ESS2.E: Biogeology
In this video Paul Andersen explains the topic of biogeology. Life only exists where the geosphere, hydrosphere and atmosphere allow life to exist. The interactions between the organisms on the planet and the planet itself is known as biogeology. As the landforms on the planet change the lifeforms adapt through evolution. The biosphere can also impact the Earth itself. A K-12 teaching progression is also included.
CCC4: Systems and System Models
In this video Paul Andersen explains how systems can be used to understand phenomenon in science and create better designs in engineering. He starts by defining the characteristics of a system and describes how system models can be used to better understand the world. For example a system model of the water cycle can show the cycling of matter on the surface of the Earth. He ends with a progression of instruction for a K-12 science classroom.
SEP7: Engaging in Argument from Evidence
Paul Andersen explains the importance of argumentation in improving both understanding and design. This video begins with a discussion of the heliocentric and geocentric model of the Universe that eventually lead to the Copernican Revolution. It highlights the importance of both informal and formal arguments. It finishes with a discussion of the educational progression including a great question.
