The MAD is the average distance of all of the elements in a data set from the mean of the same data set
You can think of it as how far each piece of information is from the average
If you look at MAD you have the mean which is the average, the absolute value, and deviation.
The MAD indicates how spread out your data set is.
A large MAD indicates a data set more spread out relative to the mean.
A small MAD indicates a data set less spread out relative to the mean.

This video helps with the following Math Standard

(median, mean) and spread (interquartile range, mean absolute deviation, standard deviation) of
two or more different data sets.

These 9 phyla contain roughly 90 percent of all animals found on Earth. Phylum Porifera
Sponges are pretty basic animals with no specialized organs but they are filter feeders that suck up plankton and other organic matter found in the water

Phylum Annelida
This phylum is made up of Segmented Worms which include earthworms and leeches. This is a large phylum, with over 22,000 species including ragworms, earthworms, and leeches. In addition to having segments, these worms contain a digestive system, most have a closed circulatory system and a nervous system.

Phylum Nematoda – The Roundworms These worms inhabit some bizarre places. Inside your intestines, the hearts of dogs, or inside wasps. Nematodes are very small, slender worms: Many are parasites but others are free-living

Phylum Platyhelminthes – The Flatworms are ribbon-shaped worms that can absorb food and oxygen through their skin by diffusion.: Examples include planaria, and tapeworms Many are parasites and some like the planarian can regenerate a copy of themselves if it is cut in half.

Molluscs (Mollusca)
This phylum includes snails, clams, slugs, squid, and their relatives. Mollusks are the largest marine phylum, comprising about 23% of all the named marine organisms molluscs have a mantle with a significant cavity used for breathing the presence of a radula which is similar to a tongue and a nervous system.

Arthropods (Arthropoda)
The largest animal phylum, This phylum includes crustaceans, insects, arachnids, and other organisms. Arthropods have an exoskeleton, segmented bodies, and jointed appendages

Echinoderms (Echinodermata)
Include Sea stars, sea urchins, and sea cucumbers Echinoderms have radial symmetry and are found on the sea bed at every ocean depth Echinoderms contain a water vascular system that helps with gas exchange, feeding, sensory reception, and locomotion

Cnidaria
Cnidarians are famous for their stinging cells. This phylum contains
Jellyfish, and sea anemones They mostly have two basic body forms: swimming medusae and polyps, both of which are radially symmetrical

All of the previous phyla contain animals that are invertebrates which means they do not have a backbone
Chordates include animals that have a notochord most people call this the backbone and a spinal cord
The phylum includes
All types of fish,
amphibians,

reptiles,

birds,

All about clouds reviews the four main types of clouds along with where clouds are located in the atmosphere and pictures of clouds.
The four types of clouds and the names of clouds can help give you a clue about what the cloud will look like
Cirrus = are feathery and may bring fair weather in the immediate future
Cirrostratus are going to be wispy from cirrus and layered from stratus and are found high in the atmosphere
Cirrocumulus = will be wispy and fluffy and often bring fair weather for the near future
Altostratus = alto clouds are medium clouds and also appear as sheets.

How does the oxygen cycle work?
The oxygen cycle involves the movement of oxygen between biotic and abiotic factors.
the oxygen cycle maintains the level of oxygen in our atmosphere.
Processes within the cycle are considered either a source ( oxygen production) or a sink which involves oxygen consumption

Learn about the three different types of convergent boundaries.
Oceanic/Oceanic
Oceanic/Continental
Continental/Continental
Convergent boundaries create volcanoes, earthquakes, and deep trenches when the large tectonic plates made up of the lithosphere bump into one another.

Why does the same side of the moon always face the earth?
Because of the orbit of the moon and its rotation are almost the same the near side of the moon always faces the earth. The orbit of the moon is elliptical and has a slight tilt.

Gravity depends on mass and distance and is an attraction between objects with mass.

A spider looks like an insect, but a spider is not considered an insect.
A spider is an arachnid and is similar to an insect but also different.
Spiders have two body regions, eight legs, no wings or antennae compared to insects.
Are spiders bugs? No, but they have several similar characteristics

Divergent plate boundaries occur when two tectonic plates move away from one another.
Divergent plate boundaries are considered constructive boundaries.
If you look at a map of the major tectonic plates you can see several divergent plate boundaries.
There are two major types of divergent boundaries.
Continental and continental lithosphere and oceanic and oceanic lithosphere.
An example of an oceanic and oceanic divergent boundary is the mid-ocean ridge.
The mid-ocean ridge runs around the world including going right through Ice land.
A famous example of a continental and continental divergent boundary is the African rift valley.

Ecological Succession occurs when an ecosystem has a disturbance and must regrow. Succession is all about change.
There are two main types of succession, primary and secondary.
Primary occurs when an area has been almost destroyed and little life or soil remains.
Pioneer species are the first plants to regrow.
Secondary succession occurs where you have a disturbance but the soil remains.

When the earth or moon fall between the sun and one another shadows are created. In this video, I demonstrate what an umbra, penumbra and an umbra look like.
The umbra is the darkest portion of a shadow.
The prenumbra is the lighter edges of a shadow.
The antumbra is the shadow created at the end of the umbra

Excretory system
The excretory system removes waste and toxins from the human body.
Your skin eliminates waste by sweating.
Your lungs eliminate carbon dioxide.
Your kidneys filter over 180 liters of blood in order to produce urine.
The kidneys filter waste like urea. This liquid that is collected is called urine.
Your kidneys are made up of millions of filtering units called nephrons.

Transverse waves are waves in which the oscillation is at a right angle to the direction of the wave.
A transverse wave has a crest, trough, wavelength, resting point, wavelength, and frequency.
The following is a quick summary of the video.

Types of Animal Movement
In this video I show some of the different ways animal move. Some animals move on 4 legs, others on 2. Some animals move by oozing along, while others swim.

Learn how to create a dichotomous key. A dichotomous key is a method to identify objects like animals, rocks, trees, plants, and many other objects. In this video, I use monsters in order to show you how to create a simple dichotomous key. Dichotomous means two parts so the key uses two questions at each step. There are different types of dichotomous keys but in this video I show you how to make a simple key.

Nucleus Structure
What the parts of the nucleus?
Cell parts and function-I have always heard that the nucleus is the brain of the cell. But why is it the brain, and what are the major parts of the nucleus?
The nucleus is a large organelle. In fact, you can see the nucleus with a compound microscope.
Here it is inside a cheek cell.
I’m going to look at four main components of a nucleus and the role each part plays.
The nucleus is surrounded by a nuclear membrane. It is very similar to the cell membrane, and it is composed of two layers. It protects and houses the other parts of the nucleus.
You can also find ribosomes on the outside of the nuclear membrane.
Up next are nuclear pores. These are openings found on the nuclear membrane.
They allow items to move in and out of the nucleus. An example would be the mrna. It would travel through a nuclear pore to leave the nucleus.
Nucleoplasm This is a gel-like material found inside the nuclear membrane. You will find the DNA suspended in the nucleoplasm
Nucleolus. This is almost like a nucleus inside the nucleus. It has a very high concentration of DNA,
It is also the site of transcription which is the starting point of protein synthesis.
This is how the nucleus controls the cell. It has all the information on how to make stuff like proteins inside the cell. These proteins are used for many purposes inside the cell.
Ribosomes are also made at the nucleolus
All eukaryotic cells have a nucleus and bacteria and other prokaryotic cells do not have a nucleus.
