Unit 1: Evidence & Iteration in Science
Summary
In this unit, students are introduced to essential concepts in science in the context of issues related to technology and society. Students explore the nature of scientific evidence as they examine issues related to water quality and accessibility. They learn how advances in scientific tools and technology have enhanced human observations and provided more accurate and precise measurements (human senses and scientific tools and technology). Timelines from the history of scientific thought illustrate the use of such evidence in the iterative process of science, resulting in the development of scientific theories and a growing body of scientific knowledge. An attitude of scientific optimism has led scientists and others to persist despite obstacles, failures, and missteps, improving human understanding of a shared external reality that has resulted in ongoing scientific advancements. Case studies model science as a human endeavor that is accomplished by individuals and teams of people working together to utilize prior work, replicate studies, and contribute new ideas.
Unit Driving Question
How do people use evidence and iteration of ideas to construct scientific explanations that are relevant to everyday issues, such as water quality?
