The Chemistry of Clean Water: Researching Water Quality in General Chemistry 1

A bronze sculpture displayed outdoors on a sunny day, featuring a row of human figures emerging from the top of a large weathered wooden block. The figures appear to be submerged from the chest down, with only their heads, faces, and raised arms visible above the surface. Each figure's arms are stretched upward with palms open, and some figures wear shackles or chains on their wrists, evoking themes of slavery, captivity, and the struggle for freedom. The faces of the figures convey anguish and resistance. The sculpture is set against a backdrop of lush green trees and a well-maintained grassy lawn, suggesting a memorial or museum setting.
