The tropical rainforest is located around the equator and is hot, humid, and receives much rainfall.

This video is about the Law of Superposition and includes a demo to help with understanding.
The law of superposition is that the youngest rock is always on top and the oldest rock is always on the bottom. so the relative ages came to be arranged by the depth of the rocks.

The Earth is 70 % water. However, only 3% of this water is freshwater. Much of this freshwater is frozen in glaciers, you will find some of the water in rivers and streams, and almost 30% of this freshwater is groundwater.
But What is groundwater? Groundwater is water that finds it way between the gaps of rocks and sediments underground.
As the water seeps into the ground it may find it’s way into an aquifer. Aquifers are underground rock layers saturated with groundwater. An aquifer is not an underground river but large porous layers of rock.

Learn how to create a dichotomous key. A dichotomous key is a method to identify objects like animals, rocks, trees, plants, and many other objects. In this video, I use monsters in order to show you how to create a simple dichotomous key. Dichotomous means two parts so the key uses two questions at each step. There are different types of dichotomous keys but in this video I show you how to make a simple key.

Learn how to solve 60% of 40 and other percent problems. I solve the following percent of problems.
20% of 60
20% of 40
15% of 40
15% of 60

What is Carrying Capacity? The carrying capacity is the maximum number of a species that an environment can support.

The maximum number of individuals in a species that an environment can support for the long term is the carrying capacity. Carrying capacity is limited by the limiting factors. These factors may include food, water, shelter, appropriate space, as well as disease, predation, and climatic conditions
If a population nears the carrying capacity. resources become limited and if a population exceeds the carrying capacity deaths began to outnumber births

If you live in the united states,canada, or Australia, you use a 12 hour system for telling time.
If you look at this clock it is 7 oclock. However is this 7 oclock in the morning or 7 oclock at night. This is where am and pm help
.The 12-hour system divides the 24 hours of a day into two periods lasting 12 hours each. The first 12-hour period is designated as am. It runs from midnight to noon. The second period, marked pm, covers the 12 hours from noon to midnight.
AM comes from the latin phrase ante meridiem, which translates to, before midday)
and p.m. from the Latin phrase post meridiem which translates to, past midday
There are 24 hours in a day, this requires the hour hand to pass the 12 twice.

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.

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.

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

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.

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.

Running experts all agree that an efficient runner lands on their forefoot.

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.

Nervous System controls the human body by sending electrical signal through out your body.
The nervous system can be divided into the central nervous system and the peripheral nervous system.

The spleen is located in the upper left abdominal cavity, just beneath the diaphragm, and next to the stomach. It is similar to a lymph node in shape and structure but it is much larger.
An easy way to remember the anatomy of the spleen is the 1×3×5×7×9×11 rule. The spleen is 1" by 3" by 5", weighs approximately 7 oz, and lies between the 9th and 11th ribs on the left-hand side.
Your spleen is considered part of the lymphatic system.

the spleen consists of two types of tissue called white pulp and red pulp. The white pulp is lymphatic tissue consisting mainly of lymphocytes around arteries. The red pulp consists of sinuses filled with blood and lymphatic cells,

As blood is filtered through the spleen old and damaged red blood cells are removed from the blood. In addition, the spleen produces lymphocytes in response to invading pathogens found in the blood. The spleen is like a large lymph node that filters blood instead of lymph looking for invaders like harmful bacteria. White blood cells stored in the spleen help remove and eliminate these invaders. It is particularly helpful when fighting meningitis and pneumonia

The spleen also stores blood. The sinuses in the red pulp of the spleen are filled with blood and can be used in case of an emergency.

You can live without your spleen. your immune system won’t shut down without a spleen, but it won’t operate as efficiently.

The sodium-potassium pump is a type of active transport that moves 3 sodium ions into the cell and 2 potassium ions out of the cell. I cover why the pump is needed and provides an overview of this type of active transport cells use to move important objects into and out of the cell.
ATP is used to change the shape of the carrier protein allowing the sodium and potassium to move across te cell membrane.

In this video I cover what causes the ocean to have tides. The gravitational pull of the moon and sun cause tides. Spring tides occur when the sun and moon line up and Neap tides occur during 1st and 3rd quarter.
