What is the pH scale? The letters pH stand for the potential of hydrogen and is a measure of the concentration of hydrogen ions in a water-based substance?
pH is organized into a scale of acids and bases with neutral. substances right in the middle
The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
pH is also organized by color. Red usually indicates an acid and blue usually represents a base.
In the video, I cover many pH examples including examples of acids you find around you and examples of bases.

Waves transfer energy without transporting matter. Waves are formed from vibrations and many travels through a medium. Light and radio waves do not need a medium.
Mechanical waves need a medium to pass through and I focus on two types, transverse waves, and longitudinal waves which are also called compressional waves.

The stomach is a major site of digestion. In order to digest food the stomach contains acid. This acid can be almost as strong as battery acid. The stomach also has mucus that protects the stomach from the strong acid.

Mesozoic EraIn this video I would like to talk about the Mesozoic era on the geologic time scale.
The Mesozoic era is part of the Phanerozoic Eon along with the Paleozoic and Cenozoic eras.
Mesozoic means “middle animals” and is a time of rapid change.
This era has also been called the age of reptiles and age of dinosaurs
The Mesozoic era was roughly 65 million years to 250 million years ago.
Let’s hit several highlights of this era
The Mesozoic era began after a mass extinction.
The shape of the continents looked different. At the beginning of this era, there was a super
Continent called Pangea. Over time this supercontinent broke apart and the continents started drifting apart.
The climate was warmer than today
The first mammals appear but are very small and they don’t begin to thrive until the Cenozoic era.
Dinosaurs also appear and begin to scatter and prosper.
The dinosaur population peaks during this era.
However, at the end of this era, the dinosaurs die off
The first birds appear and begin to scatter throughout the world.
The dominant plant is a cone-bearing tree and plants
At the end of this era, flowering plants begin to appear
So there we go the Mesozoic era,
Dinosaurs and cone-bearing plants

Difference between Organic and Inorganic Compounds
Organic compounds contain carbon. There are at least four important organic compounds, lipids, proteins, carbohydrates, and nucleic acids.
Inorganic compounds do not contain carbon and usually are more simple compounds.
There are some compounds that contain carbon and are inorganic like carbon dioxide.

Description of the major plate boundaries.
In the video, I include description of convergent boundaries. There are three types of convergent boundaries, continental to continental, oceanic to continental, and oceanic to oceanic.
Divergent boundaries are when lithospheric plates move away from each other.
Transform boundaries slide past one another.
