Materials, trash and recycling
When we recycle we just throw stuff into a bin and it gets taken away. We don't have to worry about how it gets seperated. We usually recycle metal and paper. One of the most effective ways they sort everything that gets recycles are magnets. At the facility they have a conveyor belt that moves everything down and at the end they have a magnet that will pull all the metals up and than a fan will blow the cans to a separate area. The reason this works is because of the electrons in the atoms. The electrons are able to move freely between the atoms which makes them magnetic. The easiest metal to recycle is aluminum because it is a pure substance with no chemical bonds so when it is melted nothing is broken.
For as long as I can remember I have been putting a blue trash can at the end of my driveway every wednesday. I have always thought to myself I am doing a good thing by recycling this soda can or water bottle. For example, steel cans are one of the most recycled items. For every ton of steel that is recycled we save 2,500 pounds of coal, 1,400 pounds of iron, and 250 pounds of limestone. This means we don't mine and burn coal which is really good for the environment. Purchasing recycled metals are usually cheaper because they save a lot of energy which is better for the community and the environment. Recycling also keeps materials that don't biodegrade out of the oceans and the streets.
One of my biggest takeaways from this project and background knowledge we learned about before were all the types of bonding. Everything we can see and touch has an ionic, metallic or molecular bond. I understand how to read and look at the periodic table and figure out why it is organized the way it is.
