Reviewer Comments:

This is an engaging, safe activity for kids to explore exothermic reactions using inexpensive materials. Overall, the resource would benefit from some teacher background information, as well as an answer key for existing prompts.

Here is an article I found helpful with more background on how these work: http://www.scienceiq.com/facts/warmerhands.cfm Also, just for "fun," here is a study concludes that EATING one will not cause you any serious toxicity! http://www.ncbi.nlm.nih.gov/pubmed/18787994 (I wonder why four elderly patients ingested the contents of hand warmers in the first place...)
