The most dangerous throat infection is epiglottitis, which infects a portion of the larynx (voice box) and causes swelling that closes the airway.
Next Generation Science Standards. From Wikipedia, the free encyclopedia. The Next Generation Science Standards is a multi-state effort to create new education standards that are rich in content and practice, arranged in a coherent manner across disciplines and grades to provide all students an internationally benchmarked science education..
A practice of science is to ask and refine questions that lead to descriptions and explanations of how the natural and designed world works and which can be empirically tested. A practice of both science and engineering is to use and construct models as helpful tools for representing ideas and explanations. These tools include diagrams, drawings, physical replicas, mathematical representations, analogies, and computer simulations.
