All students collaboratively organize an event to showcase their work to an invited audience.
Students will work together across classes to create an event to showcase their scale model tiny homes and home system prototypes. Have the students plan the entire event from selecting a date/time and securing an event space to cleaning up after the event and closing out with the event space staff. To aid in collaboration it is recommended that students create a shared work board (Trello or similar) to create and assign tasks to student groups and/or individuals.
During the event each group should expect to have at least one person from their group dedicated to working for event coordination and hospitality. The remainder of the team is expected to represent the group project at their display "booth." If additional manpower is determined to be necessary you might take additional members from larger teams or have the students enlist volunteers from outside of the classroom. Every role at the event should be clearly defined in writing before the event. If any training is needed those materials should be created and distributed in advance of the event as well.
Showcase guests should be expected to participate at the event in some format. It could be as simple as voting with tokens for their favorite projects, perhaps even multiple colors for voting for a few different project components (best in show, best marketing, etc.). You may also decide to have a few judging panels of two or three special guests, such as builders, community guests, etc. that score student groups on a simple rubric. Hospitality is key, guests should feel that they are valued and invested in the process.
At the showcase, students groups should expect to be able to share a 30-second "elevator pitch" about their tiny home and to display their scale model and their energy system prototype. For the pitch they should prepare any supporting marketing materials (such as brochures, video, etc.) that they decide to develop.
