1. The small bulb lights up the lesson plan:

In life, batteries are often used in series. Connect the negative terminal of one battery to the positive terminal of another, and the remaining positive and negative terminals will be the positive and negative terminals of the battery group. This way, you can connect two, three, or more batteries in series.
A circuit composed of electrical devices connected one after another with wires is known as a series circuit.
The Law of Voltage in Series Bulbs
The characteristics of a series circuit
The switch controls the entire circuit regardless of its position, meaning its function is independent of its location. Current flows through only one path, and the current passing through one lamp must also pass through the other. If one lamp is turned off, the other will also turn off.

Scientific Principles:
In a series circuit, the current through each resistor is equal, and the sum of the voltages across each resistor is equal to the total circuit voltage. It can be known that the voltage across each resistor is less than the total circuit voltage, so the series resistors share the voltage.
In a parallel circuit, the voltage across each resistor is equal, and the sum of the currents in each resistor is equal to the total current (dry circuit current). It can be known that the current in each resistor is less than the total current (dry circuit current), so the parallel resistance is divided. The series and parallel of resistors is like water flow, in series there is only one path, the larger the resistance, the slower the flow, the more the branches of the parallel, the larger the current.
Battery series connection
In life, batteries are often used in series. Connect the negative terminal of one battery to the positive terminal of another, and the remaining positive and negative terminals will be the positive and negative terminals of the battery group. This way, you can connect two, three, or more batteries in series.
Scientific Inquiry:
In our daily life, we often see electric lights in our homes and classrooms that can light up when the power is turned on. How do they work? Where does the electricity come from? Let's explore the reasons behind the bulb's light and how the circuit is connected through experiments.

Electromagnetic Induction Course

Experimental Focus: Every day on campus, students hear the school bell ringing for classes and recess. How can an electric bell make a sound without being struck by hand? Some students may know it's because of an electromagnet, but how does an electromagnet make the electric bell produce sound? Let's understand the working principle of an electromagnet through the experiment below.

Experimental Purpose:

1. Learn to make an electromagnet with a nail
2. Understanding the structure of electromagnets and their applications in daily life

Experimental Cognition: A device that produces electromagnetic force when electric current flows through it. By winding a conductive coil around the iron core, which matches its power, the coil, like a magnet, becomes magnetic. It is also known as an electromagnetic iron. We usually make it into a bar or hoof shape to make the iron core easier to magnetize. The electromagnetic iron is an application of the magnetic effect of electric current, which is closely related to life; the electromagnetic iron is a device that can produce magnetic force by passing current, which is not a permanent magnet and can easily start or eliminate its magnetism. The working principle of the electromagnetic iron: In simple terms, it is the magnetic effect of electric current. When the coil is powered, the iron core inside is magnetized by the magnetic field of the electric wire. After magnetization, the iron core becomes a magnet, so that the magnetic force of the wire is greatly enhanced due to the superimposition of the two magnetic fields. The iron core and the core of the electromagnetic iron are magnetized to become two pieces of magnets with opposite magnetic polarity, and they generate electromagnetic attraction between them. The electromagnetic iron uses the electromagnetic force generated by the current-carrying iron core to manipulate mechanical devices to complete the expected action.

Knowledge Expansion: The direction of the magnetic field of an electromagnet can be determined using Ampère's right-hand rule. Ampère's right-hand rule is a rule that indicates the relationship between the direction of the current and the direction of the magnetic flux lines generated by the current. It is also known as the right-hand spiral rule. 1. Ampère's right-hand rule for a straight electric conductors (Ampère's right-hand rule I): Use your right hand to hold the straight electric conductor, with your thumb pointing to the direction of the current, and your fingers pointing to the direction of the magnetic flux around the conductor. 2. Ampère's right-hand rule for a solenoid (Ampère's right-hand rule II): Use your right hand to hold the solenoid, with your fingers bent to match the direction of the current, and your thumb pointing to the N pole of the solenoid. Electromagnets have many advantages: The presence or absence of magnetism can be controlled by turning on or breaking the current; the strength of magnetism can be controlled by the strength of the current or the number of turns in the coil; the magnetic polarity can also be controlled by changing the resistance to control the size of the current; and the direction of the magnetic pole can be controlled by changing the direction of the current, and so on. That is to say: The strength of magnetism can be changed, the presence or absence of magnetism can be controlled, the direction of the magnetic pole can be changed, and magnetism can disappear when the current disappears.

  Before assembling, please check if the circuit is unblocked and all the components are complete. Ensure that all contact points are in good contact. During the assembly process, be careful not to get glue on your clothes or skin. Keep the parts out of reach of younger siblings to prevent them from swallowing them by mistake! Do not play with them on your head, to avoid the model falling and injuring you!
