Reflective Questions (have your response ready by Friday and turn it in on Monday)

1. The current definitions of science as set forth by the American Physical Society Panel on Public Affairs (APS−POPA) read as follows:

“Science extends and enriches our lives, expands our imagination and liberates us from the bonds of ignorance and superstition. The American Physical Society affirms the precepts of modern science that are responsible for its success.

“Science is the systematic enterprise of gathering knowledge into testable laws and theories.

“The success and credibility of science are anchored in the willingness of the scientist to:

i. Expose their ideas and results to independent testing and replication by other scientists. This requires the complete and open exchange of data, procedures and materials.

ii. Abandon or modify accepted conclusions when confronted with more complete or reliable or observational evidence.

Adherence to these principles provides a mechanism for self correction that is the foundation of the credibility of science”

a) Give one example of how quality science extends and enriches our lives. Also give an example where quality science has failed to do this.

b) Give one example of how quality science expands our imagination.

c) Give one example of how quality science liberates one from the bonds of ignorance and superstition.

d) Do the above definitions jive with your definition(s) of science?
