Types of Human Body Tissue
In this video, I review four types of tissue.
Connective tissue, epithelial tissue, muscle tissue, and nerve tissue.
Tissues are made up of cells working together.

Learn about the four Spheres of the earth.
The earth can be divided into four major spheres.
The biosphere which means life.
The hydrosphere which makes up all the water of the earth
The atmosphere which is the air of the earth
The geosphere which is all of the rocks, soil, and layers of the earth.
These four spheres of the earth allow life to exist on planet earth

Learn the difference between physical and chemical changes by observing real life examples.
Is mentos and diet cke a physical or chemical change? Actually it is a phase change so it is a physical change.
I include other example like breaking a piggy bank, fireworks, cutting hair and several other examples. The goal is to help you undertand the difference between a physical and chemcal change by looking at examples.

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.

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.

In this video, I would like to show some examples of diffusion.
Diffusion is when objects move from an area of high concentration to an area of low concentration.
Check out this example, of diffusion.
You can another simple example of diffusion when you watch the food coloring diffuse into the water.
If you take an egg and soak it in vinegar and then place it in water, the water will diffuse into the egg causing it to get larger.
If you place sugar into coffee it will diffuse out into the coffee.
Watering plants diffuses the water into the plants
When you go into Starbucks and smell the coffee smell the smell of the coffee has diffused through out the coffee shop.
You can soak a gummy bear in water and the water will diffuse into the gummy bear. and it will get larger.
Those are several examples of diffusion.
When objects move from high concentration to low concentration.

Kingdom of Protista
In this video, I review the kingdom Protista
A protist is a eukaryote that is not an animal, plant or fungi.
The kingdom protista is called the junk drawer kingdom because if a eukaryotic organism is not placed in the other kingdoms it is considered a protist.
There are three main types of protists, plantlike,animal-like and funguslike.
Some common examples of protists include amoeba , paramecium, kelp,algae,diatoms, euglena, and dinoflagellates.

What is a ribosome? A ribosome is an organelle found in plant, animal, and bacteria cells.
They are very small yet very important because they make proteins. Ribosomes use a process called translation to make proteins.

Pathway of Air Flow
Our journey of oxygen into the lungs and back begins when the brain stem sends a message to the diaphragm which is a muscle under the lungs.
As the diaphragm moves down the lungs expand.
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.
This process is repeated over and over again.

The Phosphorus Cycle is essential for life on Earth. It is considered a biogeochemical cycle.
In the video, I cover the phosphorus cycle steps.
Phosphorus is not found in the atmosphere but is found in rocks and is released by weathering.
Plants and animals absorb the phosphorus that is washed into the soil.
Eventually, the phosphorus is washed into sediment that is compressed into rock.

Biogeochemical Cycles - How the Earth Recycles
https://moomoomath.com/how-the....-earth-recycles-elem
Learn how biogeochemical cycles work. Important elements along with molecules like water are conserved by moving between living factors called biotic factors and abiotic factors which are nonliving factors. You can remember the elements that have biogeochemical cycles using CHNOPS
Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur.
Each of these elements has its own unique cycle and path from biotic and abiotic factors.

Macromolecules are large molecules that help keep the cell alive. What are macromolecules? You may also hear the term biomolecules to describe these large molecules
Cells of animals and most living organisms have four main macromolecules that help keep their cells alive and functioning properly.
The four main macromolecules are carbohydrates, proteins, lipids, and nucleic acids.

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
