1. What happens if the polar ice caps melt?
With all of the discussion of global warming, many researchers are looking into the events that would occur if the polar ice caps melted. If the polar ice caps melt there would be a rise in sea level. There would be warmer temperatures because there would be no "protection" so to speak, from the sun. There would be warmer water temperature which would change the flora and the existing sea life. Like a chain these elements would eventually lead to the demise of certain birds, fish, and would decrease food sources for animals that depend on them. There would be more diseases like Malaria and West Nile due to warmer waters and higher more humid land temperatures serving as breeding grounds or mosquitoes. There would be some vary detrimental effects, but these are highly unlikely. Here is a link for more information: http://www.nasa.gov/centers/goddard/news/topstory/2003/1023esuice.html
2. What other questions do you have about this science inquiry experiment?
What temperatures would be needed in order to melt the 25 million miles of thick polar ice? Also, isn't the temperature very cold in winter and mild in the summer, so much so that this melting not would not take place?

Reflection of STEM Strategies Week 2
Reflection 1: Planning a lesson using STEM strategies.
The usage of the 5 E's strategies were really helpful. The planning process was tedious to say the least. It made me look deeper into my teaching, planning, and practices. I found myself organizing the material differently. Throughout the planning I saw a need for the inquiry part of the lesson to be first. This is different than the usual way I would plan and teach. I like having the students conduct their experiments blindly so to speak. I believe that the idea of not knowing what will occur really engages the students in the activity. I wanted to incorporate more engaging material for the students as well as prepare them to meet the standards and the objectives that needed to be met.
If I were to implement this lesson I would allow the students to create the rubric for the assessment process. I realized that the students can and should be a major component of their own learning experiences.
