Actions that impact energy

Dave Wilms, former Stevenson HS teacher and current energy consultant, visited our 4th grade for the third time this year.  He has been exploring the concepts of energy efficiency, conservation, and the impact on our environment.  What is the difference between energy conservation and energy efficiency?  I will give you a hint.  One has to do with behavioral changes and one has to do with technological advances.

These classroom visits were scheduled to augment a recent unit of study.  As you may have heard, we have been replacing our old science units and aligning our curriculum to the Next Generation Science Standards.  Here is a link to the 4th grade standards.  We are grateful for the leadership of Kery Obradovich, Math/Science Coordinator and Kristin Cioffi, Math/Science Coordinator.

The students explored common items and how much energy could be saved by recycling.  Did you know that it costs less to recycle than to pay for garbage removal?  Only a small amount of things need to go to the dump.  Most city waste is paper (27%).  The second biggest item is food (14%).  Yard trimmings (14%) is third.

Our students were able to “describe that energy and fuels are derived from natural resources and their uses affect the environment”.  They were able to “generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans”.  Having observed the student discussion today, I am confident these students will grow up to solve the energy problems of today and tomorrow.
