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.
The insects are mostly scavengers and will feed on a wide variety of foods. They are especially fond of starches, sweets, grease, and meat products. In many locations, garbage is a principal food source. As with other species, German cockroaches are mostly active at night, when they forage for food, water, and mates. During the day they hide in cracks and crevices and other dark sites that provide a warm and humid environment.
