T. 12. THE STATES OF MATTER.
1.- Listen the following song about THE STATES OF MATTER and complete the gaps with the words below:
AIR - WATER – HOT - COLD - SOLID – COULD – SOLID - ENOUGH - GAS - STEAM – WARM - LIQUID – ICE- WOULD - MILK – ROCK - GAS
Solid, ________, Gas
____ is a ______ , _______ is a liquid, _______ is a _____
Rock is a solid ._______ is a liquid. And ______ is a gas
When water's _______ enough, It's a liquid
When it's cold ________ , It's a solid, And when it's _____ enough, It's a gas
So _______ you make the air so ______ it would be solid
Could you make a _______ so warm it would be liquid
Could you make milk so hot it ________ be a gas
______, Liquid, ____
2.- Which one is the solid, the liquid and the gas in the following pictures:
3.- Divide the following words into three groups: solids, liquids and gases.
air – salt – snow - petrol – ice – nitrogen - rock – grass – milk – oil- helium – wood – iron

SOLIDS LIQUIDS GASES
4.- Complete the following summary about CHANGING STATES.
The words are: melting – vaporization – condensation - freezing
5.- When a substance changes from a liquid to a solid or a gas to a liquid, that is called a change of state. Match the types of change in state in the right column with the list of things that occur in everyday life in the left column.
Every day event a. solid to liquid b. liquid to solidc. liquid to gas d. gas to liquid
1. ___ making Jelly2. ___ water in an ice cube turning to ice3. ___ nail polish remover evaporating
4. ___ water droplets forming on the inside of a cold window5. ___ boiling water in a pan fora long time until the water level drops a lot6. ___ butter melting in a pan7. ___ ice cream melting8. ___ pancake cooking9. ___ a bathroom mirror foggingup when someone takes a hot bath or shower
6.- Match the two columns:
Constant shape and volume FUSION
Teaching Unit THE STATES OF MATTER: Leonor María Cosano Jurado
Change from gas to liquid GAS STATE
Constant volume and variable shape SOLID STATE
From solid to liquid SUBLIMATION
Variable volume and shape LIQUID STATE
7.- Watch the following video about the PROPERTIES OF LIQUIDS and answer the questions:
a.- How many does the teacher have? b.- What are they? c.- Which one is the densest liquid?. d.- Has the liquid the shape of the container? e.- Order the four different container, with four different colours, according to their capacity?. f.- What is the meaning of “pour”?.. g.- What materials does she use to see the properties of floating and sinking? h.- Which are the objects that sink into the water? I.- Which are the objects that don´t sink into the water?.
8.- True or False sentences. Correct the false ones.
1.- Solids have a fixed volume and shape.2.- Liquids do not have a shape.3.- Gases have a fixed shape and volume. 4.- Molecules attract each other very strongly in solids.5.- Liquids do not adapt their shape top the receptacle that holds them. 6.- Most of gases are invisible. 7.- Gases do not have mass and weight. 8.- Liquids expand more than gases.9.- Liquids have a constant volume. 10.- The forces of attraction between molecules in gases are stronger than in liquids. 11.- The particles of a liquid are disordered. 12.- The particles of a gas move quickly. 13.- When we touch a pan and we get burnt, the vibration of our skin's particle increases. 14.- When a pan cools down its particles vibrate with less amplitude, that is why temperature drops. 15.- Sea water is a pure substance16.- Tap water is pure substance.
9.- Copy and complete the following statements. The missing words can be found in the word list below.
a) All substances are made of _________________.b) Substances can exist in three different _________________: solid, liquid and
Teaching Unit THE STATES OF MATTER: Leonor María Cosano Jurado
_________________c) A substance has different _________________ in different states.d) _________________ have a fixed volume, a variable shape and are not compressible.e) We can measure volume and _________________very easily.f) Boiling occurs at a particular temperature. _________________ occurs all the time.g) _________________ are formed by evaporation and condensation.h) Water on the Earth changes state all the time– ice, liquid water and water _________________
10.- Complete the sentence: the temperature of an object depends on the movements of its____________, it is measured with a ___________ and it is expressed in units of ___________.
11.- The temperature of a substance at fusion is 20ºC: a.- What state is that substance in if the room temperature is 25ºC?b.- And if the temperature is 15ºC?.
12.- What is the difference between evaporation and boiling?. What change of state does it refer to?.
13.- When we heat water which is at 40ºC, what happens? And what happens if the water is at 100ºC?. Why doesnt the temperature increases?.
14.- Match the two columns. The items on the left can be matched to one or more of the items on the right:
ATOM FeCH4
COMPOUND MgN2
CHEMICAL ELEMENT H2OAg
MOLECULE C6H12O6 (azúcar)
15.- Classify the following materials into PURE SUBSTANCE or MIXTURE:
Teaching Unit THE STATES OF MATTER: Leonor María Cosano Jurado
WATER - SUGAR – GRANITE ROCK - STEEL - CLOUDS – SALT – SOUP – ALUMINUM – AIR – MARBLE – GOLD – FERUM – SEA WATER
PURE SUBSTANCES MIXTURES
16.- Watch the following drawings of different materials and classify them into: PURE SUBSTANCE – ELEMENT PURE SUBSTANCE – COMPOUND MIXTURE
17.- Experiment about Properties of Gases:
We put 2cc of air inside a syringe and we close it by securing it with a rubber top (A)
