Layers of the Earth based on chemical composition and physical properties
Earth can be divided into three layers based on chemical composition: the crust, the mantle,
and the core.
Earth is also divided into layers based on physical
properties, such as whether the layer is solid or liquid.
The five physical layers are the lithosphere, asthenosphere,
mesosphere, outer core, and inner core.

Annelida Phylum
Learn facts and characteristics about this phylum that includes the earthworm. This phylum of segmented worms is famous for their segmented bodies. In addition, these worms have a nervous system, a digestive tract, and are found all over the world.

The cytoplasm is the fluid found in cells.
Cytoplasm is found in eukaryotic and prokaryotic cells.
The fluid of cytoplasm is called cytosol. It is made up mainly of water
The organelles are found floating in this liquid along with many other items
You can almost think of the cytoplasm as a crowded swimming pool

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

Alfred Wegener developed the theory of Continental Drift. It states that at one time the continents were at one time one large land mass that broke apart and the continents drifted away from one another. The continents move away at a rate of about 10 cm per year.

The Electromagnetic Spectrum is made up of EM waves that are composed of oscillating magnetic and electric fields. This is why they are called ‘electromagnetic’ waves.
The electromagnetic spectrum is ordered by a frequency which is the number of wavelengths that pass a fixed point per second. The electromagnetic spectrum contains radio waves, microwaves, light,x-rays, gamma rays, and more.

Learn how the habitat and niche are different but also very important for a healthy environment.
A habitat is an ecological area where a plant or animal lives. It may be an island, a tree, or maybe under a rock. The habitat is where an individual can find food, shelter, protection and mates.
A niche is a role or position that an individual has in its environment. A niche may also involve what the individual eats, how it interacts with other living things, and also how it interacts with the nonliving factors. Without ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.

Grasslands are a large area of the earth that have lots of grass and very few trees. The grassland biome is found in South Africa, North America, Hungary, Argentina Uruguay, and Russia.

Temperate grasslands have hot summers and cold wintersTemperate grasslands can be further subdivided. Prairies are grasslands with tall grasses while steppes are grasslands with short grasses.
Steppes receive less rainfall than prairies and receive only 10 to 20 inches rainfall a year. dry areas of grassland with hot summers and cold winters.

Element vs Compound
An element is a pure substance. In other words, an element cannot be broken down into a simpler substance by physical or chemical means.An element is made up of only one type of atom. An atom consists of a proton, neutron, and an electron. Some common examples of an element would be carbon, oxygen, or iron. The elements are arranged in the periodic table based on their number of protons. For example, sodium has 11 protons, potassium has 19
The number of protons of elements always stays the same.
Each element also has its own unique set of properties.

A compound is a pure substance of two or more elements chemically combined. Elements combine during a chemical change. A particle of a compound is called a molecule.
When the elements combine chemically a new substance is created.
The compound has different properties than the elements that make it
Hydrogen and oxygen are gases but they combine to make liquid water.
Here are some items that combine to make compounds
Table salt is sodium and chlorine
Glucose is made of carbon-hydrogen-oxygen
When elements create a compound they always join in a specific ratio
The ratio of water is hydrogen to oxygen is 2 to 1
If a compound has a different ratio of hydrogen to oxygen then it is not water
Glucose a type of sugar has a ratio of c6 h12 o6 which is 6 carbons 12 hydrogens and 6 oxygens
Glucose will always have this same ratio
Compounds are all around you
In the food you eat, the school supplies you use, your clothes and even you

Digestive Enzymes are vital for our digestion. In this video, I cover these important proteins and where they are found in our digestive tract.
Digestion starts in the mouth where salivary glands start secreting enzymes. From the mouth, enzymes are added in the stomach, by your pancreas, and your small intestines.
Enzymes mentioned in this video
Lipase, Pepsin, Erepsin ,Maltase, Lactase,Sucrase
trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, pancreatic lipase, nucleases, and amylase.

A Coulomb is the SI unit for charge. It is equal to 6.24 x 10 to the 18th power.
Electric power is voltage times current. Voltage is equal to Joule/Coulomb and an ampere is equal to a Coulomb/Second. Let's take a look at what this SI unit for charge.
A Coulomb is also equal to 1 ampere ( the si unit for current) times 1 second
1C = 1A x 1s
In other words, if the current in a circuit is 1 ampere then 1 Coulomb passes a point each second.
1A = 1C/s

In this video, I describe the similarities and differences between prokaryotic and eukaryotic cells in clear and simple terms. My goal is to help you understand the difference between the different types of cells.
All living things are made of cells but they may be different.
First, cells can be prokaryotic or eukaryotic cells.
Prokaryotic cells can be classified as bacteria or archaea.
Eukaryotic cells can be classified as plant or animal cells.

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.
