I was recently reading the November/December 2022 issue of “Science & Children” a publication of the National Science Teaching Association.  In this issue, I read the “Methods and Strategies” column, written by Christopher Roemmele, Steven Smith, Sarah Nern, Brett Criswell, and Miss Holzer.  They wrote an article entitled, “Don’t Forget the Demo.”  

Demonstrations are defined as the manipulation of materials and equipment for learners to observe one or more aspects of scientific principles or phenomena, providing students with the opportunity for engagement of Science and Engineering Practices and Cross Cutting Concepts.
