Melting Icebergs Experiment

This week's assignment opens my eyes to the effects of global warming and its issues.  Likewise, this experiment will bring awareness to students about global warming.  In this experiment, we create our own icebergs using ice cubes.  After lumping ice cubes together in a bowl the night before per instructions, I let them freeze overnight.  The next day, I place the lump of ice cubes into a bowl.  Then, I pour water in the bowl until it reaches the top without overflowing.  The next step is to form a hypothesis and observe what takes place.  My hypothesis is that the melting ice produces excess water in the bowl that will eventually cause an overflow of water from the bowl.  From what I observed, some of the ice was extending beyond the top of the water.  As time elapsed, I witnessed water overflow from bowl.  However, only a small amount of water overflowed.  Afterwards, we are to respond to question number nine.     

9. Extended Questions
 
a. What happens if the polar ice caps melt?
The melting of the ice caps will affect on humans, wildlife, sea levels, and global temperatures.  The affect on humans will be unstable weather patterns that threaten lives, cause damage to structures, and food supply shortages.  Wildlife will experience extinction of some species, loss of habitats, and loss of food supply.  The increase in sea levels  can result in destructive flooding.  While the loss of glaciers and sea ice along with pollution contributes to the rise in the planet's temperature which affects the Earth's climate.  

b. What other questions do you have about this Science Inquiry Experience?
How will global warming and disasters affect how we erect buildings such as houses, schools, shopping malls, grocery stores, warehouses, civic centers, and government facilities?
How will humans and wildlife adapt to the changes brought about by global warming?
What changes in species will take place as a result of adapting to new environments?

Reflection: STEM Strategies Lesson Plan

Reflection: Lesson Plan

Hello Fellow Bloggers,
Welcome.  I am looking forward to a sharing my teaching experiences and graduate school experiences with you.  To recap, I am a Certified Science teacher in Georgia.  It is a joy to teach science and work with middle school students in a science classroom.  Obviously, I hope my passion for science will spread to my students and they will share the same enthusiasm for learning as I do.  
On the other hand, I want to reflect on this week's application.  Our assignment was to use a Science Lesson Template to plan a lesson that centered around Science, Technology, Engineering, and Math (STEM) strategies for diverse learners.  We were given the 5 E's Strategy to assist us in this process. 
The following will explain the terminology:
Engage - Hook
Explore - Experiment
Eplain - Introduce New Material
Elaborate - Real World Connections
Evaluate - Assessment
Candidly speaking, it was an extremely frustrating and overwhelming at times planning this lesson using this new strategy.  I really could have used a face to face group meeting or an exemplar.  This assignment would have made an excellent cooperative learning experience.  Consequently, I did not feel confident that I had completed the Science Lesson Template correctly.  After another colleagues, and viewing questions that were posted on Q&A I gathered I was not alone.  It seemed that with all the planning I did for the lesson plan, the template and the plan just were not a match.  
Time was a factor in completing this application.  Time is valuable not only to a teacher, but in general.  Time would be a factor trying to perform this lesson in a classroom given some classes are not an hour long.  There were some parts that seemed redundant. Although, there were sections that were helpful.  I can see where the historical perspectives and real-world context could be a challenge in come cases.  Just like our students, on some assignments, I think we need that constant feedback and collaboration that comes from being in a group or in pairs.
