Crushed Can Observations.

Nancy- ~There is a snapple can on a hot Plate.
~There is a beaker with ice water in it.
~The teacher quickly flipped the hot can into the ice water.

Hannah-
- There is a Snapple can on the hot plate.
- The hot plate made the Snapple can very hot. We could see steam coming out of the can.
- There is a beaker (one liter) filled with ice cubes and water.
- When the Snapple can was taken off the hot plate and put into the the beaker, the can imploded.
- We used tongs to put the can into the beaker.

Today we were reasearching a problem. Why do clay boats float? Mrs. Laguna told us to look something up and I went on to googe.com and I typed in the question "why do boats float?" and I found this link
http://www.koerger.com/Assignments/Science/07-08/26_%207.3%20-%20Clay%20Boats.pdf
This the same lab that another class did.



Hypothesis-
The shape and the amount of air in the boat will make the boat float.


Independent Variable-

Dependent Variable-

Solid- Dodgers becuase they were okay untill they got to the playoffs. The state in which matter has a definite state.
Liquid- Nationals becuase they did a little bit better than the Dodgers.
Gas- Rays because they are losing but they made it pretty far in the playoffs.
Plasma- Phillies becuase they are winning the most games so far in the playoffs.

Our group predicted that the temperature would go down when we fan the thermometer.
Once we conducted the lab, we found out that the tempature does not go down.
In fact, the tempature barely changes! All the fan does is move the air around.
Our hypothesis was wrong.




Here is a table of our data:

1. We all think that there are deatiled pictures and how they talked clearly.
3. I liked the changine pictures and they talk clearly.
4. I like how the informative it was and how there was one person saying the question and they other person would say the answer.

Three Things We Learned From the Movie.
1. When a book falls off the table, it has kenetic energy.
2. When a book is picked up and put on a table, potential energy was used.
3. When a book falls off the table on your foot, it has kenetic energy.

Today was our last day of this expiramant. Our Beaker with water and test tubes did not change at all within the five days.
Our results were for the steel wool it was consistantly 200 mL and the control was 60mL.
