Gases and Climate Change

Combustion:
Hypothesis: If the flame touches the rubbing alcohol, then the alcohol will explode.
Observations: The alcohol was spread all around the bottle the flame was put in the bottle and it flew across the room. The flame and the alcohol must have opposing chemicals.

Fossil fuels, there is no doubt about it that they are polluting the air but are they causing climate change? I don't think so. We are harming the natural environment, we can do better.

Co2 gas
Hypothesis: If the carbon dioxide touches the flames, then the flame will grow bigger.
Observations: the carbon dioxide put out the flame. Fire needs to have oxygen to burn. Carbon dioxide takes out oxygen.

Due to deforestation, carbon dioxide isn't tran

Hydrogen gas:
Hypothesis: Its going to cause a minor explosion.
Observations: Once zinc was introduced to the hydrochloric acid, it started to bubble, and the fire was introduced to that product. The fire kept for awhile. Once the bubbling went down, so did the fire.

We took a look at some renewable energy sources including solar, wind, biofuels, and hydro power. Each year more and more people are using cleaner sources.

Air Pressure
Hypothesis: Once the can gets heated and it steams it will cool in the ice bucket and turn to water.
Observation: Nothing too exciting happened.
Hypothesis: If the can is heated then put upside down into the ice bucket, it will turn into water.
Observation: The can was crunched. You know how when your clothes get wet they stick to your body. I think its like that except with water vapor. The water vapor made the can stick to itself
