"Forensics," in its most universal sense, is defined as the use of science or technology in the investigation and establishment of facts or evidence for determining identity or relatedness. Most forensic reasoning is used for arguing legal matters. However, forensic studies are also used in agronomy, biology, chemistry, geology, and physics to…

MOS, or Minds-On-Science, is the foundation of conducting educationally valuable science demonstrations. It is a teaching strategy equally effective as hands-on-learning. Plus, it proves much more effective at reinforcing abstract science concepts than traditional lectures, readings, and audiovisual presentations. Adding MOS to a demonstration…

Classroom demonstrations are a great vehicle for getting students to apply information they have heard in a lecture. Educational research is replete with data showing that concept application in an inquiry setting reinforces long-term science content retention. This means that students learn best when they experience applications of concepts and…
