The document describes an experiment to make mixtures of solids and liquids. Students are instructed to half-fill test tubes with water and add pinches of various solids (salt, oil, sugar, copper sulfate). They observe whether each solid "disappears" or dissolves in the water. The conclusion discusses the definitions of solutions, solutes, and solvents. When a solid dissolves in a liquid, it is the solute and the liquid is the solvent, forming a solution. An undissolved mixture is a suspension.

FREEDOM OF THE HUMAN PERSON.pptx
The document discusses the origin of human freedom from a Catholic theological perspective. It argues that freedom comes from the doctrine of Imago Dei, which states that humans are created in the image and likeness of God. The Catechism of the Catholic Church teaches that through Christ, the divine image within humans, though disfigured by sin, has been restored. Most importantly, humans are endowed with freedom, reason, and free will as manifestations of the divine image, which are gifts from God. Therefore, the essence and origin of human freedom is ultimately from God.
Blueplate Meal Service
The Blue Plate Meal Service involves dividing a plate into sections and serving preset portions of food in each section. It originated in the early 1900s using actual blue plates. Advantages are convenience and being economical for small spaces or tables, while disadvantages include limited choice and fixed portion sizes. The food is cooked and plated in the kitchen then served to diners seated at their tables. It was popular for family meals and children's parties due to its ease and is considered a precursor to modern fast food service.

Nominalization intro
Nominalization is the process of using nouns instead of verbs to describe events in formal written English. This makes the language less personal and more impersonal. Spoken English typically uses verbs to describe actions and events, while written English often expresses events as nouns or noun phrases. Nominalization allows writers to discuss topics in a less direct, more objective way that sounds more authoritative.

SOLUTIONS (2).pdf
1. The document provides information about solutions and mixtures from a science textbook. It includes definitions of pure substances, mixtures, and different types of solutions.
2. Experiments are described to classify mixtures as homogeneous or heterogeneous, and as solutions, colloids, or suspensions based on particle size.
3. Key factors that influence solubility, such as temperature, pressure, and surface area, are also discussed through examples of saturated, unsaturated and supersaturated solutions.
7 Science Chapter 8.ppt
This document provides an overview of solutions and factors that affect the dissolving process. It defines a solution as a homogeneous mixture that appears as a single substance. Solutions are made up of a solute, the substance that dissolves, and a solvent, the substance the solute dissolves in. The rate at which a solute dissolves, or its solubility, depends on properties like temperature, pressure, the size of solute particles, and stirring. Higher temperatures typically increase solubility for solids but decrease it for gases. Smaller solute particles and higher pressures also increase solubility.

The document contains learning outcomes, activities to engage students in identifying homogeneous and heterogeneous mixtures, and an interactive exploration of solute-solvent interactions and colligative properties like freezing point depression and boiling point elevation.
solutions
The document discusses key concepts about solutions including:
1) A solution is a homogeneous mixture composed of a solute dissolved in a solvent. Solute particles separate and mix with solvent particles through solvation.
2) Solubility is the maximum amount of solute that can dissolve in a solvent at a given temperature. Concentration, temperature, and pressure can affect solubility and rate of dissolution.
3) Colligative properties depend on the number of particles in solution and include boiling point elevation, freezing point depression, and osmosis. Higher concentrations result in higher boiling points and lower freezing points.
Activity
The document provides instructions for an experiment on acids and bases. Students are asked to:
1) Perform experiments dropping blue-pea juice into lemon juice, orange juice, soap, and detergent and observe any color changes.
2) Record the results and whether each solution demonstrated acidic or basic properties.
3) Present their lab results to the class.

Unit 37 wk4
Here are the key points about hazardous substances:
- Hazardous substances used in salons/labs include things like acids, alkalis, oxidizing agents and volatile liquids.
- These substances must be used carefully according to safety instructions to avoid harm.
- They should be stored securely in clearly labeled containers, away from heat sources and separated based on hazard type. Proper PPE must also be worn when handling them.
Ch.10.elements, compounds and mixtures (part 2)
The document discusses solutions, solvents, solutes, and mixtures. It defines key terms like solution, solute, solvent, dissolve, soluble, and insoluble. A solution is formed when a solute dissolves in a solvent. The solvent is the liquid and the solute is the substance that dissolves. If a substance dissolves, it is soluble, while something that does not dissolve is insoluble. Particle diagrams are used to illustrate solutions and insoluble mixtures. Chromatography is introduced as a technique to separate mixtures based on the solubility of substances.
Purification Of Substances 1
The document discusses various methods of purifying substances, including filtration, crystallization, and evaporation. It provides details on the principles and procedures of these purification techniques. Filtration is used to separate insoluble solids from liquids or solutions. Crystallization produces pure solids from solutions and is used if the solid decomposes upon strong heating. Evaporation removes the solvent from a solution, leaving behind the pure solid, and is used if the solid does not decompose with heat.
Mixtures
The document discusses different types of mixtures including solutions, suspensions, and colloids. It explains that a solution is a homogeneous mixture of two or more substances where a solute dissolves evenly throughout a solvent. Suspensions are heterogeneous mixtures where insoluble particles settle out of the mixture. Colloids have intermediate particle sizes that do not settle out.
Q1 week 2- SOLUTIONS
Solubility is affected by temperature, particle size, and stirring. Usually, increasing the temperature increases solubility as it provides more energy for particles to separate. Finer particles dissolve faster than larger ones because they have a greater surface area exposed to the solvent. Stirring improves solubility by reducing concentration gradients that inhibit dissolving. Other factors like amount of solvent, nature of solute and solvent, and immiscibility also influence solubility rates. Experiments showed that salt, sugar, and detergent dissolved faster with increased temperature, finer particles, and stirring.
MIXTURES(APPEARANCE AND USES)
This document describes experiments on solubility conducted over 4 days:
- Students observed how various solids like sugar, salt, and detergent dissolved in water. Temperature, particle size, and stirring affected solubility. Finer particles and higher temperatures increased dissolution rates.
- Solutions were defined as homogeneous mixtures where a solute fully dissolves in a solvent, like sugar in water. Factors like amount of solvent and manner of stirring impacted solubility.
- Through experiments, it was shown that increased temperature, finer particle size, and stirring facilitated faster dissolution of solutes like sugar and salt in water. The nature of the solute and amount of solvent also determined dissolution rates.
Dissolving and_crystalizing
This document discusses the process of dissolving and crystallizing solutions. It defines solids and liquids, explaining that solids have a rigid structure and fixed shape while liquids can flow freely. Solutions are formed when a solvent dissolves a solute, such as salt dissolving in water to form salt water. The text then provides examples of heating salt water and liquid copper sulfate, noting that the water evaporates in salt water leaving crystalized salt behind. Students are instructed to prepare salt water and copper sulfate solutions to observe changes over time and compare to their hypotheses.
Unit a mix & flow of matter
1. Fluids are substances that have no fixed shape and can flow, including liquids and gases. Fluids are found in many technologies and natural processes.
2. Fluids help with transporting materials like oil sands in slurries, processing materials like melting sand into glass, and holding other materials like ingredients in toothpaste.
3. Fluid properties like viscosity, density, and compressibility determine how fluids behave and can be used. Understanding these properties allows for developing new fluid technologies.
Mixtures 1-2 Separating a Solution
This document discusses separating a salt solution through evaporation. It explains that when water evaporates from a salt solution, it leaves behind salt crystals. The document instructs students to set up evaporating dishes with saltwater solutions and observe what remains after evaporation. It is observed that the water evaporates, leaving behind salt crystals that can be identified by their cubic shape and sometimes X-like patterns.
Vocab solutions
The document provides definitions and explanations of key concepts in solutions and solubility including:
- Saturated solutions are holding as much solute as possible, while unsaturated solutions are not holding as much as possible. Dilute solutions have little solute compared to solvent, while concentrated solutions have lots of solute.
- Adding salt raises the boiling point of water. Super saturated solutions hold more solute than normally possible. Water is not the only possible solvent - others include alcohol, antifreeze, mercury and oxygen.
- A solution can be saturated but dilute, like a gold ring in a glass of water. When a liquid dissolves in another liquid, it is called miscible rather than
Mixture & solutions ppt
This document discusses mixtures and solutions. It defines matter and explains that mixtures are made of two or more kinds of matter that can be separated using various methods like filtration or evaporation. Solutions are mixtures that form when one material dissolves in another and cannot be separated by filtration. The document provides examples of mixtures like sand and water or iron and sand, and solutions like salt water. It also gives methods for separating different types of mixtures and defines terms like solubility, saturated solutions, concentrated and dilute solutions.
07-Solutions-Solvents-Solutes.ppt
The document defines key terms used to describe solutions:
- A solution is a mixture formed when a solute dissolves in a solvent.
- The solute is the substance that dissolves, while the solvent is the liquid doing the dissolving.
- For a substance to dissolve, its particles must mix homogeneously at the molecular level with the solvent particles, so that the solution appears clear. Undissolved solutes remain visible.

The document discusses several methods for separating mixtures: sieving can separate insoluble objects; filtration uses filter paper to trap insoluble substances from water; decanting allows insoluble substances to settle and pour off the liquid; floatation separates oil from water using a separating funnel; evaporation boils a liquid to separate dissolved solids from the solvent; and distillation separates mixtures based on differences in boiling points such as separating water and salt from salt water.
Separations by Arian, Daniel, Maseeh and Vincent
The document summarizes several separation techniques: filtration, which uses filter paper to separate insoluble particles from liquids; decanting, where a heavy insoluble substance settles and is separated by pouring off the liquid; floatation, where an insoluble substance floats and is separated; evaporation, where a liquid turns to a gas and is separated; and distillation, where a solution is heated to separate components by turning one into a vapor.
Separation techniques by Nikhar, Andrew, Kushal, Tyler, Aaron and Shehan
There are several methods for separating mixtures including sieving, filtration, decanting, floatation, evaporation, and distillation. Sieving separates large insoluble substances from small ones by allowing small particles to pass through the sieve. Filtration uses a filter paper to trap small particles in a mixture and allow liquid to pass through. Decanting involves carefully pouring off liquid from sediment that has settled on the bottom. Floatation separates substances based on differences in density, allowing the less dense substance to rise to the top. Evaporation and distillation both involve heating a liquid mixture so the vapor can be separated and collected, with distillation producing a purer substance.
Teaching experimental design
This document outlines the key components of an experimental design for teaching students, including background research, aim, hypothesis, equipment, variables, results, discussion, and conclusion. It explains that an experiment tests a hypothesis by manipulating an independent variable and measuring its effects on a dependent variable while controlling other influences. Replication, validity, and reliability are also discussed.
Games based learning inspire innovate conference
This document discusses embedding game-based learning in the classroom. It notes that games offer a sense of achievement, teamwork, and learning to overcome problems. The document emphasizes that embedding games is about learning, not just educational games or gamification. It recommends that teachers play games themselves to start small, consult their community, watch related shows, and collaborate with others to incorporate game-based learning.

Students at Merrylands High School created a geolocation game about the school. The game is programmed for mobile devices and was designed for Year 6 students coming to the school in the following year.
The 1:1 journey
The article discusses the trend of 1:1 student to laptop programs in schools. While well-intentioned to prepare students for a digital world, there are concerns that such programs may distract from learning and increase inequality. Research on the educational impact of 1:1 programs remains mixed, with successful implementation depending on how technology is integrated into teaching practices.
Playing.Designing.Learning
Merrylands High School students participated in a program called Laptop LeaDERs where they worked in teams to design and create a video game. The program involved 4 levels - in the first level students began planning their game, in the second level students took on roles as programmers, writers, or media collectors to develop the game, in the third level they completed the game, and in the fourth level they unlocked achievements for their teamwork, problem solving, and self-regulation skills learned through the project.

Hsc physics intro
This document outlines the structure and requirements for the HSC Physics course at Merrylands High School. It discusses that the core modules cover Space, Motors and Generators, and From Ideas to Implementation. Students must also choose one option module such as Geophysics or Medical Physics. It provides guidance on what students need to do to succeed in the course, including checking resources daily, taking notes, doing regular practice questions, and submitting all assessments on time.
Evolution - What do you believe in?
The document is a short quiz about evolution and related facts. It asks the reader to determine whether 7 statements about evolutionary topics like extinct animals, giraffe neck length, Tasmanian tigers, embryo development, wombat size, monotremes, and human-ape relation are true or false. The quiz tests the reader's knowledge on diverse subjects involving how species have changed over time through evolutionary processes.
Cell division
Cell division is the process by which a parent cell divides into two daughter cells. It is needed for growth, repair, and reproduction. During cell division, the DNA in the nucleus must first replicate so that each daughter cell receives a copy. DNA replication ensures each new cell has the same genetic information as the original cell. There are two types of cell division: mitosis, which produces identical daughter cells for growth and repair, and meiosis, which produces sex cells like eggs and sperm with half the number of chromosomes to allow for fertilization.
How the universe began
The document discusses the origins of the universe according to the Big Bang theory. It describes how Einstein identified the equivalence of energy and mass, while Friedmann predicted expanding universe models of closed and open forms. Hubble then observed redshift in nebulae and used this to propose an expanding universe model, developing the Hubble constant to estimate expansion rates. This evidence supports the Big Bang theory of an exploding, expanding universe originating from a hot dense point.

Making mixtures of solids and liquids
- 1. Making mixtures of solids and liquids Aim: To make mixtures of solids and liquids Equipment: 4 test tubes, test tube rack, salt, oil, sugar, copper sulfate Method: 1. Collect all equipment. 2. For the first test tube, half fill the test tube with water and add a pinch of salt. Put your thumb over the opening of the test tube and shake it to thoroughly mix the salt in the water. 3. Did the salt ‘disappear’ into the water? Record the results in the table below. 4. Repeat steps 2 and 3 for the rest of the test tubes and substances. 5. Clean up and put your equipment away. Results: Substance Did it ‘disappear’ in water? salt oil sugar copper sulfate Conclusion: ………………………………………………………………………………………………………………… …………………………………………………………………………………………………………………
- 2. Solutions, solutes and solvents When a solid ‘disappears’ into a liquid, we say the solid has dissolved into the liquid. The solid that does the ‘disappearing’ is called the solute and the liquid is called the solvent. A mixture of a solute and a solvent is called a solution. If the solid doesn’t dissolve into the liquid, the mixture is called a suspension. Here is your results table again. This time you need to identify the solute and the solvent. Substance Did it dissolve What is the What is the Is this mixture in water? solute? solvent? a solution or a suspension? salt flour copper sulfate sand sugar Complete these sentences When a solid ‘disappears’ into a liquid, the solid has …………………… When a solid dissolves into a liquid the mixture is called a ………………………………… When a solid doesn’t dissolve into a liquid the mixture is called a ………………………… In a solution, the solid that has dissolved is called the …………………………..
