"The President Has Been Shot": The Assassination of John F. Kennedy by James L. Swanson

This book provides a comprehensive look at the events surrounding President Kennedy's assassination. The author gives you an up close and personal view into the relationships between the President and Mrs. Kennedy and the Secret Service agents while explaining how these relationships impacted the decisions that were made during and immediately following the assassination. At the same time, the author gives you insight into the mixed-up world of Lee Harvey Oswald and his family. He tells each side of the story in a compelling way with narrative, photographs and simple maps. Although the subject matter is heavy, the presentation makes this a great resource. I would highly recommend this book to anyone (young or old) interested in United States Presidential history.

Smarter Every Day

Smarter Every Day is a series of YouTube videos that are posted by a christian man in Alabama. Smarter Every Day shows amazing things about science such as how a jellyfish stings, what happens when an AK-47 is shot underwater, how Harry Houdini died, and what a helium balloon does when in a van that is driving forward. Very much for visual learners.

Cavnaugh Flight Museum

Cavanagh is an air museum in Addison (Dallas) Texas. Cavanaugh has a great collection of aircraft including WWI biplanes all the way up to planes and helicopters from Vietnam. Also, the museum has not only American planes but two MiG fighters as well. The museum has tour guides that tell very interesting stories and they offer flights in historic aircraft including a North American P-51 Mustang and Douglas A-1 Skyraiders. this is a great opportunity to learn about historic aircraft. I recommend it for auditory and visual learners.

The World Wars

 The Usborne book The World Wars is an introduction and extended overview to the history of Europe, the U.S.A, and Russia from 1914 to 1945 especially around World War 1 and World War 11, this is a recourse targeted toward visual learners but audio and kinesthetic learners will not find this book very useful because it is not a very good read-aloud book, nor does it have any exercises to do. I like this book because it provides information on different occurrences in a period that I like to study.

Small gas engines serve us in many ways. They power lawn mowers, tillers, cultivators, trimmers, edgers, snow blowers, chain saws, pumps, generators, air compressors, and other useful home tools. They also power our fun: outboard boats, snowmobiles, motorcycles, all-terrain vehicles, ultralight aircraft, and other toys. To keep them operating efficiently, an owner of these tools and toys should know about small engines: how they work and what to do when they don't.

Small gas engines are made up of individual systems that work together to produce power. Each system has many components. Internal combustion gasoline-powered engines require six systems: fuel, exhaust, ignition, combustion, cooling, and lubrication. In this article, we will discuss the systems and components that make small engines work.

Fuel and Exhaust

The fuel and exhaust systems are critical to operation. They furnish the fuel for combustion and remove exhaust gases. The following are components of a fuel and exhaust system.

Gasoline: Gasoline is a combustible liquid that burns relatively slowly. However, when sprayed as a mist and mixed with air, it is quite explosive. All it needs is a spark. Two-stroke engines require that oil be mixed with the gasoline to lubricate internal parts. Four-stroke engines use a fuel-air mixture.

Fuel Tank: The fuel tank stores fuel in preparation for mixing by the carburetor and use by the engine. Some fuel tanks are pressurized with air to help deliver fuel to the carburetor. Other tanks are non-pressurized and depend on a fuel pump to deliver fuel to the carburetor.

Fuel Line: Fuel is moved from the tank to the pump and/or carburetor through a fuel line. Pressurized fuel systems often have a squeeze bulb in the fuel line for building pressure.

Filter: A carburetor jet has a small opening that can easily become clogged. A fuel filter traps dirt and sediment from the gas before it is delivered to the carburetor.

Pump: A fuel pump produces a vacuum that pulls the fuel from an unpressurized tank, then delivers it to the carburetor.

Carburetor: The carburetor has one job: to mix the correct proportion of gasoline and air for the engine. Too much gasoline in the mixture makes it rich; too little gas makes it lean.

Throttle: The throttle controls the amount of fuel-air mixture that enters the engine from the carburetor. The throttle thus controls the speed of the engine.

Primer: A primer injects a small amount of gasoline into the carburetor throat to make the initial fuel-air mixture rich. A primer is used to help start a cold engine.

Choke: Some engines control the richness of the fuel-air mixture at startup by controlling the air rather than the fuel. A choke reduces the amount of air in the fuel-air mixture.

Governor: A governor is a device that automatically opens the engine's throttle when more power is needed and closes it when the load is light.

Muffler: Small gas engines, especially two-stroke engines, are noisy when they operate. A muffler reduces the sound of the exhaust gases by passing them through baffles.

Spark Arrestor: A spark can exit the exhaust port of a small gas engine, potentially starting a fire on nearby combustibles. A spark arrestor on the exhaust port can reduce the chances of such a fire. Spark arrestors are especially important on chain saws, motorcycles, and all-terrain vehicles operated in dry woodlands.

Ignition

The ignition is a primary system within all small gas engines. It produces and delivers the high-voltage spark that ignites the fuel-air mixture to cause combustion. No spark means no combustion, which means your engine doesn't run. Below are the components found in small engine ignition systems. Some systems will include breaker point ignitions while others depend on solid-state ignitions.

Magneto-Powered Ignition System: A magneto uses magnetism to supply electricity in ignitions where there is no battery. The magneto is turned by the crankshaft, which rotates when the manual recoil starter is pulled. The three types of magneto ignition systems are mechanical-breaker, capacitor-discharge, and transistor-controlled.

Battery-Powered Ignition System: If your small engine includes a battery for starting, the ignition coil will also use it to supply spark to the spark plugs. A battery stores electrical energy until needed. Battery ignition systems also use mechanical-breaker, capacitor-discharge, and transistor-controlled ignitions.

Mechanical-Breaker Ignitions: High-voltage electricity must be sent to the spark plug at the appropriate time. In mechanical-breaker ignitions, this job is performed through the contact points and a condenser.

Points: As the crankshaft rotates, a cam opens and closes a set of contact points. These points function as an on/off switch: Closed is on, and open is off.

Condenser: Because the spark moving across points can damage their surfaces, the condenser stores voltage to reduce arcing between points.

Capacitor-Discharge Ignitions (CDI): A capacitor is a large condenser. A CDI stores and delivers voltage to the coil using magnets, diodes, and a capacitor

Transistor-Controlled Ignitions (TCI): Transistors are electronic controllers. A TCI uses transistors, resistors, and diodes to control the timing of the spark.

Coil: An ignition coil is simply two coils of wire wrapped around an iron core. The coil changes low voltage (6 or 12 volts) into the high voltage (15,000 to 30,000 volts) needed by the spark plug.

Spark Plug: A spark plug is an insulated electrode that is screwed into the top of the engine cylinder. High-voltage timed electricity from the magneto travels by wire to the spark plug. The base of the plug has an air gap of about 0.030 inch (30 thousandths of an inch), which the current must jump.

Wires: The primary wire from the coil to the breaker point and secondary wire from the coil to the spark plug(s) deliver electricity to the ignition components.

Distributor: A distributor is an ignition system for engines with more than one cylinder and spark plug. It distributes the spark to the appropriate cylinder using a rotor, cap, and individual spark plug wires.

Combustion

The combustion system of a small gas engine is where the work gets done. Components of the combustion system include the cylinder block, cylinder head, camshaft, valves, piston, connecting rod, crankshaft, timing gears, and flywheel. To better understand small gas engines, let's look at how this vital system works.

Cylinder Block: The largest single part in a small gas engine is the cylinder block. It is a piece of metal in which the cylinder hole is bored or placed.

Cylinder Head: The cylinder head is the top, or ceiling, of the cylinder and is attached to the block with bolts. Depending on the type of engine, the head may or may not include valves.

Piston: A piston is the movable floor in the combustion chamber. Its upward movement compresses the fuel-air mixture. After combustion, its downward movement rotates the crankshaft.

Crankshaft: An engine's crankshaft is a metal shaft with an offset section onto which the connecting rod is attached. Rotation of the crankshaft moves the piston up in the cylinder. Movement of the piston down in the cylinder then rotates the crankshaft.

Connecting Rod: Between the piston and the crankshaft is a connecting rod. At the larger end of the connecting rod is a bearing that allows rotation around the moving crankshaft. The small end is attached to the piston pin.

Valves: Valves simply open and close passages. A reed valve in a two-stroke engine is activated by changes in air pressure.

Flywheel: At the end of the crankshaft is a circular weighted wheel called a flywheel. The flywheel delivers the engine's power to devices (wheels, blades, etc.) and helps keep the crankshaft turning smoothly.

Cooling and Lubrication

Combustion and friction produce heat. Heat and friction -- if not controlled -- can quickly damage an engine's components. Small gas engines are typically cooled by air. Friction is reduced using movable bearings and lubricants.

Air-Cooling Fins: For simplicity, most smaller gas engines are cooled by air. Metal fins around the outside of the combustion chamber help dissipate the internal heat.

Friction: Friction is resistance that occurs when one surface rubs against another. Friction causes wear. In an engine with many moving parts, friction is reduced with bearings and lubricants.

Bearings: A bearing is a replaceable part that takes the brunt of the friction. A friction bearing relies on lubricants to minimize friction. A nonfriction bearing uses hard steel rollers or balls to prevent wear, though it too requires some lubrication.

Lubricants: Lubricants such as oil and grease reduce surface friction by coating parts with a film. Lubricants in two-stroke engines are applied to surfaces by mixing oil with fuel.

Viscosity: An oil's viscosity is its resistance to flow. The thicker a lubricating oil or grease is, the higher its viscosity number.

Filters: Friction happens. Moving parts wear, even with the best lubricants. The resulting metal as well as carbon from the combustion process must be cleaned from the oil to ensure long lubrication. Some small engines use oil filters to remove contaminants from the circulating oil.

Regularly servicing your small engine will ultimately save you money and time. In the next section, we'll review how, where, and when to service this engine

I like programming and I use Alice

Alice is a free program that you can get to learn about programming, it is a drag and drop program where you have objects move speak and think. you can add objects and then alter them to perfection.
I use Alice to make movies and games like flying space ships and planes. I think it's fun and easy to use.

I like math and I use Life of Fred

Life of Fred is a series of text boot series that takes you though elementary school to collage. I have done the elementary series and have started the before high school series. The books are a story of a 5-6 year-old boy named Fred and his life as a math teacher at KITTENS collage the first part of every chapter is a story about Fred and his life as a teacher and at the end of each chapter it has a "Your turn to play" in witch you do your part and answer questions about stuff you learn  in the chapter about math and sometimes other things. I am currently in the elementary physics book and am laughing and working through the book.

I like math and I use a website called Khan Academy

Khan academy is a mastery learning website where you can learn anything from counting to calculus. I use Khan Academy for my school math and sometimes just for fun. Mostly I use Khan Academy for forth through seventh grades, I find that Khan Academy helps me learn the math that I like at my own pace.

there are two types of tasks. Practice: this is where you start to learn a skill, usually you have to get five to three problems in that skill correct in a row to get it practiced, if you don't know how to do that skill you can usually watch a video that will teach you how to do the skill. Mastery challenge: here you can master the skills you have already practiced by answering a problem in that skill.

There are five levels from practiced to mastered that are: Not practiced, Practiced, Level 1, Level 2, and Mastered.

Kahn Academy

Kahn Academy is a website that uses mastery learning to help people of all learning types learn math, history, Java script, science, and test prep. Kahn academy can be used without an account but is much better with. I like Kahn academy because it is easy to learn on there, the website will ask you a series of questions that if you answer correctly you upgrade that skill to the next level and eventually mastery. Later on it will test you on that skill and possibly downgrade it so that you have to re-master it. In other courses you watch a series of videos and then take a quiz to see if you learned anything. I like to do the math and am trying to master 7th grade as well as doing history after 1700, the SAT test prep is good as well. I recommend Kahn Academy to visual and audio learners because of the videos and to kinesthetic learners for the exercises.
