Field trip: studying an aquatic ecosystem. Casa de Campo lake.

Our 3rd-year Secondary students went on a field trip to the Casa de Campo park to carry out an interesting activity introducing them to fieldwork and the scientific method.

We began with a short introductory talk about the activity at the Nature Classroom, followed by a lovely 2 km walk to the Casa de Campo lake. There, the students took measurements of pH, temperature and light penetration in the water, and collected samples with water nets.

Back at the Nature Classroom, they carried out lab work, observing the living organisms present in the lake under microscopes and using identification keys to classify them.

It was an unforgettable day in the field ?
