Lesson explores agricultural and engineering and challenges students to engineer a system out of everyday materials that can drop a seed every 15 cm over a 60 cm distance. Students learn about seed drills and planters and consider the impact these inventions have had on farming and agriculture over the years. Students build and test their planters, evaluate their designs and those of classmates, and share observations with their class.
8 – 18
- Learn about engineering design and redesign.
- Learn about machinery and systems for planting crops.
- Learn how engineering can help solve society’s challenges.
- Learn about teamwork and problem solving.
Anticipated Learner Outcomes
As a result of this activity, students should develop an understanding of:
- engineering design
- agricultural engineering
Students explore how engineers have solved societal problems such as increasing the effectiveness and efficiency of planting seeds. Students work in teams to devise a system using every day materials that can drop a sunflower or pumpkin seed every 15 cm over a 60 cm distance. They sketch their plans, build their system, test it, reflect on the challenge, and present to their class.
