A) What happens if he polar ice caps melt?
Based from the following website, http://www.nrdc.org/globalwarming/qthinice.asp,
the polar ice caps are already melting quickly and affecting the lives of those living in the arctic.  This is also having a huge affect on plants and animals of the region as well.  With the ice caps melting, land, people, animals, plants, and other things will be affected.  However, scientists project only a 3 foot rise in sea level by 2100.  For us, this is a long time away! For our children's children, this might become more of an issue! Over a long period of time, sea levels will rise. The more they rise, the more potential for a major disaster. 
B) What other questions do you have about this science inquiry experience?
What grade level would this experiment align with?
