Air as a source of energy

2. 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.

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

4. Activity 18 : The wind turbine

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

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

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

9. Cut along the black lines

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

Generator

17. 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?

18. 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

23. - This energy is renewable

Generator
- This energy is renewable
4,5 V
- It does not run out like the battery

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

25. A lot of wind is necessary to produce wind power

Air as a source of energy
Wind power is a renewable, environmentally friendly form of energy

26. 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

27. 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.

28. 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
