In physical and health education it is important for us to teach the students what being healthy means. One of the big things when doing this is talking to the students about what their body mass is and how it can affect them by either being to high or to low. In order to do this effectively we give them the tools to do it on their own so they may have a better understanding for its importance.
Some teachers feel that it is completely fine to use this method during class as long as the student agrees to it whereas, other teachers feel that it is not worth the risk to physically demonstrate it when they could just show this through other teaching media such as YouTube, diagrams, and text. The risks that I mentioned are discomfort to the student along with the possibility of lawsuits. In the society we live in nowadays lawsuits are becoming more common and it is important that as teachers we keep ourselves safe as well as our students. It is unfortunate but when there are other ways to teach this method why not do what we can to make it the best experience for everyone.
