Learn how the tectonic plates move. Learn how the tectonic plates move. Alfred Wegener was the first Scientist to propose that the continents fit together like a puzzle and over time moved apart. His idea was brilliant but he had a problem. He couldn’t explain how the plates moved apart.

Since this time Scientists have proposed at least four mechanisms to explain how tectonic plates move over the Earth’s surface.
These four mechanisms include,
mantle convection
Ridge Push
Slab Pull
And Slab Suction

Cells are alive and in order to stay alive and maintain homeostasis the cell needs to move objects into and out of the cell.
Two methods a cell may use are passive transport and active transport.
In the video, I cover diffusion, endocytosis, exocytosis, facilitated diffusion, and pumps. Which are all ways cell transport materials across the membrane.

Mitochondria are amazing and cool
They are found in plants... animals,....fungi,.....protists, and any other eukaryotic cell

They can quickly change shape and move around the cell when needed.
When the cell needs more energy, the mitochondria can reproduce by growing larger and then dividing. For example, say you want to get in shape. As you exercise more the mitochondria in your muscles will increase in number and navigate to the edges of the cell, which allows these muscle cells to have more energy.
If the cell needs less energy, some mitochondria will die or become inactive.
The mitochondria are the powerhouse of the cell because of their ATP production. The function of the mitochondria is to boost your energy by performing cellular respiration.

Learn what a box and whisker plot tells you.

If you ask most people how long it takes the moon to revolve around the earth they would probably say a month or maybe 29 days?
In reality, there are two periods involved with the orbit of the Moon around the Earth.

Let's investigate!
The sidereal period is 27.3 and the moon is measured against stars.
The synodic period is 29.5 days and the moon is measured against the sun.

How do we breathe? The lungs and diaphragm work together to bring oxygen into the lungs and to move carbon dioxide out of your lungs.
The diaphragm is a large muscle that is found under your lungs. Your lungs are actually composed of millions of tiny air sacs and depend on the diaphragm in order to inflate
Your rib cage also helps out by having cartilage which allows the rib cage to expand and contract.
When you take a deep breath your diaphragm moves down and a low-pressure area is created and air flows into your nose and mouth. This process is your respiratory system hard at work.
Air enters the nose and mouth and enters the nasal passages.
Your nose and nasal passages have tiny hairs called cilia and mucus that help filter dirt and pollen out of the air.
The air next moves to the pharynx which is located at (the back of the mouth)
From the pharynx, it moves to the larynx which is commonly called the voice box.
the voice box (makes sounds when air
passes over the vocal cords)
Epiglottis: the flap of connective tissue that covers
over the larynx during breathing
It stands open during breathing, allowing air into the larynx. During swallowing, it closes to prevent choking on food

From the larynx, air travels to the Trachea which is a rigid tube made of cartilage.
The trachea leads into two tubes called the left and right bronchus
These tubes continue to branch until you reach a tiny air sac called a alveoli
At the alveoli, oxygen diffuses into the capillaries and carbon dioxide diffuse into the alveoli and is exhaled.
As you exhale the diaphragm moves upward and carbon dioxide and airflows out.

In physics, work is equal to force times a distance. The force and the movement must be in the same direction.

A simple phosphorus cycle explanation

Phosphorus is not found in the atmosphere. It is important for the production of ATP, DNA, and membrane.
Phosphorus follows a biogeochemical cycle that ensures the earth always has phosphorus and phosphate.
Substances like phosphorus, carbon, and nitrogen move from living organisms to abiotic factors This cycling from living organism to abiotic factor is a biogeochemical cycle.

Introduction to metamorphic rocks
Metamorphic rocks come from existing rocks that are subjected to extreme heat and pressure
Welcome to MooMooMath and Science and metamorphic rocks.
Metamorphic rocks are created when extreme heat and pressure changes the original structure into a new type of rock sedimentary igneous and even metamorphic rocks can all become
metamorphic rocks when exposed to heat and pressure. the original rock is referred to as the
protolith but it's commonly referred to as the parent rock.
Contact metamorphism occurs when existing rock comes into contact with extreme heat like magma inside the earth and becomes something new

Regional metamorphism is caused by extreme pressure. The pressure presses and squeezes the rock and transforms it. Kinda like gravity acts on this balloon. This will occur at convergent plate boundaries. Existing rocks are transferred into new rocks at these boundaries.

two major types of metamorphic rocks are foliated rocks which have a layered or banded appearance and non-foliated which do not have these bands or layers

You can test for proportionality on a graph by looking at various properties
A proportional graph will always go through the origin ( 0,0 )
A proportional graph will be a straight line
If you list points ( ordered pairs) from a graph you can create ratios and see if they are constant

An organ is a group of two or more tissue that works together to complete a common function.
Your body has around 78 organs.
In this video, I will cover several major organs.

The brain is the boss of your body. It runs the show and controls just about everything you do, even when you're asleep

The heart is a very strong muscle made of cardiac muscle that helps pump your blood throughout your body.

The kidneys are very important because they filter your blood and produce urine.

The spleen filters blood and acts like disease detectives. It also produces antibodies and lymphocytes which fight germs.

The Small and Large intestines are a major site of digestion. The small intestine is responsible for 90 percent of digestion. At the same time, the large intestines absorb salts, mineral, and vitamins.

The Liver Is a large organ with over 200 functions. It produces bile which helps with digestion, stores glycogen, and filters your blood to eliminate harmful bacteria and damaged cells.

The gallbladder stores the bile produced by the liver

Your stomach Is a site of digestion of the food we eat. After chewing our food it travels down the esophagus to the stomach.

The pancreas helps to regulate the blood sugar level of your body.

The skin protects us from disease,removes waste, and helps control our temperature.


Finally, the Lungs are responsible for exchanging oxygen for carbon dioxide

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.

In this video, I look at 6 physical properties, thermal conductivity, states of matter, density, solubility, ductility, and malleability.
Physical properties can be observed without having to change the object.

Each of these properties are examples of physical properties.

Difference between convex and concave Quadrilaterals.
A quadrilateral is a polygon so the same rules apply for a convex polygon.
A convex quadrilateral does not have angles greater than 180 degrees.
A concave quadrilateral has angles greater than 180 degrees.

Genotype and phenotypesYour genotype is your genetic code of your cells. This genetic code is responsible for many of your traits. The physical expression of your genotype is your phenotype.


Your genetic information is stored in your chromosomes on sections called genes.
A gene is a portion of DNA that codes for a trait.
The following picture illustrates this.
If you look at this drawing of a gene, the different sections are your genes.
In genetics you will encounter these three types of genotypes.
Homozygous dominant is written BB
Homozygous recessive bb
Heterozygous Bb
For each trait you get some information from mom and some from dad.
The different forms of the same trait are called alleles.
Take a look at the different hair texture. These different forms are alleles. It is still hair, just different forms.
A dominant allele will cover up or mask a recessive allele.
You will only get a recessive allele if both alleles are recessive.
Your phenotype is the actual expression of the genotype.
For example this dog has a round nose, this cat has black hair. These are physical expression of the genetic code.

Learn what an isotope is in chemistry. Isotopes are two or more types of atoms that have the same atomic number, which represents the number of protons and position in the periodic table but have different mass numbers due to different numbers of neutrons in their nuclei
In order to find the number of neutrons subtract the number of protons from the mass number.

Animal Behavior- Imprinting

Imprinting is an animal behavior in which new born birds and some mammals follow one of the first objects they see.
First mentioned by Konrad Lorenz it helps animals recognize their mother and other similar animal.
