Solid Waste Waste Disposal
2,006 wordsWhen I was a child, recycling was only important at school. My teachers would always tell me that recycling was good for the earth. But, I didn't really show any concern, because my parents never really mentioned recycling until I got older. I started recycling aluminum cans, because I found out that companies paid money for recycled cans. The first time I took my cans to be recycled I got forty dollars, so naturally it became a regular hobby of mine. Not only did the money impress me, but also ...

Liquid Fueled Rockets Liquid Fueled Rocket Fuel
901 wordsA rocket is a device that does not need atmospheric oxygen to burn its fuel, since it carries its own, either separately or in chemical combination with fuel. Rockets are propelled forward by gas or liquid being expelled backwards. Rockets work on a fundamental law of motion by Sir Isaac Newton that states, for every action there is an equal and opposite reaction. This helps explain how rockets fly on earth and in space. For example, the rocket fuel is exploded in a controlled way so that the ex...

Circle Cannot Exist Shape Cannot Exist Definition
1,433 wordster>"Shape is that which alone of existing things always follows color. "A shape is that which limits a solid; in a word, a shape is the limit of a solid.
