All objects around us, such as your body or the stars, have
electrical charges.
- Types of electrical charges:
Objects around us usually have the same number of positive and
negative charges, so they are electrically neutral.
Positive
Negative (This moves from place to place)
Work in groups. Read and make blue and red paper balls.
1
Team work. Listen to your teacher and make positively charged
objects, negatively charged objects or electrically neutral objects.
1
- In your object, three negative charges (electrons) are moving
around while only two positive charges are found in it.
- In your object, you can find seven protons (positive charges)
and you can see that four electrons are moving around.
- One electron is moving and one proton isn’t moving.
- Make a positively charged object and explain why it is so.
- Make an electrically neutral object and explain why it is so.
- Make a negatively charged object and explain why it is so.
Team work. Listen to your teacher and make positively charged
objects, negatively charged objects or electrically neutral objects.
In general, objects are electrically neutral because they have no
charges in them.
Is the following statement true or false? Explain why.

Work in pairs. Follow your teacher’s instructions to do an
experiment with two balloons, string and a cloth. Explain the results.
Work in groups. Follow these instructions and write about the
results of this experiment.

- Objects with the same charge repel.
- Objects with opposite charges attract.
Look at these pictures, watch these videos and write about
how you can use this in your invention.

Electricity in an
electric current can
be transformed into
other forms of
energy.
Read, look, watch the video and discuss.

Materials can be:
- Conductors: Electrical charges can move freely through
these materials.
- Insulators: Electrical charges can’t move through these
materials.
Read and write a list of three conductors and three insulators.

Water is also a conductor of electricity. People are made up
mainly of water, so we are conductors of electricity too. For this
reason, it can be very dangerous to use electrical appliances
near water.
When you are going to use an electrical appliance, make sure
that you, the appliance and everything around you are all dry.
Cooperative reading. Read and speak about security at home.
1-2-group technique. Match each part of an electric circuit and
their definitions.
3
This provides the electricity. The electrical charges go from one
terminal to the other.
This transforms the electrical energy into other type of energy,
such as kinetic or light energy.
Cables transport the
electricity. They are
connecting wires, usually
made of copper, wrapped
in plastic covering.
It controls the flow of electricity by closing or opening the circuit.

A lot of electrical appliances are connected to the electrical grid
through a socket. Every socket is connected by cables to a
national grid.
A national grid gives you the electricity created in power plants.
Read. Where does electricity come from?
4
In groups, write a list of appliances connected to the electrical grid.
The group with the longest list wins.

Read and say if these power plants practise sustainable
development.
Fossil fuels, uranium or
plutonium are used to
heat up the water. This
produces steam, that
moves a turbine which is
connected to a
generator. (Click image to watch video)
Wind moves a
turbine which is
connected to a
generator.
Water moves a
turbine, which is
connected to a
generator.
Heat or light from
the Sun heat water.
The water boils and
produce steam, that
moves a turbine.

BLACKOUT!
At this moment, there is a big storm in Carmona. Lightning is lightning up
the sky, and thunder is roaring above the city. Finally, the storm has caused a
blackout, making Carmona go dark.
Some children are scared. Most of children are lightening some candles
and turning on their torches. We are having lots of fun! But Pepito isn’t…
Feeling better, Pepito is trying to turn on the TV, bit it doesn’t work. He
soon realizes that many other things don’t work without electricity. His
tablet’s battery has run out and there is no way to charge it. Life without
electricity is definitely different…
As there’s nothing we can do about it, Pepito is reading a book by the
light of a torch. Finally, Pepito is enjoying the blackout!
1. What is a blackout?
2. What caused the blackout in Carmona?
3. What electrical device is working during the blackout? How?
4. How is Pepito feeling in the end?
5. Draw a circuit diagram of Pepito’s torch.
Read and answer.

A magnet is an object that attracts other objects made of
magnetic metals.
This attraction is called magnetism.
Magnets have two areas, called poles:
- Opposite poles attract.
- Same poles repel.

Presentation - Electricity and Magnetism

  • 2.
  • 3.
  • 4. 1 All objects around us, such as your body or the stars, have electrical charges. - Types of electrical charges: Objects around us usually have the same number of positive and negative charges, so they are electrically neutral. Positive Negative (This moves from place to place) Work in groups. Read and make blue and red paper balls.
  • 5. 1 Team work. Listen to your teacher and make positively charged objects, negatively charged objects or electrically neutral objects.
  • 6. 1 - In your object, three negative charges (electrons) are moving around while only two positive charges are found in it. - In your object, you can find seven protons (positive charges) and you can see that four electrons are moving around. - One electron is moving and one proton isn’t moving. - Make a positively charged object and explain why it is so. - Make an electrically neutral object and explain why it is so. - Make a negatively charged object and explain why it is so. Team work. Listen to your teacher and make positively charged objects, negatively charged objects or electrically neutral objects. In general, objects are electrically neutral because they have no charges in them. Is the following statement true or false? Explain why.
  • 7. 1 Work in groups. Follow these instructions and write about the results of this experiment.
  • 8. 1 Work in pairs. Follow your teacher’s instructions to do an experiment with two balloons, string and a cloth. Explain the results. Work in groups. Follow these instructions and write about the results of this experiment.
  • 9. 1 - Objects with the same charge repel. - Objects with opposite charges attract. Look at these pictures, watch these videos and write about how you can use this in your invention.
  • 10.
  • 11. 2 An electric current is the flow of electrical charges through materials. Electrical charges Strong electric current Electricity Electricity in an electric current can be transformed into other forms of energy. Read, look, watch the video and discuss.
  • 12. 2 Materials can be: - Conductors: Electrical charges can move freely through these materials. - Insulators: Electrical charges can’t move through these materials. Read and write a list of three conductors and three insulators.
  • 13. 2 Materials can be: - Conductors: Electrical charges can move freely through these materials. - Insulators: Electrical charges can’t move through these materials. Read and write a list of three conductors and three insulators. Water is also a conductor of electricity. People are made up mainly of water, so we are conductors of electricity too. For this reason, it can be very dangerous to use electrical appliances near water. When you are going to use an electrical appliance, make sure that you, the appliance and everything around you are all dry. Cooperative reading. Read and speak about security at home.
  • 14.
  • 15. 1-2-group technique. Match each part of an electric circuit and their definitions. 3 This provides the electricity. The electrical charges go from one terminal to the other. This transforms the electrical energy into other type of energy, such as kinetic or light energy. Cables transport the electricity. They are connecting wires, usually made of copper, wrapped in plastic covering. It controls the flow of electricity by closing or opening the circuit.

  • 17. 3 Explain to your partner what the difference between an open and closed circuit is.
  • 18.
  • 19. 4 A lot of electrical appliances are connected to the electrical grid through a socket. Every socket is connected by cables to a national grid. A national grid gives you the electricity created in power plants. Read. Where does electricity come from?
  • 20. 4 In groups, write a list of appliances connected to the electrical grid. The group with the longest list wins. A lot of electrical appliances are connected to the electrical grid through a socket. Every socket is connected by cables to a national grid. A national grid gives you the electricity created in power plants. Read. Where does electricity come from?
  • 21. 4 Read and say if these power plants practise sustainable development. Fossil fuels, uranium or plutonium are used to heat up the water. This produces steam, that moves a turbine which is connected to a generator. (Click image to watch video) Wind moves a turbine which is connected to a generator. Water moves a turbine, which is connected to a generator. Heat or light from the Sun heat water. The water boils and produce steam, that moves a turbine. THERMAL POWER PLANTS WIND POWER PLANTS HYDROELECTRIC POWER PLANTS SOLAR POWER PLANTS
  • 22. 4 Debate. Divide the class into four groups and each group will belong to a power plant. Which one causes the most pollution? THERMAL POWER PLANTS WIND POWER PLANTS HYDROELECTRIC POWER PLANTS SOLAR POWER PLANTS
  • 23. 4 BLACKOUT! At this moment, there is a big storm in Carmona. Lightning is lightning up the sky, and thunder is roaring above the city. Finally, the storm has caused a blackout, making Carmona go dark. Some children are scared. Most of children are lightening some candles and turning on their torches. We are having lots of fun! But Pepito isn’t… Feeling better, Pepito is trying to turn on the TV, bit it doesn’t work. He soon realizes that many other things don’t work without electricity. His tablet’s battery has run out and there is no way to charge it. Life without electricity is definitely different… As there’s nothing we can do about it, Pepito is reading a book by the light of a torch. Finally, Pepito is enjoying the blackout! 1. What is a blackout? 2. What caused the blackout in Carmona? 3. What electrical device is working during the blackout? How? 4. How is Pepito feeling in the end? 5. Draw a circuit diagram of Pepito’s torch. Read and answer.
