Students learn that different species can arise from a common ancestor if different groups have different selection pressures.

This activity places the control of the environment under the student's control. A field starts off with a uniform light level, and thus capable of growing plants with medium-sized leaves. Students can alter the environment by "growing" a chain of mountains through the field. Students are challenged to grow the mountains to their maximum height (corresponding to the maximum change in light level on either side of the chain) while maintaining a viable population of plants on each side. (Evolution Readiness Activity 4 of 10.)

AAAS Benchmark Alignments (2008)

1. The Nature of Science

1A. The Scientific Worldview
  • 1A/E2**. By the end of the 5th grade, students should know that science is a process of trying to figure out how the world works by making careful observations and trying to make sense of those observations.

5. The Living Environment

5B. Heredity
  • 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.
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/P2. By the end of the 2nd grade, students should know that some kinds of organisms that once lived on Earth have completely disappeared, although they were something like others that are alive today.
  • 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.
  • 5F/M2b. By the end of the 8th grade, students should know that changes in environmental conditions can affect the survival of individual organisms and entire species.

11. Common Themes

11B. Models
  • 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.
  • 11B/M1*. By the end of the 8th grade, students should know that models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.
11C. Constancy and Change
  • 11C/P2. By the end of the 2nd grade, students should know that people can keep track of some things, seeing where they come from and where they go.
  • 11C/P4*. By the end of the 2nd grade, students should know that some things change so slowly or so quickly that the changes are hard to notice while they are taking place.
  • 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/E2a*. By the end of the 5th grade, students should know that things change in steady, repetitive, or erratic ways—or sometimes in more than one way at the same time.
