Two items that provide engaging experiences on the nature of science,
from 3-D Molecular Design.

The Data Dilemma: Modeling Scientific Practice

3-D Molecular Designs has developed a simple but engaging lesson that helps students learn how models are developed, tested and modified with new information. The lesson uses Tangram pieces as examples of “information” used to build a particular shape, as a metaphor for how science works. Instructions are provided along with sample questions for class discussions.

In addition, the makers of this lesson have specified how it meets the national NGSS (Next Generation Science Standards), pointing out specific dimensions for: Scientific and Engineering Practices, Crosscutting Concepts, Disciplinary Core Ideas, and Engineering, Technology and the Application of Science.

The Mystery Tubes: A Black Box Activity

3-D Molecular Designs has developed a simple but engaging lesson that helps students learn how scientists approach a mystery in nature. Many times, the mechanism or explanation for a natural phenomenon is not directly accessible (too tiny, too far away, or hidden from direct view). Therefore, scientists create hypotheses (or models) for what might be the best explanation. They test this model in various ways and by observing the results of those tests. Hypotheses are either confirmed or rejected based on how well those observed results fit the predictions based on each hypothesis. This is essentially the purpose of other “Black-Box” or “Mystery Box” lessons. But this one poses a somewhat different mystery. It can also be presented as a “Magical Tube,” where you suggest that it works by “magic” or you have “supernatural powers,” and eventually get your students to realize why science cannot use supernatural or magical forces to explain the mysteries of nature. Instructions are provided along with sample questions for class discussions.
