How to fix the circuit components in place - part 4
If you screw the bolts too far into the motor, it may stop working. This won’t be an issue later, but if it causes problems now, place a few nuts on the bolt before using it. This will stop the bolt from going too deep into the motor.

Connecting the simple circuit - part 1
It doesn’t matter if you connect the wire to the positive (cathode) or the negative (anode) terminal of the battery.
Note that for power sources, the cathode and anode are marked opposite to that of diodes and other electronics. In them, the cathode is the positive terminal and the anode is the negative one.

Teacher's Notes: Music Box
Due to the long construction, you need to be careful with time in this lesson. Don’t let the students spend too much time building. If you think you can manage it, you may let them find their own sheet music and adapt it, but we recommend sticking to the short section from Ode to Joy as shown in the tutorial. This melody also serves as preparation for the next lesson, where a ready melody will again be needed. Here’s what the program looks like:
