PS3.A: Definitions of Energy

In this video Paul Andersen attempts to explain the age old questions - What is Energy?  Even though it comes in many forms one of the defining characteristics of energy is that it is conserved over time.  He then explains that all energy is either a function of motion, due to its position within a field or radiation.  A teaching progression K-12 is also included.

CCC3: Scale, Proportion, and Quantity

In this video Paul Andersen explains the importance of scale in science and engineering.  The Universe varies in size along three scales: size, timespan, and energy.  Many phenomenon are too small and fast, or two large and slow to observe.  We use the tools of proportion and units of measure to comprehend different scales.  The video ends with a progression of instruction from K-12

SEP4: Analyzing and Interpreting Data

Paul Andersen explains how scientists analyze and interpret data.  Data can be organized in a table and displayed using a graph.  Students should learn how to present and evaluate data.
