Recently, our A Level Biology, IB Environmental Systems and Societies (ESS), and IB Biology pupils embarked on an exciting field trip to West Runton to investigate the fascinating ecology of local rock pools. This hands-on experience provided an excellent opportunity for pupils to deepen their understanding of marine biodiversity and ecological survey techniques.

The primary focus of the trip was to study the rich variety of life inhabiting the rock pools. Pupils began by identifying a diverse range of species observed during the excursion. Notable fauna included beadlet anemones, crabs, shrimp, gobies, sand eels, limpets, barnacles, among many others.

Following the animal identification, attention shifted to the marine flora, particularly the various species of seaweed present. Pupils carried out systematic sampling using transect lines placed at different heights up the shore. This method allowed them to examine whether the distribution of seaweed species correlated with their position relative to the tide line, offering insights into zonation patterns and environmental gradients within the rock pool ecosystem.

Back in the classroom, pupils analysed the collected data to identify trends and ecological relationships. They applied their findings by constructing kite diagrams, a visual tool that effectively represents species distribution and abundance along the transects. This exercise reinforced data interpretation skills and provided a meaningful connection between field observations and theoretical ecological concepts.
