Presentation and communication

Building a good prototype and not knowing how to explain it leaves the project half finished. Communicating well what you have done is as much a part of technical work as the workshop itself.

Before you start, make sure you know: The phases of the technology project (1st ESO)
Before you start, make sure you know: Documents, spreadsheets and presentations (2nd ESO)

Preparing the presentation: structure and content

A technical presentation always follows the same logical order, so that the audience understands the problem before seeing the solution.

Four scenes showing the order of a technical presentation: grabbing attention with an object and a question, explaining the problem on screen, showing the prototype and finishing with conclusions and improvements. ? grab attention ! explain the problem show the solution conclusions lessons learned and improvements

Slides, display boards and posters

Each format is "read" in a different way, and that changes how much text and what size of lettering it needs.

Comparison of three communication formats: a slide with little text in large lettering, a display board with a short phrase and an image, and a poster with several blocks of information. large text slide a few seconds, live one phrase display board in passing, from afar block 1 block 2 poster up close, at leisure

Speaking in public

Well-prepared content can be ruined by a poor delivery, and the other way round: rehearsing improves the result a great deal.

A speaker standing with an open posture talks in a clear voice (sound waves), looks at the listeners seated in front, pauses to set the pace of the talk and has rehearsed beforehand, next to a screen showing slides. loud voice and clear look at the audience pauses and pace rehearse beforehand

Your team has designed a waste sorter with a colour sensor and a servomotor for the workshop, but the final cost (42,50 €) exceeded the budget limit of 30,00 € and the detection reliability is 82 % under variable ambient light. Design the script for an elevator pitch presentation of exactly 2 minutes before the school management team to convince them to fund an improved version. Structure the time in second blocks, write the impactful opening, explain how you will justify the extra cost and technical margin of error without losing credibility, and formulate a clear call to action.

During the defence of an automated Arduino greenhouse, the panel raises two critical objections: 1) 'If the power supply or Wi-Fi network fails, the plants die in a matter of hours because you have not provided manual redundancy or an acoustic alert'; 2) 'You claim the system saves 35,5 % of water, but you have only recorded measurements over 3 winter days'. Design the technical response strategy for both objections: acknowledge the prototype's limitations with technical honesty, justify what design constraints led to those decisions, and propose the specific hardware and testing improvements you would implement in a second phase.
