“Exploring the material world” Air as a source of energy Teaching kit “Exploring the material world” Air as a source of energy

Air as a source of energy… The different aspects of the discovery of the material world can only be approached from real-life situations and observation satisfying children’s curiosity.

Activity 18: Air as a source of energy This activity can be performed with the help of an adult.

Activity 18 : The wind turbine “Exploring the material world”: Air as a source of energy Sheet n° 18 Activity 18 : The wind turbine 4,5 V Air as a source of energy

Air as a source of energy “Exploring the material world”: Air as a source of energy Sheet n° 18 - Tell what you see in the picture… (while showing the cloud and the wind turbines) 4,5 V Air as a source of energy

At nursery school, the important thing is that children should identify and name what they see.

Questions to ask the child: Do you know what a wind turbine is for? Expected answer: “to produce energy”

The mediator will ask the child to turn the sheet over and will suggest making a “windmill”…

Cut along the black lines Exploring the material world”: Air as a source of energy Sheet n° 18 Activity 18 : The wind turbine Fold the corners of the blades and turn them towards the middle 4,5 V Cut along the black lines Stick the pin in the straw and bend it downwards to secure it Secure the blades by sticking the pin in the centre

Fold the corners of the blades and turn them towards the middle Exploring the material world”: Air as a source of energy Sheet n° 18 Fold the corners of the blades and turn them towards the middle 4,5 V

Secure the blades by sticking the pin in the centre Exploring the material world”: Air as a source of energy Sheet n° 18 Secure the blades by sticking the pin in the centre 4,5 V

Stick the pin in the straw and bend it downwards to secure it Exploring the material world”: Air as a source of energy Sheet n° 18 Stick the pin in the straw and bend it downwards to secure it 4,5 V

How does a wind turbine work Exploring the material world”: Air as a source of energy Sheet n° 18 How does a wind turbine work Light bulb Wind turbine Electric wire 4,5 V Generator

- Describe what you see in the picture… Exploring the material world”: Air as a source of energy Sheet n° 18 - Describe what you see in the picture… (while showing the wheel which has just been made) Light bulb Wind turbine 4,5 V Electric wire

Observe carefully how the power is supplied Exploring the material world”: Air as a source of energy Sheet n° 18 Observe carefully how the power is supplied Wind turbine Generator

Questions to ask the child: To understand how a generator manages to supply electricity, look what it is made of inside. Compare with the battery. Does it have the same components inside?

Exploring the material world”: Air as a source of energy Sheet n° 18 Generator 4,5 V Coil Magnets

Exploring the material world”: Air as a source of energy Sheet n° 18 Generator The mediator will ask the child to look closely at the generator and will help him/her to identify… 4,5 V Magnets Coil

When the coil rotates between the magnets, Exploring the material world”: Air as a source of energy Sheet n° 18 Generator When the coil rotates between the magnets, 4,5 V - It produces electricity Magnets coil

When the coil rotates between the magnets, Exploring the material world”: Air as a source of energy Sheet n° 18 Generator When the coil rotates between the magnets, A source of energy is needed 4,5 V Magnets Coil

When the wind blows, it makes the windmill go round Exploring the material world”: Air as a source of energy Sheet n° 18 Generator When the wind blows, it makes the windmill go round 4,5 V - This causes the coil to move between the magnets If the lamp is connected to the generator by electric wires - The lamp will be supplied with electricity

- This energy is renewable Exploring the material world”: Air as a source of energy Sheet n° 18 Generator - This energy is renewable 4,5 V - It does not run out like the battery

Observation and description are the opportunity to draw attention to the functions of the different components of an electric circuit…

A lot of wind is necessary to produce wind power Exploring the material world”: Air as a source of energy Sheet n° 18 A lot of wind is necessary to produce wind power 4,5 V Air as a source of energy Wind power is a renewable, environmentally friendly form of energy

Making a notebook with the children They will be able to record each stage with drawings and photos illustrating what they have learnt from the experiment

The written recording of observations (dictated to an adult) helps to memorise knowledge, become aware of relationships in space and time and identify causal links.

the child should be able to… On completion of the activity the child should be able to… recognise a wind turbine and its usefulness, - make a simple windmill from a plan, with adult help, - recognise a generator and its usefulness - make a simple circuit using a wind turbine
