The P7s explored pond life with the help from OPAL Community Scientist and The Conservation Volunteers. They discovered that caddisfly and dragonfly larvae are found in healthy pond water. Snails and worm-like animals indicate that the pond water might be polluted. They also had the opportunity to discuss and create a pond life food chain. In addition the children were introduced to various types of lichens. Next week the children will use their knowledge of lichens to explore air quality.
