Water Worlds

This week we’ve been investigating the different habitats around our school. We started by finding out about the different scales of habitats…From under a rotten log and inside walls to a whole mountain or lake! We’ve got tonnes in our school grounds – especially with the new piles of mud (The house martins are LOVING gathering up easy mud for their nests!) We decided to take advantage of having access to our village stream through the bottom field, and decided we wanted to find out if species would be the same in our school pond and the Nant Cwy. Most of us predicted that the animals in the stream would need to be bigger and stronger in order to cope with the flow of the water. First we started by pond dipping then using reference books and scientific keys to identify the vertebrates and invertebrates that we found. We recorded our results on a tally chart.

Whilst some groups were studying and recording the pond life in our wildlife area the others were practicing their close scientific observation and mm measurement skills by drawing the new spring flowers. We needed to carefully observe the exact shape and number of leaves and petals. It was very tricky!

Next stop was down to the Nant Cwy. This stream flows into Llangorse Lake so we were very hopeful to see some tiddlers (Baby fish)…We weren’t disappointed! Miss Jenkins helped us do a minute ‘kick sample’ – timed in seconds – to capture a wide range of different stream species. Our largest amount of animals found this time were mayfly nymphs. Look out for LOTS of mayflies this year! Ailsa, one of our school helpers, very kindly agreed to help us identify our catches.

Back to the classroom now to look at our findings and work out what it all means…

We’re really hoping we get to go to the beach so we can find out about rockpool animals too!
