In this video Paul Andersen describes some of the properties of electromagnetic radiation. The electromagnetic spectrum varies by wavelength from radio waves to gamma rays. We only see a portion of the spectrum known as visible light. A number of phenomenon (including refraction, emission spectrums, and gamma radiation) are discussed. A teaching progression K-12 is also included.
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.
Scientists and Engineers spend over half of their working day reading, evaluating and producing text. Therefore it is important that we produce students that have a high level of scientific literacy. Students normally struggle with scientific reading due to the high level of jargon and multiple modes of presentation (i.e. graphs, images, data). We can help our students become more scientifically literate by having them consume and produce scientific text from K to 12. Several strategies for teaching this progression (e.g. adapted primary literature and mini-posters) are included.
