Particles & Matter

The particle and kinetic theories of matter can be used to describe the arrangement and motion of particles in a substance, including the attraction between particles, and to explain the properties and behaviour of substances, including melting point, boiling point, density, compressibility, gas pressure, viscosity, diffusion, sublimation, and expansion and contraction.​​​​​​

Observing Particles - Brownian Motion

Brownian Motion

GLOSSARY

Brownian motion is the random, jerky movement of tiny particles (like dust or pollen) when they are floating in a liquid or gas.
 

This movement happens because the invisible particles of the liquid or gas are constantly bumping into the tiny particles and pushing them around.

Brownian motion.png

​​Brownian motion is proof that particles are moving, even if we can’t see them:

  • In 1827, a scientist named Robert Brown looked at tiny pollen grains in water through a microscope.

  • He saw the pollen jiggling and bouncing around.

  • At first, he thought the pollen was alive – but it was actually being hit by invisible water particles!

  • This movement is called Brownian motion.
     

 Brownian motion shows that:

  • Particles are always moving.

  • They can hit and move other tiny particles.

  • The random, jerky movement we see in things like smoke or dust proves particles are real and in constant motion.

Particle Theory

Everything around us is made of tiny particles — they’re like building blocks that are so small we can’t usually see them, even with a microscope.
 

The Particle Model helps us understand how solids, liquids, and gases act. In each state of matter, the particles are arranged differently and move in different ways. Particles are always moving, even in solids where they only vibrate.

The Evolution of the Atomic Particle Model

Particles make up all matter. In science, we often show them as simple spheres, but real particles are much more complex. Our understanding of particles has been developing for over 2,000 years, and the particle model has changed as new discoveries were made.

PhET DIGITAL INQUIRY: The effect of heat of on the motion & energy of particles

​​Matter on Earth commonly exists in three states: solid, liquid, and gas. Some substances, like water, naturally occur in all three. Others can be changed from one state to another through human intervention—for example, turning carbon dioxide gas into solid dry ice. As matter changes state, the particles motion increases or decreases as they gain or lose energy (heat).

PhET: Investigating the States of Matter

ACTIVITY

INSTRUCTIONS: Access the online interactive PhET: States of Matter (Basics). Use the interactive to investigate the effect of heat on the motion and energy of particles in different states of matter. Complete the tasks and questions provided. 

Phase Changes

Phase changes are when a substance changes from one state of matter to another. For example:
 

Melting – Solid turns into liquid (e.g., ice melts into water).

Freezing – Liquid turns into solid (e.g., water freezes into ice).

Evaporation – Liquid turns into gas (e.g., water evaporates into steam).

Condensation – Gas turns into liquid (e.g., steam becomes water droplets).

Sublimation – Solid turns straight into gas without becoming liquid (e.g., dry ice).

Deposition – Gas turns straight into solid (e.g., frost forming on a window).
 

These changes happen when heat is added or removed, affecting how particles move and arrange.

Matter & Phase Change - Visual Summary

ACTIVITY

Compare and contrast the phase changes that lead to different states of matter. Create a visual diagram that summarises these phase changes between solids, liquids and gases.

All substances melt or boil at specific temperatures. Substances have different melting and boiling points because of the strength of the forces between their particles. These forces are called intermolecular forces in liquids and chemical bonds in solids.
 

Melting point: the temperature a solid turns to liquid.
 

Boiling point: the temperature a liquid turns to gas.

[4] Density

Items.png

SINK OR FLOAT?

HOOK

EXAMINE the range of objects provided by your teacher. 
 

PREDICT which objects will sink and which will float in water. 
 

OBSERVE the results by watching your teacher add each of the objects into a large container of water. 

RECORD your predictions and the observed outcomes. 

DISCUSS

Why do some heavier-looking items float and some smaller ones sink?

LEARNING INTENTIONS: 

Explore the relationship between density, the closeness of particles and how this affects whether things sink or float.

SUCCESS CRITERIA: 

  • Explain density using the particle model and the terms mass (how heavy) and volume (how much space it takes).

  • Calculate density using the formula density = mass ÷ volume (d = m ÷ v).

  • Measure and test density by seeing if things sink, float, or stack in water or other liquids.

What is Density?

Density is how tightly packed the particles are in a substance. If particles are close together, the substance is dense. If they are spread out, it's less dense.

We calculate density using the formula:


Density = Mass ÷ Volume

  • MASS = How heavy something is

  • VOLUME = How much space it takes up

Density.png
Density Triangle.png

Density and Archimedes’ Eureka!

 

Archimedes' Eureka! refers to when the ancient Greek scientist Archimedes discovered how to measure volume using water displacement. He realised that when an object is placed in water, it pushes out (displaces) an amount of water equal to its volume — helping him figure out if a crown was made of pure gold. He shouted "Eureka!" meaning "I’ve found it!"

displacement.png

Using a Eureka can to find density:

  1. Fill the can until water drips out, then stop.

  2. Place a measuring cylinder under the spout.

  3. Gently lower the object into the water.

  4. Catch the water that spills out — this is the object’s volume.

  5. Weigh the object to find its mass.

  6. Use the formula: Density = Mass ÷ Volume.

🥼LAB: Density Column Challenge

Part A – Measure Mass and Volume
 

Measure the Mass

  1. Place the substance or object on the electronic balance.

  2. TARE the scale first to ensure accurate measurement (zero the balance before use).

  3. Record the mass in grams (g).
     

Measure the Volume

  1. If it’s a liquid or has a regular shape, use a measuring cylinder to measure the volume in millilitres (mL).

  2. If the object has an irregular shape, use a Eureka can to measure its volume:

    • Fill the Eureka can until it just starts to drip.

    • Carefully lower the object into the water using a string.

    • Collect the displaced water in a measuring cylinder.

    • Record the volume of displaced water (this is the object's volume) in mL.
       

Calculate the Density

  1. Use the formula: Density = Mass ÷ Volume (d = m / v)

  2. Record the density in g/cm³ (note: 1 mL = 1 cm³).

  3. Repeat for each item or substance.

Part B – Create a Density Column

  1. Using the densities you calculated, order each liquid and object from least to most dense.

  2. In a clear cylinder or jar, carefully pour each liquid in order from most dense (bottom) to least dense (top). Pour slowly over a spoon or down the side to prevent mixing.

  3. Gently drop solid objects into the column and observe where they settle. They will float or sink to the layer that matches their density.

 

Observe and Record

  • Sketch or photograph your density column.

  • Label each layer and object with its name and calculated density.

Calculating Density

ACTIVITY

INSTRUCTIONS: In this task, you will measure and calculate the density of different materials using the formula:

 

Density = Mass ÷ Volume (d = m / v)

 

You will then use this data to create a density column where substances are correctly layered based on density.

LEARNING INTENTIONS: 

Explore the relationship between the particles in liquids and their viscosity. 

SUCCESS CRITERIA: 

  • Define viscosity and give real-life examples.

  • Use particle theory to explain why some liquids flow faster than others.

  • Measure and compare the flow rate / drop rate of different liquids.

  • Record and analyse data to support my conclusions.

Viscosity of Fluids

Factors that make fluids more viscous
 

1. Cold temperatures – Liquids usually become thicker and flow slower when they are cold.
 

2. Large or oddly shaped particles – These can slow down the flow because they bump into each other more.
 

3. Sticky particles – If the particles in a liquid stick together strongly (due to intermolecular forces), the liquid flows more slowly.
 

4. More stuff mixed in – When a liquid has a lot of things dissolved in it (like sugar in syrup), it becomes thicker and flows slower.

Viscosity

GLOSSARY

Viscosity means how thick a liquid is and how easily it flows.

  • High viscosity liquids (like honey) are thick and flow slowly.

  • Low viscosity liquids (like water) are runny and flow quickly.

ants_edited_edited.jpg

🥼LAB: Comparing Liquid Viscosities

Students were interested in testing the viscosity of different liquids. To investigate this, they collected six large cylinders and filled each with equal volumes of different liquids: water, vegetable oil, honey, dish soap, salt water and shampoo. 
 

Next, they dropped a marble into each cylinder of liquid and measured how long it took for the marble to reach the bottom. The time taken was used to compare the viscosity of each liquid — the slower the marble moved, the higher the viscosity.

[6] Expansion, Contraction + Compression

Observe the classic ball & ring experiment

  3. What does it make you THINK?
     

  4. What do you WONDER? 

LEARNING INTENTIONS: 

Understand how heating, cooling and pressure affects the distance between particles in solids, liquids, and gases.

SUCCESS CRITERIA: 

  • Describe why solids expand when heated and contract when cooled using the particle model.

  • Describe how applying pressure changes the spacing between particles, especially in gases.

  • Explain how expansion, contraction, and compression of particles influence the design of everyday objects.

  • Compare contraction, compression and condensation.

Expansion & Contraction of Particles

 

When a solid is heated, its particles gain energy and vibrate more, causing them to move slightly further apart — like people in a mosh pit who are active, spread out, and taking up more space. This results in expansion.

 

When a solid is cooled, the particles lose energy, vibrate less, and move closer together — like a quiet, seated crowd where everyone stays still and close. This leads to contraction.

Ball & ring_edited.jpg

NOTE

⚠️ Expansion and contraction do not mean the particles themselves get bigger or smaller — just the space between them changes.

​​The ball and ring experiment demonstrates this: heating the metal ball makes its particles behave like a mosh pit, expanding the ball so it no longer fits through the ring; cooling it again causes contraction, allowing it to pass through.

Particle motion.gif

If particle were like a crowd of people at a concert...

slow crowd.jpg

Less energy = closer together

Mosh pit.png

More energy = further apart

Expansion + Contraction in Everyday Life

Students in science class regularly make the mistake of running hot glassware (i.e. a beaker) under cold water at the end of an experiment. This sudden change in temperature causes the outer surface of the glass to cool and contract quickly, while the inside remains hot and expanded. The uneven contraction puts stress on the glass, which can lead to cracking or even shattering.

That Sweet Perfume Smell...

HOOK

DEMO: Your teacher will spray perfume in one corner of the classroom.
 

BEFORE: Predict what will happen when your teacher sprays the perfume. Will everyone smell it at the same time? Why or why not?

DURING: Raise your hand as soon as you can smell the perfume. What do you notice about how long it takes different people to smell it?

perfume.jpg

LEARNING INTENTIONS: 

Understand how diffusion happens and why it occurs.

SUCCESS CRITERIA: 

  • Define diffusion. 

  • Use the particle model to explain how diffusion works in fluids (gases + liquids) 

Diffusion

Diffusion is the movement of particles from an area of high concentration to an area of low concentration. It happens because particles are always moving and bumping into each other, causing them to spread out. Diffusion doesn’t need any added energy—it happens naturally due to the motion of particles.
 

It can occur in gases, like when perfume spreads through the air, or in liquids, like when food colouring spreads in water. In solids, diffusion is much slower because the particles are tightly packed and can only vibrate in place. However, over a long time and especially at higher temperatures, some particles (like atoms) can slowly move through a solid. This is still diffusion, but it’s much less noticeable than in gases or liquids.

Particle Diffusion

[8]  Sublimation

Dry Ice vs. Lava - which will win?

HOOK

1) What did you observe happening when the lava touched the dry ice? Was your prediction correct? Explain.
 

2) How did the rock (lava) change state during the video? What caused these changes?

3) The dry ice produced thick "steam" or fog during the reaction. What do you think caused this effect? 

​​

LEARNING INTENTIONS: 

Understand the phase changes sublimation & deposition. 

SUCCESS CRITERIA: 

  • Define sublimation and deposition. 

  • Observe the sublimation phase change of dry ice. 

Sublimation & Deposition

Sublimation is when a solid turns straight into a gas without turning into a liquid first.
Deposition is the opposite – it’s when a gas turns straight into a solid without becoming a liquid.
 

An easy example of sublimation is dry ice. Dry ice is the solid form of carbon dioxide. When you leave it out at room temperature, it doesn’t melt into a liquid like ice does. Instead, it turns straight into carbon dioxide gas. That’s why it looks like it’s “smoking” – the fog you see is actually water in the air condensing because of the cold gas.
 

An example of deposition is frost. On a really cold morning, water vapor in the air can change straight into ice crystals on a surface like a window or grass. It skips the liquid stage and goes straight from gas to solid.

Observing the Sublimation of Dry Ice

Dry ice is frozen carbon dioxide (CO2). ​A block of dry ice has a surface temperature of -78.5°C ​(it can cause severe burns due to frostbite). ​Dry ice sublimates directly into carbon dioxide gas rather than a liquid ​(it requires high pressure to change into a liquid state).​

Dry Ice Sublimation
