Paleozoic EraPaleozoic era was 544 to 245 million years ago
Paleozoic means “ ancient life” and is part of the phanerozoic eon along with the cenozoic, and mesozoic eras
Let’s hit some highlights of this era
Early during the Paleozoic era trilobites, echinoderms, and other marine invertebrates such as coral dominated the oceans.
Jawless fish also lived during this era
Evently sharks and other bony fish appear
However, as time passed life did not remain in the sea.
Land plants began to appear such as ferns and some trees later in this era
Life was also crawling out of the ocean
The first vertebrates appeared Among these vertebrates was a tetrapod which was a vertebrate that could live on land
Other vertebrates would appear including snakes,crocodiles,
Reptiles and insects scatter throughout the world and amphibians appear
The supercontinent Rodinia brook apart early in this era, but by the end of the era the supercontinent Pangea was formed.

How does oxygen enter the body. The respiratory system is designed to exchange oxygen for carbon dioxide. The respiratory system is vital for the production of ATP. The mitochondria uses oxygen in order to produce ATP. In addition, it is designed to get rid of the waster product carbon dioxide.

What are the different types of solutions?
Isotonic which means equal
Hypertonic which means above
Hypotonic which means below
Tonic means strength

Commensalism Examples
Commensalism is a symbiotic relationship in which one organism benefits and the other organism is neither helped nor harmed.
The examples include egret bird and cattle, orchids and trees, barnacles, burdock weeds, and remora

Learn what an ion is in chemistry. You can produce a charged atom by taking a neutral atom and adding or removing one or more electrons which are called an ion
A positively charged ion is a cation
A negatively charged ion is called an anion.

In this video, I cover the relationship of visible light and the electromagnetic spectrum. Visible light is found betwwen infared waves and ultraviolet waves.
White light is made up of different colors. You can use ROY G BIV to help remember the colors that make up white light.

Boiling point and Melting point--

The boiling point is the temperature at which a substance changes from a liquid into a gas.
The boiling point varies for different substances and can be used to help identify elements of the periodic table and other substances. For example, water and rubbing alcohol look similar but water has a boiling point of 212 f and 100 c and rubbing alcohol has a boiling point of 180.7 f and 82.6 c
The element found on the periodic table with the lowest boiling point is helium at -452.1 f and -269c
Tungsten has the highest boiling point at 10,030 f which is 5660 c

Boiling point varies with your elevation. It is higher at sea level and decreases as you gain elevation. As a result,

The standard boiling point has been defined by IUPAC since 1982 as the temperature at which boiling occurs under a pressure of 1 bar which is a fancy way of saying the standard boiling point is the boiling point at sea level

The melting point is the temperature at which a substance changes from a solid to a liquid.
This snow melting is an example of the water reaching it’s boiling point.
The melting point is also impacted by atmospheric pressure which changes with elevation but not as boiling point does.
The melting point is a physical property and can be used to identify substances.
The melting point of water is 32 f and 0 c
Helium has the lowest melting point at -272 c and carbon has the highest at 3500 c
Compare this to steel which has a melting point of 1510 degrees c

The cell membrane surrounds the cell and protects the cell, communicates with other cells, and controls what enters and exits the cell.
The cell membrane is made of phospholipids which have a polar and nonpolar end.
The cell membrane also has proteins and carbohydrates.
In this video, I cover what the cell membrane is made of and the structure and function of the cell membrane.

Learn the difference between myopia and hyperopia
Myopia which is also called nearsightedness is when you can see items up close clearly and distance objects are blurry.
Hyperopia is the opposite. You can see distant objects clearly and objects that are close are blurry.

Learn about the characteristics of reptiles.Some common examples of reptiles include,
The four main reptile groups are the Turtles and Tortoises, Snakes and Lizards, Crocodiles and Alligators, and Tuatara

In your middle school science class or in Earth science you will hear about the lithosphere.
The Lithosphere is the top rigid, rocky portion of our earth
There are two types, the continental lithosphere, and the oceanic lithosphere.

The lithosphere is also divided into large tectonic plates.
These plates were one large continent called Pangea that broke apart.

A description of 11 body systems. I cover, muscular,urinary,respiratory,digestive,endocrine, reproductive,lymphatic,integumentary,muscular, and the circulatory system.

Learn how to set up a basic tree diagram and then solve for the total number of choices and the probability of a certain event.
In this tree diagram probability example John has to decide what to wear to school. He needs to decide on his shirt, pants, and shoes.
The tree diagram will help you figure out the total outcomes and the probability.

Learn how to code from DNA to mRNA to tRNA to amino acids.DNA is made up of four bases Adenine Cytosine Guanine and Thymine
Let's shorten this to ACG and T
A pairs with T and G pairs with C
So if we have this strand. It moves from 5 to 3
For a complementary strand, you will have
a will pair with t, t with a g with c and you can watch the rest.
Now messenger RNA is similar to DNA but instead of thymine, you will have uracil.
After decoding the mRNA and tRNA you can use an amino acid chart and find the correct amino acid.

At 2:21 I mislabel tRNA. Sorry for the mistake. Here is an updated video correcting the mistake.

Reading a ruler that measures in inches.

Reading a ruler can be a little tricky. What do all of these marks represent?
The ruler is divided into inches which are represented by numbers and then each inch is subdivided into smaller equal units.
In this video, I use a ruler divided into half an inch, one fourth an inch, and one eighth.
With a little practice you will find easy an inch ruler or tape measure can be easy.

Let's learn our cardinal directions which are also called your cardinal points.
What are the different directions found on a compass rose?
An easy way to remember this is to use Never Eat Soggy Waffles
If you go in a clockwise manner you get North East South West
So let’s apply the directions again
Finally, you can add directions in between the four main directions.
Between north and east, you can add northeast, between east and south you add southeast
Between south and west add southwest and final between west and north add northwest
These are intermediate measurements.
Cardinal directions are very helpful when using a map.

Although you may not see it, gravity is a force of erosion. Gravity not only influences the movement of water, but it also causes rocks and soil to move downward. This downward movement caused by gravity called mass movement plays a major role in shaping the Earth.

Sand, rocks, and soil will move downhill until the slope becomes stable. The angle of repose is the steepest angle at which loose material will not slide downward. The angle of repose may change based on the size, weight, shape, and moisture level of the objects which may cause rock falls or landslides.

The most destructive mass movement happens suddenly and rapidly.

A rockfall happens when loose rock fall down a steep slope. This steep slope may be manmade when creating a rode or created by nature.
Rocks that range in size from small fragments to large boulders fall down the slope due to gravity.

A landslide is the sudden and rapid movement of a large amount of material downward. A slump is the most common landslide and happens when a block of material moves downward over a curved surface.

A rapid movement of a large mass of mud is a mudflow. When heavy rain mixes with soil and rock a slippery mass of mud may be created that can flow rapidly downhill.

Mudflows as a result of a volcano are called Lahars. Volcanic eruptions or heavy rains on volcanic ash can cause a Lahar that may travel up to 80km an hour.
Sometimes the mass movement is very slow. This is called creep. Water loosens the soil on a steep slope, Plant Roots and animals loosen the soil which slowly moves downhill. Bent tree trunks may be evidence that creep is occurring.
