Ju Young – Arctic Ice Investigation ****************************************************************************************** Research Question:
How do greenhouse gas emissions give an impact to the Arctic sea ice?
1. A statement that predicts what will happen. Use the structure: ‘If…then…because…’ 2. For the ‘because’ part you need to give scientific reasoning so after you have done your research, state in parentheses ( ) the author of the source that helped you decide on your hypothesis. [Remember to write the full source at the end in the Works Cited list.]
My prediction is that the Artic Ice will change state into water much more rapidly. This is because the world’s emissions of greenhouse gases are increasing especially C02, which gives a big impact to the world climate to change. Since C02 is a greenhouse gas this means that when C02 exits the atmosphere some of it reflects back to earth, this changes the temperature inside the earth. The cause of this problem is that us humans produce to many gases. For example, we use factories, cars, burning coal and have a major use of oil production, which releases methane, C02, nitrous oxide etc. Which warms our atmosphere that acts like a blanket. Since the world is getting developed we will need more productions of fossil fuels, factories, electricity etc. it will release more greenhouse gases into the earth’s environment. Therefore, the Arctic ice will melt because of the increase of atmospheric C02. Furthermore, animals that live in cold climates can get extinct from our world. Such as polar bears, penguins, whales etc.
Observations and Raw Data:
1. Present observations in a logically designed table that is easy to read. 2. Give each table a detailed title that includes the independent variable and the dependent variable. 3. Each column heading should contain the name of the quantity being measured and the units of measurement.
Raw results Table:
20 years time period
Carbon Dioxide produced in ppm (IV)
Extent of Arctic Sea Ice in million km² (DV)
Analysis: (See page 2)
The graph shows a decreasing trend in the extent of the Arctic sea ice. Because as more Carbon Dioxide and other greenhouse gases are produced the Arctic’s sea ice will start reducing rapidly.
The range between of how much C02 is produced during 1980 and 2000 is 31.03 ppm (It is a 20 years period)
The biggest change during 1 year is 1997 and 1998 which is 2.73 ppm
Arctic sea Ice altitudes increase sometimes because of some strong winters. However, now there is more atmospheric C02 since our world is more industrial, which will decrease the amount of strong winters.
Carbon Dioxide can’t be destroyed, however this atmospheric gas has a long life span so it will take about 50-200 years. In the raw data and graph C02 levels are rising much more quickly than before.
Carbon Dioxide can only be increased. The amount of Carbon Dioxide can never be reduced. (If you wanted to wait for 500 years)
Processing and Presenting Data:
1. The graph needs to be a scatter plot with a trend line.
2. Put the independent variable on the x-axis, put the dependent variable on the y-axis. 3. Label each axis with a quantity and a unit.
4. Give the graph a detailed title that includes the independent variable and the dependent variable. 5. Take a screen shot of the graph and paste it here.
1. Summarize in one sentence whether or not the changes of the two share a pattern 2. Point out any strange...
