This is my Science Page.

Here is what I learned during our study of Structures and Mechanisms. media type="custom" key="21099186"

This was are bridge. I learned that bridges need sport under them so they can let car go acros. If they didn't all the cars and trucks would fall off and all the people would die. If we got to put more things on are bridge I would put more posts on it and little ralling so the car could not fall off.I made sure that every thing was tape down so it would not fall. We used news paper and a lot of tape to hold it down.

This is are house.We made sure that wind and other forces could not brack it. The walls (to me) seemde like the real wons in are houses. We had to get working on the roof the last time because we spent a lot of time on the little pateo in the front we had to rush on the roof or we would get a very low grade for not having I roof.

this is are egg protector.

this is a progect we did in class it was a cemcal change because it changed in colour and in smell. in this progect we use stell wool, vinger, salt, suger,water and procsade. It was a cemmcal change. With the procsade it changed colour. The vinger changed in smell. The water is not a cemical change because it did nothing media type="custom" key="21545208" Before I start this is the video for paintballs. media type="custom" key="21545188" align="left"Paintballs are made from clay and pigment.Clay is for the shells and pigment for the paint. EXTRACTION. They obtained clay and pigment from the ground. They get the clay and pigment by paying miners go diging around for it untill they find it for the workers. Some environmental consequences are by dig around for clay and pigment all the time they start to move rivers, get rid of animals and nature by diging up space for them.PRODUCTION. The paint is a chemical change because you can't turn paint back into pigment and the shell is a physical change because it can go back to clay. Waste materials that are produced are the string that holded the paintballs alltogetter and smoke from the factorey from making the paintballs. some environmental consequences of porduction are with the leftover garbge it can get into rivers and into the forest and animals can eat them and that would cause the animals to die and the smoke from the factroey will get in the air and will cause us to breath it in.DISTRIBUTION. The paintballs get distributed by some guy or girl and they would have to drive a truck with them in it (some times a plan) to a big sports store where kids will buy it. The distribution of it is bad because it would have to go in a plan (some times) and then in a truck to the store and that would make a lot of air polushon.USE. A paintball lasts untill it hits soming hard or if not for a few years.DISPOSAL. A paintball is disposed of by it hiting soming and being left there. yes and no a paintballs can naturlly break down because sometimes it mite melt but it may not so ya yes and no. Paintballs can't be recycled because there not plasice, paper, cans and botles or boxes. Environmental consequences of disposal are if we don't stop with all the garbge then all that's going to be left of earth garbge. Paintballs are not susainable because if that bisnes digs for clay and pigment for years to come then there will be no more clayand pigment to make the shells and paint and without the shell and paint they can't make PAINTBALLS. = I learned about transfroming energy by experimenting. For example, we learned kenetec energy can become diffrent energys like wind energy. We made a sail boat that we had to blow on and the energy we created was turned into kenetec energy. So that's how and what I learned about transfroming energy. =
