i have to build a model of gallium (ga) for science. It should be made out of household materials, but i can do a little shopping. anything as far as like sprinkler equipment or something would work.

the basic parts i need are:
1. 31 protons---ANYTHING will work
2. 39 neutrons----ANYTHING will work
3. 4 progressively larger rings for the 4 energy levels or shells.
3. 31 electrons to fit on the rings. i need 31 here.

one plan i had was to use bolts stuck into a stryafome ball as protons and neutrons then washers as electrons. I really have no idea what to use for the rings.

also, it has to be strong so no candy models or anything. my science teacher doesn't want to have a bunch of protons rolling around.

thanks
please be creative.

ANYTHING works

This is from Chapter 9, Exercise 9-4, #37 of Fundamentals of Technical Mathematics (2nd edition): The formula for compound interest is A = P(1+i)^n, where A = amount after n interest periods, P = principal (the initial amount), and i = interest rate per period. How many years will it take for money to double when it is compounded yearly at 6 percent per year? (Hint: Let A = 2P.)

This is due by Thursday Dec. 6th. I need a poem about 8th grade life and stuff...about me coming to a new school from a different place and experiencing a lot of changes...blah blah
blah.

THE POEM I USED BEFORE FOR THIS CLASS

Breath for me, show me the way,
reveal my path, I'm here to stay.
I used to follow, 3 feet behind,
I used to listen, some intentions inside.
Tension building, anticipation non stop,
my thoughts were filled, It wouldn't stop,
But I always loved, I was always there.
Rage to sickness, love to life,
my world changed, did it fall apart?
Pleasure like no other, all thoughts aside,
My mind was freed, but frozen inside.
I chose my path, but was it right?
Now I am alone, breathing on my own,
happiness at side, my soul forever owned.

-Please, someone, anyone, help me with this poem....please!
