It was nominated for the 2010 British Academy Television Awards in the category Specialist Factual. Only in the last 200 years have we known what an element is – a substance that cannot be broken down further by chemical reaction. The Ancient Greeks, with no way of breaking open substances, could only base their ideas of the elements on what they could see: Earth, Fire, Water and Air. In the 16th century alchemists were busy trying to turn
Physics First chemistry class ... and the same can be said for some of the chemistry that really makes sense of biological phenomena.” For physics to be relevant to a chemistry course, students have to develop a truly fundamental understanding of the concepts of energy, force, and matter, beyond the context of specific applications like the inclined plane. Physics First Physics First is an educational program in the USA, that teaches a basic physics course in the ninth grade (usually 15-year-olds), rather than the biology course which is more standard in public schools. This course relies on the limited math skills that
