This document discusses chemical reactions presented in a chemistry class. It includes questions and answers about experiments demonstrating different chemical reactions between substances like iron and copper sulfate, magnesium and oxygen, hydrogen peroxide and manganese dioxide, vinegar and baking soda, and copper sulfate and sodium hydroxide. The reactions produce substances like iron sulfate, copper, magnesium oxide, water, oxygen gas, sodium acetate, carbon dioxide, copper hydroxide, and sodium sulfate. The document also defines reactants and products, and shows how to write chemical equations using symbolic representations of the substances in the reactions.
Modyul 7:Ang Paggawa Bilang Paglilingkod at pagtataguyod ng dignidad ng tao.pptxJun-Jun Borromeo
"Napaglilingkuran ko ang ating bayan." ito ang sagot ng isang sundalo sa isang pastor sa tanong nito kung bakit pinili niyang maging sundalo sa kabila ng panganib ng ganitong trabaho.
Ilan kaya ang kabataan tulad mo ang ganitong motibasyon sa pagpili ng trabaho sa hinaharap? Sa anumang gawaing naitakda mong gawin, isinasaalang alang mo ba ang kabutihang maidudulot nito sa iba - sa pamilya, paaralan, o pamayanan?
Inaasahang masasagot ng modyul na ito ang mga sumusunod na katanungan na: Bakit nga ba mahalaga ang paggawa sa tao? Ano ang mabuting maidudulot nito sa ating pagkatao?
Sa modyul na ito, Inaasahang maipapamalas ang sumusunod na kaalaman, kakayahan, at pag-unawa:
1. Nakikilala ang kakayahan ng paggawa bilang tagataguyod ng dignidad ng tao.
2. Nakakasusuri kung ang paggawa nasaksihan sa pamilya, paaralan o barangay /pamayanan ay nagtataguyod ng dignidad ng tao.
3. Naipapaliwanag ang batayang konsepto ng aralin.
4. Nakakabuo ng sintesis tungkol sa kabutihang naidudulot ng paggawa gamit ang panayam aa mga manggagawang kumakatawan sa taong nangangailangan na nasa ibat ibang karera o trabahong teknikal-bokasyonal.

Hi Guys! So this used to be a group project me and my classmates made during our 4th quarter last school year (the design was mostly my idea though). It solely revolves around the activities of Quarter 4: Aralin 1 in the Grade 10 AP module. I hope you enjoy and make use of it! It somewhat posh in a way so when studying it; sit tight, relax and have a cup of tea!

This tackles the basics and the easiest concept of Chemical reactions. This features only the four basic types of chemical reactions: synthesis, decomposition, metathesis, and ion - exchange reaction.
This is a basic concept because there is a pattern to be followed in each type of reaction.
More types of chemical reactions will be given on my next set of presentation entitled, "Everything You Want to Know About Chemical Reactions."

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
