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.
There are many more traditional foods associated with the Christmas season in Germany, and many are readily available here in the USA, such as Lebkuchen (gingerbread), chocolate Santas and various other Christmas confectioneries. In Germany, Christmas is also a time for baking PlÃ¤tzchen or Christmas cookies.
