    My topic is about the melting of the polar ice caps. Carbon Dioxide is a huge contributor of the ice caps melting. When Carbon Dioxide is emitted into the atmosphere it builds up a layer, therefore when the sun heats up the Earth it's also effects the layer making the Earth twice as warm. Since the Earth is getting warmer, the ice caps are melting. As the ice caps start to melt at a rapid rate it effects the Arctic land animals such as Polar bears. With only a few ice sheets spread out, it's hard for animals like Polar bears because they aren't able to swim incessantly for hours on end. In the end this will make the Polar bear and other Arctic land animal population dramatically decease, possibly become extinct. By doing this topic I learned some of the 7th grade life science learning goals. Part of the "Earth and Life History (Earth Science)" I learned how the Earth is heated by the sun and how it effects the ecosystem.
Important Vocabulary Words:

• Glacier: an extended mass of ice formed from snow falling and accumulating over the years and moving very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation. 
• Iceberg: a large floating mass of ice, detached from a glacier and carried out to sea.
• The Ice Age: An Ice Age is a period of geologic time in which the Earth's climate sees a dramatic drop in temperature. The drop often is followed by larger ice fields in the polar regions. 
• Polar Ice Caps: A polar ice cap is a latitude region of a planet or natural satellite that is covered in ice.
• Sea Level: Is a measure of the average height of the ocean's surface (such as the half way point between the mean high tide and the mean low tide)
• IPPC: Intergovernmental Panel on Climate Change
• EPA: Environmental Protection Agency 
• Global Warming: an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect.
• Greenhouse Gases:  any of the gases whose absorption of solar radiation is responsiblefor the greenhouse effect, including carbon dioxide, methane,ozone, and the fluorocarbons.
• Carbon Dioxide: a colorless, odorless, incombustible gas, CO ₂ , present in the atmosphere and formed during respiration, usually obtained fromcoal, coke, or natural gas by combustion, from carbohydrates by fermentation, by reaction of acid with limestone or other carbonates, or naturally from springs.
