Introduction

This is the end of our science and engineering two-week project. After looking at others introducing their projects, I feel really impressed by how clever those designs are. The most impressive design was Jayden’s terrarium and Andrew’s roller. I have also learned a lot from my straw experiment.

Reflection

Even while everyone is aware that blowing through a straw can produce sound, real fascination arises when you realize that the mechanism of the straw’s mechanism can be used to build a thermoacoustic engine. Simple initiatives could also have a significant mechanism. I realized that instead of creating an overly complicated project, we should think about the time and resources that are still available.

Andrew’s roller is a good illustration. Elastic energy is converted into kinetic energy through his project. The rubber within the roller will tighten as you move it ahead. The roller is pushed in the opposite direction by the kinetic energy that results from the transformation of elastic energy into kinetic energy, returning the roller to your hands. In comparison to my design, this one only requires a plastic cup and a rubber band. I observed him finalize the design fairly early, giving himself plenty of time to solicit input. Each student in the science and engineering class was given an interview before being given the opportunity to sign the roller.

The project that stands out to me the most is Jayden’s terrarium. His design is the only one among the others that doesn’t need kinetic energy and is sustainable. His terrarium has been alive for 30 days since the project was finished, which is incredible. Throughout the course of the two weeks, I assisted him in building the terrarium, and I saw that he bought all the ingredients at the beginning of the second week, packaged them in a box, and even had leftovers. Because it was obvious how much work or resources he had left, he can stay on schedule thanks to this. He was acting very independently and effectively. A tweezer and a water bottle were among the materials he took into consideration. He created the light.

Conclusion

AlthoughI was unable to carry out my original intention to build a thermoacoustic engine, I was still able to understand its workings. My classmates have also taught me about their goals and crucial principles that are required for a lone project. As a result, I think this two-week project is quite worthwhile.
