Gasses and climate change

Combustion
Hypothesis: The combustion will produce flame and soot but nothing else.
The combustion created a sound like a whoosh and flames flew into and out of the bottle.
The human race is creating chemicals that a not supposed to be int eh atmosphere by using combustion.

CO2
Hypothesis: The flame will create a sound and soot.
The CO2 killed the flame.


Hydrogen
Hypothesis: There will be no flame.
The chemical reaction from Zinc and the acid was fizzy.
The flame created a boom and a flame that eventually dissipated and bubbled the liquid.
There are many fuel sources that the humans do not use like tidal power and geothermal energy, these are powerful and could work as renewable resources, also scientists believe that in 2025 the world will be at Peak Oil which means that almost half of the Earth's oil that can be extracted will be extracted.


Air Pressure
Hypothesis: When she puts the can into the ice bath, the can and vapor will freeze because of the change in air pressure.
When she put the can into the ice bath nothing special happened.
Hypothesis 2: When she puts the can that is sideways is the vapor will turn to ice.
The rapid change in air pressure crushed the can. The inverted can also took in some water and replaced the vapor in the can.
The air pressure is changing and affecting temperatures and other weather like increases of rain in Scotland, reduced rain in Spain, and a drop in the number of cold snaps in France.
Winters will be warmer, wetter, and windier in Europe due to changes in air pressure.
The winters will get milder in Canada and the U.S.

Chornobyl questions

1) Why did they have to do the tests?
2) Why were the scientists not informed that the reactor was unstable at the time?
3) Why was this not prevented?
4) Why was this not prevented?
5) Why did they put soldiers at risk after the explosion by putting them on guards?

Panel Questions

1) What has been done to stop the chemicals from leaking into our water like they did in the 50's?
2) What measures have been taken to stop the spread of the chemicals today?
3) Is there proof supporting your viewpoint?
4) What exactly did the Superfund project do to prevent animals from coming in contact with the chemicals?
5) Is there proof that there are still toxins in the canal?

8-30-10 catalyst

1) The blizzard of '77 along with the early spring and melting. This caused the overflow of water and toxic chemicals to then rise to the surface of the first cap that was installed by Hooker chemical.

2) Most of the chemicals dumped there were linked to cancer. There were also birth defects and miscarriages.

3) The underground animals like moles and groundhogs can die by going to this place. The predatory animals were also hurt because if they ate things like moles they could die because of no food in the area.

Hazards of oil dispersants

I found that the oil underwater will probably resurface later. I also read that there're underwater plumes of oil coming out of the well. Solving one problem will create more problems. This is because now we are putting chemicals into the water that kill animals. The chemical dispersants are worse than the oil because toxicity to humans and fish is enormous. Oil cannot injure you like the

8th Grade DLC reflection

1. How much harm can the chemicals cause to the human population.

2. How badly can we injure the animals?

3. Why is BP using these chemicals?
