In this video, I cover the factors that impact population size. A population is a group of organisms of the same species that live in a certain area.

Learn the difference between an endothermic reaction and an exothermic reaction.
Endothermic reactions take in energy and might be cold to the touch. Exothermic reactions give off energy and will sometimes be warm or hot to the touch.

At @MooMooMath and Science, we end our videos with kindness multiplies kindness. In each of my #shorts I like to tell a quick Kindness story in order to inspire myself and others to practice kindness.
Acts of kindness make a lasting positive impact on the people around you.

You can find all of my kindness stories in this playlist.

Learn how the blood flows through the heart.
Your heart pumps blood throughout your body.
Blood helps keep us alive by transporting oxygen to the cells, removing carbon dioxide, fighting disease, and carrying important nutrients that your body needs.
Your heart has four chambers. Your top chambers are called atriums, and the lower chambers are ventricles.
Blood travels to the lungs by the pulmonary arteries and back to the heart by the pulmonary veins.

What are diatoms?
Diatoms are a major group of algae and are among the most common types of phytoplankton.

Diatoms are unicellular organism, although they can form colonies
They have cell walls made of glass

Diatoms belong to kingdom Protista

There are at least 100,000 species of diatoms have been discovered,
Diatoms exist in large numbers in most bodies of water throughout the world. In fact, just one quart of seawater can contain millions of diatoms
They are primary producers and create and are a very large food source in the ocean


Diatoms are autotrophs and produce energy by photosynthesis.As a result,, diatoms need sunlight, carbon dioxide, and water. They are found in the ocean, fresh water, and even moist topsoil

Many Diatoms are microscopic, but some measure a millimeter across.

Diatoms contribute enormous amounts of oxygen to our atmosphere.

Two basic forms of these organisms exist. They are known as Centrales Centrales have radial symmetry and are most often found in oceans and are wheel-shaped. They can be found drifting near the surface, sunlight and absorbing nutrients.Pennales tend to be elongated

Many Pennales live in fresh water streams, swamps, ditches, or on the bottoms of shallow regions of oceans and estuaries.

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.

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.

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.

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.

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

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.

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.

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

Types of Faults in Geology explained and animated.
In this video, I cover strike-slip fault, normal fault and reverse fault.

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 all about the largest phylum of organisms, the arthropods.
Arthropods have an exoskeleton, a segmented body, and jointed appendages.
Common arthropods are insects, crabs, ants, and lobsters.

Learn which type of graph is best four your data. A line graph is helpful for data over time, and a bar graph is helpful for categories. This helps you decide which graph is best for data visualization and which type of graph to use.
