Unit Map

Students are introduced to the concepts of engineering and technology. (30–40 min.)
The class reads a storybook in which twins Gayla and Natasha explore the field of Materials Engineering as they identify a material to replicate a petroglyph (rock carving). (90–120 min., 2–3 sessions.)
Students carry out investigations to compare the properties of two different materials. (60–90 min., 1–2 sessions.)
Students sort and test materials to identify which ones might be good choices for replicating an artifact. (120–150 min., 2–3 sessions.)
Students follow the steps of the Engineering Design Process to imagine, plan, create, test, and then improve their own petroglyph replicas. (140–170 min., 2–3 sessions)
