Within the US, if you plan on teaching at the college or university level, you have the minimum degree requirement although a doctorate is preferred. If you plan on teaching within the public school system pre-K through high school, you will have to obtain certification for the courses you are teaching. You can do this through the Alternate Route Program offered in all states (that I know of).
Lunch. Traditionally, Germans eat their main meal during the day, between 12 and 2 p.m. However, today, the midday meal is often eaten away from home, i.e. at work. With the increase in health and weight consciousness, lunches are becoming more light, and sometimes are nothing more than a snack.
Breakfast, Lunch and Dinner. German breakfast habits are much the same as in other countries. A good, traditional breakfast includes bread, toast, and/or rolls, marmalade, honey, eggs, cold meats, such as ham and salami, various cheeses, all washed down with a strong cup or pot of tea or coffee. However, with today's busy lifestyles there is a growing trend towards eating a more simple breakfast.
