Capacity(237)

Let’s pretend that cylinder above is an empty bucket. This bucket can hold 1 gallon of water maximum. It can also hold 4 quarts, 3 liters, 3000 milliliters, 8 pints, 16 cups, 32 tablespoons, and 64 teaspoons of water. These amounts are all equal 1 gallon in different units of measuring fluids. They all take up a capacity of water that bucket can hold.

Weight(238)

Weight is similar to capacity in terms of measurement. The units of measure in any sense from smallest to largest are milligram, gram, ounces, pounds, kilograms, and tons. These measurements measure the weight of something to a scale. A scale is a tool used to find the weight of something. 1 milligram is as light as a sesame seed. A very sensitive scale is needed to measure things in milligrams. A gram can be the weight of a peanut. An ounce is very close to a gram. A big apple can equal one pound. A kilogram can be the weight of a 2 inch block of solid metal, and a ton can be the weight of a pick-up truck.

Distance(239)

The measure of a distance from point A to point B can be in millimeters, centimeters, inches, decimeters, feet, yards, meters, kilometers, and miles. A huge distance is calculated using miles or kilometers, a local distance can be calculated in meters. Any close distances can be calculated in yards and feet. Any very short distances are calculated in decimeters, inches, centimeters, and millimeters. Rulers have these labeled measurements from a millimeter to a meter. You can measure the length of a pencil with a ruler if needed to.

Time(240)

Time can be measured in seconds, minutes, hours, days, weeks, months, and years. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, 7 days in a week, around 4 weeks a month, and 12 months in one year.

all in one brain teaser number 1: Water Consumption(241)

We can include all the different units of measure in one word problem. This kid named Kevin drank a certain amount bottles of water overtime daily. Those bottles were half a liter (500 ml), with a weight of 1.25 pounds and a measure of 8 inches filled up to the top (.07 pounds of that water is the plastic with the bottle cap). He drank half of that bottle at 2:56 p.m. to take a 230 milligrams of a single vitamin C pill. The amount of water decreased to a measure of 2 inches inside the bottle 1 hour and 47 minutes later when Kevin got thirsty. Kevin drinks 2 inches of water every hour and 47 minutes during the day after school. He drinks a whole water bottle in the morning before school at 7:00 a.m, 35 minutes after he wakes up every day. He went 10 hours and 53 minutes without drinking water overnight. He went to sleep 35 minutes after he had his last sip of water yesterday. He drinks 200 ml. water at school at lunch at about 12:30. The water Kevin drinks is a repetitive daily process.

Purpose of brain teasers(242)

That brain teaser I came up with is hard, even for me to solve. It’s hard because its teasing our brain, literally. A brain teaser has so much information in a paragraph or two to solve 20 problems. You need to stay calm and just read the questions over and over until you can uncover the tease or trick in the problem. Brain teasers help you by practicing taking baby steps to answer a question. You can think all you want mentally, but you won’t get the answer until you break the question down into parts, referring to the given information.

Chapter 11: Problems people face in life

Problems (243)

Problems and mistakes always happen in someone’s life even if the person is perfect and not causing problems. Some problems can be…

Fears/phobia’s(244)

A fear (phobia) is something a person is scared of that someone else is not scared of. A person can’t climb up a mountain because they might be scared of heights. A person can’t go outside in the dark because they might be scared of the dark. These are some common fears a person has. A fear of being in a tiny room filled with people is called claustrophobia. Notice the suffix phobia in that word, which means fear.

Robbers/burglers(245)

Nobody knows when their house will be robbed or not. Robbers are criminals that break into people’s homes and steal money and jewelry and any precious items. They do this overnight while people who are unaware of what’s happening are sleeping. Robbers and burglars are smarter than they look. They have go through a lot of clever thinking to rod and burglarize a house. A trick they can pull can be putting an egg under a mat near the front door. If the egg breaks overtime, the person left the house.

Police(246)

The police can turn a person’s day upside down. A person is speeding down a highway and is in a rush. Suddenly a police car is racing on his tail. He has to pull over. The police officer will right up a speeding for about 50 bucks and call it a day. The police officer doesn’t care, but you do. The police is a problem in certain people’s lives’. If a person has a warrant for their arrest, they have to be especially sneaky in the city because they are wanted by the police.

School(247)

School can be a problem for students who face not willing to be educated. School is a required thing kids take over the course of 12 years. School can be a pain for every student who doesn’t care about education. I actually like school and think it’s fun, but others think school is a bunch of wasted time.

Planning(248)

Every single person has a plan for what to do every day. Whether its staying home and relaxing or going to work, you have a plan. Planning a day is scheduling certain things to do in that day. When you think times runs slowly, you have nothing time consuming to do. When you have been busy all day, you think time runs fast. Planning a day is hard work for a busy day because you will have a tight schedule. This is when you plan something accordingly.

Divorce(249)

A divorce is a split of a married couple overtime. A divorce is not a good thing because two families that was initially together are split. A child of divorced parents lives either with his biological mom and dad alternatively. This makes the child cry and say that doesn’t want a step-mom. He wants to wish that his mother and father will get back together sometime, but they won’t. When two people sign a divorce contract, they can’t be re-married unless they promise not to divorce again.

Jealousy(250)

When a person is jealous of someone that means he wants what that kid has. A person can be jealous of somebody else when he is better than you, visually. Jealousy is a word to describe a feeling in a person when he wants what someone has. It can be an A on a test, a girl or boy friend, a box of chocolate, the car he has, the care and respect he gets etc. When you are jealous, you try to get what the other person has that you don’t.

Raising a child(251)

In reference to paragraph 7 is is a problem parents face after birth of a baby. They put their lives in their child’s hands because whatever they do to the baby, the baby will more than likely do what the parents did to him. Raising a child is called parenting. Parenting is when parents explain what a child did wrong when he gets punished for whatever reason.

Giving up a child (252)

In reference to paragraph 251 and 7, a parent has to raise a child. If in some cases a parent does not want or know how to raise a baby, they give up the child. This process is called adoption. A child is given different people to raise him when he is adopted. He gets different parents without understanding at a young age that they are not his biological parents. I feel its just horrible to get adopted at any age, actually.

Orphans (253)

Orphans can be any person without a mother or father. They might have died a few days after a Childs birth, or even when their child is 65, the child will be an orphan. Being a young orphan is a big problem in certain people’s lives. Theseorphans have no one to be with, so they are reported to an orphanage. They might be given foster parents, or parents that adopted orphans. I can’t imagine that a baby did not get a chance to get to know his own parents. This is just a tragedy, not a problem that lasts for life.

Arguments(254)

Arguments happen almost every single day to a person. An argument is a disagreement between 2 or more people when they start explaining their side of the story. Nobody really wants to argue, but arguments happen when 2 people have different thoughts about a dilemma. A dilemma is a 2-sided arguable problem or situation. Huge arguments end the person who started in the court room. He can even go on to jail if it’s too much of an argument.

Technical difficulties(255)

A person gets annoyed when they sent a bunch of information on a computer and the computer freezes. Now they have to resend that information all over again. This is a pain for people with slow and old computers. Pop-up messages are annoying and cause problems or just slow you down. People use computers to speed things, not slow things down. Another technical difficulty can be a flickering light bulb when it’s over loaded, in reference to paragraph 138-140.

Work (256)

Work is a little too much for a person who works a lot in a full-time job. On the other hand, working has a benefit, earning money (paragraph 17). People earn money for working, but work can be a pain a working person can face.

Illnesses (257)

People are prone to get illnesses through their life time. In reference to paragraph 24, people at a certain age go to the hospital for operations or surgery. Both can fix a person’s internal health. An allergy (paragraph 105) is a specific type of illness a person has through birth. Illnesses like this stick around for quite a while with treatments and possible cures.

Chapter 12: Family Identification

Families (258)

Everybody, dead or alive, has a group in which they genetically belong to. That group is called a family. A family is an expansive group of genetically equal people who care for each other. When a baby is born (paragraph 5), he is born genetically equal to his parents. Since the 2 parents brought this baby to the world, the baby has inherited some of his parents' traits, characteristics, and genes (paragraph 181).

Brothers and sisters (259)

Brothers (male) and sisters (female) are related in a family. A brother is a male that was born from the same mother that already gave birth to a boy and/or a girl. A sister is a female that was born from the same mother that already gave birth to a girl and/or a boy. These family names are biological, meaning there from their birth parents.

Uncles and Aunts (260)

An uncle is your mothers or fathers biological brother. An Aunt is your mother or fathers biological sister. If you are an uncle or aunt and your brother or sister have kids, their kids are your nephews or nieces (boy, girl).

Grandparents (261)

A grandparent is your mom or dad’s parents. Your grandfather is your mom or dad’s dad. Your grandmother is your mom or dad’s mom.

Great grandparents/ancestors (262)

The farthest and oldest of family relations are (if possible) great grandparents. Our great grandparent is the mom or dad of your grandparents. Once a great grandparent dies, there are known as ancestors to our family. An ancestor is a person who once lived in relation to family and passed away way before. Families extend all the way to Adam & Eve (paragraph 154), which are our true parents, like god.

Family tree (263)

In paragraphs 258-262, I talked about family relations. These family relations are formed in a diagram called a Family tree. It’s quite confusing for me to actually draw out the diagram because families are so extensive and sort of mixed up into family clusters. When I say clusters, I mean different locations.

Distant families (264)

I can bet that all families are not all together in one big cluster within a 10 mile radius. A family will be located most likely in a different country. Let’s use my family as an example. My family in the most general way possible speaks almost 4 different languages. My family speaks American, Russian, Italian and some Ukrainian. This means they were born and raised in any of those countries that speak those languages.

Mother’s side of the family (265)

My mother takes up about half of my family tree with her side of the family to conjoin with mine. My mother is from Russia with 2 of her biological brothers and her mother. These are the closest related people in my mother’s side of the family. One of her brothers has a wife with a 3 year old girl. The wife of my mother brother will be my mother’s step-sister, and the little girl will be her niece or aunt, depending on how you put it. My mother’s father is now an ancestor because he passed away.

Father’s side of the family (266)

My father was born in Italy with his family. When I was born, his family conjoined to my family and my mother’s family all together. My dad has a number of brothers and sisters all in Italy. Those brothers and sisters are my aunt’s and uncle’s. I don’t know most of my father’s family because I don’t go to Italy as often as Russia, which I go to every year.

Last names (267)

Every person has a last name, or family name. Your last name is carried from your mom to dad, from your grandparents of your father’s side of the family. Your last name is inherited from your father’s side of the family because he is the one who passed his last name to my mom because he married her. It’s a traditional America way of marrying; carrying the husband’s last name to the wife once they are pronounced man and wife. The same last name continues its way down the family tree until a girl is born and will be married.

In-laws (268)

When there is a marriage, the two people conjoin families. The In-laws of the whole family to the wife are her husband’s family and parents, and vice versa for the husbands perspective. They are called in-laws because the wife now carries the husbands last, which makes her non-biological family from her husband a legal family, otherwise in-laws.

The same name in a family (269)

In some cases its tradition for a boy to carry the same name as his male ancestors due to a historic event or token of memory. The youngest person with the same name has his great grandfather will be the great grandfathers name and junior (jr). Junior means youngest person to carry an equal first and last name. After junior, roman numerals express the same name. The first would be the person who first had this name in the family and etc.

Middle names (270)

Most people in the world carry a middle name. It is the parents’ decision if the baby will carry a middle name or not. The middle name is usually the baby’s grandfather’s name in most cultures.

Identifying people (271)

People are identified mostly by their first name. Friends and family call a person by their first name. If you are talking an adult older than you, you call him Mister or sir, or if it’s a lady Miss or Mistress (Mrs). A mistress is a married lady. If you talk to a police officer, you would call him officer followed by his first or last name. If you are speaking to a judge, you would say your honor or judge followed by his last name.

Chapter 13: General Identifications

People’s legal identifications (272)

Every person in America who is over 18 has a legal identification. That is called a person’s ID, or symbol of legal identification. That is a card that a person has to carry everywhere he goes. It has his full birth name and other personnel information along with his birth day and current residence with his zip code and street address. This little card is you in words basically.

Social Security (273)

Every person in the united states has a social security number. Social security numbers are private codes that open a person’s police records and medical information or even there jobs information. Even a little kid has a social security number. This number is only used to apply for insurance and store credit cards etc.

School ID (274)

Every student has student identification. They have a certain lunch card number that identifies them they are not trespassing. On a major test, their scores get reported to the state via their test state identification number.

Passwords (275)

A password helps protect your own information in any computer. Before you log into a computer, it asks you for your password protected user account. You type in the password symbolized by black dots, and you log on. Every e-mail has a password to make sure you and only you sees your private e-mails. Passwords are basically security codes in machines that help protect other information THAN YOUR SOCIAL SECURITY.

Keys and locks (276)

Keys are used to secure private property. A key is a metal carving with a head and a pointy tip. You stick in the tip of the key to unlock a lock in its keyhole. Each and every key has a different carving along its tip unless it unlocks the same door. A key can be the same if you make a copy of it at a hardware store. All keys unlock doors and locks. A lock is a thing with an unlock able metal U-shaped strap along the top of the keyhole. Locks can even be password or number protected with a number or letter dial.

License plates (277)

Every car has a license plate in the front and/or back of the car. A car without a license plate is not a car, so every car has one or two of these plates. These plates have various numbers of numbers and letters ranging from a single number or letter, to 7 or 8. If the person driving a car is certified for a handicap parking spot, a license plate might have a handicap symbol followed by various numbers and letters. A license plate identifies a car to the state and country.

Highly protected identities (278)

Not everybody can waltz in a world trade center and steal the states money. A world trade center is a highly secured facility where certain people can walk in. Even they must be tested before walking in to their job. They have various key cards that they swipe to open hard metal doors throughout the building. An airport also has security, and lots of it. Before going any were in an airport, you must pass security tests. An airport has nothing much important to protect unlike the World trade center, but it still is protected.

Passports (279)

The most important document every bilingual person has is their passport(s). A passport is a legal identification of allowing you to be in a certain country for an unlimited time. Once a child is about to immigrate to some other country, he needs to format his passport or visa. A visa is like a limited passport for a short time in order to go to an unfamiliar country for a short time. Anybody in the United States who is a resident and goes to work has an America or United States passport. Passports are checked every time you leave from and go to a different country.

Reformatting passports (280)

Passports will come to you with expiration dates. You have to reformat (update) your passport every few years depending on how much you have changed generally. You would need a new passport picture to be renewed so airport security will know its really you according to our legal faces in a passport.

Reformatting international passports (281)

In paragraph 280, I talked about reformatting passports to your own country. If you reformat international passports in a country other than the passports country, you need to make a visit to your countries embassy in your current country. An embassy is a building where people from your reformatted passports country reformat your passport according to their laws. You must go to your countries embassy to solve international problems in a different country.

Bar codes (282)

Every item that is trying to be sold at a grocery store has a bar code. That bar code has dark and light lines followed by numbers along the bottom. Before actual pu8rchasing an item, the sales person scans that code with a bar code reader or converter. That bar code identifies what the item is and how much it costs.

Delivery codes (283)

Before mailing out a package, the delivery guy has to know where it is exactly going. To label where your sending that package, you go to the post office or company you are sending it to to get a label. A label is a sticky piece of paper you put on a box before it gets shipped. It includes the address and postal code of the area its getting delivered to. A bar code is found on the label so that the post office can track down the package if it gets misplaced. It gets recorded on the computer. The post office will also charge you with a fee for shipping the package according to mileage.

Chapter 14: Computer Technology

Technical benefits (284)

As you may already know from paragraph 116, computers are a big help for us to go through life. That was just a quick general paragraph to introduce computers, but there is way more to talk about that in the computer world.

CPU (285)

A CPU stands for Computer Program Unit. This is the central part of a computer system coming to life. CPU’s are only in desktop computers, not laptops. The CPU is the box shaped thing that you turn on a computer and plug things into it from the back side.

Components (286)

Whatever you plug into your CPU is a component except for the computers plug. All pluggable components have a wire that connects them from the device to the computer. Most components are not plugged into an electric outlet because they are powered from the computers central plug-in unit.

Mouse Component (287)

A mouse is a lot like its real meaning, a thing with a tail scurrying all over the place. A mouse component is connected to the computer, not an outlet. You maneuver the mouse to click on items on the computer screen once it is on. A mouse navigates your hand virtually with two clickers on each side, right and left. The left clicker is the main clicker to open and press virtual buttons on the computer screen. The right clicker is clicked to read internal information of a desktop icon (talk about this stuff later).

Battery powered mice (288)

In reference to paragraph 134, batteries can also power objects, like a computer mouse. You won’t have to plug in a battery powered mouse to a computer. You just have to put in a tiny pluggable micro-chip into the CPU to indicate that the mouse is being used on this CPU. It functions the same way as a component mouse with a difference in power consumption.

Other parts of a mouse (289)

A mouse has to somehow be able to detect motion of your hand in along with its velocity. An old fashioned mouse has a little ball on the bottom that rolls in place to sense motion. A newer mouse would have a sensor indicated by a light on the bottom of it to detect motion. If the light is off, that means the mouse is not responsive to the computer, meaning it is off.

Keyboard components (290)

Every desktop CPU has a keyboard. A keyboard has various buttons you press with numbers, letters, and symbols. Whatever character you press, that character will appear on a typing bar on your desktop. A character is any button on a keyboard, including the space bar that makes spaces in a computer made sentence. A keyboard is no toy because it has commands that can actually mess up our system.

Keyboards set-up (291)

A keyboard has a certain set-up. The letter characters are in the center of the keyboard bearing a little bit to the left side. The alphabet is not accurately set-up in a proper letter sequence. Instead of the first letter being A on the keyboard, the letter is Q followed by W,E,R,T,Y,U,I,O,P,A,S,D,F,G,H,J,K,L,Z,X,C,V,B,N,and M. This is not in the ABCD format obviously. Letters Q to P are on the top row, letters A to L are in the middle row, and letters Z to M are on the bottom row of the letter part of the keyboard.

Shift keys and functions (292)

A keyboard has two shift, alt, and control keys that do functions to the computer. A shift key can unlock secondary keyboard characters by pressing any shift key with the key. Some keys on the keyboard have two symbols with one being smaller than the main key. The shift key allows you to use those smaller symbols on a desktop. The shift key makes the lower case letters on the letter board upper case letters. The Caps lock key will make the letters LIKE THIS without pressing the shift key.

Monitor Component (293)

The monitor component of a CPU is a screen that lights up your desktop. Monitors have two plugs, one goes into an electric outlet, and goes into the CPU. You use a mouse and a keyboard thanks to the monitor.

Managing Monitors (294)

There are buttons on a computer monitor below or on the side of the screen. You adjust the monitors contrast, resolution, brightness etc. The contrast of a monitor is the depth of the monitor’s pixel light. Pixels light up a certain way in a monitor on a specific contrast level. The contrast is kept at 50% originally. The resolution of a monitor does margins to the screen of the computer. Black spaces represent margins of a screen resolution. A high definition monitor has extensive resolution and pixel light. The monitors brightness calibrates the pixel light and how they stand out. Its barely possible to see if a monitor has 100% brightness, and the monitor will be black if brightness is 0%. The brightness level is kept between 30 to 70% originally.
