Unit Overview

Students use their understanding of the interactions of plants and insects to engineer a tool that can be used for pollination.

  • Grades 1–5 (Designed for grades 1–2; includes modifications for grades 3–5.)
  • Setting: In school
  • Science connection: Pollination, life cycles of plants
  • 5 lessons (8–9 class sessions)

Unit Map

Students are introduced to the concepts of engineering and technology. (30–40 min.)
The class reads a storybook in which a girl named Mariana living in the Dominican Republic explores the field of Agricultural Engineering to figure out why her ohelo plant won’t make berries. (90–120 min., 2–3 sessions)
Students learn about agricultural pest management. (40–50 min.)
Students conduct experiments to observe how well different materials pick up and deposit pollen from model flowers. (85–95 min., 2 sessions)
Students follow the steps of the Engineering Design Process to imagine, plan, create, test, and then improve their own hand pollinators. (110–120 min., 2 sessions)
