Why Is The Water Green? (Lab Investigation)

NEO20

Investigate how common pollutants affect microlife. Lab Kit for 40 students. Investigate how common pollutants--detergents and fertilizers--affect the growth of microalgae in ponds, contributing to environmental problems. Using either the unique dried culture mix included, or pond water samples they collect themselves, students explore how algae are affected by phosphates and nitrates and the concentration at which these common pollutants cause algal blooms. Further investigations allow students to determine the effects of other common pollutants on living organisms and the environment.
