In 14 and ½ minutes, this slide presentation on YouTube gives an overview of the endocrine system: how it compares with the nervous system in terms of regulating body functions and the different classifications of hormones (this presentation limits the classifications to protein-based and lipid-based hormones). The video ends abruptly with a thorough description of how lipid-based hormones act on target cells. A marker is used to point out objects on the slide relevant to the narrative. A transcript is available. The narration is a female voice that is easy to listen to and comes across as very natural.

Evaluation and Observation
Contents are clear and concise
Includes an adequate amount of material
Contents cover core curriculum within the discipline
Provides a complete demonstration of the concept
Integrates the concept very well
Presentation ends in the middle of a concept. It would be nice to have finished this presentation with action of protein-based hormones on cells
Some of the information is not current
Potential Effectiveness as a Teaching Tool
The length of this allows it to be used to get across just a couple of learning objectives such as:
Definition of a hormone.
Principles of how the endocrine system functions
Compare and contrast neural and endocrine regulation of body responses.
Classes of hormones
Builds up on prior concepts
Does not identify learning objectives
Does not provide activities to reinforce concepts
Difficult to compare and contrast effects of lipid hormones and protein-based hormones which are in a separate presentation
