How to promote personal hygiene
This is a basic question that you need to address carefully. The most important point is that you must be prepared for the theme you want to cover. The preparation must focus on gaining detailed knowledge and adequate information on that theme. This requires reading materials, collecting appropriate teaching aids and knowing the audience (educational background, their needs, behaviour, habits, etc.). Fixing the site, date and time is also important. You should identify the key messages you want to get across to your audience.
