Flat Knitting Machine
Flat knitting is a method for producing knitted fabrics in which the work is turned periodically, i.e., the fabric is worked with alternating sides facing the knitter. A "Flat" or Vee Bed knitting machine consists of 2 flat needle beds arranged in an upside-down "V" formation.
Study on Flat Bed Knitting Machine
This document is an 11-page lab report on studying a flat bed knitting machine. It includes diagrams of the machine's yarn path, needle beds arranged in a V formation, and cam carriage system. The report describes the machine parts like the needle beds, yarn carriers, and different cams. It explains the knitting action where the needle butts are lifted and lowered by the cam system to transfer stitches and form new loops. The conclusion states that this experiment provided an introduction to flat bed knitting machine operations and settings that could help with industrial applications.
Circulatory system
The circulatory system transports nutrients and oxygen around the body using blood, blood vessels, and the heart. Blood picks up oxygen from the lungs and nutrients from digested food, then is pumped by the heart through blood vessels to deliver these to tissues before returning carbon dioxide and waste to be removed. The heart is a muscle located in the chest that continuously pumps blood to circulate nutrients and oxygen to all parts of the body.
Respiratory system
Our respiratory system takes in oxygen through our nostrils and windpipe, which divides into bronchi leading to our lungs. In the lungs, oxygen passes into the blood while carbon dioxide passes out of the blood and into the air we exhale, allowing our bodies to intake oxygen and remove carbon dioxide. The key parts of the respiratory system that enable this process are the nostrils, windpipe, bronchi, and lungs.
Unit 7 machines
Machines are instruments that make work easier. There are two types of machines: simple machines and complex machines. Simple machines have one or two parts and include pliers, screwdrivers, bottle openers, and pencil sharpeners. Complex machines have many parts and include washing machines, electric screwdrivers, watches, and bicycles. All machines need energy to work, with some using fuels like those in cars, planes, and buses, others using electricity like hairdryers and electric drills, and some using human energy like staplers and scissors.
Machines functions
Machines help with various tasks at home, work, and leisure. Home appliances like vacuum cleaners, washing machines, and dishwashers assist with chores, while communication devices such as tablets, phones, and computers allow people to connect. Transportation machines from cars and motorbikes to planes and shuttles help with mobility, and entertainment machines provide enjoyment during free time.
People and machines
Machines make work easier for people in different jobs. Mechanics use tools like pliers, screwdrivers, and spanners to fix machines. Farmers rely on tractors, rakes, and combine harvesters to plant and harvest crops. Doctors also use machines like syringes, ultrasound machines, X-rays to examine and treat patients.
Energy
There are six main types of energy: kinetic, electrical, chemical, light, sound, and thermal. The document also discusses renewable and non-renewable sources of energy. Non-renewable sources like coal, petroleum, and natural gas are limited and pollute the environment when burned, while renewable sources like the sun, wind, water, and organic matter are unlimited and do not pollute.

Light
Light is a type of energy that travels in invisible waves and always in straight lines. It has no volume or mass but we can see it. When an object blocks light, it forms a shadow. Light is actually made up of seven colors in the light spectrum, and every object absorbs some colors and reflects others, which is why a leaf appears green, a red car appears red, black objects absorb all colors and get hot, while white objects reflect all colors and stay cool.
Matter changes presentation
This document describes several chemical reactions involving oxygen. It shows water (H2O) as the product of a wood fire with oxygen and heat. It also lists milk undergoing lactic fermentation to produce cheese and flour, water and yeast producing bread when heated. Finally, it indicates iron reacting with oxygen forms rust and an apple reacting with oxygen becomes oxidized.
Invertebrates
The document discusses different types of invertebrates including mollusks like snails and clams, jellyfish, sponges, starfish, earthworms, arthropods like insects and spiders, and crustaceans like crabs and lobsters. It notes that 97% of all animals on earth are invertebrates and they are found everywhere and come in many different types.
Apis crew
This document contains profiles for 5 passengers boarding an Apis crew spaceship. Each profile lists the passenger's name, age, country, jobs, likes, and dislikes. The passengers come from countries like the USA, Japan, South Africa, Mexico, and Spain and have jobs as commanders, scientists, doctors, pilots, and an automatic helper. Their interests include various sports, hobbies, films, foods and activities.
Emergencies and first aid
Dr. Lorraine Djali is the doctor on the Apis spaceship mission. She notes that there are many first aid kits on board to handle emergencies like fractures, burns, choking, cardiac or respiratory arrest, and wounds. The first aid kits contain items like disposable gloves, antiseptic wipes, bandages, sterile dressings, adhesive tape, tweezers, and scissors to clean, disinfect, and dress wounds. Dr. Djali provides instructions on using these various items to treat different medical issues until further help can be reached.
Score against cholesterol
This document recommends consuming fats from vegetables like walnuts, berries, peanuts, and oats which raise good HDL cholesterol levels, while advising against fats from animals like red meat, butter, and fried snacks which raise bad LDL cholesterol levels. It also suggests practicing sports and meditation to increase HDL cholesterol levels.
Reproductive system
Maggie is 7 months pregnant and will explain the basic human reproductive system, which involves the ovaries producing eggs, the testicles producing sperm, and fertilization occurring when a sperm fertilizes an egg to reproduce.
Parts of the circulatory system
The circulatory system consists of blood, which transports oxygen, nutrients, carbon dioxide, and waste throughout the body in blood vessels. Blood is composed of plasma, red blood cells, white blood cells, and platelets. The heart, located in the chest, pumps blood continuously through arteries to organs and returns blood through veins, ensuring organs receive oxygen and nutrients and remove waste.
Respiratory system
The respiratory system includes the nostrils, windpipe, bronchi, lungs and diaphragm. It allows oxygen to enter the bloodstream when breathing in through the nose and nostrils, then passes through the windpipe and bronchi into the lungs, where oxygen passes into the blood in the alveoli and carbon dioxide passes out of the blood and into the air to be breathed out. The diaphragm contracts and relaxes to help draw air in and push air out during breathing.

Dónde hay más población
La mayor parte de la población mundial vive en Asia, seguida de África, Europa, América Latina y el Caribe, América del Norte y Oceanía. Las áreas más densamente pobladas tienden a ser las regiones con climas templados y acceso a recursos como agua dulce y tierras fértiles.
The excretory system
The excretory system helps the body eliminate excess water and waste products through the kidneys, ureters, bladder, and urethra. The kidneys filter blood and remove waste and water, which travels through ureters to the bladder for storage until it is full and signals the brain to empty through the urethra.

Volume and mass
Mass is the amount of matter that an object contains, while volume is the space that matter occupies. Mass is measured in grams and kilograms by using scales to weigh an object. Volume can be measured using liters to determine how much space an object takes up.
Water
Water is an example of matter that exists in three states: as a gas over 100°C, as a liquid between 1-99°C, and as a solid below 0°C. It is made of hydrogen and oxygen, has volume and mass, and is odorless, colorless, and tasteless. Water changes state through heating and cooling, melting when heated as a solid, evaporating when heated as a liquid, freezing when cooled as a liquid, and condensing when cooled as a gas.
The states of matter
Solids maintain their own shape and occupy a fixed space, while liquids take the shape of their container but maintain a fixed volume, and gases expand to fill their container.
Science: Studying a clover
Clovers are plants that are born, grow, and die. They have roots, stems, flowers, and leaves, and use their flowers to reproduce. Flowers have male stamens that produce pollen and female pistils with ovules inside, and pollen fertilizes the ovules to create seeds and fruit.
Types of nutrients
All foods contain nutrients that provide energy and support growth and repair of the body. The five main types of nutrients are carbohydrates, fats, proteins, vitamins, and minerals. Carbohydrates and fats provide energy for activities, while proteins help us grow and repair tissue. Vitamins and minerals work to maintain overall health and well-being. People should eat a variety of foods to get necessary nutrients but limit unhealthy fats which can lead to overweightness.
