This is my groups bridge. What we did is made it all out of newspaper. We used triangels because it makes it stronger we also used tape so we could keep it together and it help it so it would stay up.What we did at the top is put four rolls and taped them at the top and the desk because it would hold on to the table and give it support. At the buttom we rolled pices of newspaper and then tape them together. In the middle of the tower we put 5 or 6 rolls in the middle then we put a pice of newspaper over top. When we were all done we put wieghts on them ares held 750 grams. I leared that the more supporte and triangels you have it is more stronger.



This is our house it is made out of popsicles. What we had to do is make 2 floors and a roof. What we did on the 2 floors is put popsticks facing side ways. Then we put popsicles facing up. Then we glue it together. On the roof we put 3 popsicles and glued them together and put them on an angle.Then on the side of the roof we divided it up into triangles so it is more sturdy. After we were done we glued it on to the buttom of a checkers board. Then after we put flowers made out of the ends of popsickls and coloured them. Then we were all done and put them on display.

This is my groups egg holder. What we had to do is try not to let the egg crack from dropping it up in the air from 5 feet tall. What we did we made a cube out of little pieces of wood. Then we tied elastic bands around the little pieces of wood at the top. After we made a little cube around the outside of the egg made out of straws.We put three on each side. Next we put straws around the inside of it for when it got dropped. When we were done we teted them but ours cracked a little. Thats what we did to make pur egg holder.

EXTARCTION
The natural resources of a crayon are Puraffin Wax, dye, pigment and chemicals. They get the pariffin wax from plants that died millions of years ago and decomposed and turned into an oil.



PRODUCTION
The Crayon is made by getting a piece of paraffin wax and melting it like a candle. Then after dig it out of the container. After put it in a barle and put some water, pariffin wax and Casta surgar and also dye's. The liquid is then poured into a machine. It forms the crayon into its shape. Next a blade comes and scraps off the excess part of the Crayon. Once this is done, a machine puts the crayons into a big box so people can sort them.Next they lable the Crayons of where they were made and the colour of it. Then a machine puts the crayons into different sizes of box's. After they get transferred to different stores.



DISTRIBUTION
The Crayons get shiped by trucks and plains to stores like Walmart and Toys R Us. Then the Crayons go on shelves to be sold. Once the Crayons are purchased the buyer takes them home to use them. The most detrimental consequence of distribution to the enviroment is the pollution to the air from the vehicles used to transport them.

**USE**
The Crayon is used for colouring and sometimes people melt them on a peice of paper for fun! The Crayon can last for a few years inless you use it all the time. But then once it is all used up you end up having to buy more and it just keeps going on and on.

**DISPOSAL**
Once the Crayon gets old or broken they take the Crayon and make it into a stick but it still is a Crayon. Also it is not the same shape but it is still good to use. The Crayon does not useally break down because it is melted down to make a new Crayon. The Crayon can be recycled because then they turn the Crayons into stick ones so then people can still use them and it is not effecting our earth as much. The consequences of the diposal are that we are helping our earth by useing them over so we don't polute our earth. The Crayon will advenchly run out because it is made out cruode oil.



This is a type of energy me and my group made. Its called a Windmill. I learned a lot about energy from making this windmill. I also learned that when you turn the wheel it is useing kenetic energy.The type's of energy weused to make the windmill are kenetic, food, and sun.How it works is it goes from kenetic from us then we get the food from the sun so it gives us energy.When we built the windmill we didn't make any energy we didn'tdestroy enerygy we just transformed energy.So now if you didn't know much about energy you should now.That's how we transformed different kinds of energy.
