The ocean has many currents underneath the surface. One way these currents are created is by the difference in temperature of the water. Cold water is denser than warm or hot water and will flow underneath the warmer water.
This circulation of the ocean caused by changes in temperature is called Thermohaline circulation (THC)

Thermohaline circulation results as a result of differences in the density of the different temperatures of the water. These differences result in ocean stratification.


In this video, I use a container that is divided into two chambers to show how water flows.

Here are keywords you can use to order a similar container

Twenty or thirty minutes of exercise can make you increase your focus, motivation to learn, and improve your mood.
Regular exercise can increase these three neurotransmitters
In very simple terms dopamine impacts your level of motivation. Low levels of dopamine can result in low levels of motivation
High levels increase motivation.
Motivation is key to learning new material
Serotonin impacts your mood, anger, and depression. Low levels can lead to depression and higher levels can improve your mood which impacts your ability to learn

Norepinephrine naw·reh·puh·neh·fruhn impacts your ability to focus
Low levels led to dull focus, high levels sharpen your focus

20 or 30 minutes of aerobic exercise has been described as miracle gro for the brain.

So let’s apply this knowledge with a couple of suggestions to help you start brainstorming

Before your next study session get your heart rate elevated for 20 or 30 minutes then start studying

Take your flashcards on a brisk walk and memorize while walking

While studying take exercise breaks while you study. It could be as simple as dancing, or jumping jacks during the break.

Record your notes on your phone, put in your earbuds, go for a walk, and learn your notes.
The opportunities are endless, just combine 20 or 30 minutes of exercise with learning new material.

Use this video in order to practice identifying minerals. I have 7 minerals and I test their streak, hardness, color, magnetism, and luster.

I created this video to help you practice identifying minerals. Teachers, your students can practice identifying minerals with this video. I created a mineral guide, blank mineral guide, and an answer key. SORRY but I say rock instead of mineral a couple of times in the video.

Learn how to find the LCM (Least common multiple) using a factor tree.
The LCM is the smallest integer that two or more numbers divide evenly into.
For example, the lcm of 6 and 8 equals 24
In the video, I find the LCM for 16 and 24
LCM for 15 and 28
LCM for 30 12 8
A factor tree is a simple mathematical method to find all of the prime numbers of a specific number.
Once you know all of the prime numbers you multiply the prime numbers together and remove duplicates.
Once I know the factors of 6 and 8 I can easily find the least common multiple of 8 and 6.

Potential energy examples
In this video, I show examples of potential energy
Potential energy is stored energy.
I give examples of gravitational potential energy and examples of mechanical potential energy, and chemical potential energy.

In this video I will talk about three types of circulation found in the human body. lymphatic circulation and two types of blood circulation. Pulmonary circulation and systemic circulation.
Let’s look at blood circulation first.
Your blood is responsible for carrying oxygen, waste, sugar, and other important items throughout your body.
In order to carry oxygen and eliminate carbon dioxide it must travel to the lungs. Pulmonary circulation is when blood travels to the lungs and back. Blood enters the right atrium from the superior and inferior vena cava. It travels to the right ventricle and into the lungs through the pulmonary arteries. In the lungs oxygen is exchanged for carbon dioxide at tiny air sacs called alveoli and then returns to the heart through the pulmonary veins.
Up next is systemic circulation which is circulation throughout the body. As blood returns from the lungs it enters the left atrium then travels to the right ventricle then passes out the aorta and into the rest of the body. This circulation is called systemic circulation.
Three types of vessels are used for blood circulation.
An artery is a blood vessel that takes blood away from the heart to all parts of the body (tissues, lungs, etc). Most arteries carry oxygenated blood Arteries are usually shown as red vessels.
Veins are blood vessels that carry blood toward the heart. Most veins carry deoxygenated blood from the tissues back to the heart both of which carry oxygenated blood to the heart. Veins are usually shown as blood.
Capillaries are tiny vessels that connect arteries and veins.

The third type of circulation is called lymphatic circulation.
The lymphatic system absorbs and transports lymph. Lymph is a clear fluid that is a result of plasma leaking out of capillaries.As plasma moves out of capillaries, some of it is not reabsorbed. You lose around three liters of the plasma a day. The lymphatic system reabsorbs lose fluid.
If you look at this cross section of a tissue you can notice how the lymphatic vessel is located near the vein.
Once this plasma that has leaked out of capillaries and enters lymphatic vessels it is called lymph
Lymph also includes protein and cellular debris which are too large to be collected by veins and capillaries.

The lymphatic vessels have smooth muscle and valves that help move the lymph throughout your body.
