Students could assess each other's interviewing skills using a class-developed observation tally sheet and videotaped interviews, via chat or email. The teacher could assess the content of the background information for exactness, supporting information and unbiased interpretations. As a whole group activity, students could develop a survey to be used for the community interviews and a method to store results electronically. The teacher could pair up students, and create an interview schedule for posting in the classroom. The teacher could facilitate a discussion on the interview process and evaluations.
Oxidation occurs in proportion to light, humidity, and pollutants.
They could investigate how oxidation affects the consistency and rate of change on an artifact and make inferences based on their observations of phenomena. In small groups, students could classify the artifacts they replicated and chart their classifications. An online chat with a scientist could help students understand the oxidation process. Teacher could evaluate each group's oxidation experiments using a checklist. The class could develop a scientific method checklist for use during their oxidation experiments.
