Repeat this process for Cup D and record your results in the chart. Students will demonstrate the ability to work scientifically and accurately in the lab. Students will answer questions as to why the water looked dome-like and took so long to overflow. Students will make a hypothesis as to why and how the different conditions in the water affected the surface tension. Students should analyze error in technique that may have affected the results.
Students explore the possibilities of surface tension.
They will see how detergent and heat lower surface tension. Higher level students may explore bonds and polarity affecting surface tension. Hands on General Science Activities with Real-Life Application . The Center for Applied Research in Education.
