The concept of interdependence in an ecosystem and its effect on the evolution of populations is further explored through a model of a dam. Students build a dam in the middle of the field, dividing the ecosystem in half to illustrate the affects of geographic isolation. They watch as the grass and then the rabbit populations in that region shift to one variant in the population. When students remove the dam, they observe the ecosystem slowly return to its original state. (Evolution Readiness Activity 8 of 10.)

AAAS Benchmark Alignments (2008)

5. The Living Environment

5B. Heredity
  • 5B/P1. By the end of the 2nd grade, students should know that there is variation among individuals of one kind within a population.
  • 5B/P2. By the end of the 2nd grade, students should know that offspring are very much, but not exactly, like their parents and like one another.
5D. Interdependence of Life
  • 5D/E1*. By the end of the 5th grade, students should know that for any particular environment, some kinds of plants and animals thrive, some do not live as well, and some do not survive at all.
  • 5D/E3a. By the end of the 5th grade, students should know that organisms interact with one another in various ways besides providing food.
  • 5D/E4. By the end of the 5th grade, students should know that changes in an organism's habitat are sometimes beneficial to it and sometimes harmful.
5E. Flow of Matter and Energy
  • 5E/E2*. By the end of the 5th grade, students should know that some source of "fuel" is needed for all organisms to stay alive and grow.
5F. Evolution of Life
  • 5F/P1. By the end of the 2nd grade, students should know that different plants and animals have external features that help them thrive in different kinds of places.
  • 5F/E1. By the end of the 5th grade, students should know that individuals of the same kind differ in their characteristics, and sometimes the differences give individuals an advantage in surviving and reproducing.
  • 5F/M2a. By the end of the 8th grade, students should know that individual organisms with certain traits are more likely than others to survive and have offspring.

9. The Mathematical World

9C. Shapes
  • 9C/E3*. By the end of the 5th grade, students should know that graphical display of quantities may make it possible to spot patterns that are not otherwise obvious, such as cycles and trends.

11. Common Themes

11B. Models
  • 11B/E3** (SFAA). By the end of the 5th grade, students should know that a model of something is similar to, but not exactly like, the thing being modeled. Some models are physically similar to what they are representing, but others are not.
  • 11B/E4**. By the end of the 5th grade, students should know that models are very useful for communicating ideas about objects, events, and processes. When using a model to communicate about something, it is important to keep in mind how it is different from the thing being modeled.
11C. Constancy and Change
  • 11C/E1*. By the end of the 5th grade, students should know that some features of things may stay the same even when other features change.
  • 11C/E2b. By the end of the 5th grade, students should know that often the best way to tell which kinds of change are happening is to make a table or graph of measurements.
