Microorganisms, also known as microbes, are tiny organisms that can only be seen with a microscope. They include bacteria, fungi, algae, protozoa, and viruses. Microorganisms are found everywhere and can be beneficial or harmful. Beneficial microorganisms are used in food production and agriculture, while harmful microorganisms can cause diseases. Microorganisms undergo life processes like growth, movement, and respiration. They need food, water, and suitable temperatures to survive. Understanding microorganisms and how to prevent the spread of disease is important.

Natural materials come from plants, animals, and rocks, and include wood, cotton, leather, and metal. Man-made materials are produced through chemical processes applied to natural materials, such as plastic, synthetic cloth, and petroleum products. Man-made materials are generally more durable than earlier natural materials due to advances in chemical processing techniques.
The document lists various common household items including paper clips, towels, iron scissors, aluminum cans, screws, a wooden chair, plastic bottles, and needles.

1) The document contains a monthly test on the theme of investigating living things. It has multiple choice questions about basic needs of humans and other living things, as well as their shelter, food, breathing structures and life cycles.
2) The test contains diagrams and figures to illustrate various concepts being assessed such as the basic needs of humans and experiments investigating the needs of plants and animals.
3) Students are asked questions about the inferences that can be made from the experiments as well as correctly matching animals to their breathing structures, shelter and stages in their life cycles.
The Solar System consists of the Sun and nine planets that orbit around it. The Sun is the largest object at the center of the Solar System. There are nine planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto (no longer considered a planet). Each planet has unique characteristics and orbits the Sun in oval-shaped paths of different sizes depending on their distance from the Sun.
The document contains 6 multiple choice questions about animal defenses. Question 1 asks which animal hides in its hard shell when attacked, with options of skunk, crocodile, or tortoise. Question 2 asks which animal can raise its spines when seeing an enemy, with options of spider, porcupine, or cockroach. Question 3 asks what structure moths have to protect themselves, with options of hard scales, false eyes, or sharp spines.
The document discusses six characteristics that help animals protect themselves from danger: sting, sharp spines, sharp claws, hard scales, hard shells, and false eyes. It provides examples of animals that possess each characteristic, such as scorpions and bees that have stings to release poison, porcupines and fish that have sharp spines, and moths that have false eyes on their wings. These characteristics help scare off or injure predators and enemies.
Plants reproduce through various methods like seeds, spores, leaves, stem cuttings, underground stems, and suckers to ensure their survival. Examples of plant reproduction through seeds include papaya and durian. Mushrooms and ferns reproduce through tiny spores that are easily spread by wind. Begonias and bryophyllum reproduce through leaves, while hibiscus, roses, and tapioca reproduce via stem cuttings. Sweet potatoes reproduce underground through stems. Bananas and pineapples reproduce using suckers. If plants did not reproduce, they would become extinct.
The document describes five characteristics that help animals survive in extreme hot and cold weather:
1) Animals in hot desert climates, like camels, have humps to store water and food.
2) Desert foxes have long ears to help lose heat in hot weather.
3) Polar bears have thick fur to keep warm in cold polar regions.
4) Animals in cold climates like penguins, walruses, seals and whales have thick layers of fat to insulate against cold.
5) Arctic foxes have small ears to prevent heat loss in frigid Arctic conditions.
Human reproduce by giving birth to offspring, continuing the process from one generation to the next, which increases the number of people. If humans do not reproduce, the population will decrease, while overreproducing can lead to issues like food and water shortages, lack of living space, high crime, and unemployment due to overpopulation.
This document appears to be an exercise or assignment for students in Year 4 to record their findings from an experiment on the combined uses of materials in a table with three columns for the object, materials used, and properties. The document provides an example table for the students to fill in their own findings.
This document discusses the combined uses of materials in various objects and summarizes their key properties. It examines objects like spectacles, plugs, belts, umbrellas, frying pans, windows, electric irons, shoes and kettles. For each object, it identifies the materials used, such as glass, metal, plastic, leather and rubber, and summarizes their important properties like being transparent, insulating or conducting electricity, flexible, waterproof or able to conduct heat.
