Cute animations and an animated narrator lead young physicists through kinetic energy calculations. The law of conservation of energy is also explored. The quality of visuals is somewhat blurry, but because of the enthusiasm and clarity,...

Does matter ever just go away? Find out with this entertaining video that dives into a sweet investigation that involves cake and sweet drinks! Super scientists gain insight about the physical changes from chemical reactions and...

Get your blocks out! It's time to start building and learning about mass! Enthusiastic chemists get in-depth information about the conservation of mass and the way it applies to chemical changes. 

Show class members how to balance equations, keeping in mind the conservation of mass, with a video demonstration that provides a few sample problems and solutions. 

Energy can be either useful or useless, depending on you look at it! A video lesson examines how entropy works with the Law of Conservation of Energy. Scholars learn how Earth receives and uses photons from the sun in a state of low...

Many scholars are overwhelmed when asked to balance chemical equations because they don't understand subscripts. Directly address this common point of confusion with a video that explains how to count the number of atoms in...

First equations had numbers, then chemical equations had letters, then they added in numeric subscripts, now what is going on with the alphabetic subscripts? The sixth video in a 29-part series explains how states of matter symbols are...

Sea turtles face a lot of adversity: storms, predators on land and in the sea, and eggs that don't hatch, but the biggest threat to these magnificent and ancient creatures is human activity. From poaching to pollution, from trash to...

Now that scholars understand more of currency imbalance and artificially suppressed currency, Sal discusses motivations of the different actors. He briefly touches on the difficulty of unwinding a cycle like this once it has begun....

This lesson will define the first law of thermodynamics, and use examples to illustrate conservation of energy.

Did you ever want to see inside your student's minds while you are teaching a concept? Through this video, you can see the common assumptions student's hold about energy and how you can build on these ideas to explain the Law of...

This video segment adapted from NOVA explores the effects of the Glen Canyon Dam on the beaches, wildlife, and vegetation of the Colorado River.

This video provides information about the conservation of natural resources.
