Ancient civilizations like the Egyptians, Greeks, and Indians were applying chemistry in various ways as early as 1000 BC without realizing it, such as purifying metals, dyeing cloth, fermentation, and making medicines. Some of the earliest intentional chemical reactions involved processes like fire. The Egyptians were purifying gold as early as 2600 BC. Chemistry later developed into branches including organic chemistry, inorganic chemistry, physical chemistry, and biochemistry. Chemistry now has many applications and roles in industries, forensics, health, teaching, entrepreneurship, and more.
Hey I'm DIVYA SHREE NANDINI and I'm here going to present my topic on OXYGEN. Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O
2. Diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. As compounds including oxides, the element makes up almost half of the Earth's crust.

The great advances made in Chemistry began with the discovery of fire. With the fire, the man was able to cook their food and got a heat source to heat and protect from wildlife. The kitchen was then the first chemical laboratory, as it were preserved food through cooking. Later, Alchemy emerged that spread in different civilizations, as among the Chinese, Hindus, Egyptians, Arabs and Europeans and among his ideals unattainable the philosopher's stone and the elixir of long life. Robert Boyle is considered by some the father of Chemistry, being responsible for transforming Alchemy in Chemistry, as he introduced the "scientific method". The Lavoisier's ideas gave the chemical the first solid understanding of the nature of chemical reactions. Several advances have created many distinct branches in chemistry, including biochemistry, nuclear chemistry, chemical engineering and organic chemistry. Chemistry achieved scientific status only in the mid-eighteenth century that was previously treated as a branch of Medicine. With the advent of the Industrial Revolution came a demand for professionals in the chemical area, making possible the creation of the first courses and Chemical Societies in Europe and the United States.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.
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.
5. HISTORY OF CHEMISTRY
By 1000BC ancient civilizations where applying different branches
of chemistry. Examples are purifying and extracting metals, dying
cloth materials, fermentation of wine, cosmetics, painting,
medicines, embalming, food making, and making alloys.
first chemical reaction that was used in a controlled manner was
“FIRE”.
Greeks, Indian, and Egyptians where the ones to first to
utilize chemistry without realizing it.
Purification of metals was first recognized as early as 2600 BC by
the Egyptians when they purify gold
