Learn how we classify living things using taxonomic rank. There are 8 levels of classification.
How do you create names for organisms that can be used anywhere in the world? This is where taxonomic classification, also called the Linnaean system, comes into play. Change music
Named after its inventor, Carl Linnaeus, a Swedish botanist, zoologist, and physician, the Linnaean classification system has 8 levels of classification. You may also hear this called a taxonomic rank. You will often see the levels displayed like a triangle. This is because the levels at the top are broad and general whereas the levels at the bottom are more specific. As you move down levels of taxonomic classification, the organisms will be more similar to one another.
The 8 levels of Taxonomic Classification are:
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
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 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.

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.
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.
Difference between angiosperm and gymnosperm plants.
Angiosperms are flowering plants.
Their seeds are enclosed in a protective covering called fruit.
Gymnosperms have a naked seed and many are cone bearing trees.

What is the Carbon cycle? The carbon cycle is one of several biogeochemical cycles found on Earth. Carbon is found in almost all living organisms and makes up around .04 percent of our atmosphere.
What are the steps of the carbon cycle and how does the Carbon cycle work?
Carbon may travel several paths including,
The atmosphere, the terrestrial biosphere, the earth’s interior which includes the lithosphere, the ocean, and human influence like burning fossil fuels and other objects that store carbon.
In the video, I go through a carbon cycle diagram and explain each step.
Carbon can be found in several forms including carbon dioxide and methane.
The carbon cycle is essential for many ecosystems on Earth.

Types of Proteins and their function in the human body
Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. Proteins are put together at ribosomes from a blueprint stored in DNA and more specifically from sections of the DNA called genes. There are 20 different types of amino acids that can be combined to make a protein. The order of amino acids determines each protein’s unique shape and its specific function or job.
Let’s take a look at 5 important functions of proteins
Messenger Proteins.
Enzymatic Proteins
Structural Proteins
Defensive Protein

A rate is a comparison of two quantities that have different units.

10 Mutualism Examples
Mutualism is a symbiotic relationship in which both organisms involved in the relationship benefits from the relationship.
In this video, I introduce 10 examples of symbiotic relationships that are mutualistic.
Examples include,
clownfish and sea anemone,
termites and flagellates,
oxpecker,
pistol shrimp and goby,
bee and plants
acacia plant and ants
spider crab and algae

The Law of Conversation of Mass states that the mass of the reactants must equal the mass of the products in all chemical reactions.
I use a simple demonstration to show this point. I use baking soda and vinegar which is a simple chemical reaction, to demonstrate the law of conservation.
Correction:
0:41 I accidentally said grams instead of ounces while weighing the materials. My mistake.
Learn about an energy pyramid and how the transfer of energy is demonstrated. A trophic pyramid shows where most of the energy in an ecosystem can be found. Each level is called a trophic level and as you move up trophic levels 90% of the energy is lost.
The Earth is 70 % water. However, only 3% of this water is freshwater. Much of this freshwater is frozen in glaciers, you will find some of the water in rivers and streams, and almost 30% of this freshwater is groundwater.
But What is groundwater? Groundwater is water that finds it way between the gaps of rocks and sediments underground.
As the water seeps into the ground it may find it’s way into an aquifer. Aquifers are underground rock layers saturated with groundwater. An aquifer is not an underground river but large porous layers of rock.
Learn about the first four planets called the terrestrial planets and the gas giant planets called the Jovian planets.
The terrestrial planets include Mercury, Venus, Earth, and Mars.
These planets are small, rocky, and close together.
The Jovian planets in Jupiter, Saturn, Uranus, and Neptune.
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.

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.
