EiE - Now You're Cooking: Designing Solar Ovens - Lesson 2

Students think like green engineers as they analyze the life cycle of the paper they use in their classroom.

Reflection Questions

What strategies do you see Linda using to keep her young students engaged and curious about the lesson?

Linda has a very animated style of teaching that makes listening fun. She introduces challenging share-out strategies, modifies activities, and uses props to help keep her students engaged.

  • Rather than sharing their own thoughts after small group work, Linda has students share their peers’ ideas. (1:08)
  • At one point Linda brings a tree branch into the classroom to help students visualize where wood originally comes from. (1:58)
  • In the Life Cycle Assessment activity, Linda removed the step numbers from the handout pages and had her students reassemble the pages in order. This encouraged her students to reflect more deeply on each step in terms of content and sequence. (4:53)

How does studying of the life cycle of paper prepare students for the solar oven challenge?

Studying the process of paper production heightens awareness of environmental impacts. This helps students think about the low impact of a solar versus other cooking techniques, and broadens their understanding of the overall work of environmental engineers.

  • Calculating the amount of paper students in the school use raises awareness that, even though it is used one piece at a time, the overall impact of paper use (like cooking) is large. (4:00)
  • Steps in the process of making paper highlight environmental impacts like cutting trees, carrying them by truck, and putting them into the landfill. (5:51)
  • Linda’s trip to the recycling center reveals of the impact of the paper produced by their own school. (7:15)
