Participants will use sensemaking and the engineering design process to solve a real world food production problem in a small scale format. This lesson introduces the Food Delivery Challenge, in which participants must design a gravity feeder
to carry food (chicken feed) to twelve hungry chickens for over 24 hours. To accomplish the task students must design and build a model of an efficient gravity feeder using the materials available to them. The scenario presented to the class: One of the feeders in your uncle’s barn has broken down, and a new one will not arrive until next month. You must create a gravity feeder to satisfy 12 chickens for 24 hours consistently to ensure the health of your flock.
Participants will research, design, build and test their design before presenting to the group for feedback, Participants will then use the feedback to redesign for an improved feeder.
1. Use the engineering design process to collaborate, design and build a gravitational feeder system that will feed 10 pounds of feed over a 24 hour period.
2. Present your design plan, and final product to the class for feedback.
3. Provide feedback to the design team for design improvement.
