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

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?

In this video, I look at 6 physical properties, thermal conductivity, states of matter, density, solubility, ductility, and malleability.
Physical properties can be observed without having to change the object.

What does a chemical equation tell you?
A chemical equation is the written expression of a chemical reaction.Welcome to MooMooMath and Science
In this video I would like to talk about chemical equations.
Chemical reactions occur all around us.
They can be exciting like these fireworks, also helpful like these fires..
A chemical reaction can be represented using a chemical equation.
Let's breakdown this chemical equation and see what information it contains.
First,the reactants are on the left of the arrow and products are on the right of the arrow
This equation has methane which is ch4 combining with oxygen which is O2
The plus marks on the left of the arrow tells which elements or compounds are combining
The arrow tells you what it will produce or yield. The right side of the arrow are your products or what is produced
The products in this equation are co2 which is carbon dioxide and h2o or water.
Each capital letter represents a new element and each element has a symbol. The symbol for every element can be found on the periodic table.
A number behind a letter tells is a subscript and represents how many ions of the element are in the chemical equation
H20 tells you that the compound has two hydrogens and 1 oxygen
What do the numbers in front of a letter tell you?
Coefficients are the numbers in front of the formulas
the coefficients give the number of moles of each substance involved in the reaction. In the example reaction 2 H2 + O2 yields 2 H2O
two moles of hydrogen react with one mole of oxygen and produce two moles of water.
Atoms are neither created nor destroyed.
In other words it must be balanced.
If you count the atoms with this reaction you will notice that it is not balanced.
This new equation is balanced because you have equal numbers of elements on both sides.
I will leave a note in the show notes for a video I created on balancing equations.
You can also indicate the physical states of the reactants and products
Here are some symbols
S = solid
l = liquid
g = gas
and aq = dissolved in water
In this chemical equation you have a solid plus a liquid and it produces a hydrogen gas dissolved in water.
So there you go
chemical equations
Reactants on the left, products on the right

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.

Malleability and Ductility-- Malleability and Ductility
Malleability is the ability of an object to be hammered into shapes.
Most metals are malleable.
Copper, gold, and silver are very malleable.
Ductility is the ability of an object to be stretched into wires.
Ductility and malleability are physical properties.

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".

The deciduous forest biome is known for having four seasons and trees that drop their leaves in the winter.
This biome is located in the eastern half of the United States, Canada, Europe, parts of Russia, China, and Japan.
The deciduous forest has moderate winters and warm summers. It receives around 50 inches of rain a year. This rainfall allows trees like oak, maple, and beech trees to grow in this forest.
You will find bear,fox, and deer in this biome

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

The cytoplasm is the fluid found in cells.
Cytoplasm is found in eukaryotic and prokaryotic cells.
The fluid of cytoplasm is called cytosol. It is made up mainly of water
The organelles are found floating in this liquid along with many other items
You can almost think of the cytoplasm as a crowded swimming pool
