Types of Galaxies in the Universe Teacherflix 4 مناظر • پہلے 2 سال

There are four main classifications of galaxies

Elliptical galaxies which are featureless and spiracle.

Spiral these have arms that spiral outward

Lenticular galaxies are given the symbol S0. These galaxies consist of a bright central bulge, similar in appearance to an elliptical galaxy, surrounded by an extended, disk-like structure.

Irregular galaxies are any other galaxy

What are the outer Planets? Teacherflix 4 مناظر • پہلے 2 سال

The gas giants which are also called the Jovian planets include the planets, Jupiter, Saturn, Uranus, and Neptune.
These planets are not only huge but have no real surface, are composed of hydrogen and helium, and revolve around the Sun slowly.
These planets also have rings and many moons that revolve around them.

All About Food Webs Teacherflix 4 مناظر • پہلے 2 سال

Food webs are diagrams that depict the transfer of energy in an ecosystem. In this video, I explain a food web using the real-life diet of an owl.
Many times in Science classes you may dissect an owl pellet to see what the diet of the owl consists of.
Owls consume rodents and small birds. The energy of these animals is transferred to the owl. Therefore, on the food web, you will see the arrows pointing towards the owl.

History of the microscope Teacherflix 4 مناظر • پہلے 2 سال

In this video I would like to talk about the history of microscopes.During the 1590s, the two spectacle-makers, Hans and Zacharias Jansen began experimenting. They put lenses in a tube and made a very important discovery. They discovered that objects near the end of the tube appeared to be enlarged, much larger than any simple magnifying glass could achieve alone.

In the 1660’s Robert Hooke began looking at all kinds of objects with his microscope.
He put all of his drawings in a book called Micrographia
He is credited with naming cells but also studied items like fleas under his microscope.
Anton van Leeuwenhoek was very good at grinding and polishing lenses.
These lenses led to the building of his microscope which was considered the first practical microscope.
In 1674 Anton Van Leeuwenhoek was the first to see and describe bacteria.
Another huge advance in microscopes didn’t occur until German physicist Ernst Ruska and the electrical engineer Max Knoll constructed the prototype electron microscope in 1931, capable of four-hundred-power magnification.
Electron microscopes uses accelerated electrons in order to view objects.
Modern electron microscopes can magnify objects up to 10 million times

How to clone-How Dolly the sheep was cloned Teacherflix 4 مناظر • پہلے 2 سال

Steps for cloning an animal
How Dolly the sheep was cloned and what we learned.
20 years ago Dolly the step was cloned from two sheets.
Here is how they cloned this sheep.
First, they took cells from the udder of one sheep. They grew these cells in the lab.
Next, they took the egg from another sheep and removed the nucleus.
These stopped cells were fused together and inserted into a female sheep who gave birth.

Keywords: Cloning dolly dolly the sheep

How changes in temperature create ocean currents ( Ocean Stratification Demonstration) Teacherflix 4 مناظر • پہلے 2 سال

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

Physical Exercise for Brain Power Teacherflix 4 مناظر • پہلے 2 سال

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.

Why are cells so small? Teacherflix 4 مناظر • پہلے 2 سال

In this video, I use diffusion cubes to show why cells are so small. A small cell with a large surface area to volume ratio can efficiently move materials into the cell.

Diffusion is a type of passive transport that cells use in order to move materials like oxygen and carbon dioxide into and out of the cell.
A cell with a larger surface area to volume ratio is more efficient a moving material than a cell with a smaller ratio.

Here is my recipe for the diffusion blocks
gelatin
Ammonia
Phenolphthalein
If you soak the diffusion cubes in vinegar then the phenolphthalein will turn pink when it comes in contact with the vinegar which allows you to see the rate of diffusion.

Practice Identifying Minerals Teacherflix 4 مناظر • پہلے 2 سال

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.

Three types of circulation in the body Teacherflix 4 مناظر • پہلے 2 سال

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.
