Gases and Climate Change.

KA-BOOM!

1. Combustion. Hypo: If a rubbing alcohol is ignited by flame, then the alcohol will explode, because the alcohol will combust when ignited by flame. BOTTLE ROCKET!!!! The alcohol ignited and shot in the opposite direction of the cap hole where the lighter with flame was placed. KA-BOOM!

2. CO2 Gas. If CO2 is introduced do the flame, then the flame will go out. The CO2 and the flames were extinguished. Fire needs oxygen to survive, and too much CO2 can extinguish a flame.

3. Hydrogen Gas. If the Hydrogen gas is exposed to open flame, the gas will combust and explode. IT GO KA-BOOM!!! The flame was introduced to the hydrogen gas and the gas exploded and then burned for probably ten seconds.

4. Air Pressure. If the can with gas is placed into the Ice water, then the gas will cool and nothing will happen. Nothing happened. Boo hoo.
If the vapor goes in facedown then it shall go boom. The can imploded. It folded into itself like a black hole thing in star trek.

Greenhouse Stuff. The slideshow presented facts about climate change the effects that human activity had on the environment and the rising temperature of the Earth's atmosphere.

CO2 Emission Article. The article spoke on the topic of Carbon Dioxide emissions and that there are many different ways of releasing it to the atmosphere. Cutting down trees and burning fossil fuels are two of many ways to release carbon dioxide. The CO2 Gas traps some of the heat that should be released back into space and keeps it in Earth's atmosphere. The Earth will become steadily hotter and hotter because of these emissions.

Renewable Sources: Wind. 20% of the electricity of the world is powered by wind. Although it is a great energy source, the wind is not reliable because there is not always wind, and most buildings have to have some sort of other electricity source so that power will always be present in that building. Geothermal. The Earth's core is 4000 degrees Celsius. Some electricity companies have found out how to harness this heat and use it to produce energy.

Lingering Effects

BBC wrote an article concerning the fact that there're were lingering effect of the radioactivity in the Chernobyl area. Fish in norway and Cumbria showed surprisingly high amounts of caseim 37. Even 14 years after the explosion, cesium is completely immoblished, but can be re-released to the ecosystem. Forest berries, fungi and fish frm parts for another half-century. Certain restrictions food may be needed for 10 to 15 more years, 100 times longer than originally planned. The environmen isn't cleaning itself.

1. What DNA Is being affected?
2. Is any of the DNA that is being altered fatal?
3. What can be done to fix the malformities?
