Scholars, I wonder if you know:
Will it sink or will it float?
Just sing this song and don't forget
That water really is wet
So when you engineer a boat,
Will it sink or will it float?
It's all about the density
D = M over V
The mass is the amount of stuff
And volume, space that it takes up
So when you engineer a boat,
Will it sink or will it float?
Will it sink or will it float now?
Will it sink or will it float now?
You need to maximize displacement
Or else you'll sink down to the basement
So I wonder if you know...
And Archimedes said, "Of course!
The water has a buoyant force!"
A quick experiment will prove:
One gram per centimeter cubed.
So when you engineer a boat,
Will it sink or will it float?
So let's be sure to get it straight:
Floatation ain't about the weight
A heavy ship can float on top
A penny sinks just like a rock
So when you engineer a boat,
Will it sink or will it float?
Will it sink or will it float now?
Will it sink or will it float now?
You need to maximize displacement
Or else you'll sink down to the basement
So I wonder if you know:
Will it sink or will it float?

Climate change, climate change
It's more than global warming
Scientists are warning
What could be to blame?
Climate change, climate change
Hurricanes and fires
Water's getting higher
Weather's getting strange
Climate change, climate change
So much carbon dioxide
Melting glaciers worldwide
Isn't it a shame?
Climate change, climate change
But we can save the planet
If we understand it
What is climate change?
Do you ever think that the Earth is just right?
In summer, lots of sun; in winter, lots of ice
It's true that every day the weather can change
Seasons come and go, but the climate stays the same
Our planet's atmosphere has a mixture of gas
To trap that solar warmth, like a greenhouse made of glass
Without it, we would freeze. All the heat would escape
But too much greenhouse gas can make our climate change
I know you love those fossil fuels
Like coal and natural gas and oil
We use them every single day
To make heat and electricity
But the carbon dioxide they release
Is trapping too much solar heat
We're doomed if we don't stop the burn
When will all these people learn?

If we understand it
What is climate change?
The climate of the earth wasn't always this way
In fossils from the past, we can see how it changed
Three hundred million years was a long time ago
The carbon in the air made it hotter, don't you know
With warm and humid air, there was no type of snow
The dinosaurs evolved, and enormous plants did grow
And when these giants died, they decayed underground
Their fossils turned to fuel that the humans later found
I know you love those fossil fuels
Like coal and natural gas and oil
We use them every single day
To make heat and electricity
But the carbon dioxide they release
Is trapping too much solar heat
We're doomed if we don't stop the burn

Constant of proportionality
We're multiplying constantly
In tables, in equations, and in graphs
Look for proportionality
To comprehend reality
To understand proportions, you need math!
Let's start with a table: we'll have to divide
Make certain the numbers are on the right side
It could be dollars earned per hour
Or touchdowns scored per game
In proportional relationships, the constant is always the same!
Constant of proportionality
We're multiplying constantly
In tables, in equations, and in graphs
Look for proportionality
To comprehend reality
To understand proportions, you need math!
Now how 'bout a line graph? That's easy as pie!
It starts at the origin, then climbs to the sky
Find x = 1. That's your unit rate.
y there is the constant, no need for debate.
Another method you can use:
Find an ordered pair to choose.
Divide the second by the first --
Be careful, don't get it reversed!

Rise over Run
02:38
|

Climbing up a mountainside
Hanging on by a rope
Two steps up and one step right
I won't fall down, I hope
When I saw a warning side
That said "Increasing Slope"
I calculate the unit rate.
Math can help me cope!
Oh, let me show you how to find the slope:
Plot two points, then count rise and run
(Rise over run)
Oh baby, slope is just a ratio
Rise and run and you're almost done
Rise over run)
Zooming down a waterslide,
Picking up that speed
It started very gradually,
But now it's getting steep
Every yard I zoom along,
I drop a yard in height
The slope it gives is negative,
Falling left to right
Oh, let me show you how to find the slope:
Plot two points, then count rise and run
(Rise over run)
Oh baby, slope is just a ratio
Rise and run and you're almost done
Rise over run)

Let's Talk About Slope
02:47

Let's talk about slope, baby
y = mx + b
Begin at the intercept, then rise and run
It's so easy!
Let's talk about slope
Let's talk about slope
Let's talk about slope for now
To the scholars at home or in the crowd
It keeps going up or down
Don't confuse, abuse, or refuse the topic
'Cause that ain't gonna stop it
Now, we talk about slope on the slides and amusement park rides
Many will know: it's how a line goes
Let's tell how it rises and how it runs
Where it starts -- it's so much fun!
Those who think it's boring have no choice:
Pick up the pencil, press play, and turn your thinking cap on
Nothing can stop a scholar
All right then, come on, kids
Let's talk about slope, baby
y = mx + b
Begin at the intercept, then rise and run
It's so easy!
Let's talk about slope
Let's talk about slope
Fifty dollars in my savings account
And every Saturday, I deposit the same amount
Ten bucks a week, now that's a constant rate
This line's increasing steadily, so go on, let the haters hate
Per, each, every, daily, or yearly
These are the key-words to help you severely
They mean slope or speed, rate of change
Rise over run, or m -- you know they're all the same
But what about b? That's where it begins, it's true
The starting point, fixed cost, or initial value
The line intercepts the y-axis
And if you're confused, that's why we're gonna practice
You know lines that are parallel
Never intersect. They've got the same slope, very well
Then on the other hand you have the perpendicular
90 degrees, slopes are opposite reciprocals
Straight lines, constant rate of change
And you'll always recall, I hope,
That slope is dope
Let's talk about slope, baby
y = mx + b
Begin at the intercept, then rise and run
It's so easy!
Let's talk about slope
Let's talk about slope

Move the Decimal
02:43
|
|||
To the left, to the left
Negative exponent, move to the left
Scientific notation
More than zero, less than one
From the width of a human hair
To the mass of a molecule of air
Protons, neutrons, and electrons
One PPM, that's one part per million
Circling the decimal because I'm not a fool
Every time I see the sign, I know the rule:
I'm gonna say
Just move that decimal, just move that decimal!
It could be a tenth, a hundredth, a thousandth
It could be a millionth, billionth; counting places
Just move that decimal, just move that decimal
It could be a trillionth or a quadrillionth
When you're working with scientific notation,
Just move the decimal
To the right, to the right
Positive exponent, move to the right
Scientific notation
To infinity and beyond
From the length of the Milky Way
To a galaxy far, far, away
Population of our nation
Everybody loves scientific notation
Circling the decimal because I'm not a fool
Every time I see the sign, I know the rule:
I'm gonna say
Just move that decimal, just move that decimal!
It could be a ten, a hundred, a thousand
It could be a million, billion; counting places
Just move that decimal, just move that decimal
It could be a trillion or a quadrillion
When you're working with scientific notation,
Just move the decimal

Remix (Exponents)
03:08
|
|||
All right now, everyone listen:
I got a song with precision
We got some rules for these exponents
I'm a mathematician
We've got square roots and cubes
And orders of magnitude
I'm an exponent proponent
Let me sing it to you
Exponents are your friend
When you need to comprehend
Multiplication and division
Again and again and again
It all starts with the base
Gonna raise it to a power
Before you know it, you're in space
At half a billion miles an hour
So watch me simplify
Watch me evaluate
I am an expert, it's true
With all these exponent rules
Yeah, I know just what to do
All right now, everyone listen:
I got a song with precision
We got some rules for these exponents
I'm a mathematician
We've got square roots and cubes
And orders of magnitude
I'm an exponent proponent
Let me sing it to you
Now when you have to exponentials
You know they have some potential
When the bases are the same
Come on and sharpen your pencil
With a product of powers, here's the rule of thumb:
Just take your exponents and find the sum
Example: 10 to the sixth times 10 to the fourth
Equals 10 to the tenth. Need I say more?
A quotient of powers is a simple action
Remember division can look like a fraction
You already know that the base doesn't change
And for the exponents we can use subtraction
So watch me simplify
Watch me evaluate
I am an expert, it's true
With all these exponent rules
Yeah, I know just what to do
All right now, everyone listen:
I got a song with precision
We got some rules for these exponents
I'm a mathematician
We've got square roots and cubes
And orders of magnitude
I'm an exponent proponent
Let me sing it to you
A zero exponent will be one-of-a-kind
Except for zero to the zero, which is undefined
And a negative power means we're dividing by the base
It's the reciprocal, with the base in the denominator place
For a power of powers, here's the explanation:
Combine the exponents using multiplication
There's only one base, so it stays by itself
Remember this song if you need exponent help!
So watch me simplify
Watch me evaluate
I am an expert, it's true
With all these exponent rules
Yeah, I know just what to do
All right now, everyone listen:
I got a song with precision
We got some rules for these exponents
I'm a mathematician
We've got square roots and cubes
And orders of magnitude
I'm an exponent proponent
Let me sing it to you
