One area of study in aquatic ecology is microbiology. Microorganisms living in and around water systems are foundational and interesting. One of the ways to see evidence of this life is by studying biofilms, substances created by the microbes to live in colonies and communities. Winogradsky columns are a simple experiment to grow your own microorganism communities from local creeks in the Central Highlands.
