One of the topics we are covering as part of the British Council’s Connecting Classrooms program is food webs which was suggested by Mr Thembo, the headteacher of Kafuro Primary School.
Steve Peach very kindly produced a PowerPoint which took the children through the differences between food chains and food webs. Mr Stanley was very impressed with the children’s knowledge of food chains and the terms producer, consumer and predator. Only one pupil in the class had a good idea about what a food web is, so Mr Stanley was able to use the PowerPoint (displayed below) to show some examples of food webs in both UK and Uganda.
Once the children had got used to the idea of what a food web meant, we created our own using animals commonly found in the UK
We then went onto the playground with a big ball of string in order to try and replicate this food web. The photos below make it look as if we were actually quite successful. However, the complexity of the food web meant that we actually ran out of string before we could complete it.
Our final discussion of the session was based around what might happen to the food web if one of the elements was removed from it. We discussed several possibilities, but the children concluded that if the frog was removed from our food web then much of the web could collapse. Clearly removing land plants or water plants would have a massive effect on the ecosystem. When you think about the damage this would cause and then compare it to vast deforestation taking place on our planet, it makes you wonder whether humans are actually very clever at all!
We are looking forward to seeing what food webs other schools in the twinning project produce.
