Combustion- Hypothesis: When we light the rubbing alcohol. it will give off polluting smokish-gas. What Happened: The alcohol inside of the bottle ignited and it blasted off with a whooshing sound and filled with fire.
Combustion causes climate change because it adds to the green house gases, causing the world to heat up.
CO2 Gas- Hypothesis: I think that this gas willl ignite. Well, it didn't ignite. It just put the fire out. This happened because the CO2 deprived the fire of oxygen, which is vital for a flame to burn. It is argued that CO2 in the ocean is being released because of evaporation and rising climates. And since CO2 is a green house gas, it is causing the climate to get hotter and hotter.
Hydrogen Gas- Hypothesis: I think that the Hydrogen will ignite like the first expiriment, because it is used as fuel. My hypothesis was curect, the H burned when fire was introduced.
Fossil fuel is declining so that instead of using one barrel of oil and getting a hundred, you use 50 barrels of oil, and only get 50 back. This is called net energy.
Ocean power has to do with the movement of waves going up and down, therefore creating electricity.
Biofuels are like fossil fuels, but it takes more fossil fuel to create energy equal to biofuels.
Solar electricity is one of the most popular sources of renewable energy. All of the power on the earth, solar power is the most common. Wind power is one of the fastest growing energy sectors. It is very efficient energy source.
Geothermal energy is energy created at the Earth's core.
Air Pressure-Hypothesis: The gas will turn to ice crystals. Well, nothing happened at all. Now we are going to do a second experiment. Hypothesis: The can is going to blast into the air when we place it in the ice water upside-down. That didn't happen either. Instead, the can kind of went *plink* and crushed into itself.

Changes In Children DNA
DNA Change In Children
Many children of liquedators that helped clean up the radiation have been shown to have various mutations. The most likely cause of this would be that they inherited some radiation from the parents, who received large amounts of radiation. These children are tested for these changes in DNA, the children's siblings who had been conceived before their parents' exposure served as internal controls, in addition to external controls from families who had not been exposed. There was a high count in DNA change, but we don't know if there are long teem effects of these DNA changes, but they have not been ruled out. But, as time went on, many of these changes Yet there armer many facts that put down this theory, including the amount of time in-between the exposure to radiation and the time of the conception. One of the ideas suggest that the cause of these mutations are of internal radiation. It shows a massive failure in the modelling of radiation risk by the International Commission on Radiological Protection. This is mostly from the atomic bomb that was dropped on Hiroshima, single massive bursts of gamma radiation delivered externally. But the ICRP studies are absolutely silent on the effects of internal radiation.
Questions:
1) Why are the children of liquedators(people the tried cleaning Chornobyl) having changes in their DNA?
2) How are they tested for DNA change? Or, to word it better, who is their DNA compared to?
3) What evidence is against this theory about DNA change?
