Here comes the sun
Overall learning objectives:
Gathering and tabulating data, manipulating it to support analysis and applying
it to justify arguments.
Understanding the process of energy transfer, explaining the operation of
internal combustion and photovoltaic cells and applying understanding to
propose how clean technologies can be promoted.
Understanding technical and social systems, comparing alternative solutions
and evaluating their fitness for purpose.

Abuja – My City
Why does Buma need to consider alternative energy supplies?
What are the advantages and disadvantages of the petrol generator?
What are the advantages and disadvantages of the photovoltaic?
What would you do in his place, and why?

Storing energy
How is energy stored in a petrol generator? How effective is this and how
safe is it?
How could energy from a photovoltaic cell be stored and how practical is this
in terms of powering the laptop and the mobile phone?
How could this work if the system is scaled up to run appliances such as room
heaters?

Here comes the sun
How should electricity be produced?
Working in groups, identify:
The advantages offered by photovoltaic cells
The kinds of situations in which they are particularly useful
How they could be used more widely in situations such as Abuja
Now prepare a presentation, lasting no more than 60 seconds, which could
be used to persuade people such as Buma to give photovoltaic cells a greater
role.
