Here is what I learned during our sudy of Structures and Mechanisms.this is our groups bridge.We came #2 in the bridge building compatition, 8000g nice.I learend that having those long sticks to hold the bridge up the bridge was a very good idea because it takes the whight and to the table so that the bridge doesent just colapse in the middle. this is our popsicle stik house we came #1 place ya!I think that the thing that made our house stand up strong was the thick corner beams.in the end the walls wernt even supporting the whight of the roof! but if you push on the roof the corner beams will take the whight.

this is our egg protector we came #1 ya! our egg dident break I think because we dident have any elastic band bungy strings.

__To____othpicks__

__Extraction__

Toothpicks come from berch trees, whitch are found all around north america but the problem is that we are cutting down to many trees.

__Production__

A factory cuts the berch trees into logs then the logs get debarked and the excess bark goes to another factory where it is used as fule so thee is no waste material in the process.

__Distribution__

Toothpicks are sold almost every where,and the only enviromental cosequence is that the plastic cases are throne out and sent to the land fill and willlast forever

__Consumption__

Toothpicks are usaly kept on a shelf untill somwon picks there teeth with them.

__Disposal__

We thro out our toothpicks into the garbage and then they go to the lonfill and return to the earth and then we can keep making toothpicks. The only enviromental consequens is the pakage that lasts forever in the ground.

I leared many things during the energy tranfermatoin experaments. I learned that all of the energy in the worold comes from the sun, also that energy cannot be created or destroyed. We (group 4) made a water wheel witch tranformed gravitational electricity, into kenetic electricity. Those are some of the things I learned about electricity.
