Acceleration is the measure of the change in velocity over time. The change in velocity can be a change in speed, direction or both.

The formula for average acceleration is
Final velocity-Initial Velocity over Time it takes to change

Acceleration is expressed in meters per second squared

Learn how compression and tension create mountains and mid-ocean ridges and trenches.
Compression is stress that squeezes an object.
Tension stretches an object.

What is a ribosome? A ribosome is an organelle found in plant, animal, and bacteria cells.
They are very small yet very important because they make proteins. Ribosomes use a process called translation to make proteins.

If you would like to learn more about proteins and their importance this video will help.

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.

Law conservation mass word problems.
In the video, I show two types of law of conservation word problems. The first problem involves counting atoms and the second problem involves finding the mass of the reactants and the products.
Example problem:
How much oxygen would add with 36g of carbon to give 136g of carbon dioxide?

Genotype and phenotypesYour genotype is your genetic code of your cells. This genetic code is responsible for many of your traits. The physical expression of your genotype is your phenotype.


Your genetic information is stored in your chromosomes on sections called genes.
A gene is a portion of DNA that codes for a trait.
The following picture illustrates this.
If you look at this drawing of a gene, the different sections are your genes.
In genetics you will encounter these three types of genotypes.
Homozygous dominant is written BB
Homozygous recessive bb
Heterozygous Bb
For each trait you get some information from mom and some from dad.
The different forms of the same trait are called alleles.
Take a look at the different hair texture. These different forms are alleles. It is still hair, just different forms.
A dominant allele will cover up or mask a recessive allele.
You will only get a recessive allele if both alleles are recessive.
Your phenotype is the actual expression of the genotype.
For example this dog has a round nose, this cat has black hair. These are physical expression of the genetic code.

Learn the difference between a pure substance and a mixture. A pure substance can be an element or a compound. A mixture can be homogeneous or heterogeneous.

Igneous Rocks explained in simple terms with examples.
In this video. I cover intrusive and extrusive along with mafic and felsic.
You can classify igneous rocks is to determine if the rock is mafic or felsic.
Classifying as mafic or felsic is actually a scale of the percent of silica found in the rock
0% to 45% is considered mafic and 65% or greater silica is felsic
45 to 65 is considered intermediate.
Mafic rocks are dark in color and felsic rocks are lighter in color
The names give you a clue as to what other minerals make up these rocks
Mafic can be broken in MA for magnesium and fic which is Latin for iron

Felsic is broken into fel for feldspar and sic for silica
In the video, I take a look at some mafic and felsic igneous rocks.

Difference between monocot vs dicot
Angiosperms are plants that have flowers and seeds encased in fruit.
Angiosperms can be divided into to major categories, monocots and dicots.
Monocots have one cotyledon and dicots have two cotyledons.

In this video, I review the major types of weathering of rocks.
Weathering of rocks is a physical or chemical change that changes the characteristics of rock on earth.
There are two major types
Physical weathering which involves breaking rocks into smaller fragments caused by environmental factors
Chemical weathering changes which involve rocks being changed into new substances or new minerals chemically.
Thanks for stopping by MoMooMath and Science. You can find additional information on weathering here.

How do thunderstorms form? In this video, I will cover the basics of these exciting storms.Here is how a thunderstorm forms
Step 1 Warm moist air is heated and begins to rise upward.
Step 2 As this warm air rises it begins to cool, condenses and begins to form clouds
Step 3 This warm air will continue to rise and will encounter cold air which will cool the moisture in the clouds and ice may form
Step 4 Eventually the cooled moisture and ice will begin to fall to the earth This action creates a downdraft
5. The updrafts continue feeding warm humid air and the falling moisture create downdrafts. This creates convection currents. You can see what convection currents look like. The warm water is in red and the cool water is blue.
These convection currents create the most violent stage of the thunderstorm
Lightning and strong winds are produced
6. Eventually the downdrafts will stop the updrafts of warm air
7 When the warm moist air is cut off the storm begins to dye off

There are three main types of thunderstorms; orographic, air mass, and frontal.

Mountains can form through folding, volcanism, and faulting.
Folded mountains form when rock layers are squeezed together and are pushed upward.
Many folded mountains occur at convergent boundaries where continental crust collide
The Himalayas stretch through the borders of China, Nepal, India, and Pakistan is the most towering mountain range on Earth,
Volcanic mountains are created when melted rock erupts onto the earth’s surface. Many volcanic mountains occur at convergent boundaries. Most of the active volcanoes on earth are concentrated around the edge of the pacific ocean.
Fault block mountains form when tension causes the lithosphere to break into normal faults.
At normal faults, the lithosphere drops down. The pieces left standing form fault-block mountains.

Learn the difference between an observation and an inference. An observations uses our 5 senses to make observations. These observations can be qualitative or quantitative.
An inference is an explanation of the observation based on prior experience.

X linked chromosomes explained,Humans have 23 pairs of chromosomes. One pair determine the gender of the child.A female will have xx chromosomes and males will have an x and a y chromosome
The x and y chromosomes not only carry the genes that determine male and female traits but also some other characteristics as well.
Since only men inherit Y chromosomes, they are the only ones to inherit Y-linked traits. The y chromosome carries around 200 genes.
There are about 1,100 human X-linked genes.
Most of them code for something other than female anatomical traits. Some X-linked genes are responsible for abnormal conditions such as hemophilia, red-green color blindness,
and "male pattern baldness".

Learn how to convert a mixed number, which is also called a mixed fraction, to an improper fraction. A mixed number has a whole number plus a fraction.
The denominator of the improper fraction is the same denominator of the mixed fraction.
You have a whole number part and a fractional part.
The denominator of the fraction tells you how many parts each whole number is worth.
The mixed number 2 and ⅔ each whole number is worth 3
Therefore, with 2 and ⅔ you have 3 times 2 which equal 6 parts plus you have 2 in the numerator so it becomes 6 plus 2 which equals 8 and you always keep the same denominator of the fraction so the improper fraction equals 8/3

A Coulomb is the SI unit for charge. It is equal to 6.24 x 10 to the 18th power.
Electric power is voltage times current. Voltage is equal to Joule/Coulomb and an ampere is equal to a Coulomb/Second. Let's take a look at what this SI unit for charge.
A Coulomb is also equal to 1 ampere ( the si unit for current) times 1 second
1C = 1A x 1s
In other words, if the current in a circuit is 1 ampere then 1 Coulomb passes a point each second.
1A = 1C/s

The Electromagnetic Spectrum is made up of EM waves that are composed of oscillating magnetic and electric fields. This is why they are called ‘electromagnetic’ waves.
The electromagnetic spectrum is ordered by a frequency which is the number of wavelengths that pass a fixed point per second. The electromagnetic spectrum contains radio waves, microwaves, light,x-rays, gamma rays, and more.
