The earth in the solar system
This document discusses our solar system and celestial bodies. It explains that our solar system consists of the sun, eight planets, moons, asteroids and comets. Jupiter is the largest planet and Mercury the smallest. The document defines celestial bodies as objects that shine in the night sky, including the sun, moon and stars. Stars are defined as celestial bodies that produce their own heat and light, with the sun being the largest star in our solar system. It describes how ancient people used constellations like the Big Bear and Little Bear to determine directions at night and find the pole star.
Mercury
Mercury is the planet closest to the Sun, located about 36 million miles away. It is named after the Roman messenger god Mercury. Mercury has extreme temperature variations between day and night, with daytime temperatures reaching 800 degrees Fahrenheit and nighttime temperatures plunging to -280 degrees. Mercury also has a very thin atmosphere and no moons or evidence of current geological activity.
Our universe
The document discusses key facts about our planet Earth. It begins by providing context about our solar system and universe. It then explains that Earth is the third planet from the sun and the only planet that supports life. The document goes on to describe how Earth formed from a hot cloud of gases and cooled over millions of years, developing a crust, mantle and core similar to an egg. Volcanoes are mentioned as openings where molten material from the core is forced out of the crust.

The document discusses the universe and our solar system. It describes the universe as a vast expanse containing stars, planets, moons, dust and gases. It notes that the Earth is very small compared to the universe. It then discusses the components of our solar system, including the sun, eight planets, and moon. The sun is at the center of our solar system and the earth is the only known planet that supports life.
The earth and its neighbours
The document discusses the Earth and its place in the solar system. It describes the Earth's rotation and revolution around the Sun, which causes the seasons. It also discusses other planets, stars, galaxies and satellites. The Earth formed from a ball of dust and gases and has a molten core, mantle and solid crust. Volcanic eruptions occur when gases and liquids from the core breach weaknesses in the crust.
Solar System
The Solar System consists of the Sun and objects that orbit it, including 8 planets, dwarf planets, asteroids, and comets. The inner Solar System contains terrestrial planets like Earth that are composed of rock and metals. The outer Solar System contains gas giants like Jupiter and Saturn that account for most of the mass. Objects follow elliptical orbits around the Sun, with closer objects moving faster according to Kepler's laws of planetary motion. The Solar System is believed to have formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud.
Phases of the Moon
The Moon appears to change shape daily as it orbits Earth and the illuminated side facing Earth varies. These changing shapes are called phases of the Moon, ranging from a thin crescent to a full Moon. The phases - new, crescent, half, gibbous, and full - refer to the portion of the Moon's face that is illuminated by the Sun's light and visible from Earth, with the waxing phase showing the illuminated area growing larger each night and the waning phase showing it shrinking smaller again.
Introduction to Earth
Earth is composed of four main layers - crust, mantle, outer core, and inner core. The crust is the outermost layer and is made up of either continental or oceanic crust. Below the crust is the mantle, which is divided into lithosphere, asthenosphere, upper mantle, and lower mantle. The outer core is a liquid layer made of nickel and iron that generates Earth's magnetic field. The inner core is made of solid iron deep within Earth. Overall, Earth's composition is approximately 34.6% iron, 29.5% oxygen, and 15.2% silicon.

6th Std 1. The Earth in the solar system
The universe contains all of space, time, matter and energy, including planets, stars and galaxies. It is approximately 93 billion light years in diameter and has been expanding since its creation. Our solar system is part of the Milky Way galaxy and contains the Sun and eight planets that revolve around the Sun on elliptical orbits, along with asteroids, meteoroids and other celestial bodies. The four inner, terrestrial planets are Mercury, Venus, Earth and Mars, while the four outer, gas giant planets are Jupiter, Saturn, Uranus and Neptune. Earth is unique in its ability to support life.
The Sun and our Solar System
The Sun is a middle-aged, average sized yellow star that is made up mostly of hydrogen and helium. It is about 4.6 billion years old and located 93 million miles from Earth. The Sun generates heat and light through nuclear fusion reactions in its core that convert hydrogen into helium. It is the center of our Solar System and contains over 99% of the mass in the entire system. The Solar System also includes eight official planets that orbit the Sun, along with dwarf planets, moons, asteroids, comets, and other small bodies.
The movements of the Earth
The Earth moves in two ways: by rotating on its axis daily, and by revolving around the Sun yearly. The Earth's tilted axis and oval-shaped orbit cause the seasons by changing the angle and duration of sunlight received in different parts of the world throughout the year. The rotation of the Earth causes day and night, and the revolution around the Sun in 365 days causes the four seasons as the Earth's positioning shifts solstices and equinoxes.

PSA Exam Pattern
The document provides information about the Central Board of Secondary Education's (CBSE) Problem Solving Assessment (PSA) for classes 9 and 11. The PSA will assess skills like quantitative reasoning, qualitative reasoning, language conventions, critical thinking, problem solving and communication. It will count for 10% of the total class 9 assessments and the score will carry forward to class 10 where students can improve their score. The 60 minute multiple choice test will be administered in schools on February 14, 2013 and will consist of 60 questions assessing areas like quantitative reasoning, qualitative reasoning and language conventions.
Food and Nutrition
1. All living things require food for growth and repair, though plants can produce their own food through photosynthesis while animals and some other organisms obtain food from other living things.
2. Food provides organisms with nutrients like carbohydrates, proteins, fats, vitamins, minerals, and water which are broken down and absorbed for energy, growth and cell repair.
3. Digestion and absorption of food occurs through different processes depending on whether an organism is unicellular like an amoeba or multicellular like humans and animals, but all involve the breakdown of food into simpler compounds that can be used by the cells of the body.
Measurement Estimation
The document discusses measurement accuracy. Some measurements like vegetables and distances can be estimated, while others like gold, medicines, and machine parts need to be accurate. The required level of accuracy depends on the purpose of measurement. Advances in technology now allow for more accurate measurement of things like time, distance, mass, and chemical compositions. However, mistakes can still occur due to limitations of instruments or observer negligence. Laws and regulations aim to prevent inaccurate measurements from cheating customers.
Food and preservation of food
The document discusses food preservation and adulteration. It explains that food preservation aims to make food available throughout the year by storing it in ways that maintain quality. Common preservation methods include drying grains, boiling liquids, refrigerating or freezing perishables, and using salts, spices, oils or sugars to preserve items like pickles. Adulteration involves mixing high quality food with lower quality ingredients, which can harm health. Governments regulate food to prevent adulteration.
Reproduction in Living Things
1. Reproduction is a natural process that allows living things to produce offspring of the same type in order to perpetuate their species.
2. Living things can reproduce sexually, with male and female gametes, or asexually without sex organs through various vegetative, spore-forming, budding, or fragmentation methods.
3. Sexual reproduction in plants involves pollen transfer for fertilization to produce seeds containing embryos that grow into new plants, while animals sexually reproduce through internal fertilization leading to offspring that receive nourishment initially through eggs or live birth.
The Organisation of Living Things
The document discusses the organization of living things from the cellular level to the ecosystem level. It explains that living things are organized in a hierarchical manner, from cells to tissues to organs to organ systems to organisms and finally populations within an ecosystem. At each level, the parts work together interdependently to carry out functions necessary for life. The ecosystem level represents the broadest level of organization, where living things interact with each other and their non-living environment.
Effects of Heat
Heat causes materials to change between solid, liquid and gas states. Solids expand and become fluids when heated, liquids boil and become gases, and gases expand. Materials change states at specific temperatures. State changes can also be caused by removing heat. The temperature at which a material changes state is unique to that material. Heat causes all materials to expand and contract with temperature change.
Motion and Types of motion
This document discusses different types of motion. It defines speed as the distance traveled in a specific time. There are several types of motion including linear motion, oscillation motion, rotary motion, irregular motion, and circular motion. Linear motion involves traveling in a straight line at a constant or varying speed. Oscillation motion refers to movement from one end point to another and back again. Rotary motion is when an object passes through the same point while rotating.
Electric Charge
Static electric charge develops when objects are rubbed together, such as a plastic comb rubbed through hair. This causes an imbalance of electric particles between the two objects. Glass develops a positive charge when rubbed with silk, while ebonite becomes negatively charged when rubbed with wool. Like charges repel each other, while unlike charges attract. The electroscope can detect electric charge by the separation of its gold leaves when a charged object touches it.
Transmission of Heat
Heat can be transferred through three methods: conduction, convection, and radiation. Conduction involves the transfer of heat between particles in direct contact through vibrations. Convection occurs through the circulation of hotter and colder parts of a fluid. Radiation transfers heat through electromagnetic waves and does not require a medium. Thermos flasks and containers help retain the temperature of foods and drinks by trapping air between layers of glass or plastic that act as insulators to prevent heat transfer by conduction, convection, or radiation.
Propagation of Sound
This document is comprised of 15 pages that are each copyrighted by the Jnana Prabodhini Educational Resource Centre. No other substantive information is provided.
Propagation of Light
1. Light travels in a straight line and can be reflected. When light hits a non-transparent object, it changes direction rather than passing through. The reflected light then reaches our eyes, allowing us to see objects.
2. Experiments can demonstrate the linear propagation of light using a laser, tubes, cardboard with holes, or observing dust particles in a beam of light. Light will only pass through holes that are aligned.
3. Shadows are formed when a light source is blocked by an object. A point light source will create a dark umbra shadow, while an extended source makes both a dark umbra and a faint penumbra shadow. Solar and lunar eclipses occur through the formation of shadows
Natural Resources
The document discusses natural resources and their classification. It defines natural resources as things through which man's basic needs are met, including air, water, soil, minerals, plants and animals. Renewable resources like plants and animals can reproduce and regrow when destroyed. Non-renewable resources like air, water and soil cannot be reproduced and their supplies are limited. The document emphasizes the importance of conserving both renewable and non-renewable natural resources and provides suggestions for reducing pollution and practicing sustainable use.
Characteristics of Living Things
Living things have several key characteristics: they are made of one or more cells, can move on their own, respond to their environment, grow and develop, reproduce, require food and oxygen, and experience a life cycle from birth to death. Non-living things do not possess these characteristics and are not made of cells.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
