Simple Thermodynamics of Transportation

Scholars learn about a series of three challenges when they design a bus system for a small town. They determine the bus routes and then figure out the best type of fuel to use before considering the cost of going electric. Learners...

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...

Sal's series on the Law of Thermodynamics continues with this video on how heat and work are added to, or taken away from, a system. As a result of the heat and work energy, the system that is being worked on will transform into another...

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 challenging in terms of math, and it would be...

Cells are busy places! How do things move around in such a tiny environment? Introduce young life scientists to the types of cellular transport through a video that is part of a large biology playlist. Animated characters demonstrate how...

Free energy, get your free energy here! Learners see that all organisms require free energy, which comes from the sun. The lesson explains the first two laws of thermodynamics and then analyzes metabolism, via glycolysis, on a very...

If renewable energy sources are the best option, why aren't they used on a global scale? Junior environmentalists explore the benefits and problems associated with energy sources such as solar, wind, and biomass with a short video and...

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...

Materials don't need a password to move through cell membranes! Learners explore how cells move materials across the cell membrane. The video then teaches the detailed workings of both passive transport (specifically diffusion,...

Energy is neither created nor destroyed, but what about free energy? Where does that fit into thermodynamics? In the video, learners explore simple the spontaneous reaction examples of enthalpy, entropy, and temperature, and then apply...
