Learning objects Fair test: growing lettuce

TLF ID L1186

Run experiments in a plant research laboratory. Investigate the effects of different variables on the growth of lettuces. Research the answers to questions about how to achieve optimum hydroponic growth conditions. Examine the effect of key variables on growth: nitrogen, temperature, light intensity and light duration. This learning object is one in a series of three objects.
