Why? (Wonders of Science)

I know a curious little boy
Who is always asking, "Why?"
Why this, why that, why then, why now,
Why not, why by-and-by?

He wants to know why wood should float?
Why lead and marbels sink;
Why stars should shine and winds should blow
And why we eat and drink.

He wants to know what makes the clouds,
And why they cross the sky;
Why the sun sinks behind the hills,
And why the flowers die.

He wants to know whywind should come
From out the bellow's nose;
Why pop-gun should go pop and
Why the ocean ebbs and flows.

He wants to know why fish have gills,
And why boys cannot fly;
Why steam comes from a kettle's spout,
And rain falls from the sky.

He wants to know why coal should burn,
And not a bit of stone;
How seeds get in the apple-core,
And marrow in the bone.

He wants to know why ice should melt,
Why spiders eat the flies;
Why bees should sting and why the yeast
Should make the bread dough rise.

Some of this Whys are not too hard
To answer, if you try;
But others - no one ever yet
Has found the reason why.
