Lesson 6: The Lecture

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 six

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 a third

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

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 six and to go back over lesson four

Practice carefully, and you will be ready

For the new techniques and new situations

We will cover together in lesson five
