The Reproduction Song
Click here to listen to the song
Mr. Stuart:The parts of a flower are so constructed that very, very often the wind will cause pollination.If not, then a bee or any other nectar gathering creature can create the same situation.Yes, anything that gets the pollen to the pistils, write it on the list.I'll try to make it crystal-clear: The flower's insatiable passion turns its life into a circus of debauchery!
Mr. Stuart: Now you see just how the stamen gets its lusty dust onto the stigma.
And why this frenzied chlorophyllous orgy starts in spring is no enigma!
We call this quest for satisfaction a what, class?
Sorority girls: A photo-periodic reaction!
Mr. Stuart: Oh, that's good, that's very good.
Hey, I'm lost where are we?
Chapter 2, page 5...
Reproduction, reproduction!Put your pollen tube to work.
Reproduction, reproduction!Make my stamen go berserk.
Reproduction!I don't think they even know what a pistil is!
I got your pistil right here...Where does the pollen go?
Mr. Stuart: Next chapter. In an abstract way, the same thing applies
To the reproductive organs of the more complex life forms.
But now we are dealing with sexual response.
Are there any questions before we begin reading?
Is it possible the female member of some sex on a couch?
Could like get this guy all hot and she never even knew it?
When a warm-blooded mammal in a tight little sweater
Starts pullin' that stuff, is she sayin' that she wants to do it?
Johnny: Can't prove it by me, cause they change their tune
When you got 'em in the back seat.With his heart beatin' fast!
Sorority girls: They make it sound like a track meet, gross!
Yeah, then all they can do is say "No, no, no, no, no, no, no, no, no!"
Reproduction, reproduction! Baby, give it to me now.
Reproduction, reproduction! Is that all you think about?
Reproduction! Come on baby show me that you really love me so!
Ohhh, I think I'm gonna throw up!
Where does the pollen go?
Mr. Stuart:The human is the only being capable of consciously controlling its number of offspring.
Any comments on this?
Paulette: Mr. Stuart, is it true that guys like you, you know, mature and all,
Carry some protection with them for sexual occasions?
Johnny: What's the big deal? Can't a girl just do that thing in a book
Where she adds up the days of her, uh, what do you call it, mentalstration?
Oh, that's really neat!
Yeah, and what will the guy say when the numbers don't add up right, huh?
Yeah, yeah, yeah!
Reproduction, reproduction! Hope he's proud of what he's done.
Reproduction, reproduction!He was only pokin' fun.
Reproduction! See what happens when a boy and girl
Don't know how to play it safe?
Reproduction, reproduction!
Reproduction, reproduction!
Reproduction, reproduction! Reproduction!

What you need to pass the IB
Here is some information to explain what you need in order to pass your IB:
*At least three subjects must be completed at Higher Level (HL) and three at Standard Level (SL).
*Should four subjects be completed at HL then only two need be completed at SL.
*All six subjects must have been awarded a numerical grade higher than 1, with a minimum total score of 24.
*The CAS requirement of 150 hours must have been completed.
*The Extended Essay and TOK course must have been completed and essays submitted.
*Additionally a grade D or better must have been awarded in either the Extended Essay or TOK.
*If the overall score is 24-27, there is no grade 2 at HL and not more than one grade 2 at SL; if the overall score is greater than or equal to 28, not more than one grade 2 at HL and no more than two grades 2 at SL; altogether, there are no more than three grades 3 or below.
*At least 12 points (12 for overall score 24-27; 16 if four HL subjects are taken) must have been gained on HL subjects, and 9/8 (6/5 if only two SL subjects are taken) on SL subjects.
*The final award committee has not judged the candidate to be guilty of malpractice.
*A minimum amount of hours must be achieved per year by students in order to pass. If an excessive amount of hours are missed, they may have to resit the year.

How nerve impulses travel
Hip hip hooray.... for DNA
by Peter Weatherall
In every living cell,
There’s a useful tool,
Containing information,
In a molecule.
Chorus:
Hip Hip Hooray for DNA,
It provides the key,
To the plans for making,
Everything in you and me.
A single strand of DNA,
Can alphabetically,
Be sequenced by the letters,
A, C, T and G.
Chorus
The letters can be put into groups of three,
Which go to make a genetic recipe eeeee,
Cells can use this recipe,
Written down in genes,
To decipher how to make,
All of our proteins.
Chorus
Proteins can be used
To make body parts,
Such as lungs and livers,
kidneys and heaaarts.
Chorus
….To the plans for making
Everything in you and me.

The Story of Ernest Rutherford
Ernest Rutherford came up with his "orbital model" of the atom while working at Manchester University. He also did a series of experiments with radioactivity, and was awarded the Nobel Prize in 1908.
Have a look at this video which explains some of his work:
Natural decay (The Radioactivity Song)
By Mark Rosengarten.
listen to the song
The nucleus of an atom is filled with lots of stuff,
There's protons and there's neutrons, thats really quite enough,
But sometimes an atom has too much of one of these,
And lets slip out decayed particles, kind of like a sneeze.
Its decay,
Natural decay,
HOORAY!
Its decay,
Natural decay,
HOORAY!
Some nucleii spew out whats looks like helium,
It's an alpha particle, made by uranium,
It's nuclear notation, it is 4,2 He,
And it is really dangerous, causes burns to you and me.
It's decay,
Alpha decay,
HOORAY!
It's decay,
Natural decay,
HOORAY!
Nucleii like C14 give a little, biddy sneeze,
It's a beta particle, an electron if you please,
It can travel fast, but it don't take much to stop,
Turns a neutron to a proton, watch the Geiger counters hop.
It's decay,
Beta decay,
HOORAY!
It's decay,
Natural decay,
HOORAY!
Isotopes of potassium emit a positron,
Its called beta positive, don't know who's side it's on,
A proton becomes a neutron, the mass remains the same,
And that is how the positron plays the nuclear game.
It's decay,
Positron decay,
HOORAY!
It's decay,
Natural decay,
HOORAY!
When a nucleus emits any of these,
It can also give off gamma,
With instability its easy,
It goes at the speed of light, 'cos that's really what it is,
And it has no mass or charge,
Only lead can stop it whiz.
It's decay,
Gives off gamma rays,
HOORAYS!
It's decay,
Natural decay
HOORAY!
