PowerPoints Drive the Randomized to Organized Lesson

Past and Present Arrangers of Chemical Element Systems PowerPoint

Three PowerPoints highlight a personage-oriented history of the development of element concepts and illustrations from ancient history leading to the current operative periodic tables for study and professional use.

NGSS, and particularly Crosscutting, is particularly well related to the historic backstory, creative genius', and technology of the later builders of periodic tables.
            Science: Chemistry, scientific methods, parts of atom, etc.
            Technology: Moseley: spectra, Seaborg: radioactivity, Lavoisier: experimentation
            Engineering: sorting and arranging: De Chancourtois' geology charting tool familiarity led to cylindrical/rotational portrayal of element arrangement, Alexander: integrated the d- and f-blocks to merge the main group blocks
            Math: determination of percentages and other measurements, numeracy in general
            History: From Ancient Greeks through the European Middle Ages up to the present

Having the students understand the need for order (and how to attain it) in a knowledge presentation is the core purpose of the Randomized to Organized lesson plan.

These PowerPoints are designed to provide additional aid to the teacher who wishes to help students understand the process of arriving at the first periodic table, the minds and methods of improving on it in many ways, and the probability that the process is incomplete even now.
