Flowers contain male and female parts that work together to reproduce seeds. Pollen from the male part must be transferred to the female part through pollination by wind or animals. This allows reproduction to occur, resulting in seeds protected inside fruits. Seeds are dispersed from the fruits and germinate into new plants when they receive water, nutrients, and the right temperature conditions. The plant life cycle then continues as seeds grow into new plants.
This document describes the different types of teeth and their functions. It discusses the four types of teeth: incisors, which cut food; canines, which tear and hold food; premolars, which have a grinding function; and molars, which grind and chew food. It also notes that humans have two sets of teeth - milk (primary) teeth when young, which are later replaced by permanent adult teeth starting around age 6 or 7 years old.
Teeth have the function of breaking down food into pieces small enough to swallow. There are different types of teeth suited to specific functions, such as incisors for biting, canines for tearing, and premolars and molars for grinding food. Teeth break down food through biting, tearing, and grinding motions.
The food pyramid outlines the major food groups including carbohydrates, vitamins and minerals, protein, and oils. It recommends filling your plate with fruits, vegetables, dairy, and meat to create a balanced meal and get the necessary nutrients. A balanced meal incorporates foods from all the major food groups.
There are three main types of teeth: incisors, canines, and molars. Incisors are flat teeth located at the front of the mouth that cut food. Canines are sharp, pointed teeth on the sides of the mouth after the incisors that hold and tear food. Molars are flat, wide teeth located at the back of the mouth that grind and chew food. Humans have two sets of teeth, milk (baby) teeth and permanent teeth. Milk teeth number 20 total while permanent teeth number 32 total. Bacteria in the mouth feed on sugar from leftover food and produce acid that causes tooth decay if plaque is not removed by brushing.
Science tools and safety rules ppp wikiMaha Hussain
This document outlines lab safety rules and describes common science tools. The safety rules instruct students to wear goggles and gloves to protect their eyes and hands, and not to put anything in their mouth or touch anything hot without permission. The science tools section then defines and explains the uses of various pieces of lab equipment, including safety goggles, hand lenses, microscopes, thermometers, droppers, conical flasks, beakers, funnels, test tubes, graduated cylinders, digital balances, and stop watches.
Plants have several key parts that allow them to grow and survive. Roots anchor the plant and absorb water and nutrients from the soil. Some plants store food in their roots. Roots can be taproots or fibrous. Stems support the plant, carry water and nutrients throughout, and come in different forms like flexible green stems or stiff woody trunks. Leaves contain chlorophyll and are the main site of photosynthesis, where plants use sunlight, carbon dioxide, and water to produce oxygen and food (sugar). While plants vary in shape and size, they all share characteristics like having the same basic parts, producing their own food, and being unable to move.
The document discusses four state changes of matter: melting changes solids to liquids, evaporation changes liquids to gases, freezing changes liquids to solids, and condensation changes gases back to liquids when they contact a cold surface.

The toaster, cooker, and kettle debate where heat comes from to toast bread and boil water. The toaster claims it is the only thing that can toast bread, but the cooker says its grill can also toast bread. They ask the kettle what heats it up, and the plugs in the sockets say the electricity flowing from them is what provides heat. The socket agrees, stating electricity from it is changed into heat inside each appliance. The kettle concludes the socket is right that electricity from the substation is ultimately responsible for the heat. The document ends warning children not to play with electricity as it can be dangerous.
Light is a form of energy that allows us to see, while darkness is the absence of light. Various light sources like the sun, stars, flashlights and light bulbs emit light. Objects reflect light, which then enters our eyes and allows us to see. Shadows form where light is blocked and take on the same shape as the blocking object, with shadows longest before noon and shortest at noon. A prism can separate white light into the seven colors of the visible spectrum. Dark colors absorb more sunlight than light colors, so dark clothing is best for staying warm in winter.
Matter is anything that has mass and takes up space. There are three main states of matter: solids, liquids, and gases. The state that matter exists in depends on how closely or loosely packed the particles are and the strength of attraction between the particles. Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have indefinite shapes and volumes. Matter can change between states, such as ice melting into water when heat is applied, changing the phase from solid to liquid.
Electricity is very important in our daily lives and it would be difficult to function without it as many things in our homes rely on electricity. The document discusses where electricity comes from including main electricity from outlets and batteries. It defines important electricity terms like power plants, sockets, plugs, and wires. Current electricity can be converted into different types of energy like heat, light, sound, and movement. The document concludes with safety rules around water, overloading sockets, and switches.
This document discusses the characteristics of living things. It explains that all living things (1) grow, (2) reproduce by making more of their kind such as through birth, laying eggs, or making seeds, and (3) respond to their environment by growing towards light, fleeing danger, etc. It also discusses the needs of living things like water, space, food, and gases and how plants and animals obtain these needs differently. The key stages of the human life cycle are outlined as well as examples of non-living things.
This document discusses the differences between physical and chemical changes and provides examples of evidence of irreversible chemical changes. Specifically, it notes that physical changes are reversible while chemical changes are irreversible. It then lists four main types of evidence that can indicate an irreversible chemical change has occurred: 1) a change in color, 2) a change in scent, 3) the presence of bubbles or fizzing, and 4) heat being released or absorbed during the change. Examples like iron rusting and silver tarnishing are given as illustrations of changes in color, while toasting marshmallows represents a change in scent.
This document discusses phase changes between solid, liquid, and gas states of matter. It notes that heating and cooling can cause materials to change between solid, liquid, and gas phases through the processes of melting, freezing, evaporating, condensing, and others. The key factors that cause these changes are temperature and whether it is hot or cold.
The document discusses reversible and irreversible changes. Reversible changes can go forward and backward, such as folding paper or melting butter. Irreversible changes cannot go backward, like burning wood or rusting iron. Examples are provided of changes that are reversible, like freezing orange juice or dissolving salt in water, and those that are irreversible, including burning a matchstick or toasting bread.
This document discusses what animals need to survive, including water, oxygen, shelter, and food. It explains that animals and plants are alike in that they are living things that need water, gases, and space. However, animals can move and respond to their environments using senses, while plants cannot move or find their own food. The document then covers specific needs in more detail, such as how different animals obtain and use water, oxygen, shelter, and food depending on their body structures and behaviors. It also categorizes animals as herbivores, carnivores, or omnivores based on their diets and teeth shapes.
This document discusses series and parallel circuits and the properties of conductors and insulators. It explains that in a series circuit, if one bulb is removed the other bulb will not light, while in a parallel circuit the other bulbs will still light if one is removed. It provides examples of materials that are conductors, like silver, copper and aluminum, and insulators, like plastic, rubber and glass. It then has questions to determine if examples provided are conductors or insulators.
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.
The document discusses series and parallel circuits. It provides examples of series circuits with one path and defines that if one light bulb is removed, the circuit is open and other bulbs will not light. Parallel circuits are defined as having more than one path, and if one light bulb is removed, the current passes through another path and the other bulb will still light. The document draws examples of both series and parallel circuits.
Soils are mixtures of rock particles, organic matter, air, and water that support plant growth. The type of soil depends on the size of its particles, with sandy soil having large particles and many air gaps allowing for good drainage, clay soil having tiny particles and few air gaps so it drains poorly, and silt soil being intermediate. Different plant types grow best in different soil types depending on their drainage and composition.
This document describes different types of weather and seasonal changes. It discusses the 4 seasons and how the temperature is hot in summer when light clothes are worn, and cold in winter when dark heavy clothes are worn. Spring is warm when flowers bloom, and autumn is cool as tree leaves fall. It also defines different types of precipitation like rain, snow, sleet and hail, and describes the wind as air movement that can be either strong or light.
Minerals are found in rocks and there are over 3000 known types of minerals. Minerals have different properties like color, hardness, streak, and luster that can be used to identify them. There are three main types of rocks: igneous rocks which form from cooling magma or lava, sedimentary rocks which form from compressed and cemented sediment, and metamorphic rocks which form from other rocks being subjected to heat and pressure below the earth's surface. Common rocks like granite, shale, and marble are used for construction materials, building monuments, and other purposes due to their unique properties.
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 charges. Static electricity occurs when objects come into contact and transfer electrons, resulting in an imbalance of charges. Examples given include rubbing a balloon or ruler to build up an excess of electrons, causing it to stick to other surfaces. Lightning is also described as a large-scale discharge of built up static charges between storm clouds and the ground.
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 cancel each other out and do not change an object's motion, while unbalanced forces can cause an object to start moving, speed up, slow down, or change direction.
This document discusses the basics of electricity and electrical circuits. It explains that electricity is the flow of electric charges through a wire, just as water flows through a river. An electrical circuit needs three main components - a power source like a battery, a load such as a light bulb, and wires or other connectors to complete the circuit. It also discusses concepts like open versus closed circuits, and how changing components like batteries or bulbs affects brightness. Symbols are introduced for common circuit elements. Worksheets are included to have the reader draw sample circuits.
There are three main types of motion: straight motion which involves moving in a straight line, circular motion where an object moves in a circle, and back and forth motion where an object moves from side to side or up and down.
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, wood, and paper. Common examples of conductors and insulators are provided.
The document discusses different forces exerted by water and air. There are two main forces of water: upthrust force, which causes objects to float, and water resistance, which pushes against moving objects in water. Air also exerts forces, including air resistance, which slows down moving objects by pushing against them, with larger objects experiencing greater resistance. Air resistance can be useful, as seen with parachutes which use the force of air to slow a falling object.

2) Friction is a type of force that opposes motion when two surfaces are touching, causing moving objects to slow down and stop. The amount of friction depends on the surfaces and how rough or smooth they are.
3) Mass and gravity determine an object's weight, with heavier objects having greater weight. Weight can be measured using a force meter or spring scale.
The document discusses magnetic and non-magnetic materials. Magnetic materials include metals like iron, nickel, cobalt and steel that are attracted to magnets. Non-magnetic materials include aluminum, silver, gold, paper, glass, plastic, rubber and wood that are not attracted to magnets. It provides examples of different objects and whether they are magnetic or non-magnetic when tested with a magnet.
To safely handle magnets, wear protective eyewear and gloves to avoid injury from breaking or flying pieces. Handle magnets gently by slowly bringing them together and avoiding dropping or banging them, which can reduce their strength. Store magnets away from devices, tapes, cards, and screens where magnetic fields can cause damage or distortion. Also, keep magnets dry and do not heat them.
Magnets have been known since ancient times when a shepherd named Magnus discovered that an unusual black rock had the power to pull iron objects like his staff and sandal nails towards it. This became known as the first recorded discovery of a magnet. Different types of magnets exist, with some able to attract or repel other magnets depending on which poles (north or south) are placed close together. Magnets have been studied for centuries but still hold mysterious properties about the forces they exert.
Magnets are made of iron, nickel, cobalt, or steel. To preserve a bar magnet long term, you should store it with another magnet to maintain its magnetic field. When a magnet breaks, its magnetic field also breaks into smaller fields in each broken piece. An electromagnet generates a magnetic field through a coil of wire when electric current passes through; placing an iron core inside the coil strengthens the magnetic field. Materials can be magnetic, like iron, cobalt, and nickel, or non-magnetic, like aluminum, copper, glass, plastic, and wood.
The document discusses the properties of iron and magnets at the particle level. It asks questions about what iron particles look like, how iron is attracted to magnets, what magnets are made of, and how to preserve a bar magnet long-term. It prompts the reader to draw diagrams of magnetic fields with arrows and labels to illustrate the alignment of iron particles when brought near a magnet.
This document discusses ecosystems and how living and non-living things interact within them. It defines key terms like producers, consumers, decomposers, food chains, and food webs. Producers (plants) produce their own food, consumers (animals) eat other organisms, and decomposers (fungi, bacteria) break down dead organisms, recycling nutrients. Food chains show energy transfer between organisms, while complex food webs connect multiple chains in an ecosystem. All organisms depend on each other for survival.
A habitat is the place where a living thing lives and finds food, water, air and shelter. It includes not just a home but the surrounding area as well. Some examples of habitats include ponds for ducks and frogs, oceans for whales, grass for butterflies, trees for birds, deserts for camels, soil for earthworms, tundra for polar bears, and fields for cows.
The document describes 4 different habitats: 1) Woodland habitat which is an open space with few trees and lots of grass home to animals that live in the ground or grass. 2) Tree habitat which is home to animals that live in or on trees. 3) Pond habitat which is a body of still fresh water home to plants and animals that live in or near the water. 4) Under the log habitat which lacks light and is home to minibeasts that feed on rotting wood or prey on other minibeasts.
This document groups bodies of water into flowing water like streams and rivers, and still water like lakes and ponds. It also discusses different aquatic ecosystems like estuaries where freshwater and ocean ecosystems meet, and marshes and swamps that are wet during some or all of the year. Algae lives near the ocean's surface to photosynthesize using sunlight.
The tundra biome has very little rainfall and long, icy cold winters with short, cool summers. Plants in the tundra grow close to the ground and have shallow roots to access melting snow. Animals like caribou and musk ox have thick fur and layers of fat to stay warm, and many hibernate through the winter, while birds migrate south.
The taiga is the largest biome and is known as a coniferous forest, which is a cold forest. It has long, cold winters and short, warm summers with moderate rainfall. Common plants include spruce and fir, while animals that live in the taiga include black bears and moose, which have adaptations like thick fur to survive the cold climate.
The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

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.
