Combustion
Hypothesis: I think a small blue flame the size of your thumb will shoot out the top of the bottle. I Then think you will see a small portion of soot around the rim and laying next to the bottle but not much.
What really happened: A huge flame came out the top and the rocket shot straight across the room in a huge blue flame.
The site we read was about how combustion effects the world and what chemicals are interacted with it, such as H2O.
CO2 gas
Hypothesis: I think that the CO2 will cause a small explosion type thing simalar to the last demo and might cause a small flame to appear at the top.
What really happened: The CO2 gases caused the flame to be put out because the flame needs oxegon to live.
Hydrogen Gas
Hypothesis: I think the flame will be constant for about 10 seconds then it will go out as the gas expands.
What really happened: The beaker let off a big smoke and when the flame was intereacted with it the flame made a loud pop and the gas sizzled and popped while on fire for about 20 sec till the gas
Air pressure
Hypothesis: I think the can will be squished as if a person is smashing it between there hands and the vapor will come shooting out the top.
What really happened: E first time with can facing up nothing happened. The second time with the can facing down the can sucked itself in and it need up smashed.

5 Chernobyl questions...
1. How are the lifeforms, andimals, plants, etc. living in Chernobyl when other towns are impacted in such ways like Sweden and Norway who had to carry off the bodies of dead animals that had eaten infected grass?
2. Why is Chernobyl suitable for life and places like Sweden and norway, they had to remove lots of dead lifeforms because they had eaten contaminated soil?
3. If other bombing such as Hiroshima were hundreds of time more powerful why did only 87 people die when the thousands at the bombings die.
4. "One corner of a field might be highly dangerous, while just a few yards away levels seemed low." What caused this to be that way?
5. Why did Thyroid cancer increase so much after Chernobyl?

5 questions
1. What about the chemicals in the river what happened to those?
2. What will happen if another blizzard backed up with a early spring shows up in the next few years?
3. Has anyone gotten sick from some sort of chemicals in the last 30 years?
4. How close are people living to the canal?
5. What will happen in the event of a natural disaster?
2. What will happen if another blizzard backed up with a early spring shows up in the next few years?
3. Has anyone gotten sick from some sort of chemicals in the last 30 years?
4. How close are people living to the canal?
5. What will happen in the event of a natural disaster?
Catalyst
1. The blizzard in 1977 caused the love canal to overflow and when it overflowed the chemicals were pushed up through the ground.
2. Some of the hazards were cancer, liver problems, and birth defects.
3. The fish in other creeks Darby that had chemicals leaked into may have been harmed by it as a well as animals that depend on that water to live.

Hazzards of oil dispersants
After reading the article and watching the video we learned that BP is using a chemical called corexit to dissovle and break down the oil through the water. The articles said that BP claimed 26% of the oil is left are tarballs were sheen. We also learned that some of the long term effects on marine life are the existing tar balls sinking to the bottom of the ocean and polluting the sea floor and sea floor marine life such as crabs and lobsters. Also there is some of the tar balls washing up on shore polluting the beaches.
