Big Ideas Of Science
Average Learning Time
This inquiry activity teaches students about the chemistry of household chemicals. It allows them to conduct experiments and gather evidence using the online laboratories Acid-Base Solutions and pH Scale: Basics Lab. Students work through an inquiry cycle model and acquire scientific investigative skills. They investigate three research questions: (1) What does pH measure? (2) What type of chemical solution can cause a chemical burn? (3) How does adding water to a chemical solution change its pH level?
This inquiry activity is based on the Structure Controversy scenario and includes a Debate phase. Students debate the question: Should dangerous household chemicals be banned? Students in this ILS are assigned to argue the NO position.
