Second Edition Updates

Posted by Antonio Chaves on Friday, September 26, 2014, In : new lab procedure 
The second edition is finished. I have updated the lab manual page to reflect this, and changed the posted excerpts to incorporate the final corrections. To save printing costs I have removed the last activity from the printed book and put it into the CD as a "supplement" because it has many pages, and is too difficult for most environmental science students. I like this activity (Chemistry of Flue Gas Desulfurization), but to be honest I only used this activity on my AP chemistry students. I...

Electric Scooter with Battery You Can Charge In Your House

Posted by Antonio Chaves on Saturday, September 20, 2014,
One of the biggest disadvantages of electric vehicles is access to charging stations. People who own houses can have charging stations installed on their property, but what about those who live in apartments?

Posted by Antonio Chaves on Monday, September 8, 2014, In : environmental news 
Do not forget to recycle those batteries! This photoshop gives you perspective on how much target material you get out of mines. One of the biggest problems with the mining of metal ores is that the environmental costs are not incorporated into the monetary cost of the product. Consequently, taxpayers usually take up the tab for remediation of the toxic residues from the ores of nickel and copper, not to mention the ripped up landscape (I do not know if this is also true of diamond mines). In...

Presenting at the Maryland Association of Science Teacher's Conference

Posted by Antonio Chaves on Saturday, September 6, 2014, In : lab procedure explanations 
I will be presenting one of my lab activities at a conference for the Maryland Association of Science Teachers (MAST). My presentation will be on Saturday, October 18 from 9:30-10:30 AM. In addition to presenting, I will also be at a table where I will be selling copies of the newest edition of the lab manual. Since this table space will be much more than I need, I will use most of this space to do demonstrations that will hopefully get people's attention.

Publication Delay

Posted by Antonio Chaves on Thursday, September 4, 2014,
My deepest apologies to those who were expecting to have the a copy of the second edition at the start of the academic semester. Due to some unexpected issues I will need a few more weeks. It will be up for sale by the end of September.

About this blog

This blog was originally created in January 2013 to serve as a means for providing updates on science activities from the environmental science lab manual Ecology, Development, and Sustainability. I have now expanded its purpose to include other items of interest to science teachers.
