One of our environmental-themed activities for Grade 7 students in First Nation communities this year is called Battle of the Wraps.
Students boiled water and poured it into several paper cups, then wrapped the cups with different materials to test their insulating properties. They measured the temperature of each cup every 3 minutes and compared bubble wrap, aluminum foil, cotton fabric, and newspaper, while leaving one cup uncovered as a control.
Through this hands-on experiment, students learned why insulation is used in homes, jackets, and coolers. Insulation helps conserve energy, maintain comfortable temperatures, and reduce heating costs. The activity also gave students valuable practice in recording, analyzing, and graphing data.
We thank Carly Keshen for leading this engaging and educational activity. Carly is an MSC student in Medical Sciences at UofT, working on a project to improve the understanding of women's health.
