My niece&#x27;s school did that too. It was <i>unexpected</i> but absolutely enjoyable. They had the older grades build fake companies around made up science-y products. The aim was to get people to &quot;buy&quot; 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&#x27;s grade go to build rovers and satellites. She built hers to something between voyager and sputnik. It even had &quot;engines&quot; that would light up (LEDs). Really fun event without the pressure of trying to look smart.
