Science 10:  We started with an Intro to Nuclear Energy and a review of different types of Light Energy (TV waves, Radio waves, Microwaves, Infra-red, ROYGBIV colors (visible spectrum), UV, X-Rays, Gamma Rays).  After reading 10.1, we did pg 279 # 1-5 and 10-13.  In the second half we went to the Library and completed our last hour of research.

In your research, focus on the local and global impacts caused by the energy transformations that you are learning about.  Be sure to have a clear understanding of the energy transformations going on with your chosen topic.  Ask me if you do not understand the impacts, or do not know what information to research.  At the end of today's class  you were asked to share your notes document with Mr. Gale, like you did last day.  Next class we will figure out how to report the information.


Chemistry 12:  U4 # 1-14 due Monday.  Test on Solubility on Friday, the same day the Practice Test is due.

Science 10:  Today is the first of 2 hours of research dedicated to learning about the impacts of Energy Transformations from Technologies.  Your task is described below:

Show that you know some local and global impacts of energy transformations from technologies.

Topics you could learn about:   hydro electric dams, wind farms, biofuel production, natural gas production, power grids, fossil fuel pipelines, solar generating stations, coal fired electricity generation, geothermal heating, world food production, liquid fossil fuels, glaciers and ice sheets, nuclear electrical stations, Columbia River Treaty, Tesla, fuel cells... ask me if you are interested in some other energy-related topic.  

Impacts could be on the land, water or air in the area (or further away) where the energy is extracted, processed, or used.  The impacts could also be on the people or other organisms that live near these places.  Since Global Warming is the main environmental threat of our time, be sure to explain the role your topic plays in Global Warming.  Be specific about the places you are learning about.  Local is nice, but non-local is ok too.  

Today is a learning day only.  Take notes in a new Word Document to record your learning. Make a list of websites that you are using as sources.  Save this Word document to your One Drive using a descriptive file name.  Later we will find a way for you to present your information.
