The relationship between cellular respiration and photosynthsis

What are diatoms?
Diatoms are a major group of algae and are among the most common types of phytoplankton.

Diatoms are unicellular organism, although they can form colonies
They have cell walls made of glass

Diatoms belong to kingdom Protista

There are at least 100,000 species of diatoms have been discovered,
Diatoms exist in large numbers in most bodies of water throughout the world. In fact, just one quart of seawater can contain millions of diatoms
They are primary producers and create and are a very large food source in the ocean


Diatoms are autotrophs and produce energy by photosynthesis.As a result,, diatoms need sunlight, carbon dioxide, and water. They are found in the ocean, fresh water, and even moist topsoil

Many Diatoms are microscopic, but some measure a millimeter across.

Diatoms contribute enormous amounts of oxygen to our atmosphere.

Two basic forms of these organisms exist. They are known as Centrales Centrales have radial symmetry and are most often found in oceans and are wheel-shaped. They can be found drifting near the surface, sunlight and absorbing nutrients.Pennales tend to be elongated

Many Pennales live in fresh water streams, swamps, ditches, or on the bottoms of shallow regions of oceans and estuaries.

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.

We are in the middle of tornado season. Although tornados can be fascinating, they can be very dangerous.

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

Types of Faults in Geology explained and animated.
In this video, I cover strike-slip fault, normal fault and reverse fault.

Longshore Drift which is also called littoral Drift involves the movement of sand and other items along the shoreline.
As prevailing winds push waves up the shore which is called swash, the backwash moves the sand back down which results in the sand moving in the direction of the prevailing winds.
