The National Science Education Teaching Standard states that teachers should "select teaching and
assessment strategies that support the development of student understanding and nurture a community of
science learners." The combination of scientific inquiry with ‘real' data in the classroom would meet this standard
and improve teaching methods, providing the scaffolding necessary for inquiry-based learning. The introduction
to and use of real scientific data by students at a primary or secondary level would require from the teacher careful
preparation and a detailed understanding of the material presented, but could improve the students' learning
experience and increase the level of interest in scientific careers. This poster presents an example of an inquiry-
based lesson driven by real scientific data. In the lesson, students were shown scanning electron micrographs
of natural objects, such as flower pollen and mineral samples, and were allowed to examine the actual objects
from which the micrographs were taken. Through guided discussion and conjecture, the relationship between
the microscale features and the macroscale objects was explored. The students were prompted to explain the
functional significance of the microscale features, e.g., the reason for the ridges on the surface of the pollen, and
allowed to develop hypotheses to evaluate against the objects at hand. The students were encouraged to reach
conclusions, and these conclusions were not evaluated to be correct or incorrect; the teacher's role was to
facilitate observation and reasoning. The discussion about features apparent in the images but not in the actual
samples provided an introduction to the importance of scientific methods and tools in many modern occupations
and research areas. Using micrographs to show students an application of multi-scale images in the real world
allowed them to have experience with real data and also allowed them to learn in a more hands-on and less
controlled environment. This approach to science learning seemed to help to build interest and understanding of
natural phenomena and engage students in science more so than a traditional lecture format.
