Lesson 6: The Lecture

Edit

Okay, let's begin

Compound, a substance composed

Of two or more elements

Chemically combined

In definite proportions by weight

Mixtures, two or more substances

That are not chemically united such as air

Solution, a uniform mixture of varying proportions

Of a solvent and a solute

For many of our students

This is the lesson you've been waiting for

Lesson 6

Left channel, right channel

Hydrogen, H plus one

Sodium, Na plus one

Magnesium, Mg plus two

Aluminum, Al plus three

Potassium, K plus one

Calcium, Ca plus two

Chromium, Cr plus two, three, six

Any physical difficulty

With a record or a turntable

Is taken care of

Do you think that Led Zeppelin

And Frank Sinatra would go together?

Edit, no combinations of music

You're about to play a soul, 45 rpm recording

But the turntable is set at 33 and 1/3

And the record plays very slowly

Let's pick up the tempo a bit, eh?

Now, let us imagine

That you are in the middle

Of your disk jockey program

This is the mark of a professional

Yeah, if you could throw a couple yeah, uuh

Right, when he's playin' the drum, you know

Let him play a couple beats alone, euh

Uh, oh, I'm sorry I had the turntable at the wrong speed

Aah, listen to this, scratchin', the greatest thing on earth

What do you do? What do you do?

Toggle, wow, drop

Chemical change, a change that alters

The composition of the molecules of a substance

New substances with new properties are produced

Drop

From now until your next lesson

We want you to study carefully every section

Of lesson 6 and to go back over lesson 4

Practice carefully, and you will be ready

For the new techniques and new situations

We will cover together in lesson 5
