Bacteria
Oh, lacking any nucleus, you do have a cell wall
You live in water, air, and soil, and anywhere at all
You reproduce by fission, and you do so very fast
And under harsh conditions in an endospore do last
For decomposing things that die, a saprophyte we need
But some are parasitic: on a living host will feed
For taking nitrogen from air, and fixing it into
The soil for plants to use, I’m sure they’re all grateful to you
In dairy products you have shown yourself a cultured friend
And to genetic engineers, your DNA you lend
You even help to fight diseases caused by your brethren
You make antibiotics which destroy or weaken them
Though most of you are helpful in some of these mentioned ways
There are a few who have to do a bit with some disease
Producing toxin, or the cells attacking directly:
Diphtheria, pneumonia, strep throat, tetanus, and TB
We do appreciate you and your praises we do sing
Yet some of you make life so hard with troubles that you bring
Our food you spoil, our crops you rot, our animals attack
With botulism, different rots, cholera, and anthrax

Molecules
Everything is made of something.
Everything has basic parts.
Everything is made of molecules.
That’s where things all start.
Molecules are made of atoms.
Each one has a special shape.
Molecules are small particles
Of all things they are great!
Fish and rocks, and trees
The mountains and the seas
Tables, cars and cheese
All have molecules!
Molecules can be organic
And they help form living things.
There are also inorganic molecules
In many things.
Molecules move when they’re heated.
When they’re cold they move so slow.
They’re a part of our Earth’s chemistry.
Now everybody knows!
Broccoli, flies and fleas
Roads and glass and peas
Even you and me
All have molecules!
Everything is made of something.
Everything has basic parts.
Everything is made of molecules.
That’s where things all start.

Sound
Sound, sound, sound,
What is sound? What is sound?
Sound, sound, sound,
It’s a vibration travelling around.
The sounds we hear are everywhere
Moving in waves through the air.
Travelling through solids and liquids too,
So many sounds old and new.
Sound, sound, sound,
What is sound? What is sound?
Sound, sound, sound,
It’s a vibration travelling around.
Some sounds are high
And some are low
If the vibration is fast or slow.
The fast sound high, the slow sound low.
When you hear the pitch,
You will know.
Sound, sound, sound,
What is sound? What is sound?
Sound, sound, sound,
It’s a vibration travelling around.
The sounds you hear from far and near
Vibrate the bones inside your ear.
The message travels to your brain
And the sound you hear is explained.
Sound, sound, sound,
What is sound? What is sound?
