Learning Goal
Success Criteria
Things to do
To learn about the equipment used in a laboratory.
-Can I name all of the equipment?
-Can I draw all of the equipment in the proper scientific method?
Scientists have a specific set of tools that no other profession uses and a specific way of drawing them.
You should know the use, what they are made of, safety concerns and how to scientifically draw the following equipment: beaker, test tube, conical flask, boss head, clamp, retort stand, heat mat, bunsen burner, tripod, gauze mat, watch glass, evaporating dish.
Download the following worksheet and fill in the names of the equipment, complete a scientific picture of it, then list what it is made of and any safety considerations that you should be aware of when using the equipment.

This website will help you to identify equipment and it's uses. Lab equipment

This website below can be used to find out how to draw scientific diagrams of some of the equipment you will be using in the laboratory.
Scientific drawings
To reinforce our knowledge of scientific equipment and laboratory safety rules.
-Do I understand the correct way to behave in a laboratory and why?
-Can I name all of the science equipment?
As a scientist you need to be able to name all of the equipment that you are using. This is to minimise the confusion in the lab (it is easier for you to ask for a conical flask, than to ask for that bottle thing shaped like a sort of pyramid...)
Download the following worksheet and fill in the answers.
This website will help you to find some of the answers if you get stuck. Lab equipment

To reinforce our understanding of the safety rules and regulations of the laboratory.

-Am I aware of the safety rules and regulations of the classroom?
-Do I understand why they are in place?
-Will I follow them?
A science lab is a dangerous place. It can contain chemicals that may be dangerous and there is lots going on.
You need to be aware of the safety rules and regulations because not following the correct procedures could result in you, or one of your peers, getting hurt.
You should review the list of Student Safety Rules in the front of your practical booklet.
Watch the following videos.

Download the following worksheet and answer the questions.

On the worksheet from last lesson, can see how many of the situations you can identify as right or wrong.
To understand the hazard symbols in the lab and what they mean.
-Am I aware that different symbols mean different hazards?
-Am I able to identify some of the warnings for most labels?
All substances in the lab that are dangerous will have hazard labels attached to them. These hazard labels have different meanings and often give a warning about what the effects of a chemical can be.
Download the following worksheet. Can you identify the symbols? Write your guess in the first column.
The answers for you to correct your guesses with are attached below.

To explore the parts of the Bunsen Burner and how to light one.

-Am I able to name the parts of the Bunsen Burner?
-Am I able to describe what each part is used for?
-Do I understand the process used to light a Bunsen Burner?
The parts of the Bunsen Burner are all very important and have distinct functions.
It is important that you are able to light the Bunsen Burner in the correct way. Failure to do this might result in harm to yourself or others.
Discover and name the parts of the Bunsen Burner and list the uses for each part.
label the bunsen burner

Using the following interactive activity, discover and list the steps used to light a Bunsen Burner.
Practice lighting a Bunsen Burner

Download, print and then cut and paste the following pictures and sentences in the correct order of how to light a Bunsen Burner.

To apply our knowledge of Bunsen Burner to achieve our Bunsen Burner Licence
-Am I able to light a Bunsen Burner correctly?
Sit your theory and practical test to achieve your Bunsen Burner Licence.
Don't forget to study!
You will need to know the parts of the Bunsen Burner, the steps of how to light a Bunsen Burner and how to be safe when using a Bunsen Burner.

You can practice with these activities: label the bunsen burner and

To discover the pysical properties of solids, liquids and gases.
-Can I distinguish between solids, liquids and gases?
-Can I list the physical properties of them?
Solids, liquids and gases have distinctly different physical properties.
Be a Fact Finder and find the physical properties of solids, liquids and gases in your textbook.

Line them up in a table in your workbook.
To investigate how solids, liquids and gases behave.
-Am I able to state the properties of solids, liquids and gases?
Solids, liquids and gases have different physical properties. Investigate these!
We will complete an investigative prac in class involving solids, liwuids and gases and what youa re able to do to each one.
You will be making observations about each state of matter so you must be accurate and make careful observations while you are conducting your activities.
Make sure you have the questions completed by next lesson!
To link matter behaviour to particle arrangement.
-Am I able to explain what the Particle Theory of Matter means?
-Am I able to explain how the particles in the states of matter are arranged?
-Can I explain
The Particle Theory of Matter states that all matter is made of particles.
Particles are tiny round balls that make up everything.
If solids, liquids and gases behave the way they do, how must their particles be arranged?
Draw your guesses of how particles are arranged in solids, liquids and gases.

Investigate the particles in solids liquids and gases using these activities:
The Particle Model
The Particle Model 2

Were your guesses correct? If not, what do you need to change about them to make them correct?

1) Draw a picture showing the particle arrangement in solids, liquids and gases.
2) Describe the movement of the particles in each state of matter.
3) What types of bonds do the particles have in each state of matter?
4) Describe how the particles and bonds in the states affect how the states of matter behave.

To investigate expansion and contraction of solids, liquids and gases.
-Did I complete the prac to the best of my ability?
-Can I explain how energy changes the way particles behave?
Adding energy to particles makes them behave differently.
Watch the following videos and fill in the observation parts of your prac manual. What do you notice about what's happening? How can you explain this using particles?

Can you name each of the states of matter that the following objects are in?
Can you name each of the states of matter that the following objects are in?

Solids, liquids and gases all have different particle structures.
-The particles in a solid are tightly packed together and only move a little.
-The particles in a liquid ar still help together but can move a about. They can slide over each other.
-The particles in gases are free to move wherever they like.

Watch the clip below to learn more about solids, liquids and gases and the picture next to it shows how their particles are arranged.

Diffusion is the movement of particles from an area where they are in a high concentration, to an area where they are in a low concentration. The aim of diffusion, is to make all of the particles evenly spread around. How quickly this happens is called the Rate of Diffusion and this depends on things like the temperature.

Your experiment at home requires you to know about diffusion. If you need another copy of the project sheet you can find it here.

How do substances change state?
Investigate state changes here in a real-life situation.
When substances frome each change state, they must change structure and these changes have names.
Can you sort the correct names from the incorrect names?
Can you place the terms in the correct spots?
Do you remember what the names of the processes are called? Can you draw a diagram of these changes? There are two at the bottom of the page if you would like to check yours, or if you cannot remember how to do this and want a hint.

If you want to revise, check out this page, the words to the song and the clip at the bottom...
