Scientific names.
Let’s look at the scientific name of several common organisms.
Scientific name of a cat = Felis domesticus
Scientific name human = Homo sapien
Scientific name of a dog = Canis lupus familiaris


What does a scientific name tell us?
The name is a two part name. A fancy word for this is called “ binomial nomenclature.”
The first part of the name is the Genus and the second part is the species domesticus.

Humans belong in the genus Homo and the species sapien.

A cat would belong to the genus Felis, and the species
domesticus.
Plant-based names would follow the same rules when creating a scientific name for plants.

You may have to wear glasses. How do they work? When you are farsighted ( hyperopia) objects far away are clear but object close appear blurry. This type of problem can be fixed with a convex lens. A concave lens is used to fix the opposite problem created when you are nearsighted.

Learn the difference between potential energy which is stored energy and kinetic energy which is the energy of motion. In this video, I compare gravitational potential energy to kinetic energy. I also review the formula for potential energy and the formula for kinetic energy.

Bill Gates has a net worth of around 93,000,000,000 dollars.
This is a large number to write.
A nanometer is 1/ billionth of a meter which is written as 0.000000001 m

Both of these numbers can be written using scientific notation.
Bill Gates net worth could be written as 9.3 x 10^10
A nanometer can be written as 1.0 x 10^-9
Lets go over the basics of scientific notation

9.3 x 10^8
The coefficient must be between 1 and 10
The exponent should be an integer and can be positive of negative

If you have to move the decimal to the left , the exponent will be positive
If you have to move the decimal to the right the exponent will be negative

530,000 5.3×10^5
First example. In this example we do not have a decimal so you can assume it is after the last zero. The coefficient must be between 1 and 10 so we need to move the decimal five places to the left because 5.3 is between 1 and 10
The exponent will be positive so it will be written as 5.3 x 10 5

.00078 x 10^-4

In this example in order for the coefficient to be between 1 and 10 we need to move the decimal four places to the right 7.8 is between 1 and 10
We need to move the decimal to the right so the exponent will be negative

The scientific notation will equal 7.8 x 10^ -4

x-linked inheritance and male pattern baldness.
An x-linked trait which is a sex linked trait is a trait found on the x chromosome.
Females have two x chromosomes and males have an x and a y chromosome.
The x chromosome has almost 800 genes compared to only around 70 found on the y chromosome.

Let’s look at the Punnett Square for another x-linked disease, hemophilia
In this example, the father has the disease and the mother is a carrier.
With a recessive x-linked disease a female can be a carrier
Have the disease, or not have the disease.
Males can only have the disease or not.
Let’s go back to the Punnett square and their offspring.
This female is a carrier, this female has the disease, this male has not inherited the disease and this male has hemophilia.
Notice the Punnett square works similar to a monohybrid cross except the y is neither dominant or recessive. I will call the y chromosome neutral
Because males either have the disease or not, they have a greater chance of inheriting an x-linked trait.
So there you go, traits found on the x chromosome.

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.

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.

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

As the moon rotates around the earth it travels through phases.
The alignment of the sun, earth, and moon create the phases.
I use an orrery to explain the moon's alignment during,
new moon, waxing crescent, ist quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning crescent, and back to new moon.
The sidereal period is 27.3 and the moon is measured against stars.
The synodic period is 29.5 days and the moon is measured against the sun.

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

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.

In this video, I'd like to talk about the difference between a solar and lunar and discuss different types of eclipses. As the moon orbits the Earth its position changes and may block the sun.
eclipse, when the shadow of one celestial body like the moon or the earth falls on another an eclipse, occurs.
A solar eclipse happens when the moon comes between the earth and the sun and the shadow of the moon falls on part of the
earth a lunar eclipse happens when the earth comes between the Sun and the moon
and the shadow of Earth falls on the moon.
I show a diagram of a partial solar eclipse, total solar eclipse, and an annular eclipse.
In addition, I diagram the types of shadows, umbra, penumbra, and antumbra.
Finally, I diagram the different types of Luna eclipses, penumbral, partial lunar eclipse, and a total lunar eclipse.

Learn all about Igneous rocks which are produced from molten rock. Igneous rocks can be divided into two major types, intrusive and extrusive. Intrusive rocks are formed inside the Earth from molten rock. Intrusive rocks can have large crystals and a coarse texture. Extrusive rocks are formed from lava and will have small crystals and a fine texture.
I also show examples of igneous rocks including, obsidian, basalt, and rhyolite.

In this video, learn about the biome called the taiga. This biome is also called the coniferous forest or the boreal forest.
The taiga is found in the north and has very cold temperatures.
You will find moose,reindeer, and brown bear.

Longitudinal waves are waves in which the displacement of the medium is in the same direction as, the direction of propagation or movement of the wave. In other words, the displacement of the medium is parallel to the propagation of the wave

Longitudinal waves are also called compressional or compression waves, because they produce compression and rarefaction when traveling.
I also cover compressions and rarefactions.

In this video, I cover the difference between mechanical waves and electromagnetic waves. Mechanical waves need a medium in order to transport energy and electromagnetic do not.
