[Q3] Simple Machines

Simple Machines


Simple machines are basic mechanical devices that make it easier to do work. They are called "simple" machines because they have few or no moving parts and are relatively easy to understand and use. There are six types of simple machines: lever, wheel and axle, pulley, inclined plane, wedge, and screw. These machines are often the building blocks of more complex machines and are used in everyday life to make work easier. Simple machines work by either multiplying force, changing the direction of force, or increasing distance over which force is applied.

Lever: A rigid bar that is used to lift or move heavy objects by applying force at one end.

Wheel and Axle: A simple machine made up of a circular object (wheel) that rotates around a rod or axle.

Pulley: A simple machine made up of a wheel with a groove that a rope or cable can run through.

Inclined Plane: A flat surface that is tilted at an angle, used to lift heavy objects by reducing the amount of force needed to move them.

Wedge: A simple machine that is shaped like a triangle and is used to split or separate objects.

Screw: A simple machine made up of an inclined plane wrapped around a cylinder, used to hold objects together or to lift them by turning the screw.

[Q3] ENERGY TRANSFER

  Exploring the Transformation of Energy: Sound, Heat, Light, and Electricity By: Pj Miana   Introduction: Energy is all around us, and it can take many forms. In this lesson, we'll delve into how different types of energy—sound, heat, light, and electricity—can be transformed from one form to another. Understanding these transformations helps us comprehend the world and the technology we use every day.   1. Sound Energy: Sound energy is produced by vibrations traveling through a medium, such as air, water, or solids. It can be transformed in various ways:   - Mechanical to Sound : When an object vibrates, it creates sound waves. For example, when you pluck a guitar string, the mechanical energy of your hand's motion is transformed into sound energy.   - Sound to Electrical : Microphones transform sound waves into electrical signals. These signals can then be amplified and converted back into sound through speakers.   2. Heat Energy: Heat energy is

SEPARATING MIXTURES BY: PJ MIANA Introduction Understanding and mastering techniques for separating mixtures is not only a fascinating aspect of science but also an essential life skill. In our daily lives, we encounter a multitude of mixtures, from the ingredients in our kitchen to environmental challenges such as pollution and water purification. Learning how to effectively separate mixtures is crucial for solving real-world problems, making informed decisions, and gaining a deeper understanding of the world around us. In this lesson, we will explore various techniques such as picking, winnowing, decantation, the use of magnets, sieving, filtering, and evaporation. These techniques are not only fundamental to scientific inquiry but also find practical applications in industries like agriculture, food processing, environmental science, and more. By grasping these methods, we empower ourselves to tackle complex challenges, conserve resources, and contribute to a cleaner and more sustai
