This is a web resource about changes in energy use over time that provides a student homework activity and a detailed teacher guide including questions for student discussion. The resource requires students to compare the electrical appliances currently used in their home with those used in the past. The activity encourages students to design a questionnaire for interviewing an older person about the appliances they used when growing up. A student worksheet provides activity instructions and a table listing appliances for recording their results, including alternatives to current technology used in the past.
