APPENDIX J can be applied through engineering to produce advances in technology. Advances in technology, in turn, provide SCIENCE, TECHNOLOGY, SOCIETY, scientists with new capabilities to probe the natural AND THE ENVIRONMENT world at larger or smaller scales; to record, manage, and analyze data; and to model ever more complex systems with greater precision. In addition, engineers’ efforts to develop or improve technologies often raise new ques- tions for scientists’ investigations.

CONCLUSION In the decades ahead, the continued growth of the world’s popu- lation along with technological advances and scientific discoveries will continue to impact the lives of students. Whether or not they choose to pursue careers in technical fields, they will be asked to make decisions that influence the development of technologies and the direction of scientific research that cannot be imagined today. Consequently, it is important for teachers to engage their students in learning about the complex interactions among sci- ence, technology, society, and the environment.
