into geology, exactly. You don't need to know this. It's not important to your life. So this is pretty tricky. But before we guess which one you're lying to us about, can you repeat your four questions and the answers

Tanner 12:41

mm-hmm Question number one, which of these resources is renewable? A natural gas, B coal. C clear energy D hydroelectric energy. The correct answer is D hydroelectric energy question number two. What is the metric system prefix for 1 million, a giga B Terra, C mega D PETA. The correct answer is C mega question number three. What does the spleen do? A recycles old blood cells and fights infections, B stores and secretes bile, C digests food and absorbs nutrients D produces and releases hormones. The correct answer is a recycles old blood cells and fights infections. And question number four, where can magma be found on earth? A, on the surface of the crust B in the mantle C in the liquid outer core D in the solid inner core, the correct answer is a, on the surface of the crust. One of those would be incorrect.

Andi 14:18

Oh God.

Sups 14:19

Good thing is that we are relatively confident about two questions. So let's rule out one and three for the

Andi 14:26

time Yeah, I feel pretty good about those. Yeah.

Sups 14:28

So now it's between two and four mm-hmm

Andi 14:31

mm-hmm

Sups 14:31

I am more inclined towards two.

Andi 14:35

Okay.

Sups 14:35

Cause I'm thinking it's giga.

Andi 14:38

Yeah, that's a hard one. mega would not have been my first guess. But I also don't know. Yeah. So like, I was even trying to puzzle it out with like the roots, like in Latin and not super helpful. So I really don't know that one Yeah. Mega sounds decent. Yeah. but also then what are the other ones? is there a 10,001? Is there a hundred thousand

Sups 15:01

I think there's a hundred

Andi 15:02

thousand. I think we just do a thousand and then we guess we go to a million, right. I mean, I don't even know for number two. But I think maybe with number four, maybe

Sups 15:12

the mental,

Andi 15:13

magmas from the

Sups 15:14

mental Yeah. That's that would be my second guess.

Andi 15:17

But I'm not sure, like maybe he's playing off the idea. They're like, oh, people erroneously call lava MEMA, but maybe not. I don't know. Okay. We have to pick ones wrong. So I'm gonna say it's

Sups 15:29

that one. Okay. So I'm gonna go with number two.

Andi 15:32

Okay.

Tanner 15:32

All right. Answers in the lie is question number for.

Andi 15:38

Oh, okay.

Tanner 15:39

For exactly what you were saying, magma is in the mantle mantle, and when it comes onto the Earth's surface, it is called lava.

Andi 15:46

Okay I feel like I can imagine like a 10 year old being really nerdy and ki kind of a little bit of like a, a. Audacious. a little brat and being like actually it's lava on the surface,

Sups 15:59

Yeah.

Tanner 15:59

You did catch me in that. What's the difference between that

Sups 16:01

yeah, yeah, exactly.

Andi 16:02

Yeah Then, but I do wanna go to back to question number

Tanner 16:06

two. Yes. Let's talk about number

Andi 16:07

two. what do they mean? Those

Tanner 16:09

So if we go through them, DECA is 10. Heto is hundred. Yeah. Kilo is thousand. And then they start counting in thousands of thousands right? Like you said, there is no

Andi 16:23

Uh

Tanner 16:23

it's a thousand

Andi 16:24

sense So a thousand so a million then is mega mega.

Tanner 16:27

then is

Andi 16:27

one Okay

Tanner 16:29

thousand. Megas. Yeah. Is giga. A thousand giga is Tara a thousand Taras is Petta. And yeah

Sups 16:38

Okay So I got the order.

Andi 16:40

Yeah Yeah. We were right about the order. Yeah. But it was, but that was confusing because it's like mega seems too low. Yeah. If it's so close to kilo

Tanner 16:49

right Because the, pattern changes with mega yeah.

Sups 16:52

straight from a hundred to thousand and then thousand of thousand,

Andi 16:54

Well, yeah, you stop going up by tens. You start coming up by thousands and then that's, that's tricky. Yeah. And it also makes sense why we wouldn't hear it very much because it, or like it's in computing. mm-hmm Because that stuff grows exponentially. Right. Right. Whereas like weight of things on the planet earth don't really go up that way. And so, like, it's not useful to be able to talk about giga grams. Yeah. Like, would that be useful? Like what could possibly weigh a gig? Agram I don't even know. Like, that's just, And I think that's also kind of a funny point about people who are really pedantic about the metric system, which obviously, if you can't tell

Sups 17:29

yeah.

Andi 17:31

I have a bit of a Chibo on my shoulder because ultimately all these things are arbitrary and like yeah. Your system goes up like logically by units of 10, but they're useless. At a certain point, right? It doesn't matter that they're perfectly organized in these like this perfect nesting dolls of units. Yeah. If they're not useful right. Which is why you can hate on the Imperial system, all you want, but it's clearly useful to some people mm-hmm

Tanner 17:55

mm-hmm

Andi 17:56

and ultimately all measurement is arbitrary.

Tanner 17:58

Yeah. It's about like how useful it is. how functional is any of this knowledge, you know?

Sups 18:03

Well, yeah, it was helpful in the, I should have known podcasts

Tanner 18:06

Yeah, absolutely.

Andi 18:08

I would kind of like to know if any fourth graders would be like, oh, I

Sups 18:12

thought that.

Andi 18:12

was easy.

Tanner 18:13

Yeah,

Andi 18:13

But wow. I should have known,

Sups 18:15

I should have known,

Andi 18:16

Thanks for listening to this episode of the, I should have known podcast. If you listen to podcasts on apple and you would like to give your teachers an apple, please leave us a review because it really helps us out. And as always, thanks for listening. Spleen.

Sups 18:33
