In this video, I cover 4 differents methods for determining which fraction is the largest.
Method 1. Is the one method. If the difference between the numerator and the denominator is 1, then the fraction with the largest numerator is the largest fraction.

Method 2. You can cross multiple and the largest product is the largest fraction.

Method 3. You can divide the numerator ( top number) by the denominator (bottom number) in order to create a decimal and compare decimals.

Method 4. You can find a common denominator and divide the denominator into this number and then multiply the numerator by the product. This allows you to compare similar fractions.

Freshwater biomes are ecosystems take contain water with a low salinity.
In this video, I cover rivers and streams, lakes and ponds, and wetlands.
Rivers are bodies of water that are moving. They begin at the headwater and usually dump. into a larger body of water.
Lakes and ponds can be small or very large bodies of water.
Wetlands include a marsh,swamp, bog or fen.

How is this city like a cell?
They both need to store water and other materials.
Welcome to MooMooMath and Science and organelles and in this video, I will cover the main functions of a vacuole.
Vacuoles store water and waste and other materials in eukaryotic cells. Remember these are cells with membrane-bound organelles and a nucleus.

Vacuoles are storage sacks in plants and animal cells protists but they are not found in
bacterial cells in addition to storing water, vacuoles also store enzymes, waste, and even old damaged organelles.

25 Facts about the lobes of the brain
http://www.moomoomathblog.com/....2017/12/25-facts-abo

Cerebrum Top part of the brain and the cerebrum is separated into four lobes.
Temporal,parietal,occipital, and the frontal

Cerebellum also called the little brain
Controls coordination, balance, and helps us talk and walk

Temporal Lobe Helps us process sounds, in other words, helps us hear. Also helps some with balance.

Parietal Lobe It is called the “association lobe” It communicates with other lobes.The parietal lobe is where information such as taste, temperature, and touch are integrated, or processed.

Occipital lobe This lobe is responsible for processing your vision

Frontal lobe Is responsible for executive function. This includes memory, impulse control, your emotions, planning, and organization.

The brain stem controls the flow of messages between the brain and the rest of the body, and it also controls basic body functions such as breathing,, heart rate, and blood pressure,

In this video, I describe the similarities and differences between prokaryotic and eukaryotic cells in clear and simple terms. My goal is to help you understand the difference between the different types of cells.
All living things are made of cells but they may be different.
First, cells can be prokaryotic or eukaryotic cells.
Prokaryotic cells can be classified as bacteria or archaea.
Eukaryotic cells can be classified as plant or animal cells.

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.

Learn the difference between a physical property and a chemical property. In this video, I cover 9 physical properties and several chemical properties in order to help you understand the difference between these different types of properties.

Where does the sunrise and set?
In this video, I will explain why the sun rises in the east and sets in the west.
The sun only sets due east two times a year.
During the spring and autumn equinox, the sun sets due east. After this, the sunsets either further north or south.

What causes tides on Earth. The moon, sun, and gravity work together to create tides. When the mon, and sun pull on the Earth with their gravitational force the Earth has tidal bulges. The side of the Earth furthest from the moon has a tidal bulge due to inertia and centrifugal momentum.
I also cover the unique spring tides and neap tides.

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.

The Mohs scale of hardness explained. How can I determine the hardness or the ability to resist scratching of this mineral?
It is the Mohs scale to the rescue. The Mohs scale has ten minerals that increase in hardness. Talc is a number one and is the softest and diamond is the hardest.
This scale can be used to identify minerals.

Quantitative data can be divided into two types, discrete and continuous data.In this video you will learn the differences between discrete and continuous data.

Transcript
Welcome to MooMooMath where we upload a new Math video everyday.
In this video I would like to talk about two types of quantitative data.
Discrete and Continuous
Discrete data is data that has distinguishable spaces between values.
Often it is data that is counted.
On a graph the ordered pairs are at specific locations, so the graph is not connected, but only points
Some examples of discrete data include,
Dogs
People
Tickets you have for a show.
Continuous data is data that falls on a continuum.
On a graph it is all of the points, and the points in between.
It is data that can be measured as finely as possible.
It is often a physical measure.
Discreet data will often will contain fractions or decimals.
Some examples of continuous data include,
Time
Age
Height
Weight
Let's look at two examples and see the differences between these types of data.
Family Members
Discrete 5 family members
Continuous: Range between 5 feet and 6 feet tall
Books, books on your book shelf.
The discreet data is that you have 6 books on your bookshelf.
Continuous data is that they range in height from 15 to 30 cm in length

Discrete or not?
Number of cows on a farm yes discrete
Age of the cows on the farm continuous

Number of points scored in a game. discrete
Amount of oxygen in the atmosphere continuous
Temperature is continuous data
Number text messages sent today discrete

In this video you will learn how a histogram is different than a bar chart.
Welcome to MooMooMath where we upload a new Math video everyday
In this video I would like to talk about the difference between a histogram and a bar graph.
A histogram and a bar chart both ways to graph data.
Both have an x and y axis, and both use a bar to display the data.
With a histogram the categories are numerical.
For example, notice on this histogram the x axis is the age of people in the room. The ages are grouped in a numerical range.
In this next example, the histogram is graphing the score on a test and the number of people who scored in each range.
Also, the bars of a histogram touch
A bar graph uses categories such as types of movies, color of eyes, and the bars do not touch
For example, in this bar graph the categories are grade level and the number of students in each grade level.
Notice that the bars do not touch
In another example, the categories are types of videos and the number of videos in each type.
Again, the bars do not touch
In summary, histograms have bars that touch and use quantities.
A bar graph have bars that don't touch and use categorical data.
