Why do we have sunny weather one day and heavy rain the next? Large air masses cause some of our weather. There are four main fronts caused by these air masses.
A cold front which is the result of cold air
A warm front which is caused by warm air rising over cold air.
An occluded front which is a warm air mass stuck between two air masses.
A stationary front which is two air masses with almost the same density and pushes against each other.

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.

How we digest our food.
Digestion begins in the mouth. Your teeth chew the food and saliva is added.
From the mouth, the food travels down the esophagus to the stomach.
At the stomach, the hydrochloric acid helps break down the food into chyme.
From the stomach, the liquid chyme travels to the small intestine where the liver and gallbladder add bile and the pancreas adds enzymes.
From the small intestine, the food travels to the large intestine and then the rectum.

Seahorses are really cool fish. They have a head that looks like a horse, a tail that wraps around objects and armour. Another really interesting fact is that the male gives birth.

Learn how to find the square root of 64. I like to use a factor tree in order to find all of the prime factors. Then you can pull out pairs of numbers and multiply them together.

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

Hurricanes also called tropical cyclones are amazing, powerful storms that can bring destruction and misery to an area hit by the hurricane. The Congressional Budget Office estimates that 1.2 million Americans live in coastal areas at risk of “substantial damage” from hurricanes
In this video I will look at the causes these tremendous storms?
In the northern hemisphere most hurricanes will begin to form around the equator off the coast of west africa.
The official hurricane season is between June 1 and November 3o
Why do hurricanes occur during this time period.?
The reason is that hurricanes need the ocean surface temperature to be at least 79-degree Fahrenheit.
In addition, you need high pressure above the hurricane and low wind shear.
Between June and November both of these conditions are meet often
Hurricanes are like giant engines that use warm, moist air as fuel. That is why they form over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. As the warm air rises a low-pressure system is created.
Air from surrounding areas with higher air pressure pushes into the low-pressure area. Then that "new" air becomes warm and moist and rises, too. As the warmed, moist air rises and cools off, the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean's heat and water evaporating from the surface
Tradewinds which blow across the equator help push the storm along.
The hurricane will rotate in an in a counterclockwise fashion in the north due to the Coriolis effect.
The Coriolis effect is caused by the earth's rotation and curves air in the northern hemisphere to the right.
The hurricane will continue to move across the ocean and pick up strength if the water temperature remains above 79 degrees, high pressure remains above the storm, and there is moisture to fuel the storm.
Hurricane strength is measured by wind speed and barometric pressure.
The minimum wind speed to be classified as a hurricane is 74 degrees and category 5 hurricanes have a wind speed greater than 157 miles per hour.
As a general guideline, September is the peak month for hurricanes because of the warm surface temperatures during this month.

Learn what the square root of 5 is, plus how to simplify the square root and the decimal value. I also review how to estimate the square root of 5. I like to use a factor tree when simplifying a radical.

The nucleolus is a region in the nucleus that contains RNA. See this dark spot in the onion cell? That is the nucleus, one of the few organelles you can see with an inexpensive microscope. If you look carefully at the nucleus you may see a dark spot. This is the nucleolus and it is found in eukaryotic cells.
What is the function of the nucleolus?
It has been described as the brain of the nucleus and contains RNA.

The path of food through the digestive system.
Digestion starts at the mouth, travels down the esophagus, enters the stomach, passes through the small intestine, and then the colon. Along the way fats are broken down, sugars are converted, and important nutrients are absorbed by villi and transported by capillaries.

00:00 Introduction to the digestive system
00:30 Digestion begins in the mouth
1:07 Food travels to the stomach
1:31 Enzymes and Bile are added at the small intestine
2:39 Nutrients are absorbed in the small intestine
2:59 Finally water and fats are absorbed at the large intestine

Saprotroph and detrivore are important decomposers that help recycle organic matter.
Saprotrophs include bacteria and fungi. These biotic factors release enzymes that break down the detritus.
Detritivores must ingest the decaying matter before decomposing it.
Both of these decomposers help recycle nutrients in an ecosystem.

Study Tips for the visual learner.
Are you are visual learner?
Do you prefer pictures instead of written directions?
As the teacher is lecturing do you create pictures in your mind?
You may be a visual learner.
In this video I suggest several tips help a visual learner at school

Heterotrophs vs Autotrophs An autotroph is also called a producer and a heterotroph is called a consumer.
A heterotroph is an organism that cannot practice photosynthesis and must consume other organisms for energy
An autotroph practices photosynthesis.

How do ecosystems change over time?
Ecological succession, also called Biological succession occurs when one ecological community changes into another.
There are two main types of ecological succession.
Primary and Secondary Succession.
Primary Succession occurs when there is no soil and the new community has to start without any soil.
Secondary succession occurs when an event destroys an area but the soil remains.
The pioneer species are the first plants to appear in the new ecosystem.

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.

Erosion happens when rocks and sediment are picked up and moved to another place by water, pause wind pause ice pause and even gravity
Erosion can occur slowly over time like a sand dune or quickly like a flood
There several methods of erosion.
Remember, weathering breaks down the rock, and erosion moves the rock away
Rainfall can cause erosion and wash sediment away
Valley erosion occurs when rushing streams and rivers move rocks and sediment downstream
Oceans are a huge force of erosion
The wind is can cause erosion
A dust storm can be a huge force of erosion
