Investigate the details of each plant in the model by using the information tool.
Control mountain growth with a model, and watch as the plants adapt to the conditions on either side.
Record and annotate their results using the snapshot album.
Understanding is checked and reinforced through a series of questions.

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.)
