LANGUAGE HELP
You need to use the
same auxiliary verb in
questions and answers.
Examples:
- Did you go to the
dentist yesterday? Yes, I
did. / No, I didn’t.
- Do you clean your
teeth every day? Yes, I
do. / No, I don’t.
- Can you swim? Yes, I
can. / No, I can’t.

7. a. Did you use energy when you sat down in your chair?
b. Did you use energy when you opened your eyes in the
morning?
c. Did you use energy when you were sleeping last night?
d. Do rivers use energy when their water is flowing?
e. Did your chocolate powder (Cola Cao) use energy to get
dissolved in the milk?
f. Can you do anything without energy?
Numbered heads together. Listen, think in groups and answer.

8. PROPERTIES OF ENERGY
- Energy can be ____________ from one form to another. For
example, electrical energy is converted into light energy.
- Energy can be ____________ from one body to another. For
example, when you shoot a ball, the mechanical energy in
your foot passes to the ball so it moves.
- Energy can be ____________. For example, batteries have
chemical energy to be used later.
- Energy can be ____________ from one place to another. For
example, electrical energy is ____________ through electric
cables.
Individual work. What are the properties of energy?
1
transported – stored – transformed – transferred – transported

9. Jigsaw technique. Make groups of experts to find as much
examples as possible for each property of energy.
1
Energy can be transformed Energy can be transferred
Energy can be stored Energy can be transported

11. Energy comes from a lot of sources, which can be categorized into two
groups: non-renewable and renewable.
Oral presentation. In groups, draw a diagram on energy
sources and prepare a 4-minute presentation. Everybody must participate.
Use linkers and be engaging!
2
These energy sources
can be replaced quickly.
Wind turbines
transform the
mechanical
energy into
electrical energy.
WIND ENERGY
This is the mechanical energy of
moving water. We can produce
electrical energy
using water
falling from a
reservoir or the
tides of the sea.
HYDROELECTRIC ENERGY
The chemical energy of organic
waste from plants or from
animals, like
excrement, is used
to generate heat or
electrical energy.
BIOMASS
The Sun emits energy as
light and heat. Solar panels
take this
energy and
transform it into
electrical
energy.
SOLAR ENERGY

12. Oral presentation. In groups, draw a diagram on energy
sources and prepare a 4-minute presentation. Everybody must participate.
Use linkers and be engaging!
2
These energy sources are
used faster than nature can
produce them.
Petroleum, coal,
natural gas, etc.
are fossil fuels.
They have
chemical energy
and it can be
transformed into
electrical and
thermal energy.
FOSSIL FUELS
Uranium and
plutonium are nuclear
fuels. These elements
have nuclear energy
and we transform it
into heat and
electrical energy.
NUCLEAR FUELS

13. Materials:
- Pringles can
- Scissors
- Cling film
- A skewer
- A sausage
Steps:
1st Get the Pringles can and cut a rectangular hole.
2nd Cover the hole with cling film.
3rd Make a hole on both sides of the Pringles can to pass the skewer through
them.
4th Put a sausage on the skewer and place it in the Pringles can.
5th Put the container in a sunny place, and wait. The sausage can take 1 hour
or 1 hour and a half to cook.
Read the instructions and make a solar cooker at home. Later, cook
a sausage in it and send a picture of your solar cooker to your teacher.
You can also print the picture.

15. Energy provides us with modern comfort. However, energy use has a lot of
negative consequences:
- Fossil fuels are limited resources. One day, we will not have them.
- Nuclear fuels produce radioactive waste, that is toxic to living things.
- Fossil fuels produce toxic substances, causing air pollution. If there is much
air pollution, we will have acid rain, that is very bad for plants and aquatic
animals.
- Burning fossil fuels also cause global warming. It is because greenhouse
gases, like CO2, absorb the heat, so the Earth gets hotter and hotter.
Saving energy is good for the planet, so we can:
- Reduce the temperature of heaters.
- Walk, ride our bikes or use public transport.
- Take showers instead of baths.
- Turn off the lights and machines when not in use.
- Practise the 3 Rs: Reuse, Reduce and Recycle.
Cooperative board game. Read and understand. Later, play this
board game cooperatively. The winner group will get 3 positive points.

19.  Sound is a type of energy made by vibrations. When an object
vibrates, it causes sound waves that travels through the air.
 Sound is a type of energy made by electricity. When an object
makes a sound, it causes an electric current that travels
through the air.
1-2-group. Tick the correct definition of sound and cross the
wrong one. Later, watch the video and check.

What is sound? Extension video:
Transmission of
sound
Information in
Spanish: El oído y
la audición

20. There are many different sounds. To distinguish them, we need
to pay attention to their properties:
- Volume: It shows if a sound is loud or quiet.
- Pitch: It indicates how low or high a sound is. For example,
normally female voice is high and male voice is low. Musical
notes belong to sounds from low to high pitch.
- Timbre: It’s the particular quality of each sound. We
distinguish sounds with the same volume and pitch thanks to
timbre. Everybody has a different timber in his/her voice.
Thinking twins. Listen and classify the sounds according to their
properties. First, read cooperatively to know them well.

- Rubber band
- Salad bowl
- Wooden spoon
- Metal tray
- Sugar
Cooperative summary. Carry out the following experience
and, later tell your teacher what you have learnt. We will write all your
contributions on the board to get and excellent summary.

Steps:
1st Use the rubber band to cover the
salad bowl with cling film.
2nd Spread sugar all over the cling film.
3rd Hit the metal tray with the wooden
spoon.
Make sugar
dance without
touching it

23. Materials:
- Two plastic/yoghurt cups
- Drawing pin
- Wool string
- Toothpicks
Steps:
1st Make a hole in the bottom of each yoghurt cup using the
drawing pin.
2nd Use a pencil to make the hole bigger.
3rd Thread the end of the string through one of the holes. Tie a
large knot or attach a toothpick to stop the string falling back
through.
4th Repeat with the other cup.
Class experience. Follow the instructions to make a yoghurt-pot
telephone.

25. Noise pollution refers to sounds that can be harmful (bad) for
people and other living things.
Debate. Read, look at the graph and debate on this question: Is
noise pollution really a type of pollution?
