The earth has an abundance of water, and even appears blue from space. However, only a small percentage of the water on Earth is freshwater and much of this freshwater is either frozen or unattainable.n other words, freshwater only makes up roughly 3% of all of the water on Earth You will find the bulk of freshwater in these 4 main sources.
Surface waters ( Lakes, Rivers, Streams, Ponds, Swamps, marshes)
Glaciers and IceCaps
Groundwater ( Shallow and Deep)
Atmosphere
Learn how to solve percent of videos. In this video I solve,
80% of what number is 12.
In order to solve this video you can use the formula is over of equal percent over 100
Learn how to use the trip ratios to find missing side lengths. Do you remember SOHCHATOA ? This is an easy way to remember the trigonometric ratios. Sine equals opposite over hypotenuse, cosine is hypotenuse over adjacent, and Tangent equals opposite over adjacent.
Once you identify which trig ratio should be used finding the side length of the right triangle is straightforward.

Biodiversity and ecosystems.
Biodiversity is the variety of life in an area that is determined by the number of species in that area. In simple terms “ Biodiversity is the number of different individuals and life forms in an area.
As biodiversity increases so do the health of the ecosystem increases.
Think of it as if you were running a business.
You want your business to be healthy and make money. Imagine you sell shirts. If you only sold a black shirt with a heart you are limited and if these shirts go out of style you are out of business. If you have a variety of shirts as fashion changes you are better able to adapt to these changes and continue to make money.
As biodiversity increases the ecosystem has a greater ability to adapt to changes.
and a healthy ecosystem has a greater chance of recovering from disasters.
Biodiversity can be broken down into three types
Genetic diversity
Species diversity
Ecosystem diversity

In this video, I explain electric power in simple terms including watts, voltage, ampere, and coulombs.
Electric power is expressed with the letter P and equals voltage times Current and is written as
P = V x I
Voltage is measured in volts
Current is measured in amperes
A Coulomb is a measure of charge and it takes 6.24 x 10 18 electrons to equal a Coulomb

Learn how to find mean, median, mode, and range with a frequency table. A frequency table organizes data so finding the range is easy. For the range just subtract the smallest from the largest number.
The mode is the number that appears most often.
The median is the number in the middle and the mean is the average.
I show you how to find each of these statistics easily from a frequency table.
Learn how to calculate power using the formula for power which is work divided by time.

The Phanerozoic Eon is part of the geologic timescale.
This Eon consists of three major eras.
The Paleozoic era, the Mesozoic era, and the Cenozoic era.
The Paleozoic era is also called the "ancient life".
Life echinoderms, trilobites, and jawless fish roamed the ocean along with sharks.
Tetrapods crawled out of the ocean and started living on land.
Insects began to spread along with reptiles and amphibians.
The supercontinent Rodinia broke apart and then drifted back together creating Pangea.
The Mesozoic era is called the "age of reptiles".
Dinosaurs prospered during this era.
The Cenozoic era can be called the "age of flowering plants" or the age of the insects."
Mammals, flowering plants, and insects all prospered during this era.
Learn all about three types of sedimentary rocks. I cover clastic sedimentary rocks,chemical, and organic sedimentary rocks.
Clastic sedimentary rocks form when layers of sediment become compressed over time.
Chemical sedimentary rocks are created when saturated water precipitates.
Organic sedimentary rocks are created from organic material. Coal is an example of organic sedimentary rocks

Why do animals like insects, fish, zebras, and even Zooplankton migrate?
Animal migration is the periodic journey of an animal from one place to another and then back again. There are many examples of animals that migrate. Geese are one example. Geese migrate in search of favorable weather, a place to breed, and a food supply. In just 24 hours, these birds can travel 2,214 kilometers from Canada to the southern U.S. or vice versa.

Learn how to find the area of a square using the diagonal which creates a 45 45 90 triangle. The special rules of a 45 45 90 triangle can be used to find the side length.
Digestion begins in the oral cavity which we normally call the mouth. The mouth is responsible for mechanical and chemical digestion and prepares the food for digestion. I explain the role of the mouth in digesting food. The mouth has a very important function in digesting food..
The mouth has 32 teeth that help with mechanical digestion and amylase that helps with chemical digestion.
Learn how to read a dichotomous key which is used in classification in order to help identify objects.
In this example, I classify 3 monsters. The first thing to remember is to always start at 1A with each new object that you are classifying. Because each question has two parts you should always start at the A question and then the question will tell you where to go next.
