Gases and Climate Change

1) Combustion

Hypothesis: If Rubbing Alcohol is ignited by fire inside of a plastic two liter bottle, the rubbing alcohol will turn to a gas and the vapor will rise from the bottle.

Results: When the bottle was set on it's side and the flame was put to the open lid once all of the excess rubbing alcohol was removed, the bottle set a large spark and flew back in the direction that the bottom of the bottle was faced. There was also a loud whoosh sound as the bottle flew very quickly.

The slideshow animation was very hands on and really showed you what types of gases were where in the environment. It seems as if many of the same gases humans use animals use as well, but to a much larger extent.

2) CO2 Gas
Hypothesis: If the flame on the candles are exposed to the gas caused by the vinegar and baking soda, the flame will grow to be larger in a very fast manner, and then quickly retreat to stop burning.

Results:When the gas was exposed to the flame, both of the candles stopped burning as if they were blown out. Since fire needs oxygen to burn, and the carbon dioxide was exposed to the flame, it was blown out because the fire was deprived of oxygen.

It seems to me that people are removing too many plants that would normally be converting CO2 to keep the balance but since,

3) Hydrogen Gas
Hypothesis: If the Hydrogen is being separated from the HCI and then the Hydrogen gas is exposed to flame, the flame will remain burning.

Results:My hypothesis was supported in the aspect that the flame kept burning. The fire remained as long as the gas that was being produced was still present. Due to the results of this demonstration I would believe that using Hydrogen would be a great source of power due to how clean it burns.

4) Air Pressure

Hypothesis 1: If the heated can of a little bit of water is but in a bowl of ice water bottoms down, then the gas that was created by the heating will quickly release from the top of the can.

Results 1: When the can was put in the ice water, nothing happened. Perhaps too much of the vapor was already released, or the water wasn't hot enough.

Hypothesis 2:If the heated can of a little bit of water is but in a bowl of ice water up-side-down, then the gas that was created will cause a sizzling sound and the air will release into the water and bubbles will rise.

Results 2:When the can was put in the ice water up-side-down, the can imploded with a large crackling sound as if it were crushed because the air had nowhere to escape. Since chemicals take up more area then when they are in a gas form, when the water was turned back into a liquid the space it took was not being used and the air pressure caused the sides of the can to fall into itself to fill the vacuum.

Our Climate Response:

Between the two forms of Ocean Power, I think that the use of Tidal Power is much more practical then that of Wave Power due to the predictability levels. An unpredictable source of energy should not be depended on to supply power. Biofuels seem to not be useful very useful because it takes so much money to turn it to a useable form of energy, that it almost even outs with the amount it supplies.

Chernobyl Children Show DNA Change

I agree that just because the effects are happening now does not mean it will not affect the future. If there are DNA changes occurring in the current generation only means the more likely it will affect later generations through their parent's genes, and not just fade away into obscurity. Even very low doses of radiation can still make changes in a person's DNA. When a child is still inside of it's mother it is especially vulnerable to the harms of radiation because it is still developing. Many of the children that were effected from this radiation had a parent, or parents, that were liquidators. “Liquidators” were people who helped clean up the aftermath of Chernobyl. These children were exposed to it much more then other children through their parents. Their parents were not effected as strongly because they were fully developed at the time and their bodies could handle the radiation.
