"Thinking About Science Themes" covered in this article:
There are many ways to investigate a question or problem. When a scientist decides to study a problem, he or she must make many decisions. One decision a natural resource scientist must make has to do with time. Over how long a period should the problem be studied? Should the problem be studied over an hour's time? For 1 week? Or, should the problem be studied over a period of years? The scientist in this study observed the impact of her experiment on the natural environment immediately after the experiment was over. She also observed the same natural area 1 year later. Then, she observed it again after more than 12 months. Do you think that the natural area had changed during the time that she observed it? Do you think that her conclusions about the experiment changed over that period of time? Why or why not?
Specific "Thinking About Science" Themes:
  • Characteristics of Scientists
  • The Scientific Process

"Thinking About Environmental Themes" covered in this article:
One possible characteristic of an ecosystem is the ability to withstand a sudden crisis without changing very much. This characteristic is called resilience (re zil yentz). An example of a resilient (re zil yent) ecosystem is a natural sandy beach. When a storm or a hurricane hits, the beach may change its shape by losing or gaining sand. Overall, however, a sandy beach is resilient to storms and does not change very much in the long run. Another example is a flood plain, the flat land area on either side of a river. When the flood plain is not disturbed by human activities, in the long run it does not change very much when the river overflows its banks during a flood. The scientist in this study wanted to know whether a prairie is resilient to fire. Ecosystems are not the only things that may be resilient to a sudden crisis. What are other examples of resilience?
