Task 10

Materials and tools for a working group:

images of solar collectors (teacher displays for whole class)

In the previous task, pupils found that the amount of electricity produced depends on the angle at which the light falls on the solar cell. In this task, the teacher leads pupils´ attention on how this can affect the usability of solar radiation in solar power plants. Teacher displays pupils a set of solar collectors, preferably real ones in the neighborhood. He discusses (based on the image to task 10) with pupils about why solar collectors are inclined and how it relates to the movement of the sun in the sky during the day. Pupils can formulate their explanations (based on discussion) in their own language 10. The teacher can then discuss with the pupils how fixed solar cells in a power plant can be adapted to capture as much light as possible during the day and transform it into electricity.
