Boiling point and Melting point--
The boiling point is the temperature at which a substance changes from a liquid into a gas.
The boiling point varies for different substances and can be used to help identify elements of the periodic table and other substances. For example, water and rubbing alcohol look similar but water has a boiling point of 212 f and 100 c and rubbing alcohol has a boiling point of 180.7 f and 82.6 c
The element found on the periodic table with the lowest boiling point is helium at -452.1 f and -269c
Tungsten has the highest boiling point at 10,030 f which is 5660 c
Boiling point varies with your elevation. It is higher at sea level and decreases as you gain elevation. As a result,
The standard boiling point has been defined by IUPAC since 1982 as the temperature at which boiling occurs under a pressure of 1 bar which is a fancy way of saying the standard boiling point is the boiling point at sea level
The melting point is the temperature at which a substance changes from a solid to a liquid.
This snow melting is an example of the water reaching it’s boiling point.
The melting point is also impacted by atmospheric pressure which changes with elevation but not as boiling point does.
The melting point is a physical property and can be used to identify substances.
The melting point of water is 32 f and 0 c
Helium has the lowest melting point at -272 c and carbon has the highest at 3500 c
Compare this to steel which has a melting point of 1510 degrees c

How to create a mind map. Mind maps can help convert several pages of notes into a helpful picture that helps visualize your notes.
A mind map can be created from your notes and can be a very effective method for condensing your notes into a format that is easy to study.
Once your notes are converted into a picture they are much easier to memorize.

How many dwarf planets are there in 2020?
According to the International Astronomical Union IAU for short, there are currently five planets classified and accepted as dwarf planets: Ceres, Pluto, Makemake, Haumea, and Eris.
These dwarf planets are much smaller than the Earth
Here is pluto compared to the Earth
Except for Seres, which is found in the main asteroid belt, these dwarf planets are located beyond Neptune in the Kuiper Belt.
For several years these celestial bodies were called plutinos because Astronomers didn't agree on how to classify them.

Learn about 1st class levers,2nd class levers, and 3rd class levers.
Levers are simple machines that are found in many tools you use at work and at home.
A first-class lever has the fulcrum in the middle and the load and effort on each side of the fulcrum.
2nd class levers have the fulcrum on one end and the load in between the fulcrum and the force.
A third class lever has the force in between the fulcrum and the load.
**** After listening to feedback from the comments the way I had the arrows it is confusing. I had the arrow on the load in the direction that it is acting on the load. This seems confusing. Also, I have a typo at the hammer and label it a 2nd class lever. I describe it as a 3rd class but label it a 2nd class. Sorry for the mistake.
As a result I created a new video, and added a nice mnemonic device to help memorize the different types.

Describe Nitrogen Cycle-Nitrogen cycle in simple terms
We can not just breathe in nitrogen and use it in our body like oxygen.
Instead, we must get our nitrogen from the food we eat.
Fortunately, we have bacteria that help recycle this nitrogen and put the nitrogen into a form we can use and ensures we won't run out of nitrogen.
Key Terms: Denitrification, nitrogen fixation, ammonification, nitrite, nitrate

The Earth spins or rotates about an imaginary line that passes through the North and South Poles of the planet. This line is called the axis of rotation
It takes the Earth 23 hours and 56 minutes to complete one compete for rotation.
We round this to 24 hours which we call 1 day
The Earth rotates from west to east which counterclockwise. As the Earth rotates, different locations on Earth pass through the sun's light.
As a result, the sun appears to rise in the east and set in the west
As the Earth rotates the side of the Earth-facing the sun experiences day time and the side facing away from the sun experiences night time.
So the earth’s rotation is responsible for us experiencing day and night
The Earth’s revolution is the period of time it takes the Earth to go around the sun.
It takes two objects in order for a revolution to occur
The Earth revolves around the sun
It takes the earth 364 .25 days to revolve around the sun
We round this to 365 days 12 months or 1 year
The Earth travels in a counterclockwise direction

What is a kite in Geometry?
A kite has four sides, therefore it is a Quadrilateral
One of the first things you may notice is that there are two pairs of different-length sides.
The perimeter of a kite is found by adding the length of all four sides.
You can find the area by using the diagonals of the kite. A kite has one diagonal that is longer than the other diagonal.

Examples of parasitism
This innocent looking bird called a cowbird lays her eggs in another birds nest and expects the unsuspecting mom to raise their young. If this bird kicks her eggs out of the nest the cowbird may destroy her nest. This is just one example of parasitism.
Parasitism is a symbiotic relationship in which one organism benefits and another organism is harmed and in some cases may die.
Let’s take a look at examples
Mosquitoes These annoying pests will show up at most picnics and start trying to have a meal at your expense. mosquitoes are carriers, or vectors, for some of humanity’s most deadly illnesses, and they are public enemy number one in the fight against global infectious disease. Mosquito-borne diseases cause millions of deaths worldwide
In a similar fashion, ticks will do the same to you, dogs, livestock. The latch on to their host and start eating. Ticks can infect their host with many diseases including Lyme disease.
Many worms are parasitic.
Leech
A leech is a segmented worm that attaches to a host like you and gets a meal from their blood. They secrete a chemical that actually prevents the blood from clotting.
If present in great numbers on a host, these can be debilitating, and in extreme cases, cause death.
E. coli
There are hundreds of different types, or strains, of the bacteria E. coli (Escherichia coli). Most of these are harmless and live in the intestines of healthy people and animals. But some strains of E. coli make a strong toxin that can cause a severe infection.
Mistletoe This plant you will see high in trees is actually a parasite. Mistletoe will attach to their host tree or shrub and then extract water and nutrients from the host plant.

Many times mass and weight are used to describe the same thing. However, these two measurements are different. In this video, I explain the difference between mass and weight.
Mass is a measure of how much matter something contains, which equals the number of atoms in it
Weight is a measure of how strongly gravity pulls on something
The SI unit for mass is kilograms
The SI unit for weight is the newton N

Weathering breaks down the rock, and erosion carries the rock away. In this video, I explain the difference between weathering and erosion.
Weathering weakens rocks and breaks the rock down using chemical or physical changes.
The physical changes may be abrasion, wind, water, or ice.
Chemical changes include oxidation, hydrolysis, and carbonation.
Erosion moves the broken down rock away. This may include wind, water, or ice.

Learn about the steps of protein synthesis, the creation of long chains of amino acids from DNA.
It begins in the nucleus with transcription and moves to the ribosome where translation takes place.
Translation occurs in the nucleus when RNA polymerase attaches to the DNA and unzips a portion of the DNA.
mRNA or messenger RNA begins to fill in the DNA.
RNA is similar to DNA but contains Uracil instead of thymine.
This strand of mRNA leaves the nucleus and travels to a ribosome where translation will begin.
The messenger RNA will be read three units at a time called a codon.
The anticodon on the transfer RNA aligns with the correct codon and delivers an amino acid.
This continues and a polypeptide chain begins to grow.
