My niece's school did that too. It was unexpected but absolutely enjoyable. They had the older grades build fake companies around made up science-y products. The aim was to get people to "buy" the product by pitching it. To be honest, some of the products reminded me of some startups mentioned in HN. One kid even had a food delivery service with drones... My niece's grade go to build rovers and satellites. She built hers to something between voyager and sputnik. It even had "engines" that would light up (LEDs). Really fun event without the pressure of trying to look smart.
