Thinking in Causation - Level 1 Cause & Effect

PS1.B: Chemical Reactions

Next Generation Science Standards Disciplinary Core Idea PS1B - Chemical Reactions In this video Paul Andersen explains how chemical reactions progress as bonds are broken and reformed reformed. He explains the difference between changes in state and changes in molecules. He discussed collision theory and explains why increases in temperature and concentration can increase reaction rates.

In this video Paul Andersen explains how chemical reactions progress as bonds are broken and reformed reformed.  He explains the difference between changes in state and changes in molecules.  He discussed collision theory and explains why increases in temperature and concentration can increase reaction rates.  He also discusses the conservation of matter in chemical reactions.  The video also contains a teaching progression for chemical reactions from grades K-12.

CCC2: Cause and Effect

Crosscutting Concept 2: Cause and Effect - Mechanisms and Explanation In this video Paul Andersen explains cause and effect its importance in science and engineering. He starts by addressing the chain of interactions that must be present to show cause and effect. He addresses the assumptions of universality and scale in determining cause and effect.

In this video Paul Andersen explains cause and effect its importance in science and engineering.  He starts by addressing the chain of interactions that must be present to show cause and effect.  He addresses the assumptions of universality and scale in determining cause and effect.  He finished the video with a progression of instruction from K-12.
 

SEP3: Planning and Carrying Out Investigations

Science and Engineering Practice 3: Planning and Carrying Out Investigations Paul Andersen explains how investigations are used by scientists to answer questions and by engineers to test designs. He delineates be investigative and observational science. He demonstrates the formation of a good question the design of an effective investigation.
