Planting with Precision

In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting. Learners work in teams to devise a system using everyday materials that can drop a sunflower or pumpkin seed every 15 cm over a 60 cm distance. Teams sketch their plans, build their system, test it, reflect on the challenge, and present their experiences to the group.
