Digestion begins in the oral cavity which we normally call the mouth. The mouth is responsible for mechanical and chemical digestion and prepares the food for digestion. I explain the role of the mouth in digesting food. The mouth has a very important function in digesting food..
The mouth has 32 teeth that help with mechanical digestion and amylase that helps with chemical digestion.

Learn how to find the area of a square using the diagonal which creates a 45 45 90 triangle. The special rules of a 45 45 90 triangle can be used to find the side length.

The Phanerozoic Eon is part of the geologic timescale.
This Eon consists of three major eras.
The Paleozoic era, the Mesozoic era, and the Cenozoic era.
The Paleozoic era is also called the "ancient life".
Life echinoderms, trilobites, and jawless fish roamed the ocean along with sharks.
Tetrapods crawled out of the ocean and started living on land.
Insects began to spread along with reptiles and amphibians.
The supercontinent Rodinia broke apart and then drifted back together creating Pangea.
The Mesozoic era is called the "age of reptiles".
Dinosaurs prospered during this era.
The Cenozoic era can be called the "age of flowering plants" or the age of the insects."
Mammals, flowering plants, and insects all prospered during this era.

In this video, I explain electric power in simple terms including watts, voltage, ampere, and coulombs.
Electric power is expressed with the letter P and equals voltage times Current and is written as
P = V x I
Voltage is measured in volts
Current is measured in amperes
A Coulomb is a measure of charge and it takes 6.24 x 10 18 electrons to equal a Coulomb

Learn how to use the trip ratios to find missing side lengths. Do you remember SOHCHATOA ? This is an easy way to remember the trigonometric ratios. Sine equals opposite over hypotenuse, cosine is hypotenuse over adjacent, and Tangent equals opposite over adjacent.
Once you identify which trig ratio should be used finding the side length of the right triangle is straightforward.

The atmosphere can be divided into four individuals layers separated by changes in air temperature. These layers are the troposphere, stratosphere, mesosphere, and thermosphere.

Each layer is classified according to the temperature. As you gain elevation in the troposphere the temperature drops. The temperature range is from around 15 degrees celsius to negative 45 to 50 celsius at the top
The temperature of the stratosphere actually gets warmer with elevation and ranges from minus 45 to 50 degrees celsius at the bottom to 0 degrees celsius at the top.
The mesosphere is similar to the troposphere and the temperature decreases with elevation.
The temperature ranges from 0 degrees celsius to negative 90 degrees celsius at the top.
Finally, the thermosphere gets warmer with elevation. The temperature ranges from negative 90 degrees at the bottom to over 1500 degrees celsius at the very top

As you move from the troposphere to the thermosphere the atmospheric pressure decreases.
As you go up in elevation the atmospheric pressure decreases and as you down in elevation the atmospheric pressure increases.
In 2012 Felix Baumgartner completed a freefall parachute jump from the stratosphere. During this jump, he reached speeds of over 800 miles per hour and broke the sound barrier. He was able to reach speed because the atmospheric is so thin there was very little friction to slow him down.

Use this simple technique to find the lowest common denominator of any fractions. If you can create a factor tree you can easily find the common denominator

Real-life demonstrations for the hydrologic cycle which is commonly called the water cycle. You may be familiar with this picture of the water cycle. Water moves around and around and is constantly moving. In order to help you understand and remember the hydrologic cycle, I will show you a quick demo of these 9 key steps.
Evaporation Condensation Precipitation Transpiration Infiltration Groundwater, Aquifer Run-off, and Accumulation.

Nervous System controls the human body by sending electrical signal through out your body.
The nervous system can be divided into the central nervous system and the peripheral nervous system.

The spleen is located in the upper left abdominal cavity, just beneath the diaphragm, and next to the stomach. It is similar to a lymph node in shape and structure but it is much larger.
An easy way to remember the anatomy of the spleen is the 1×3×5×7×9×11 rule. The spleen is 1" by 3" by 5", weighs approximately 7 oz, and lies between the 9th and 11th ribs on the left-hand side.
Your spleen is considered part of the lymphatic system.

the spleen consists of two types of tissue called white pulp and red pulp. The white pulp is lymphatic tissue consisting mainly of lymphocytes around arteries. The red pulp consists of sinuses filled with blood and lymphatic cells,

As blood is filtered through the spleen old and damaged red blood cells are removed from the blood. In addition, the spleen produces lymphocytes in response to invading pathogens found in the blood. The spleen is like a large lymph node that filters blood instead of lymph looking for invaders like harmful bacteria. White blood cells stored in the spleen help remove and eliminate these invaders. It is particularly helpful when fighting meningitis and pneumonia

The spleen also stores blood. The sinuses in the red pulp of the spleen are filled with blood and can be used in case of an emergency.

You can live without your spleen. your immune system won’t shut down without a spleen, but it won’t operate as efficiently.

Learn how to solve problems involving Boyle's law. Boyle's law states that as pressure increases then volume decreases and pressure decreases volume increases.
I use the Boyle's law formula Pressure x Volume = K
Example problem:
3.00 L of a gas is at 740.0 mmHg pressure. What is its volume at standard pressure?

A gas occupies 12.3 liters at a pressure of 40.0 mm Hg. What is the volume when the pressure is increased to 60.0 mm Hg?

The sodium-potassium pump is a type of active transport that moves 3 sodium ions into the cell and 2 potassium ions out of the cell. I cover why the pump is needed and provides an overview of this type of active transport cells use to move important objects into and out of the cell.
ATP is used to change the shape of the carrier protein allowing the sodium and potassium to move across te cell membrane.

In this video I cover what causes the ocean to have tides. The gravitational pull of the moon and sun cause tides. Spring tides occur when the sun and moon line up and Neap tides occur during 1st and 3rd quarter.

A factor tree allows you to find the prime numbers of a number.
Once you know the prime numbers then you can easily find the square root.
In this video, I find the,
The square root 50
The square root of 9
The square root of 25

Our blood helps keep us alive.
Your blood makes up around 7% of your body weight
This equals between 1 and 1 and a half gallons 4.5 to 5.5 liters
Your blood is considered a connective tissue.

Our blood has many important functions.
Here is a list of some of the major jobs
Transports oxygen to each cell.
Removes waste material like carbon dioxide.
Helps regulate your temperature and ph levels.
Fights disease and helps the immune system do its job.
Blood transports nutrients, such as sugars, fats and proteins, amino acids,
Along with hormones which are your chemical messages of the endocrine system.
It is made up of red blood cells, white blood cells, platelets, and plasma.

Learn how to write an equation f a line using y = mx+ b and this will allow you to write the equation slope intercept form.

Diffraction is the bending of light as it passes around the edge of an object or through a slit.
Refraction is the bending of a wave when it enters a medium where its speed is different.
When a wave passes through a slit it spreads out in waves as it passes through the slit.
