Teaching Process:

Classroom Discipline and Rules Emphasis

Teacher: Good morning, children.~Today is another exciting science experiment class. Guess what we're going to do today?

Create robots! Conduct chemical experiments!

Teacher: You all guessed what we will cover in science class later. Today, we are going to do an interesting innovative experiment.

Teacher: However, before class starts, the teacher would like to remind you of the safety precautions for the experiment.

Firstly, before the experiment class, you should carefully review the material, understand the purpose, principles, experimental steps, and precautions of the experiment.

You must also follow the teacher's arrangements and not take any actions on your own.

Secondly, we must wear clean clothes when entering the laboratory; it is not allowed to enter the laboratory with slippers or vests. Without the permission of the teacher, no food is allowed in the laboratory. Students cannot make noise or violate discipline in class; they cannot fall asleep during class. They should be willing to cooperate with classmates to maintain the cleanliness of the desk, and they should complete the experimental operations on time.

Thirdly, in the experiment, you must follow the teacher's guidance, operate carefully, observe carefully, record the experimental data and results honestly, actively analyze and think about the test results, and do not copy each other's experimental data. These are the requirements for you in this science class. Can you do it?

Yes, I can!

Teacher: It seems like you don't have much confidence! Tell me loudly, can you do it?

Life: Can (loudly)

The experiment with the double-headed street lamp utilizes the principle of parallel circuits. When we connect two street lamps with wires, switches, and a battery to form a parallel circuit, when we press the switch, the electrical energy from the battery can be transmitted to the light bulbs, thus enabling the double-headed street lamp to achieve the effect of illumination. Parallel connection is a type of connection between components, which features that two or more similar or different components, devices, etc., are connected at the beginning and end, simultaneously. It is usually used to refer to the connection method of electronic components in circuits, that is, parallel circuits.
