Presentation 2
The document discusses electricity and electrical circuits. It defines key concepts like electric current, circuits, and circuit components including power sources, loads, and connectors. It explains that electric current is the flow of electrical charges through a conductor. A basic circuit requires a power source, a load, and a connecting wire to allow the current to flow in a closed loop from the power source to the load and back. Common circuit components are identified along with their symbols. The effects of adding more batteries, bulbs, or wire length to a circuit are described.

Maleny electricity
Electricity is an electric current that can flow through conductors and is used as a power source. It requires a closed circuit and power supply to flow in one direction through materials. Conductors allow electron flow while insulators do not. Resistors resist but do not stop current. Circuit configurations like series and parallel determine how electricity is distributed; series has one path while parallel has multiple. Parallel circuits are common in buildings to independently power different rooms.
Electricity and Circuits.pptx
Electricity is the flow of electrons through a closed circuit. There are three types of particles in atoms: positively charged protons, neutral neutrons, and negatively charged electrons. Electricity occurs when electrons flow continuously through a loop or circuit, driven by a voltage source like a battery. For electricity to be produced, electrons must be able to move freely through a complete circuit path. Circuits can be either series or parallel: in a series circuit, all components are connected one after another and if one component fails the whole circuit fails, while in a parallel circuit components have independent paths and a failure of one does not affect others.

Electricity & electric circuits
The document provides an overview of electricity and circuits for 5th grade science. It defines atoms as made up of protons, neutrons, and electrons. Electricity occurs when electrons move between atoms. There are two types of electricity - static and current. Current electricity needs a power source like a battery and a complete circuit to flow. Circuit diagrams use symbols for components like cells and wires. There are two main types of circuits - series circuits where a break in one component breaks the whole circuit, and parallel circuits where a break leaves other parts still working. Students are asked to draw and build examples of each.
Electricity and circuits
The document discusses electricity and circuits. It explains that an electric bulb connected to an electric cell with wires will glow, forming a simple electric circuit. A torch uses a battery and bulb connected by a sliding switch - pushing the switch forward completes the circuit and lights the bulb, while pushing it back breaks the circuit and turns the bulb off. The document also defines conductors as materials that allow electric current to pass through, like metals, while insulators do not allow current and include materials like rubber and plastic.
Circuits1
Electricity flows through circuits in a complete path called a closed circuit. Flashlights use batteries to power a light bulb through a closed circuit that is opened and closed by a switch. Circuits require a power source, conductor, and load, with electricity only flowing when the path is complete. Common conductors include metals, while insulators prevent electricity from flowing through materials like plastic or rubber. Circuits can be connected in series with one switch controlling all components, or parallel with individual switches for each component. Standard symbols are used to diagram electrical circuits.
Circuit Notes
This document discusses different types of circuits including closed and open circuits, circuit diagrams, common circuit symbols, series and parallel circuits, and short circuits. It explains that closed circuits allow electricity to flow while open circuits do not. Series circuits have a single path for current to flow and if any part fails the entire circuit fails, while parallel circuits have multiple independent paths so if one fails the others still work. Short circuits bypass devices and drain batteries faster while risking fires from overheating wires.
Electricity(physics)
Electricity can be summarized as follows:
1. Electricity is a type of energy caused by the flow of electrons from negative to positive points. Charge is measured in coulombs and current is the rate of flow of electric charge measured in amperes.
2. Kirchhoff's laws describe the fundamental rules of circuit analysis regarding voltage and current. Ohm's law defines the relationship between voltage, current, and resistance in circuits.
3. There are different types of circuits including series, parallel and combinations. Components behave differently depending on the circuit type regarding voltage and current.
Parallel circuits
A parallel circuit has more than one path for electricity to travel through multiple wires connecting more than one component like bulbs, whereas a series circuit only provides a single path for electricity through a single wire connecting a battery to a single bulb. A parallel circuit example includes three bulbs connected by three separate wires, while a series circuit connects a bulb and battery with just one wire.
Electricity and circuits
This document provides an overview of electricity and electrical circuits. It defines electricity as the flow of electric current and notes that electricity is caused by an imbalance of positive and negative charges. It then explains that an electrical circuit provides a complete path for electricity to flow through devices. Common examples of circuits include household wiring and car batteries. The document discusses the differences between open and closed circuits and how switches are used to open and close circuits to control the flow of electricity.
Electrical energy
Electrical energy is created by the movement of electrons through a circuit. A circuit can be open or closed, with a closed circuit allowing electrons to flow freely and an open circuit preventing flow. Materials that allow or prevent electron flow are conductors and insulators respectively, with common examples like copper and plastic provided.
Electricity
Static electricity builds up charge on objects but does not flow, storing potential energy. Current is the flow of electrons through a conductor, measured in amperes. There are two types of current: direct current flows one way while alternating current reverses direction. Circuits can be series, where all components are on one path, or parallel with multiple branching paths. Conductors easily transmit current while insulators do not. Resistance opposes current flow and is influenced by various material properties. Voltage measures the energy pushing current through a circuit. Ohm's Law defines the relationship between resistance, voltage and current. Electromagnets use current-carrying coils to generate magnetic fields, generators convert mechanical to electrical energy, and motors do the opposite
Basic electricity
This is about electricity. I describe insulators, conductors, parallel circuits, series circuits, and some examples.
changing circuit grade 6
Electricity can only flow in a complete circuit. Changing different components of a simple circuit affects how much electric current can flow. Specifically:
- Adding more batteries increases electrical energy and makes a bulb brighter.
- Adding more bulbs or lengthening wires makes bulbs dimmer due to increased resistance limiting current flow.
- Thicker wires decrease resistance and allow more current to flow, making bulbs brighter.

Electricity
This document discusses electricity and its properties. It explains that electricity is caused by electrons moving between atoms. There are positive protons and neutral neutrons in the nucleus, while negatively charged electrons orbit around it. Electricity can be static, occurring when an imbalance of charges builds up, or current, flowing from one place to another. Current is measured by the amount of charge transferred over time as electrons flow through a conductor. The document also provides instructions for creating simple circuits using batteries, wires, and light bulbs to demonstrate how electricity flows through a closed loop path.
Introduction electrical-circuits
This document discusses different types of electrical circuits. It explains that a circuit provides a pathway for electric current to flow through devices like batteries or generators. Circuits can be either series or parallel. A series circuit has one single pathway for current to flow through components linked in a chain. A parallel circuit has two or more pathways where the current can split up and recombine, resulting in the same voltage across each resistor. The document then describes examples of simple, series, and parallel circuits used in an experiment, noting differences in current, brightness of bulbs, and battery life between the circuit types. It also observes that as more resistors are added in parallel branches, the overall circuit resistance decreases.

2) How an electroscope can be used to demonstrate induced charge and the attraction and repulsion of charged objects.
3) The basic concepts of electric charge, magnetic fields, and how circuits work using concepts like voltage, current, and resistance.
4) How transformers can change the voltage and current in a circuit to effectively step voltage up or down using a change in the ratio of coils in the primary and secondary windings.
Electricity for Kids
Electricity is a form of energy that results from charged particles like electrons and protons either accumulating in one place or flowing as a current. It is generated by moving electrons off of atoms, leaving them with more protons than electrons. Copper, silver, and gold are good conductors of electricity, while wood, cotton, and insulators conduct it poorly. Common household appliances like lamps, fans, vacuums, and air conditioners require electricity to function.
1. reaction of electrons
This document discusses the fundamentals of electricity, including:
- Atoms are made up of protons, electrons, and neutrons, with protons being positively charged and electrons being negatively charged.
- In conductors like copper and aluminum, electrons are loosely bound and can easily move between atoms when a source of electromotive force is applied, creating an electric current.
- An electric current is the regulated flow of electrons, with one coulomb equaling approximately 6.24 quintillion electrons flowing for one second, which is defined as one amp.
How does electricity affects our life
Electricity affects our lives in many ways. It is the flow of electric charges called current. Electricity allows devices like lights and appliances to function. Current flows through circuits which must be closed loops with a power source, wires, and a load. Circuits can be connected in series or parallel. Safety devices like fuses and circuit breakers help control electric current and prevent hazards by opening the circuit if current flow becomes too high. Proper use and understanding of electricity helps ensure it benefits our lives safely.
E4 Introducing Electricity Part 2
This document provides information about series and parallel circuits:
- A series circuit connects components one after another to form a single path for current, while a parallel circuit splits into multiple branches with more than one path for current.
- In a series circuit, if one component fails the entire circuit is broken, while in a parallel circuit other branches still work if one fails.
- Common household light circuits are wired in parallel so individual lights still work if one burns out.
2 ppt-suspension.
A suspension is a mixture where particles are mixed with but undissolved in a liquid and over time the particles settle to the bottom. Distillation is a process used to separate liquids with different boiling points by evaporating the mixture and then condensing the vapors to separate the liquids.
Immune and endocrine system
The immune system is a network that protects the body through cells, tissues, and organs working together. The endocrine system is composed of glands that release hormones into the bloodstream to regulate bodily functions.

Presentation1 What is electricity
The document discusses the basics of static electricity and atoms. It explains that atoms are made up of positively and negatively charged particles that attract or repel depending on their charge. Static electricity occurs when objects come into contact and transfer electrons, resulting in an imbalance of charges. Examples given include rubbing a balloon or cloth to build up an excess of negative charges, which can then stick to walls or paper due to attraction between opposite charges. Lightning is also described as a large-scale discharge of built up static charges between storm clouds and the ground.
Heart beats
The document discusses how to measure your heart rate and factors that affect it. It explains that a person's heart rate, or pulse, is the number of heartbeats per minute, with the average being around 80. A doctor uses a stethoscope to listen to sounds in the chest to check the heart rate. The heart is made of muscle and located in the center of the chest. The circulatory system involves the heart pumping oxygenated blood to the body through arteries and deoxygenated blood back to the lungs through veins to be re-oxygenated.
Food pyramid
The document discusses the importance of a balanced diet and getting food from the main food groups including carbohydrates, vegetables and fruits, dairy and meat, and fats. It emphasizes eating more of carbohydrates like grains and less of fats. A balanced diet provides vitamins, minerals, protein for growth, and energy. It also stresses the importance of daily exercise and warns about the health risks of smoking cigarettes.
Nervous system
The nervous system is made up of the brain, spinal cord and nerves, which work together to control body organs, coordinate muscle movement, and interpret information from the senses. The brain and spinal cord form the central nervous system, which connects to nerves throughout the body to monitor and control organ functions and muscle activity based on sensory feedback.
Magnets
Iron particles are lined up when a magnet is brought close to iron. When two bar magnets are placed close together with the same poles facing, they will repel each other. The magnetic field consists of field lines that emerge from the North pole and reenter at the South pole. Magnets are made of iron, nickel, or cobalt. Magnetic materials such as iron and steel are attracted to magnets, while non-magnetic materials like plastic and wood are not. To preserve a bar magnet, it should be stored with another magnet to maintain its magnetic field.
4 ppt states properties
This document discusses different states of matter and their properties. It defines solids, liquids, and gases based on their particle arrangement, attraction forces, and ability to change shape or volume. Key properties discussed include melting point, boiling point, freezing point, and density. Matter is defined as anything that has mass and takes up space. Mass is the amount of substance in an object, while volume refers to the space an object occupies. Density relates the distribution of mass within a given volume.
Respiratory system
The document describes the basic anatomy and function of the respiratory system. It lists the main organs - nose, trachea, lungs, and diaphragm. The respiratory system brings oxygen into the body through breathing and removes carbon dioxide, allowing oxygen to be delivered to the blood and carbon dioxide to be removed, while the diaphragm and lungs work together to enable breathing.
3 ppt methods of separation
Filtration, magnets, evaporation, and distillation can be used to separate mixtures. Distillation involves separating liquids with different boiling points by evaporating and condensing them. The process of distillation separates liquids using evaporation and condensation.
3 pp twater cycle
The water cycle begins when water from bodies of water evaporates into water vapor due to heat from the sun. The water vapor condenses into water droplets in the air that form clouds. The water droplets in clouds join together and become too heavy, causing rain or snow to fall back to the ground. When rain falls on land, some water soaks into the soil and is used by plants, some becomes groundwater, excess water runs off into streams and rivers, and some evaporates back into the air to repeat the cycle.
Electric Safety rules
This document provides safety tips for handling electricity, advising to not play with electric sockets or plugs, not to touch electricity with wet hands, and to avoid poking fingers or other objects into electric sockets, toasters, or other appliances.
4 ppt reversible and irreversible change
The document discusses reversible and irreversible changes. Reversible changes can go forward or backward and do not result in new substances, such as folding paper or melting butter. Irreversible changes result in one or more new substances and cannot be undone, like burning wood or iron rusting. Examples are provided of both reversible changes like freezing orange juice and irreversible changes like burning a matchstick.
5 ppt irreversible change
This document discusses the differences between physical and chemical changes, noting that chemical changes are irreversible and result in new substances, while physical changes are reversible. It provides examples of evidence of chemical changes, including changes in color, scent, the presence of bubbles or fizzing, and the release or absorption of heat during reactions like rusting, silver tarnishing, toasting marshmallows, antacid tablets reacting with vinegar, and a fire.
electricalconductorsandinsulators 090711231749-phpapp01
Electrical conductors allow electric current to flow through them, such as metals like copper and aluminum. Good electrical conductors are also generally good heat conductors. Electrical insulators do not allow electric current to flow through, such as plastics, wood, rubber and glass. A circuit tester can be used to determine if a material is a conductor or insulator by seeing if it allows a bulb in the circuit to light up when placed between the wires.
1 pp tmatter
Matter is anything that has mass and takes up space. There are three main states of matter: solids, liquids, and gases. Examples of the different states include ice as a solid, water as a liquid, and air as a gas.
Teeth
Teeth are used to break down food into pieces for swallowing. They come in different shapes for different functions - incisors cut, canines tear and hold, and molars grind and chew food. Humans have two sets of teeth - milk teeth that are replaced by 32 permanent adult teeth which will not regrow if lost. Teeth have layers including enamel, dentin, and a pulp chamber.
Digestive system
The digestive system is a long tube running through the body that breaks down food into nutrients. Food enters the mouth where teeth grind it and saliva begins breaking it down before the tongue pushes it into the esophagus for swallowing. The stomach uses strong acids to further break down food while the liver and pancreas produce juices to digest it in the small intestine, where nutrients are absorbed and undigested waste moves to the large intestine to leave the body through the anus.

Seriesandparallel 100430110505-phpapp02
This document discusses series and parallel circuits. A series circuit has only one path for current to flow, so if one appliance fails the entire circuit is broken. A parallel circuit has more than one path for current, so if one appliance fails the others can stay on. Key differences are that in a series circuit all appliances turn off if one fails, while in a parallel circuit the other appliances can remain on if one fails.
Series and parallel
Series circuits have a single path for current to flow, so if one appliance fails the entire circuit is opened and current cannot flow to other appliances. Parallel circuits provide multiple current paths, allowing other appliances to remain lit if one fails since current can still flow through other paths. The key difference is that series circuits rely on a single current path, while parallel circuits provide alternatives.
Electricity
Electrons moving through a closed circuit create electricity. An electromotive force like a battery pushes electrons through wires and loads such as light bulbs. Circuits can be connected in series, where there is only one path for electrons, or parallel, where there are multiple pathways. In series circuits, if one load fails the entire circuit fails, whereas in parallel circuits other loads remain lit if one fails. Common examples of series circuits include lamps and refrigerators, while power grids and home lighting use parallel circuits.
SCIENCE LESSON FOR GRADE 5 QUARTER 3LEARNERS
1. The document discusses series and parallel electric circuits. A series circuit allows current to flow through a single path, so if one bulb burns out the entire circuit is broken. In a parallel circuit there are multiple current paths, so individual bulbs can be removed without affecting the others.
2. It provides examples of series and parallel circuits and compares their advantages and disadvantages. Series circuits require less wiring but the failure of one device disables the whole circuit, while parallel circuits allow individual control but need more complex wiring.
3. The text examines examples of each type of circuit and assesses readers' understanding with questions about circuit parts and their properties in series and parallel configurations.
Parallel and series
This document discusses series and parallel lighting circuits. A series circuit has only one path for current to flow through all components sequentially. If one component fails, the entire circuit is broken. A parallel circuit has multiple current paths so that if one component fails, the others can still receive current. Parallel circuits are more commonly used in households because a single failure won't cause all lights to turn off.

ELECTRICAL-CIRCUITS.pptx
This document provides an overview of basic electrical circuits. It defines key concepts like electric current, voltage, and different circuit components. It explains that current flows from the negative to positive terminal in a circuit. Circuits can be connected in series or parallel. In series circuits, the current is the same at all points and the voltage is shared. In parallel circuits, the current splits and the voltage is the same across each component. Ammeters and voltmeters are used to measure current and voltage in different parts of a circuit according to set rules.
Electrical Circuits
An electric circuit is formed with electrons that flow from a voltage source like a battery through a conductor like wire to a load and back to the source, completing the circuit. Key components include a power source, wires, and a load such as a light bulb. Circuits can be open or closed, with closed circuits allowing continuous current flow and open circuits interrupting flow. Circuit types include parallel, series, and series-parallel configurations.
Circuits
An electric circuit is a closed path that allows electrons to flow from an energy source and back. A closed circuit allows continuous electron flow, while an open circuit interrupts flow. Common circuit components include batteries, wires, switches, bulbs and resistors. Circuit diagrams use symbols to represent components and visualize connections before building real circuits. Series circuits have a single current path, so adding resistors increases total resistance and dims all bulbs. Parallel circuits provide multiple paths, so adding resistors decreases total resistance despite each path's resistance increasing.
Intro to electricity
This document contains notes from a lesson on electricity. Some key points include:
- Electricity is the flow of electrons in a circuit powered by a battery or other energy source. An electric current is measured in amps and is the rate of flow of electric charges.
- Circuits can be arranged in series or parallel. A series circuit has components connected one after the other, while a parallel circuit splits into two or more branches.
- Other concepts covered include electric fields, voltage, resistance, and the relationships between current, voltage, power, and resistance defined by Ohm's law. Hands-on modeling of electric circuits used "pretzels" representing electrons.

Ch.10.acids and alkalis (3rd week)..
1) Acids and alkalis undergo a neutralization reaction where an acid reacts with an alkali to form a salt and water.
2) Common examples of neutralization include reactions between acids like hydrochloric acid, sulfuric acid, and nitric acid with alkalis like sodium hydroxide and potassium hydroxide.
3) Neutralization reactions have many applications including relieving insect stings, curing indigestion, baking cakes, putting out fires, and improving poor soil quality affected by acid rain.
Thermal energy
Thermal energy is the energy of moving particles that makes up heat. Heat is the transfer of thermal energy between objects when they are at different temperatures. Temperature measures the amount of thermal energy in an object, with higher temperatures indicating more thermal energy. Thermometers measure temperature using liquids that expand when heated, allowing the user to read the temperature in degrees. Thermal conductors easily allow the transfer of heat, like metals, while insulators do not, like plastics and wood. Common materials are identified as conductors or insulators based on their ability to transfer thermal energy.
Ch.10.acids and alkalis (2).
Robert Boyle discovered that red cabbage juice and violets could be used as acid-base indicators. Red cabbage juice turns red in acids and green in alkalis, while violets turn purple in acids and greenish-yellow in alkalis. He also found that the juice from lichen (litmus) changed color between acids and alkalis and could be used on paper strips. This led to the development of the pH scale to quantify the strength of acids and alkalis from 0-14 based on their hydrogen ion concentration. Common pH indicators like methyl orange and phenolphthalein change color over different ranges on the pH scale to indicate whether a solution is acidic, basic, or neutral.
Ch.10. acids and alkalis (1).
This document discusses acids and alkalis. It notes that ancient Egyptians and Greeks observed that some substances taste sour while others feel slippery. Scientists later named sour substances "acids" and slippery substances "alkalis." Examples of acids found in nature include citric acid in oranges and lactic acid in muscles. Vinegar contains ethanoic acid. Acids can be classified as organic, produced by living things, or mineral. Common alkalis include sodium hydroxide, calcium hydroxide, and limewater. Concentrated solutions of acids and alkalis are corrosive, while dilute solutions are irritants. Alkalis are found in household cleaners and react with skin fat to produce soap-like substances.
Acids and alkalis 3
This document discusses neutralization reactions between acids and bases. It provides examples of common acids like hydrochloric, sulfuric, and nitric acid reacting with bases like sodium hydroxide and potassium hydroxide to form salts and water. Additional examples are given for using neutralization reactions to cure bee stings, treat indigestion, make baking powder rise in cakes, improve acidic soil for crop growth, and reduce the effects of acid rain by neutralizing it. The document also covers how neutralization can be used to clean teeth and dissolve mineral scales from kettles.
Acids and alkalis 2
Litmus is used to detect acids and alkalis. It can be used as a solution or absorbed into paper strips. Litmus solution turns red in acid and blue in alkali, while litmus paper turns red in acid and blue in alkali. The pH scale measures acidity and alkalinity from 0 to 14, with 0 being the strongest acid and 14 the strongest alkali. pH levels between 0-2 are strong acids, 3-6 are weak acids, 7 is neutral, 8-11 are weak alkalis, and 12-14 are strong alkalis.
Acids and alkalis 1
This document discusses acids and alkalis found in daily life. It notes that while some acids are corrosive, others like citric acid are found in foods and give them their sour taste. Examples of acids in living things include citric acid in oranges and lemons, ascorbic acid in fruits, lactic acid in muscles, and uric acid in urine. Vinegar contains ethanoic acid, also known as acetic acid, which is produced when oxygen reacts with ethanol in wine over time. Acids can be classified as organic acids produced by living things or mineral acids not produced by living things. While concentrated acids and alkalis are corrosive, dilute solutions are safer to handle.
Magnet 1
Magnets are made of iron, nickel, cobalt, or steel. To preserve a bar magnet, you should store it with another magnet pointing in the opposite direction to maintain its magnetic field. When a magnet breaks, its magnetic field also breaks into smaller magnetic fields. An electromagnet generates a magnetic field through a coil of wire when electric current passes through; placing an iron core in the coil makes the magnetic field stronger. Materials like iron, nickel, and cobalt are magnetic, while materials like aluminum, copper, glass, plastic, wood, and silver are non-magnetic.
Thermal energy ppt 1
Thermal energy is the energy of moving particles that causes heat. Heat is the transfer of thermal energy between objects when they are at different temperatures. The document discusses conductors and insulators - materials that easily allow heat to pass through them are conductors like metals and materials that do not are insulators like rubber. It provides examples of common objects and whether they are thermal conductors or insulators.
Heat story
The saucepan was being stirred by a wooden spoon while heating gravy. The hood suggested using a metal spoon instead, but the wooden spoon argued it would not catch fire unless put in the gas flame. The saucepan, with a wooden handle, and kettle, with a plastic handle, agreed their materials keep the heat from reaching what they are holding. The window explained it does not let cold in but instead keeps the heat in the kitchen from escaping, which would result in it feeling cold without this function.
forces Presentation 2
Water exerts two main forces - upthrust force and water resistance. Upthrust force causes objects to float and is felt when holding down a floating object underwater. Water resistance is felt when walking or swimming through water, as water pushes back against movement. Air resistance also impacts moving objects, slowing them down depending on size, and can be useful for parachutes which use air resistance to slow falling.
forces Presentation 1
Forces cause objects to move, change direction, or stop moving. Unbalanced forces cause motion while balanced forces do not. Friction is a type of force that opposes motion between two surfaces and causes moving objects to slow down and stop. The more mass an object has, the greater its weight due to gravity.
Rock uses
This document discusses the uses of four different types of rocks: slate, granite, chalk, and marble. Slate is used for roofing tiles and billiard tables because it is hard, impermeable, and slips easily into thin sheets. Granite is used for steps, roads, buildings, and schools because it is hard and impermeable and doesn't wear away easily. Chalk is used for writing on blackboards because it is formed from sea creatures and wears away easily. Marble is used for floor and wall tiles and statues because it has attractive texture and color and can be cut and polished.
Types of soil
Soils are mixtures of bits of rocks, dead plants and animals, air and water that support plant growth. Different soil types like sand, silt and clay are distinguished by the size of their particles and how much air and water they hold. Sand drains easily while clay drains poorly, meaning different soil types support different plants.
Light energy
1. Light is a small part of the electromagnetic spectrum and can travel through a vacuum without a medium, unlike sound waves.
2. Light travels in transverse waves and when it hits objects can be absorbed, reflected, or pass through.
3. The major natural light source is the sun, while other sources can be natural or man-made. Objects like the moon and water reflect rather than generate light.
Types of soil
Soils are mixtures of bits of rocks, dead plants and animals, air and water that support plant growth. Different soil types contain particles of different sizes that impact drainage and which plants can grow best. Sand soil has large particles and drains easily while clay soil has tiny particles, few air gaps, and does not drain easily.
Minerals and rocks
The document discusses the three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form when magma or lava cools and hardens. Sedimentary rocks form through the compaction and cementation of sediments. Metamorphic rocks form when existing rocks are changed by heat, pressure, and chemical reactions deep underground. The rock cycle shows how the three rock types are interrelated as one rock type transforms into another over time.
Ch.11.less.1.how are forces and motion related?
1) The document discusses different types of motion including up and down, straight line, round and round, zigzag, and back and forth motion. It also discusses distance, direction, forces, and types of forces including balanced and unbalanced forces.
2) Forces can make something move, change an object's direction or speed, or change an object's shape. Examples of forces include gravity, friction, and air resistance.
3) Balanced forces do not change an object's motion, while unbalanced forces can make an object start or stop moving or change directions.
Light gb
Light comes primarily from the sun. It can also come from other natural sources like the moon or man-made sources like lamps. The moon and mirrors do not produce their own light but reflect light from other sources.
Light travels in straight lines and can pass through transparent materials, pass through translucent materials partially, or be blocked by opaque materials. The way light interacts with objects determines whether they appear colored or form shadows. Reflection and refraction explain how light bends when moving between different materials like air and water.
Ch.12.less.2.what are the properties of sound [autosaved] [recovered]
The document discusses key properties of sound including that it is a type of energy that moves through matter as longitudinal waves of vibrations called sound waves. It moves through three parts of the ear - outer, middle, and inner - and can be reflected as echoes. The pitch and frequency of sounds are related, though pitch is how our ears perceive it, and volume refers to the density of compressions and rarefactions in the air. Materials like wall padding and foam can absorb sound waves to reduce echoes and noise.

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.

Title: Gravitational wave detection with orbital motion of Moon and artificial
Abstract:
In this talk I will describe some recent ideas to find gravitational waves from supermassive black holes or of primordial origin by studying their secular effect on the orbital motion of the Moon or satellites that are laser ranged.The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

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.

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.
