Learn how to find the slope from a graph. The slope can also be called the gradient of the line.The slope is a measure of the rate of change of a line or the steepness of a line. The slope is represented by the letter m
Using a graph you can calculate the slope by using rise over run. The rise will be how the line changes vertically and the run is the change in the x-axis or horizontal change.

Learn proportion basics. In this video, I show you how to work problems in which you find the value for x in a proportion.
Example problems include,
3/5= x/15
x/6 = 15/18
In order to solve these problems you cross multiply and then solve for x

Real-life demonstrations for the hydrologic cycle which is commonly called the water cycle. You may be familiar with this picture of the water cycle. Water moves around and around and is constantly moving. In order to help you understand and remember the hydrologic cycle, I will show you a quick demo of these 9 key steps.
Evaporation Condensation Precipitation Transpiration Infiltration Groundwater, Aquifer Run-off, and Accumulation.

Properties of the igneous rock rhyolite
Light in color there it is classified as felsic

Rhyolite contains over 70% silica which gives this rock it a light color
Because the crystals are so small it is an extrusive igneous rock and cooled quickly
in rhyolite the crystals are often too small to see. This is due to the rapid cooling of the rhyolite lava
Rhyolite is produced by violent volcanic eruptions.
Density 2.4 -2.6 g/cm3
The texture of Rhyolite is fined grain and is classified as aphanitic
In summary
Igneous
Felsic
Extrusive
Fine-grained Aphanitic

Learn the difference between a autotroph and a heterotroph. All plants and other organisms that produce their own food in an ecosystem are called autotrophs. Or self feeders
An Autotrophs is an organism that collects energy from sunlight or inorganic substances to produce food.
A Heterotroph is an organism that gets its energy requirement by consuming other organisms.
They are also called consumers
A heterotroph that eats only planed is called a herbivore
Heterotrophs that eat other heterotrophs are called carnivores. Lions,wolves
An organism that eats plants and animals are omnivores.

In this video, I cover 3 types of convergent boundaries.
Oceanic and Oceanic, Oceanic and Continental, Continental and Continental lithosphere
I also cover 2 types of divergent boundaries.
Divergent boundaries occur when plate boundaries move away from one another.
Oceanic and Oceanic plus Continental and Continental
Transform boundaries occur when plates move past one another.

Use this simple technique to find the lowest common denominator of any fractions. If you can create a factor tree you can easily find the common denominator

The Pythagorean theorem can be used to calculate distance if a right triangle is created.
The Pythagorean theorem states that a squared plus b squared equals c squared. This very similar to the distance formula.

Grasslands of the world. Learn about the grassland which is found in South Africa, Europe, Russia, and North America.
This biome is known for having grass and very few trees. The grasslands have occasional droughts and fires along which can prevent large numbers of trees from growing.

Introduction to Biomes

The atmosphere can be divided into four individuals layers separated by changes in air temperature. These layers are the troposphere, stratosphere, mesosphere, and thermosphere.

Each layer is classified according to the temperature. As you gain elevation in the troposphere the temperature drops. The temperature range is from around 15 degrees celsius to negative 45 to 50 celsius at the top
The temperature of the stratosphere actually gets warmer with elevation and ranges from minus 45 to 50 degrees celsius at the bottom to 0 degrees celsius at the top.
The mesosphere is similar to the troposphere and the temperature decreases with elevation.
The temperature ranges from 0 degrees celsius to negative 90 degrees celsius at the top.
Finally, the thermosphere gets warmer with elevation. The temperature ranges from negative 90 degrees at the bottom to over 1500 degrees celsius at the very top

As you move from the troposphere to the thermosphere the atmospheric pressure decreases.
As you go up in elevation the atmospheric pressure decreases and as you down in elevation the atmospheric pressure increases.
In 2012 Felix Baumgartner completed a freefall parachute jump from the stratosphere. During this jump, he reached speeds of over 800 miles per hour and broke the sound barrier. He was able to reach speed because the atmospheric is so thin there was very little friction to slow him down.

Learn about dice probability. How do you calculate the probability of rolling an 8 with a pair of dice?
You can calculate the probability of rolling a number by using the number of favorable events divided by the number of total events.

Learn all about three main types of rocks.
Igneous rocks are born of fire
Sedimentary rocks can be created from weathering then erosion along with deposition then compaction and cementation. During weathering small bits of rocks are created called clasts.
