Subject-Mr. Ekinci
H: Hello Mr Ekinci.
E: Hello Homer.
H: What is physics to you?
E: Physics is the study of matter and the way it moves in space. It can be found all around us, everywhere we look. Physics is life.
H: What made you want to become a physics teacher.
E: Well like many other people who have become scientist, I was fascinated by the world around me. I became a physics teacher so that I could better understand how it works.
H: When you see smoke, does it usually rise or fall?
E: It rises Homer. Give me a real question.
H: So why is it that when my paper is burned into my container, the smoke falls?
E: Well, when we see smoke, we usually see it rising out in the open, but when burned in an airtight container, it will fall.
H: Why is that?
E: In the open air, there is oxygen, which is a heavier gas than carbon dioxide (smoke). In the open the oxygen sinks down and pushes up the carbon dioxide. When put inside of an air tight container, there is no oxygen. By default, this makes the carbon dioxide the lightest gas in the room. With no other gas to push it up, it sinks inside of the container.
H: How does my project relate to physics?
E: Well we are looking at how the mass of the gas moves through space and how gravity effects it's motion.
H: Thank you Mr. Ekinci.
E: Anytime Homer.
