Exploring Energy

Article excerpt

The concept of energy is central to all the sciences. This recognition appears in the Next Generation Science Standards, where energy is not only one of the four high school physical science standards (HS-PS3) but also is considered a Crosscutting Concept (NGSS Lead States 2013). "Energy" appears in 395 places in the NGSS and is involved in Disciplinary Core Ideas in every science discipline:
