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.

Learn the diference between saturated,unsaturated, and supersaturated solutions.
Science Standard
When you have an unsaturated solution less solute then the solution is capable of dissolving is mixed in.
With a saturated solution there is so much solute present that if you were to add any more it will not dissolve and excess salt will fall to the bottom of the container.
If you mix in 40 grams of salt at 90 degrees into 100 grams of water.

A supersaturated solution contains more than the maximum amount of dissolved solute then the solvent is able to dissolve at a given temperature.

S8P1.a Develop and use a model to compare and contrast pure substances (elements and compounds) and mixtures.

How are concave and convex lenses different?
A convex lens is thicker in the middle compared to the edges. It is also called a converging lens because the rays and bent together. A convex lens is also called a positive lens because of the location of the focal point.
A concave lens is thinner in the middle compared to the edges.
It is called a diverging lens because the rays of light spread out.
A concave lens also is called a negative lens because the focal point is behind the lens.

Learn which type of graph is best four your data. A line graph is helpful for data over time, and a bar graph is helpful for categories. This helps you decide which graph is best for data visualization and which type of graph to use.

Equivalent Fractions look different but measure the same thing! I place several equivalent fractions on a number line in order to help you see that they measure the same things. Remember, a fraction measures parts of a whole.

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.

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.

The structure and function of the small intestines. This coiled organ which is part of the digestive system is found roughly behind your belly button.
How large is the small intestine? About 22 or 23 feet long.
The intestines are divided into 3 parts. The duodenum, the jejunum, and the ileum
The small intestines also contain hairlike projections called villi that help absorb nutrients

Learn how biogeochemical cycles work. Important elements along with molecules like water are conserved by moving between living factors called biotic factors and abiotic factors which are nonliving factors. You can remember the elements that have biogeochemical cycles using CHNOPS
Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur.
Each of these elements has its own unique cycle and path from biotic and abiotic factors.

Biogeochemical Cycles

The hydrologic cycle (water cycle) recycles water on earth. The water cycle drives our weather and allows life to exist on earth. Let ’s start with the evaporation of water from the surface of the ocean.
As moist air is lifted, it cools and water vapor condenses to form clouds. In fact, clouds are made up of tiny water droplets and ice crystals that are so small they can float in the air.
This moisture in the atmosphere may be transported around the globe until it returns to the surface as precipitation.
Precipitation may take the form of rain, snow, sleet or hail. Once the water reaches the ground, one of two processes may occur, some of the water may evaporate back into the atmosphere or the water may penetrate the surface and become groundwater. The groundwater may take several different paths.
Groundwater either seeps its way to into the oceans, rivers, and streams, or into an aquifer which is a body of saturated rock through which water can easily move, or it may be released back into the atmosphere through transpiration.
Transpiration occurs when leaves from trees and other vegetation give off water vapor through pores in their leaves.
Some water on the earth’s surface is not absorbed by plants or become groundwater and becomes surface runoff, which empties into lakes, rivers and streams and is carried back to the oceans, where the cycle begins again.

Estuaries are bodies of water in which salt and fresh water mix.
Estuaries have been called the "nurseries of the seas because they provide a safe area for fish, birds, and other animals to raise their young.

Estuaries can be classified based on their geographical features. The four main types include bar-built , coastal plain, tectonic esturary, and
fjord type estuary.

Heat is the transfer of energy from objects of different temperatures. As objects warm-up or cool down their kinetic energy changes. Kinetic energy is the energy of motion.
In this video, I focus on three ways heat can be transferred,
Conduction, Convection, and Radiation.
Conduction involves direct contact between objects and usually occurs among solids.

Convection is caused by unequal heating and the density of the different objects causes movement of fluid away from the heat source.

Radiation occurs without objects touching and occurs in space.
For example, the energy of the sun warms objects on Earth due to radiation.

I show several examples or demonstrations for each type of heat transfer.

Anaerobic Respiration Fermentation

Anaerobic respiration, also called fermentation, occurs when cells need energy but there is no oxygen for aerobic respiration. As a result, cells convert glucose into either ethanol or lactic acid.
Alcoholic respiration occurs in plants and yeast.
Lactic acid fermentation occurs in animals.

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.

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 to divide decimals. The key is to make sure the divisor doesn't have a decimal. You can always move the decimal to the right, but if you move the decimal for the divisor you need to also move the decimal of the dividend.

Protein synthesis in simple terms. I cover the steps of transcription and translation. The overall process involves DNA unzipping when RNA polymerase attaches and a strand of RNA is created. Rna is different than DNA because it contains the base Uracil instead of Thymine. This step is called transcription.
I next show the difference between transcription and translation by showing how the mRNA leaves the nucleus and attaches to a ribosome.
At the ribosome codons and anticodons put the amino acids together in the correct order to form the protein.
