Advice, Answer it yourself. Don't wait for another to speak up, take the initiative. We made a flower, the petals could spin. The person in our group who spoke up said "Because it was easy to assemble lol" Which I don't need to explain why that's bad and is a big regret of mine to have not answered it myself, I'm young I thought the older ones may have had more experience to answer something better. Do it yourself. The other group claimed they made a schoolbus, which honestly it didn't mattered it didn't look like one, their answer was much better "Teach kids about school buses and associate them with fun since they have a toy of one.". If you make a flower because its easy, say something like it teaches kids about nature and motivates them into (collecting)learning the different types of flowers in the collection of toy flowers you would release.
