River Ecology on the Itchen
Today, as part of their post-exam Science programme, 8W spent some time on the stretch of the Itchen that runs through the school grounds.
Using biological sampling techniques, known as kick nets, the boys were able to collect some invertebrate samples (and a few bullhead fish!). They were given a lesson on the lifecycles and adaptations of these beautiful, yet alien-looking creatures which call our small chalk stream their home (habitat).
Four of our best biologists from 8W (Harry, Fraser, Henry and Zander) joined 4H science lesson after lunch to use their knowledge to teach the boys about our river's ecology. Some fascinating organisms, such as caddis fly larvae, create their homes by sticking bits of stone and sand to themselves to make a makeshift shell. Large amounts of mayflies were also caught, which are biological indicators that the water going through our school is healthy and highly oxygenated.
Bertie was our fish whisperer, catching eight bullhead fish.
