Back to "the chalk face" and what I love doing most, lessons with children who are up for these challenges. And they certainly were today at Our Lady of Lourdes Primary School, Hanham Road, Kingswood, Bristol. Thank you to head teacher Dave Cahill, his colleagues and pupils, for a thoroughly enjoyable romp through the worlds of visual literacy. I was very impressed with a couple of children that I was honoured to be involved in conversation about some landscapes and the impressions that these places left upon their young minds. They were philosophical about the need to make changes in order to preserve what we have upon this planet, but, they also seemed aware of previous swings and alterations in temperatures that the Earth has experienced. A fine balance between knowledge and an understanding of the importance of effort and change, however small and insignificant it may seem to the one who is "trying". It reminded me of this poignant clock. It is thought provoking and does not give a vast amount of guilt free sunshine, but may be well worth discussing with children.
