Hydroponics cultivation is an innovative educational and learning tool suitable for pupils of all ages. The laboratory trial consists in the hydroponic cultivation of basil plants by using recycled mineral water plastic bottles. A dosage of struvite (10 and 100 mg/L) is supplied at the basil plants, in order to evaluate the efficiency of struvite. After a period of cultivation, about 3 weeks, the plants are removed by the hydroponic system and the fresh and dray weights of each treated plants are measured. This laboratory experience will develop a variety of interdisciplinary and practical skills in the disciplines of plant biology, ecology and sustainability, chemistry, nutrition, water, alternative energy, technology and mathematics.
