In this math lesson, you will learn how to tell time on an analog clock. In this lesson, we will focus on reading the short or hour hand and the long minute hand.
We will learn three easy steps to tell time.
Start at the small hand
Write two dots
Read the large hand.

An organ is a group of two or more tissue that works together to complete a common function.
Your body has around 78 organs.
In this video, I will cover several major organs.

The brain is the boss of your body. It runs the show and controls just about everything you do, even when you're asleep

The heart is a very strong muscle made of cardiac muscle that helps pump your blood throughout your body.

The kidneys are very important because they filter your blood and produce urine.

The spleen filters blood and acts like disease detectives. It also produces antibodies and lymphocytes which fight germs.

The Small and Large intestines are a major site of digestion. The small intestine is responsible for 90 percent of digestion. At the same time, the large intestines absorb salts, mineral, and vitamins.

The Liver Is a large organ with over 200 functions. It produces bile which helps with digestion, stores glycogen, and filters your blood to eliminate harmful bacteria and damaged cells.

The gallbladder stores the bile produced by the liver

Your stomach Is a site of digestion of the food we eat. After chewing our food it travels down the esophagus to the stomach.

The pancreas helps to regulate the blood sugar level of your body.

The skin protects us from disease,removes waste, and helps control our temperature.


Finally, the Lungs are responsible for exchanging oxygen for carbon dioxide

How are concave and convex lenses different?
A convex lens is thicker in the middle compared to the edges. It is also called a converging lens because the rays and bent together. A convex lens is also called a positive lens because of the location of the focal point.
A concave lens is thinner in the middle compared to the edges.
It is called a diverging lens because the rays of light spread out.
A concave lens also is called a negative lens because the focal point is behind the lens.

Learn which type of graph is best four your data. A line graph is helpful for data over time, and a bar graph is helpful for categories. This helps you decide which graph is best for data visualization and which type of graph to use.

Equivalent Fractions look different but measure the same thing! I place several equivalent fractions on a number line in order to help you see that they measure the same things. Remember, a fraction measures parts of a whole.

Mountains can form through folding, volcanism, and faulting.
Folded mountains form when rock layers are squeezed together and are pushed upward.
Many folded mountains occur at convergent boundaries where continental crust collide
The Himalayas stretch through the borders of China, Nepal, India, and Pakistan is the most towering mountain range on Earth,
Volcanic mountains are created when melted rock erupts onto the earth’s surface. Many volcanic mountains occur at convergent boundaries. Most of the active volcanoes on earth are concentrated around the edge of the pacific ocean.
Fault block mountains form when tension causes the lithosphere to break into normal faults.
At normal faults, the lithosphere drops down. The pieces left standing form fault-block mountains.

How do thunderstorms form? In this video, I will cover the basics of these exciting storms.Here is how a thunderstorm forms
Step 1 Warm moist air is heated and begins to rise upward.
Step 2 As this warm air rises it begins to cool, condenses and begins to form clouds
Step 3 This warm air will continue to rise and will encounter cold air which will cool the moisture in the clouds and ice may form
Step 4 Eventually the cooled moisture and ice will begin to fall to the earth This action creates a downdraft
5. The updrafts continue feeding warm humid air and the falling moisture create downdrafts. This creates convection currents. You can see what convection currents look like. The warm water is in red and the cool water is blue.
These convection currents create the most violent stage of the thunderstorm
Lightning and strong winds are produced
6. Eventually the downdrafts will stop the updrafts of warm air
7 When the warm moist air is cut off the storm begins to dye off

There are three main types of thunderstorms; orographic, air mass, and frontal.

The structure and function of the small intestines. This coiled organ which is part of the digestive system is found roughly behind your belly button.
How large is the small intestine? About 22 or 23 feet long.
The intestines are divided into 3 parts. The duodenum, the jejunum, and the ileum
The small intestines also contain hairlike projections called villi that help absorb nutrients

Anaerobic Respiration Fermentation

Anaerobic respiration, also called fermentation, occurs when cells need energy but there is no oxygen for aerobic respiration. As a result, cells convert glucose into either ethanol or lactic acid.
Alcoholic respiration occurs in plants and yeast.
Lactic acid fermentation occurs in animals.

Acceleration is the measure of the change in velocity over time. The change in velocity can be a change in speed, direction or both.

The formula for average acceleration is
Final velocity-Initial Velocity over Time it takes to change

Acceleration is expressed in meters per second squared

Mesozoic EraIn this video I would like to talk about the Mesozoic era on the geologic time scale.
The Mesozoic era is part of the Phanerozoic Eon along with the Paleozoic and Cenozoic eras.
Mesozoic means “middle animals” and is a time of rapid change.
This era has also been called the age of reptiles and age of dinosaurs
The Mesozoic era was roughly 65 million years to 250 million years ago.
Let’s hit several highlights of this era
The Mesozoic era began after a mass extinction.
The shape of the continents looked different. At the beginning of this era, there was a super
Continent called Pangea. Over time this supercontinent broke apart and the continents started drifting apart.
The climate was warmer than today
The first mammals appear but are very small and they don’t begin to thrive until the Cenozoic era.
Dinosaurs also appear and begin to scatter and prosper.
The dinosaur population peaks during this era.
However, at the end of this era, the dinosaurs die off
The first birds appear and begin to scatter throughout the world.
The dominant plant is a cone-bearing tree and plants
At the end of this era, flowering plants begin to appear
So there we go the Mesozoic era,
Dinosaurs and cone-bearing plants
