The document describes an experiment measuring the evaporation of water from containers with different surface areas. It found that containers with greater surface areas evaporated more water, with evaporation amounts of 4, 8, 16, and 32 ml from containers with surface areas of 25, 49, 100, and 196 cm^2 respectively. It concludes that surface area affects evaporation, with larger surface areas leading to greater evaporation over time.
