The document summarizes an experiment comparing the temperature change of salt water and fresh water over 5 minutes. It found that on average, salt water increased in temperature by 46.85 degrees compared to 45.35 degrees for fresh water, supporting the hypothesis that salt water would increase in temperature more than fresh water over the time period. Key observations for salt water included steam forming and salt moving around, while fresh water showed bubble formation. The conclusion confirmed that salt water's temperature increased more than fresh water at the 5 minute mark.
