Bronx Global Learning Institute for Girls  

                                     WELCOME TO OUR SCIENCE COMMUNITY

BGLIG Students and Staff,

I would like to welcome all 6th, 7th and 8th grade student to our Science School Community blog. This is going to be an exciting year in science and the science blog is just one of the many tools we will have to help us understand the nature of science and how scientist think.  I will be posting every Sunday our weekly science topics and activities.  Please be sure to visit this site regularly and read the information posted.  Also, students can leave comments/questions related to assigned classwork, homework,  or just blog any scientific observation or concerns,

Also, you will find helpful information here to help you understand and complete classwork, homework, projects, study for test, complete end of the year science project and prepare for the following lessons.

Science Activity 1:  Week September 11 - 15, 2017




                                            Melting Icebergs: Science Inquiry Activity

The presented melting iceberg experiment is a great activity to present students with an inquiry of the effects of such events.  This task is structured and contains the necessary guidance as to permit students construct and formulate their own questions as to understand the reality and seriousness of the melting of icebergs and the polar ice caps.

The experiment demonstrates that as the floating ice melts the volume of water increases.  What would happen if the polar ice caps melted? There will be a combination of events: 1) rising sea levels, 2) accelerate global warming, 3) changes ecosystems, 4) threatens human culture and economics, and 5) increases seawater freshwater contamination, which can effect coastal erosion.  All these in one way or the other are interconnected.

One of the most talked about concerns is that of the rising of the sea levels.  It has been documented that the melting itself of icebergs doesn't affect sea levels.  On the other end, the melting of the polar ice caps will because as the ice melts, the temperature of the seawater increases.  It is important to mention that the polar ice caps help reflect sunlight back into the atmosphere; if the ice is melted the sunlight (heat) will be absorbed by the ocean thus increasing its temperature which will case the water to expand an rise.  The rising of the temperature will accelerate global warming.

Global warming has been a topic of national an global importance among communities of scientists an political officials.  This itself can bring other questions (inquires) from this activity:

A.  How does global warming affect the polar ice caps?
B.  Have governmental agencies develop a realistic plan to slow own global warming?
     * In the last 100 years global warming has increased 1/2 degree
C.  Currently, are the 2 mayor polar ice caps in danger? (Artic & Antarctica)
D.  How will it directly affect populations of humans and other species?

All these questions can have its instructional value during this activity.  The great part of these types of activities is that it invites students to formulate their own inquiries and look for answers.  Definitely, this is an excellent activity using inquiry base instruction in which active learning is in place.  Students will engage in the activity by formulating questions and collecting data, which they will use to present and reflect on.  Students will conduct the experiment and apply their learning to their lives and society (Hammerman, 2006).
