6 Species Unlike Anything Else | Evolutionary Loners
What happens when a species is the only of its kind? This phenomenon is called a monospecific taxon. Studying these special species can help us better understand not just those sparse groups, but all life on this planet! Join Olivia...

Energy Reduction
The best form of energy available to the world is energy reduction. In this video Paul Andersen explains how energy conservation and energy efficiency and be used to decrease energy during peak demand. Tiered and variable pricing, as...

Environmental Systems
In this video Paul Andersen explains how matter and energy are conserved within the Earth's system. Matter is a closed system and Energy is open to the surroundings. In natural systems steady state is maintained through feedback loops...

The Greenhouse Effect
In this video Paul Andersen explains how the greenhouse effect and greenhouse gases keep our planet warm enough to be habitable. He explains how greenhouse gases keep heat closer to the surface. He finally shows how increases in...

Conservation of Atoms
In this video Paul Andersen explains how atoms are conserved in a chemical reaction. This can be seen in a chemical equation where the subscripts represent the atoms in the molecule and the coefficients represent the molecules. The mass...

Reaction Intermediates
In this video Paul Andersen explains how reaction intermediates are created in elementary steps and may not appear as either a reactant or product. Experimentation is used in Chemistry to identify reaction intermediates.

Systems and Objects
In this video Paul Andersen explains the differences between a system and an object. Depending on the scale it often times easies to view a system as an object if the constituent parts aren't relevant to the question being asked. He also...

Intermolecular Potential Energy
In this video Paul Andersen explains the importance of intermolecular forces in chemistry. Intermolecular forces exist between dipoles (like hydrogen bonds), between dipoles and induced dipoles (like Ar and HCl) and between induced...

Coral Bleaching
In this video Paul Andersen shows how increasing ocean temperatures causes coral polyps to release their symbiotic algae. This process of coral bleaching decreases the availability of energy for the coral and may eventually lead to coral...

Wave Amplitude
In this video Paul Andersen explains how the amplitude of a wave is a measure of the energy of the wave. He gives several examples of wave amplitude and shows you how to calculate the wave of a transverse and longitudinal wave.

Force-Time Graph
In this video Paul Andersen explains hot the force-time graph can be used to determine the impulse of an object. Since the impulse and the change in momentum are equivalent the graph can also be used to determine the change in momentum...

Mass and Energy
In this video Paul Andersen explains how mass can be converted to energy and energy can be converted to mass. The equation E=mc2 can be used to determine the amount of energy released from nuclear processes.

Scalar Field
In this video Paul Andersen explains how scalar fields can be used to show the distribution of scalar quantities. The most important scalar fields in AP Physics 2 deal with electric potential. Scalar addition can be used to combine...

Natural Ecosystem Change
In this video Paul Andersen explains how the Earth's climate will natural change due to interactions between the Sun and Earth, volcanism, and plate tectonics. Species may go extinct leading to adaptive radiation or may move to a...

Inertial Mass
In this video Paul Andersen explains how inertial mass is defined and measured. When a force is applied to an object or a system it will accelerate. Using Newton's Second Law of Motion (F=ma) you can calculate the inertial mass.

Contour Lines
In this video Paul Andersen explains how contour lines show areas of equal elevation or equal gravitational potential. Contour lines are used as an analogy for lines of equipotential in electric fields.
