This document provides an overview of key concepts in chemistry including:
1) Matter can exist in three physical states (solid, liquid, gas) and has mass and takes up space.
2) Solutions are mixtures where one substance dissolves evenly throughout another. Solubility describes how much of a substance can dissolve.
3) Atoms are the basic building blocks of matter and consist of a nucleus with protons and neutrons surrounded by electrons in orbit. The number of protons defines the element.
Matter can be described by physical and chemical properties. Matter is capable of undergoing physical and chemical changes based on these properties.

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.

An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. Matter: anything that has mass (weighs something) & takes up space (has
volume). Matter has 3 forms or physical states
Properties of Matter - physical state

3. Some substances are able to dissolve other materials.
If you put sugar into water, the water will dissolve the
sugar. The sugar will soon disappear (sugar molecules
are dissolved in the water)…
Solubility and Solutions
5
• Solution - a special type of mixture where one of the components mixes evenly
throughout (dissolves) so that you can’t visibly see one of the parts.
• Solubility - the property describing how much of a material can be dissolved.
Pepper is not soluble in water. We can say pepper is
insoluble in water.
Salt has a high solubility in water. We can dissolve a lot
of salt in water.
• Dissolving a substance is an example of a phyiscal change. The substance is
STILL THERE, and hasn’t been changed into anything new!
4. Pure substance!
Sprite?
Mixture!
ingredients & a gas (CO2)
Mixture of salts, fish, seaweed…
Only water -
pure
Pure substance!
Sodium Chloride - pure
Mixture!
Let’s play Solution or Not Solution!!
Bottled water?
The ocean? Salt?
5. Metals: properties include malleability,
ductility, good conductors of
heat/electricity, magnetic
Nonmetals: properties include poor
conductors of heat & electricity,
solids are brittle & dull
Metalloids: have both
characteristics of metals
and metalloids
Periodic Table of the Elements
11
The Periodic Table organizes elements into a set of patterns, arranged by
increasing atomic number, invented by Russian chemist Dimitri Medeleev (1869)
6. You are probably familiar with certain elements…
Elements: Hydrogen & Oxygen

7. • Theory of atomic structure says that all atoms consist of:
-
-
-
-
-
-
+
+ +
+
++
Nucleus - contains protons with a positive
charge (+)
and neutrons (neutral, no charge)
Electrons - particles with negative charge
(-) orbiting nucleus in a “cloud”
• An element is identified by the number of
protons in its nucleus, called the atomic
number. An atom having 6 protons in
its nucleus is a called a
carbon atom
• Atoms: smallest building block of which matter is composed, when combined
in specific ratios, they make the elements
