FOKUS KAJIAN DAN ISU KEPRIHATINAN
Kajian yang dilakukan ini adalah berfokuskan kepada kebolehan pelajar untuk memahami konsep rangkaian dan menggunakan rangkaian LAN (Local Area Network) sebagai kaedah bagi memahami konsep rangkaian. Saya juga menggunakan kaedah amali bagi melengkapi fokus kajian saya. Di dalam refleksi pengajaran dan pembelajaran sebelum ini mendapati terdapat beberapa kelemahan yang perlu diatasi terutamanya dari segi kaedah pengajaran, gaya penyampaian dan pendekatan yang diambil. Sebagai contoh ketika proses pengajaran dan pembelajaran sebelum ini, murid tidak mendapat gambaran yang jelas tentang topik yang diajar kerana guru lebih banyak membaca slaid berbanding membuat penerangan secara terperinci dan memberi contoh.
Bagi topik yang diajar pada sesi lepas, ia sebenarnya memerlukan lebih daripada contoh kerana topik ini melibatkan konsep yang sangat abstract bagi pelajar yang rata-rata masih baru didalam dunia teknolgi.

Support and movement[1]
1. All living things need a support system consisting of a skeleton and muscles to provide structure, movement, and survival.
2. There are three basic types of support systems - exoskeletons which are outside the body like insects, endoskeletons inside the body like humans, and hydrostatic skeletons using fluid pressure like worms.
3. The human skeletal system includes 206 bones that make up the skull, spine, ribs, and limbs to support weight, maintain shape, protect organs, and allow movement.
Animal Support System
This document discusses different types of skeletons and locomotion in animals. It describes three main types of skeletons: hydrostatic, exoskeleton, and endoskeleton. Hydrostatic skeletons use fluid pressure, while exoskeletons are external shells and endoskeletons are internal structures like bones. It also outlines different modes of locomotion including swimming, movement on land through structures like joints and muscles, and flying through wing adaptations. The document concludes with assigning worksheets on topics like the human skeleton, fill in the blank questions, and crossword puzzles.
Nutrition (Chapter 2 Form 5)
The document discusses nutrition and provides information on various topics related to nutrition including:
- The definition of nutrition and the importance of nutrients from food for living organisms.
- Different classes of foods and their calorific values.
- Factors that influence an individual's calorie requirements such as age, gender, body size, and activity level.
- Health problems related to malnutrition and obesity.
- The importance of good nutrition and eating habits for preventing diseases.
Nutrition presentation
The document discusses nutrition and healthy eating, covering the five main food groups, importance of daily exercise, recommended daily servings of fruits and vegetables, benefits of dairy products, and how proper nutrition provides energy, reduces stress and prevents health issues. Key recommendations include eating a variety of fruits and vegetables each day, drinking milk or eating yogurt, getting 60 minutes of moderate exercise daily, and choosing whole grains over refined grains.
Chapter 9 stability
This document discusses stability and center of gravity. It defines an object in equilibrium as stationary or at rest, with all objects having a point of equilibrium. The center of gravity is the point where the earth's gravitational force acts on an object, concentrating its weight, and is the same point as the object's equilibrium. An object's stability depends on the position of its center of gravity - generally, a lower center of gravity makes an object more stable, as seen in examples of vehicles, boats, and animals. The principle of stability through center of gravity should be applied in design.
Chapter 8 support and movement
The skeletal system provides support, protection, movement, and shape to the human body and other animals. There are three main types of skeletal systems - endoskeleton, exoskeleton, and hydrostatic skeleton. An endoskeleton is found in vertebrates and consists of bones or cartilage inside the body. An exoskeleton is an external shell like in insects and crustaceans. A hydrostatic skeleton uses fluid pressure, found in some invertebrates. The skeletal system allows vertebrates and invertebrates to survive on land and in water.
Chapter 7 dynamics
The document discusses different types of forces including frictional force, gravitational force, electrostatic force, magnetic force, and electric force. It explains that a force is a push or pull that can change an object's shape, position, speed, or direction of motion. Forces can be measured using a spring balance and the unit of force is the Newton. The document also discusses work and power, defining work as energy transferred by a force causing movement over a distance.
Chapter 6 air pressure
Air pressure is caused by air particles constantly moving and colliding with surfaces. It presses down on everything from above and its strength decreases with increasing altitude as there is less air. Many tools like syringes and sprayers use air pressure principles in their functions. Safety measures must be followed when working with pressurized gases.
Chapter 5 water and solution
Here are the key ways to control water pollution mentioned on page 41:
- Treat domestic and industrial waste before discharging into water sources. This involves processes like sedimentation, filtration and disinfection.
- Control surface runoff from agricultural land by terracing, contour ploughing and establishing buffer zones along water bodies. This prevents soil erosion and entry of agricultural chemicals into water.
- Proper disposal of solid waste and control of open defecation to prevent entry of pathogens into water sources.
- Control discharge of oil and chemical spills from ships and tankers.
- Maintain minimum flow in rivers to ensure sufficient self-purifying capacity. Abstraction of water should be regulated.

Chapter 4 interdependence among living organisms and the envirronment
This document discusses interdependence among living organisms and the environment. It covers topics such as species, populations, communities, habitats, ecosystems, interactions between living organisms including predator-prey relationships, symbiosis, competition, food webs, and the importance of photosynthesis. Photosynthesis produces oxygen and food for animals while using carbon dioxide, and the carbon and oxygen cycles help regulate gas levels on Earth. Conservation efforts aim to preserve natural resources for future generations.
Chapter 3 biodiversity
Biodiversity refers to the variety of life on Earth, including plants, animals and other organisms. There are two main groups of organisms - animals and plants. Animals are further divided into vertebrates and invertebrates, while plants are divided into flowering plants and non-flowering plants. Biodiversity is found in different ecosystems around the world and is important to study and protect.
Chapter 10 simple machine
This document discusses simple machines. It defines a machine as a device that helps overcome a load with less effort. The six simple machines are identified as the lever, pulley, wedge, screw, inclined plane, and wheel and axle. The lever is then discussed in more detail. It works by turning about a fixed point called a fulcrum, allowing a small effort force to overcome a larger load force. The positions of the load, effort, and fulcrum determine the mechanical advantage of the lever. Simple machines like levers, rollers, and wedges were used to build ancient structures. Modern machines are more complex but still rely on simple machines.
