    ■ Warm up by talking about population.
    Hello, class. We have come to Module 11 Population. But what is population?
    A population is the number of living things in an area. A city's population is the number of humans living in that city. The population includes all ages and races that live in that certain area.
    Population density is the average number of people in a place. In areas with a high population density, people live close to each other. In areas with a low population density, people usually live far away from each other.
    Usually population is about the number of animals or humans there are in a certain area.
