Oh Deer!

Population: 

Today, students learned all about populations. We began by discussing world population and how it has increased from 1 billion to 7 billion people in just over 200 years. Students correctly identified China (1.3 billion) and India (1.2 billion) as the most populous countries in the world.  Students learned an important concept in population ecology – the Tragedy of the Commons. When people raise too many livestock or fish too much, they deplete the natural resources of an ecosystem, so no more food can be produced, and all of the people who depend on the land (or water) for their food suffer. So it is very important to take care of the land that we use–in other words, we must be good stewards of the Earth!

We also explored how populations fluctuate from year to year by playing the game “Oh deer”, in which students pretended to be deer hunting for important resources in the habitat: food, water, and shelter. Some students played resources that, if “eaten” by a deer, became deer themselves. Things got really exciting when we added wolves to the mix–some students got to be wolves, hunting deer to make more wolves. Besides being a whole lot of fun, this exercise showed students first-hand how growing populations deplete resources, but introducing new species, such as predators, to an area can balance out population fluctuations and sta

Ecología de Poblaciones: La Pesca de Respuestas

Hoy los estudiantes aprendieron sobre la Ecología de Poblaciones. La clase comenzó con una discusión de cómo la población mundial ha aumentado de mil millones a siete mil millones en solo 200 años. Los estudiantes identificaron que China (mil trescientos millones) e India (mil doscientos millones) son los países del mundo con la mayor cantidad de población.

Los alumnos también aprendieron sobre un concepto importantes:  la Tragedia de los Comunes. Ese concepto tiene que ver con el uso de los recursos por los rancheros. Cuando los rancheros tienen demasiado vacas en las tierras comunas, se destruyen los recursos y nadie se puede utilizar la tierra.

En un juego que se llama “Oh Deer!”, algunos estudiantes pretendieron que sean ciervos y otros estudiantes pretendieron que sean recursos de la tierra que los ciervos necesitaban para vivir. En ese ejercicio, los estudiantes aprendieron que los recursos son limitados, y cuando los ciervos comen demasiado, los recursos disaparecen. Entonces, unos estudiantes pretendieron que sean lubos que pudieron comer los ciervos y criar más lubos. De esta manera, los estudiantes aprendieron que la introducción de nuevas especies puede resultar en el equilibrio de la comunidad ecológica.
