“Mystery Matter Magic Show”
Teacher Demo #1– “Rising Water!”
1. What happened to the candle when the glass was placed over it?
2. What happened to the water level inside the spirit glass as soon as the candle flame went out?
3. Why did the water rise inside the spirit glass?
4. Which air was stronger? The air outside the glass or the air inside the glass?
Teacher Demo #2 “The Collapsing Aluminum Can!”
1. What happened to the small amount of water, when it was placed on heat?
2. When the water began to boil, did the liquid change phase? If so, what did it change into? What is NOW filling the inside of the aluminum can?
3. What did I do, abruptly, to the water vapor (gas) inside the aluminum can when I flipped it over and placed it in the ice water?
4. Cooling the can, caused the water vapor (gas) to undergo what change in state of matter? What do we call this process?
