Plastics
This document discusses plastics, including polymers, the different types of plastics, their properties, how they are identified, how they are transformed, and their environmental impact. Polymers are large molecules made of repeating smaller molecules called monomers. There are natural polymers from plants and animals as well as synthetic polymers called plastics that are made from petroleum. Plastics are categorized as thermoplastics, which can be remolded, and thermosets, which can only be molded once. Plastics are lightweight, flexible, resistant to impact and moisture, and good insulators. They can be identified based on how easily they scratch, their density, and how they burn. Plastics are transformed using processes like
Project 2 plastics
1) The first step in obtaining plastics is sourcing raw materials like crude oil, natural gas, and coal. These raw materials are then processed to extract and purify polymers.
2) The second step is synthesizing monomers by chemical reactions. Monomers are small subunits that link together to form polymers.
3) Additional steps include synthesizing basic polymers through polymerization, and incorporating additives to plastic polymers to give them desired properties and make them useful for applications.
Project 2 plastics
The document summarizes the key steps in the plastic production process:
1) Sourcing of raw materials like crude oil and natural gas. Raw materials are altered before manufacturing.
2) Synthesis of monomers which are combined through chemical reactions to form polymers.
3) Polymerization where many monomers link together to form larger polymer molecules.
4) Incorporation of additives to plastic polymers to provide desired properties and functions. Additives include antioxidants, stabilizers, and pigments.

Ch05 classification of matter
The document discusses different ways of classifying matter and the physical properties used to classify materials. It describes density, strength, hardness, flexibility, conductivity, melting and boiling points as physical properties used to group materials. Materials are classified into five main classes: metals, plastics, glass, ceramics and fibres based on their properties. Choosing the right material depends on considering the function and desired properties of an object.
Materials
Materials are used to make many everyday objects and come in natural and man-made forms. Wood comes from trees and is used for furniture, boats, and paper because it is stiff, can be shaped, and looks nice. Metal comes from rocks, is strong, hard, and smooth, and is used for cars, watches, and cutlery. Plastic is usually made from oil and is used for toothbrushes, chairs, and cups because it can be stiff or bendy and is easy to clean. Glass is made by heating sand and is used for bottles, windows, and glasses because it is hard, allows you to see through it, and is strong. Fabric comes from plants and animals and is used for
Class 1 unit 5. material things

Energy
The document discusses two forms of energy: heat and light. It describes an experiment to demonstrate heat energy by having students feel which spoon (metal, plastic, or wooden) warms up fastest when placed in hot water. The metal spoon warms up fastest because metals are good conductors of heat, while materials like wood and plastic are insulators. Light is another form of energy, with the major source of light for Earth being the sun.
Synthetic Fibres.pptx CLASS VII OF SCHOOL
Synthetic fibers and plastics are made from polymers created through polymerization of monomers. Common synthetic fibers include rayon, nylon, polyester, and acrylic. Rayon is a semi-synthetic fiber made from cellulose. Nylon is strong and elastic. Polyester is durable and dries quickly. Acrylic is soft and wool-like. Lycra, or spandex, is highly elastic. Common plastics include thermosetting plastics like bakelite and thermoplastics like polyethylene, PVC, and nylon. Synthetic fibers and plastics have various applications but can pollute the environment if not disposed of properly.
Plastics
The document discusses the process of plastic production from sourcing raw materials to the final product. Raw plastic materials are sourced from coal, oil and natural gas. Plastics are created through polymerization of monomers, which are often extracted from petroleum. Additives are added to plastics to give them desired properties before they are shaped using processes like injection molding, blow molding, and extrusion. The document also examines the different types of plastics like thermoplastics, thermosets, and elastomers as well as their physical, mechanical, chemical and biological properties.

Heart food presentation
The students helped volunteer at a food distribution program that provides meals to poor people once a week. They helped pack and distribute food to those in need. Through this experience, the students learned the importance of appreciating what they have, not wasting food, and contributing to help those less fortunate. Donations of food can be placed in a collection box near the staff room to support this program.
Water
Swimming, snorkelling, and surfing are some of the oldest water sports. Swimming has been practiced since ancient times and was the second largest Olympic sport. Snorkelling allows one to explore the underwater world without heavy equipment. Surfing originated hundreds of years ago in Hawaii and Australia and has evolved from heavy wooden planks to lightweight fiberglass boards. Safety is important for all water sports, such as not swimming alone, only snorkelling in calm conditions, and studying surf conditions before going out. Proper equipment like swimsuits, fins, masks, and boards are also needed for safe participation.
Japanese occupation
The Japanese defeated Singapore in 1942 through strategic military tactics. They destroyed British warships and planes, landed undetected in Thailand, and outmaneuvered British forces in Malaya. The Japanese bombed Penang and seized control of the busy port. Despite brave resistance from Allied forces, the Japanese marched into Kuala Lumpur, securing food and ammunition. They then defeated Allied forces from both land and sea in Johor, allowing some troops to retreat to Singapore while others helped bomb a key bridge. Ultimately, the Japanese used tanks to shift Singapore's defenses, allowing them to attack and force Singapore's surrender by controlling its food supply routes.
