I am a junior one student. I want to take part in the science and technology innovation competition. Are there any novel topics?

Good morning, teachers and classmates: I'm zy from Class 6, Grade 1. Today, the topic of my speech under the national flag is "Technology Moves My Heart". Human beings benefit from technology, and technology benefits from innovation. Last week, we ushered in the annual Science and Technology Festival. From Monday's science and technology competition to Thursday's visit, we deeply realized that the word "scientific invention" is not so far away, but really around us: maybe a small faucet is our inspiration, maybe a modified box is an invention that we will apply for a patent in the future, maybe a mirror, a clothes hanger ... Who knows, life is impermanent, maybe there will be future scientists among us ... we will be sent to the Science and Technology Festival. Not to mention new friends and new knowledge, the innovation ability we have gained alone is enough to make us take a step ahead of our classmates in other schools ... In terms of gadgets, we brainstorm and come up with all kinds of gadgets, which are not very practical, but after all, they are proof of our innovation! In the popular science knowledge contest, we may be right or wrong, but we dare to say and answer, which is the proof of our courage. In the trash can image design competition, our novel design won the praise of teachers, which is our bold proof ... There are also interesting "Eggs Hit the Earth" and the popular science debate contest in Grade Two ... These are all proof of our ability! Our gizmos may be rough ... our papers may be immature ... Compared with floating beds and nanotechnology, their existence may seem too small and naive ... but no one will deny them ... because today, they may become the next generation products of science and technology and fly into the homes of ordinary people! My speech is over, thank you! Lyx declined to reprint! Add 542 words to the answer (you didn't say a few words, add and subtract them yourself). Refuse to reprint!
