List as many electrical items as you can.

What do they transfer their electrical energy

to?

Aims

• Draw conclusions consistent with the scientific evidence. [Level 5]

• Develop experimental design skills. [Level 6]

• Analyse data in order to justify an opinion. [Level 7]

• Perform multi-step calculations in order to evaluate a process. [Level 8]

1. Why is there a lot of interest in generatingelectricity from the wind?

2. Give a weighting from 0 to 10 for eachopinion on page 122 of the Go Science! 3pupil book for and against wind energy.(10 means you think the opinion is veryimportant, 0 means you think it is notimportant.) Total the scores. Which opinionshave the highest score – for or against?Does this agree with your point of view?

3. The government has decided that windpower is a good idea, but does not want tocover a lot of the countryside with turbines as local people often protest about the damage to views and tourism. Suggest two alternative ideas for the placement of turbines.

Pupils are given a post-it note. They have to write down a final opinion on wind farms with a sentence justifying that opinion. Pin on a wall and read out some of the comments.
