i have made the layout for the game board that i want to make

the objective of the game is to let people know and understand the consequence of global warming and teach them how to prevent global warming

i have guided my team and told them what to do and have decided on what product to make

Reflection (9/2/10)

Today, Wen Kai and me did some research on greenhouse gases, effects of it and how it happens.

This is what we found:

The greenhouse effect is caused by an atmosphere containing gases and emitting infrared radiation. However, the earth is currently suffering from greenhouse radiation, because human machinery has been producing a lot of atmospheric gases. The main four gases contributing to enhanced greenhouse radiation are water vapour(36-70%), carbon dioxide(9-26%), methane(4-9%) and the ozone(3-7%) gases.

When the sun shines on earth, about 50% of the heat energy is trapped by the atmosphere. The more humans contribute to greenhouse gases, the more heat is trapped. The more heat is trapped, the higher the average temperature of the earth. The higher the temperature of the earth, the easier the icebergs melt. And like in what was said last week, once the ice melts, the water level will increase, causing flash floods.

What humans mainly contribute to the greenhouse effect is the carbon dioxide gas. We all breathe in oxygen and give out carbon dioxide. Usually, trees performing photosynthesis will be able to counteract the carbon dioxide gases. However, with deforestation and the burning of fossil fuels, there are now less trees to counteract the increase in carbon dioxide. Fossil fuel burning only add on to the carbon dioxide. Carbon dioxide is an atmospheric gas, it will absorb and emit more and more thermal infrared. To help reduce the rate of the Earth's temperature increase, we can switch to more eco-friendly alternatives of lifestyle, like using less charcoal,fossil fuels and paper.

I have completed the worksheet and have a basic understanding on how to start the project

today, we basically compeleted the worksheet passed to us. I did a bit more research into global warming, espically the melting polar ice.

Reflection 3/2/10

Today we did our research on causes and effects of global warming. As we know, we would not want to be in a period where global warming is affecting us. What we can do is to find out what and why it is affecting is and try to help. We found that if global warming is not being controlled, the polar ice caps would melt, increasing the level of the ocean. Consequences are that coastal cities would be flooded and more oceanic disasters would happen. There would also be higher frequency of water-born diseases like Malaria, Dengue and West Nile virus.

Melting Ice

According to most research, over the past 100 years, there has been a half degree of temperature increase in the earth's average temperature. This may sound like nothing, but every degree has a adverse effect on our earth's temperature. The subject todays is melting polar caps.

Basically the polar ice float by displacing large amounts of water. However, with the increase in temperature, the ice are falling into the ocean and when the ice falls, it displaces a certain amount of water and increase the water height.

Though the ice caps are the seemingly most likely to melt, that is not true. Greenland is more a possibility. If it melts, it would add 7 metres to the sea level.

Scientists predict that by 2100, sea levels would rise by a max of 20 inches, and this would have a major impact on coastal cities.
