Energy

The series of videos on enthalpy change continues with this look at the Gibbs Free Energy System and Spontaneity. Most students have heard the term, "spontaneous reaction," and Sal explains exactly what a spontaneous reaction is and how...

Sal continues his discussion of spontaneous reactions by setting up a reaction between two substances, and using the Gibbs Free Energy method to determine its spontaneity. This video is extremely heavy on the math, and it would be useful...

Everything around you is related to chemistry and more specifically, the energy within a system. The video explores how energy, in its different forms, changes after conversion — given off as heat or absorbed as heat  in chemical...

Energy has many forms ... but very few sources! How do we present this to young scientists? Explore the Definitions of Energy, PS3A, in a video about the Next Generation Science Standards. The narrator keeps it simple by relating each...

After learning how to dentify information on energy and its conservation. your class can work in groups to create an activity and lesson plan for elementary students, teaching all about energy and its conservation. Students demonstrate...

While science Jeopardy games are a dime-a-dozen, this one has some pretty unique categories that are still relevant to a middle school physical science curriculum. The topics include: leading nations, famous Americans (who invented...

Drive the clouds away from your day with this video. It thoroughly details how photovoltaics work and how clouds prevent us from relying solely on solar as an energy source. Unique knitted-object animation (bunnies, clouds, and all other...

Baby energy is not what it sounds like, it's better. Using a baby playing at the park as his model, this young man describes, provides solid examples, and works through a series of equations that show energy. Potential and kinetic...

When asked to list everyday objects that require energy, most people list technology that use batteries or electricity. Through hands-on exploration, young scientists discover energy is much more than just circuitry. They play with...

Fan the flames of inspiration by teaching energy conservation! The video's narrator explains the core ideas of PS3B, Conservation of Energy and Energy Transfer. Discover what pupils throughout the grade levels should know about energy...
