The Law of Conservation of Mass simply states that matter cannot be created or destroyed in a chemical reaction.  What goes in must equal what comes out.  I went on a search to find images to support this scientific law.  The top contenders are shown below.

The stats that John Medina put out there in Brain Rules were quite interesting.   The idea that recognition and recall soar when text, the oral word and  images are used effectively was worth the read.   In fact I really like the visual presentation of his ideas.  Much of his ideas seem related to the work of Gini Rojas, an ESL specialist that just visited our school.  She gave a variety of examples of vocabulary teaching strategies that had us do something with the words.  Text alone was not enough.

Unfortunately, I really don’t think the images I found bring that much depth to the fairly clinical topic of conservation of mass.

New Search: Chemical Bonding

Ionic bonds occur when electrons are transferred thus positively and negatively charged ions are attracted to each other.  It’s all about attraction!

Covalent bonds occur when atoms share electrons.

This seems to be getting a bit deeper.  I think I’ll try using these to help students prepare for an upcoming assessment.  They could compare/contrast/review the two types of bonding using these two images as cues.  Can’t wait to see what happens.  Ha!
