The Pythagorean theorem can be used to calculate distance if a right triangle is created.
The Pythagorean theorem states that a squared plus b squared equals c squared. This very similar to the distance formula.

Learn how to calculate force and distance using the work formula.
You can use the work triangle in order to help you calculate either force in Newtons or distance in various units.

03:01 What distance was your bike moved by a force of 20 N if the work was 1600 Joules?

Learn all about three types of sedimentary rocks. I cover clastic sedimentary rocks,chemical, and organic sedimentary rocks.
Clastic sedimentary rocks form when layers of sediment become compressed over time.
Chemical sedimentary rocks are created when saturated water precipitates.
Organic sedimentary rocks are created from organic material. Coal is an example of organic sedimentary rocks

Autotrophs vs Heterotrophs Producers vs Consumers

An autotroph is an organism that can self feed.The word autotroph comes from the Greek autos self and trophe nourishing.

Autotrophs are the producers in a food web.

Some common examples would include….

Autotrophs produce their energy from the sun in a chemical process called photosynthesis

They take Carbon Dioxide plus water and sunlight and produce sugar and oxygen

Autotrophs form the base of the energy pyramid.

A heterotroph comes from the greek word meaning heteros = another, different and trophe = nutrition
Heterotroph get their energy by eating other plants and animals.

They use
Sugar + oxygen to produce carbon dioxide + water and energy in the form of ATP

C6H12O6 + 6 O2 yield 6 CO2 + 6 H2O + Energy
This process is called cellular respiration

Some Heterotrophs that only eat plants, herbivores others eat only meat, carnivores others eat plants and animals omnivores while some heterotrophs feed on dead organic remains of other organisms decomposers

An atom is composed of a dense core called the nucleus containing protons and neutrons and a series of outer shells occupied by orbiting electrons
An electron shell may be thought of as an orbit that the electrons follow. The closest shell to the nucleus is called the "1 shell" also called "K shell", followed by the "2 shells" "L shell"), then the "3 shells" (or "M shell"), and so on.

A valence electron is an outer shell electron that is associated with an atom, and the formation of a chemical bond
Each shell can contain only a fixed number of electrons: For the first 18 elements, the valence electrons follow these rules. The first shell can hold up to two electrons, the second shell can hold up to eight electrons, the third shell can hold up to 8 The transition metals vary from these guidelines.
You can use the periodic table for the groups 1,2,13,14,15,16,17,18 in order to find the number of valence electrons in the outer shell with the exception of helium. For example, all elements in group two have 2 electrons in the outer shell.
Elements in the same period have the same number of energy shells. Period 2 will have two energy shells.
So let’s go through the elements
Up first is period 1 Element 1 is Hydrogen in group 1 and contains one energy shell and 1 electron
Element 2 Helium period 1 group 18 and is the one exception because it has 2 valence electrons in the outer shell

Now period 2 which each have 2 energy shells.
Lithium found in group 1 has 2 electrons in k shell and 1 valence electron in L
Beryllium is found in group 2 and has 2 electrons in k shell and 2 valence electrons in L
Boron Is found in group 13 and has 2 electrons in k and 3 valence electrons in L
Carbon Is found in group 14 and has 2 electrons in k and 4 valence electrons in L
Nitrogen Is found in group 15 and has 2 electrons in k and 5 valence electrons in L
Oxygen Is found in group 16 and has 2 electrons in k and 6 valence electrons in L
Fluorine Is found in group 17 and has 2 electrons in k and 7 valence electrons in L
Neon Is found in group 18 and has 2 electrons in k and 8 valence electrons in L
Now let’s move on to period 3 with 3 electron shells
Sodium Is found in group 1 and has 2 electrons in k and 8 electrons in L and 1 valence electron in m
Magnesium Is found in group 2 and has 2 electrons in k and 8 electrons in L and 2 valence electrons in m shell.

What makes a trapezoid a trapezoid? A trapezoid has two parallel sides and two nonparallel sides.
A trapezoid is a quadrilateral because it has four sides.
I also cover,
How to find the area of a trapezoid
The median
How to identify a trapezoid
The shape of a trapezoid
Number of sides
Is a trapezoid a parallelogram?

Newton's third law of motion is all around us. In this video, I show real-world examples of the 3rd law of motion.
Why is Newton's third law of motion important?
For every action, there is an equal and opposite reaction.
For example, when you skateboard and push backward, the opposite reaction is to drive the skateboard forward.
A jet moves forward when the exhaust moves backward. Another example of an opposite reaction to a force.
Other examples include paddling a boat, jellyfish, basketball, and a trampoline.
By watching these examples it will give you a better understanding of how motion works.

Friction is the force that opposes motion between any surfaces that are in contact. There are at least four types of friction: static, sliding, rolling, and fluid friction. Static, sliding and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases

Static friction occurs when an object is resting on a surface. The static friction between the boots and the snow allows this person to stand and shovel snow.
When you rub your hands together you experience sliding friction.
When you ride a bike you depend on the rolling friction of the tires.
Sky diving depends on fluid friction between the air and the parachute to slow down.

In this video, I cover many real-life examples of friction and how friction helps you in everyday life.

Desert Biome is found on every continent. A desert is an area that receives rainfall of 10 inches or less a year.
Deserts can be very hot or very cold.
For example, the Sahara desert is the largest hot desert, and the Gobi desert in China is very large and cold most of the year.
Animals and plants in the desert must have adaptations that allow them to survive on little water.

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.

Ocean Biome Characteristics
The earth is 70% water. 97% of this water is made up of our oceans and seas.

Most of us only experience the ocean from the beach or on shore. If you go underwater and out into the ocean you discover it is teaming with life.

The ocean can be divided into 5 major oceans
The Pacific which is the largest, the Atlantic, Indian, southern, and the Arctic ocean.

The ocean is teeming with life. It includes animals as large as a 40-foot humpback whale and as small as microscopic plankton.
It includes a huge variety of plants and coral reefs that stretch for miles.
It also includes the largest mountain range called the mid ocean ridge.
The ocean impacts our weather and has been used for thousands of years as trade routes.

We play on the beaches of oceans and wonder what can be found in the Mariana trench which is 32,000 feet deep.

So there you have a very quick overview of our most diverse and largest biome-the ocean

Air masses are large bodies of air with similar temperature and humidity throughout.
In the video, I cover maritime and continental air masses. Maritime air masses form over the water and continental air masses form over land.
In addition, there are maritime tropical, maritime equatorial, maritime polar along with several types of continental air masses.

How clastic rocks form. Sedimentary rocks are derived from igneous, sedimentary and metamorphic rocks.
Sedimentary rocks make up around 75 percent of the rocks at the earth's surface
Let’s take a look at how clastic sedimentary rocks form. Clastic sedimentary rocks are the group of rocks most people think of when they think of sedimentary rocks. Clastic sedimentary rocks are made up of pieces of pre-existing rocks called clasts.
These sedimentary rocks follow wedcc in order to form
Weathering:
Erosion
Deposition
Compaction
Cementation

What is Ecology the study of? Ecology is the study of how organisms interact with one another and their environment. In order to help understand what ecology is I give examples of Ecology.
These interactions can be between biotic and abiotic factors along with different levels of an organization like an organism, a community, a population or an ecosystem.

More Information

Most air masses form over cold areas called polar regions or warm tropical areas.
In addition, they will form over oceans and be moist. Air masses that form over the ocean are called maritime and they form over continents. Air masses that form over continents are dry and are called continental air masses.
Remember air masses take on the conditions of where they are formed.
Let’s take a look at all of the air masses the Earth has
Maritime tropical are warm and moist
Maritime equatorial are hot and moist
Maritime polar cold and moist
Continental tropical warm and dry
Continental polar cold and dry
Continental arctic and Antarctica very cold and dry

Selective breeding (also called artificial selection) is when humans use animal breeding and plant breeding to develop offspring with traits they desire.
Selected breeding has been practiced for years with plants and animals.
Selective breeding has been used with horses, dogs, rice, wheat and corn

Let’s look at some examples,
Look at these two dogs
This Chihuahua mix and Great Dane shows the wide range of dog breed sizes created using selective breeding

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

Learn the difference between a solvent and a solute. A solute plus a solvent equal a solution. The solute is the object that is dissolved and the solvent is the object that dissolves.
In this video, I provide several examples such as coffee and sugar.
The solvent is the water and the solute is the soluble parts of coffee, sugar, and cream.
