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.

A description of 11 body systems. I cover, muscular,urinary,respiratory,digestive,endocrine, reproductive,lymphatic,integumentary,muscular, and the circulatory system.

Learn how to set up a basic tree diagram and then solve for the total number of choices and the probability of a certain event.
In this tree diagram probability example John has to decide what to wear to school. He needs to decide on his shirt, pants, and shoes.
The tree diagram will help you figure out the total outcomes and the probability.

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.

Reading a ruler that measures in inches.

Reading a ruler can be a little tricky. What do all of these marks represent?
The ruler is divided into inches which are represented by numbers and then each inch is subdivided into smaller equal units.
In this video, I use a ruler divided into half an inch, one fourth an inch, and one eighth.
With a little practice you will find easy an inch ruler or tape measure can be easy.

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.

Although you may not see it, gravity is a force of erosion. Gravity not only influences the movement of water, but it also causes rocks and soil to move downward. This downward movement caused by gravity called mass movement plays a major role in shaping the Earth.

Sand, rocks, and soil will move downhill until the slope becomes stable. The angle of repose is the steepest angle at which loose material will not slide downward. The angle of repose may change based on the size, weight, shape, and moisture level of the objects which may cause rock falls or landslides.

The most destructive mass movement happens suddenly and rapidly.

A rockfall happens when loose rock fall down a steep slope. This steep slope may be manmade when creating a rode or created by nature.
Rocks that range in size from small fragments to large boulders fall down the slope due to gravity.

A landslide is the sudden and rapid movement of a large amount of material downward. A slump is the most common landslide and happens when a block of material moves downward over a curved surface.

A rapid movement of a large mass of mud is a mudflow. When heavy rain mixes with soil and rock a slippery mass of mud may be created that can flow rapidly downhill.

Mudflows as a result of a volcano are called Lahars. Volcanic eruptions or heavy rains on volcanic ash can cause a Lahar that may travel up to 80km an hour.
Sometimes the mass movement is very slow. This is called creep. Water loosens the soil on a steep slope, Plant Roots and animals loosen the soil which slowly moves downhill. Bent tree trunks may be evidence that creep is occurring.

Use these short cuts to help you learn the 8 phases of the moon
The 8 phases are,
New Moon
Waxing Crescent
1st Quarter
Waxing Gibbous
Full Moon
Waning Gibbous
Last Quarter
Waning Crescent
It takes the moon 29.5 days to go through these 8 phases.
I provide pictures to help you learn the moon phases

Global conveyor belt and thermohaline ocean currents. The ocean has waves and currents. I think of currents as rivers of water in water.
Because cold water is denser than warm water, the cold water sinks below warm water. Water with a higher salinity has a greater density than less salty water. As a result, currents can be created in the ocean.

The global conveyor belt is a series of ocean currents that snake around the world. They are called thermohaline currents because they are the result of changes in temperature and salinity.

The base of the world’s food chain depends on the
cool, nutrient-rich waters that support the growth of algae and seaweed.

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
MGSE9-12.S.ID.2 Use statistics appropriate to the shape of the data distribution to compare center
(median, mean) and spread (interquartile range, mean absolute deviation, standard deviation) of
two or more different data sets.

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

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
