R15 Biology Trip to National Botanical Gardens of Wales
R15 enjoyed an interesting field trip to the National Botanical Gardens of Wales in Carmarthenshire. The aim of the Educational Visit was to collect data from natural sources of the pollution in the area. The pupils used natural indicators such as lichen and pond species to determine the air and water quality.
Pupils found many varied species in the ponds such as Bloodworms, Caddis Fly larvae and Efts (baby newts!). They also became experts on crusty, shrubby and leafy lichen as air pollution indicators. Much data was collected regarding the water quality in the Gardens. Pupils measured the temperature, dissolved solids, acidity, and oxygen availability of the water.
Following a very busy and productive day, pupils returned to Cardiff with enough data for many hours of analysis. Well done, R15.
