1. Wind turbines
The children are required to discuss the positive and negative aspects of using wind turbines and factors that affect their location and design.
Children then design and make a model wind turbine.

2. Discuss photographs of different wind turbines.
General Questions for discussion
Where is this wind turbine located?
Is it by itself?
What is a group of wind turbines called? (wind farm)
What is the significance of being with other turbines?
Are they near buildings?
What are the advantages of being away from buildings?
Do these turbines face in a particular direction?
Why? (prevailing winds)
Is offshore a good location?
How do these wind turbines work?
How do they use the wind?
What are they made from?
Do you think there are any disadvantages to generating energy in this way?
(location of wind turbines, farm land, scenic spots, wildlife).
Name an advantage of this method of generating energy over solar energy (the wind turbines will work both day and night provided there is sufficient wind – solar will only work during the day)

3. General Questions for discussion

9. Design and make a wind turbine
In groups the children make a detailed drawing of an ideal location for a wind turbine in their local area. Encourage each group to discuss factors that need to be considered.
Discussion on elements to be included in the plan
Criteria
In groups, children discuss criteria required to make a wind turbine for a chosen location. Record the children’s ideas and then select 3 or 4 criteria that the children must adhere
to when designing and making their wind turbines.
For example
It must be at least 30 cm high.
It must catch the wind.
It must rotate freely.
All groups should also be aware of the location for which they are designing their turbine.
Materials (activity of selecting materials on next page)
Labelled diagram

10. Selecting materials for the wind turbine
With the aid of class discussion, identify the items you would bring into the circle to make your wind turbine.

11. Resources required
A sheet of paper/ card (to make blades of windmill if not using wood)
Pencil
Scissors
Ruler
Digital camera (for children to record stages in the design and make
process)
Panel pin hammer (available in any DIY store)
Nails (panel pins 25mm)
Coping saw (optional)
Pieces of wood (plywood/ white deal)
Dowelling
Safety goggles
