How meteorologists forecast weather (Weather Science Essay)

There are a few methods that meteorologists use in order to forecast the weather.

The first method we learned about was the Persistence Method. The persistence method is a way of predicting the weather, basically predicting tomorrow’s weather off of today’s. So, if it were sunny outside (which it isn’t where I live at the time of this essay) and it was 45 degrees, then I could say it would be the tomorrow. As simple as this method is, sometimes it comes off as a very unuseful method. It would be very useful in the summer somewhere south like Florida or South California, but it wouldn’t if it were mid-spring winter, or fall. Since weather patterns change so often, this method would be very useless in many situations.

The next method is Numerical Weather Predictions. This method uses complex computer programs to predict the weather based on temperature, pressure, wind, and rainfall. Since it relies on computer models, the atmosphere models are not accurate some of the time. This leads to errors in the prediction. Despite that, it is a very easy-to-use method.

Those were two of the few methods we learned about this week.

Wind (Weather Science Essay)

Wind is moving air (a.k.a. Air motion). It can be caused by three different sources:

Pressure Gradient Force

An effect where high pressure areas force air to lower pressure areas.

Coriolis Effect

An effect where the Earth’s rotation causes the air to turn.

Friction

The Earth’s friction causes the flow of the wind to slow down.

Winds in lower pressure areas are usually cold and rise, and the moisture from this eventually forms into clouds. Winds in higher pressure areas however, they are usually warm and sink, and fits it to the category that many people would consider good weather.

The Health Benefits of Dark Chocolate

So, chocolate. A thing that almost everyone loves. We all have our preferences when it comes  to anything, including chocolate. Whether you prefer Milk, Sweet, White, Bitter, Semi-sweet, or Bitter-sweet, there’s one type of chocolate that has its share. Dark chocolate. Now, I know what you’re thinking. “How can chocolate be healthy?” Well, dark chocolate has many health benefits, and it’s thanks  to the antioxidants from the cocoa tree. For the benefits, it lowers high blood pressure. Also, researchers found that epicatechin, a chemical in dark chocolate, can protect your brain after a stroke. It can also be used to treat anxiety and stress. It can also lower your risk of cardiovascular disease.

Fermentation in Cocoa Beans (Science Writing Assignment)

Fermentation in cocoa beans begins with the growth of micro-organisms, Yeast grows on the pulp surrounding the beans. Insects, like the vinegar fly, might be responsible for bringing micro-organisms to the beans. The yeast turns the sugar in the pulp to ethanol. Bacteria then starts to oxidize the ethanol; into acetic acid, and then into carbon dioxide and water. These chains of events ends up producing more heat and raises temperature for the beans. The length of fermentation varies depending on the bean type.

RPC Homeschool Week 6

ENGLISH

For English I wrote about Egypt:

HISTORY

For History, I wrote about more Egypt:

I think life and death was so important to Ancient Egyptians because:

Well, for pharaohs, Egyptians saw them as gods, so I think that they wanted the pharaoh’s spirit to keep maintaining in the afterlife, basically, making the pharaohs have a good after life. For people below pharaohs (citizens), I think it’s the same exact reason for pharaohs. The family members of that person would want them to have a good after life. Like I said before, I think Egyptians were obsessed over afterlives for pharaohs, again, because they saw them as gods.  For normal people, the wanted them to have a decent afterlife, so that’s why they gave civilians treatment for a good afterlife. They would usually bury chairs, food, gold, and treasure with tombs, so that the person inside the tomb could have an afterlife of goodness. The Egyptians put anything in the burial that would help that person live a good afterlife.

 

MATH

For math, I did a math exam.

 

SCIENCE

For Science, I started Plant Science.

RPC Homeschool Week 5

For Week 3 in RPC Homeschool, I continued do the regular, English, History, Math, and Science. Here’s what I did over the week.

English

I continued reading Hans Brinker or the Silver Skates. I also wrote a short essay based around Spring.

It was beautiful day in Spring. A brother and a sister were playing in the April Showers. They were splashing in the puddles that were slowly growing due to the heavy rain. Rains were the normal around April and May, and enjoying the warm breezes, the cold rain, the beautiful flowers, and the greenest, richest of grasses.

History

I wrote about Ancient Egypt.

Ancient Egypt was during sometime when Egypt was being developed. At first, Egypt was separated into two kingdoms. However, Pharaoh Menes ended up uniting the two kingdoms, making Egypt one whole kingdom. These chains of events make up the Old Kingdom, which only lasted the first 3-6 dynasties. The Egyptians started building pyramids for pharaohs, but the first true pyramid was built by Pharaoh Senefure. Most pharaohs were buried in the Valley of Kings, some were buried in tombs that were built with 6 layers: Mastaba first, then the other layers. There were 3 intermediate periods: The old kingdom. The second intermediate period, and the third intermediate period. The Second intermediate period lasted 14-17 dynasties, and the third lasted about 21-25 dynasties.

Math

We reviewed basics about division, division word problems, we also studied a bit on prime numbers.

-Science-

For Science, we studied glaciers, mountain ranges, and wind and desert erosion.

RPC Homeschool Week 3

For Week 3 in RPC Homeschool, I continued do the regular, English, History, Math, and Science. Here’s what I did over the week.

English

I finished doing the grammar section of my class, and went back on to the Literature side. I started Hans Brinker or the Silver Skates.

-History-

I finished the first World Tour for my class and started back to events from the Bible and such.

-Math-

We reviewed basics about multiplication, multiplication word problems, etc.

-Science-

We studied about volcanoes, and super volcanoes.


Hey everyone! Thanks for reading this review for last week’s homeschool! Sorry I didn’t do it earlier ¯\_ツ_/¯ I’ll be posting another review tomorrow (tomorrow is my review day, thanks to me doing Saturdays), so yeah! Have a nice day today!
