Magic Beans

The Amazing Magic Bean Discovery

Recently scientists at morrison labs found a way to turn metal into plastic. Our scientists used a top secret bean to do the amazing transformation.

All you do is place the metal ball on top of the magic beans and then shake them.

In just a few seconds the metal ball sinks and a plastic ball appears.

OOH, AHHH!

Voila'! The metal has been tranformed into plastic!

This distinctly neato discovery is sure to bring us the Nobel Prize for chemistry.

1. Principle: If you pack more mass into a the same volume, it's more dense.

The density demo below comes from the Fun Based Learning Web Site.

You are on vacation and you have packed your suitcase.

Wow that's an old-school suitcase. It doesn't even have any wheels!

You back everything neatly for the return trip home...... but wait, there is a serious problem!

AAAAAAHHHH!

During your trip you could not resist buying some cool souvenirs.

I need to get all my cool souvenirs into this darn suitcase.

This just isn't working! Maybe if I sit on the suitcase it will close?

Hmmmmm......

All my stuff doesn't fit!

D'oh!

Patrick's volume is causing some serious packing problems! He needs to lay off of the Krabby Patties!

What a volume dilemma!

Common experience: going on vacation, suitcase is too full to close

Show an open hardtop suitcase that you're taking on vacation (full of clothes). Close it, then get a student volunteer to come up and lift it. Then open the suitcase, and talk about how you always get sucked into buying stuff while on vacation while tossing a bunch of tacky souveniers and other knickknacks you've bought on vacation in. Then ask another volunteer to sit on the suitcase to help cram it shut and do up the locks (you want it visibly too full, and for them to see things are getting compressed). Ask the original volunteer to lift the suitcase again. Is it heavier? (yes). Ask the class - did the mass change? (let them debate it out until they come up with a consensus of yes, it increased). Then ask the class if the volume changed (no, it's the same volume inside). Is it more or less dense? (at this point, only a few students will know it's more dense, so state it is more dense - if you put more mass into the same volume, it's more dense). Write this principle down on the board.

In addition to the density demo above our scientists recently changed the density of a cubic meter by stuffing volunteers into it. It's amazing what our scientists will do for the good of humanity!
