ESS3.B: Natural Hazards
In this video Paul Andersen explains how natural disasters (like earthquakes, tsunamis, volcanoes and flooding) have affected and will continue to affect humans on the planet. Many of the natural hazards (like volcanoes and storms) can be studies directly and some (like earthquakes) can be predicted. Natural hazards will never go away but the damage can be limited. A K-12 teaching progression is also included.
ESS3.A: Natural Resources
In this video Paul Andersen explains how the resources required for survival come from the Earth. The resources are not evenly distributed on the planet and neither are the humans. According to the NGSS we need to limit the use of nonrenewable resources (like oil and coal) through regulations and increase the use of renewable resources. A teaching progression K-12 is also included.
CCC2: 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.
SEP6: Constructing Explanations and Designing Solutions
Paul Andersen explains how scientists modify theories by constructing explanations. He also discusses the cycle of design used by engineers to solve problems. He starts by defining a theory as a well-established explanation of a phenomenon that is refined over time. Examples discussed in the video include the big bang theory, the germ theory and the theory of natural selection. He also lays out a progression for building this skill in students.
