ThunderLaser STEAM Education Course (Thematic)
Having a music box is probably the dream of every child, whether it is a boy or a girl. When we were young, we dreamed that we could have a delicate music box, listen to the music flowing out of the music box, and put ourselves in the music world.
This special lesson will take music box as the theme. We all know that music can cultivate people’s sentiments, no matter adults or children. But music often has a bigger effect on children than it does on adults. According to researchers, music can develop children’s imagination, creativity, hearing, language and memory skills. Music learning promotes all kinds of activities. Not that listening to Beethoven will make you smarter, but that music has a very comprehensive promoting effect. Music is an art form, and when we combine art and science, an unexpected miracle or wonderful chemical reaction can occur. So what kind of amazing chemistry happens? We’ll have to go into the course and find out.
In this course, we still design the music box around the LaserMaker laser editing software, and cut out the design drawing with a tight and accurate laser machine, so as to mobilize the enthusiasm of students and let them assemble it. In the process of learning, we will not let the students operate according to the textbooks, but first guide them to think, in the production of music box before the first to do what preparatory work, such as design the shape of the music box, choose what music? And so on observation and thinking, that is, cultivate the child’s artistic sentiment but also exercise the child’s thinking ability, hands-on ability. Further enhance their comprehensive ability, so that they gradually become a group of creative small makers.
* Exercise students’ ability of observation, thinking and operation;
*Learn and use LaserMaker editing software to design;
*Learn and cut parts with a laser cutter;

1. Teaching introduction
Guide students into the topic of this lesson by asking questions:
1. What is a music box?
The earliest music boxes were called music boxes, also called octaves and self-songs.
It was a mechanical sounding instrument, and by turning a spring or crank, the box could make a crisp music sound.
2. What is the source of the music box?
They date back to medieval Europe during the Renaissance. At that time, in order to make the clock tower of the church, the mechanical device of the size of the clock was called “the group of bells that can make sound”.

1. How does the music box work?
The main part of the music box is composed of power source (spring or crank and other power source), sound cylinder, sound board, damping, bottom plate, transmission mechanism and other parts. The spring drives the drum to rotate, and the solder joint on the drum moves the edge of the chip thin strip, vibrates to make a sound, and turns down to form a movement.
The roller can be regarded as a musical score, and the maker will add solder spots to the roller according to the musical score.
The chip, on the other hand, can be seen as a piano key, which cuts thin strips (frequencies) of different lengths on the same piece of material. The more thin strips on the chip, the higher the number of notes, the richer the timbre and the better the tune.
2. In addition to making heart-shaped music boxes, what other shapes can you make music boxes?
3. Music box is too boring, what can you do to make your music box look more vivid?
