The Class 8 Science Chapter 14 focuses on making you learn about the following sections:
In this Science Chapter 14 Class 8, the first section will focus on introducing the students to the fundamentals of electric current and how it works. The students will also learn why it is dangerous to touch any electrical appliance when they are touching the sockets with wet hands. The chapter also focuses on making the students learn how electricity passes through their body, what are the excellent conductors through which electricity can move quickly, why electricity doesn’t pass through the poor conductors, what stops electricity from passing through poor conductors, what are its mechanism, and many more.
The students will be explained everything about electricity in this chapter and what materials they can use to pass electricity whenever required and how they can that electricity is passing through that particular object. In Chapter 14 Class 8 Science subject, there will be many examples given in the NCERT book that explains how the objects conduct electricity and the objects that don’t conduct electricity.
The students will be getting a basic understanding of electricity and its properties when they are going through this chapter. There will be many questions asked in the examination on the conductors and insulators of electricity that the students will have to identify correctly.
Once the students have gone through the introduction section, there will be many questions that will remain unanswered. However, in this section, the students will understand the concept of liquids being a good conductor of electricity and what are the properties that make the liquid a good conductor of electricity.
When the students are reading this section, they will have to perform many tests to determine if liquids are a good conductor of electricity or not. They need to be careful when they are performing it practically to make sure that they are safe and secured. The students are required to perform many activities, as mentioned in the NCERT book. Most of the activities explain the laws of electricity, the basic understanding of how electricity passes through the circuit or conductors, and so on.
This chapter also focuses on making the students learn how the liquid is the best conductor of electricity and why they shouldn’t be testing it with bare hands. Also, they will learn about the heating effect when they are passing electricity through a filament of a bulb or through a copper wire that is connected through nails.
The students are also required to learn about strong and weak current in a given circuit by performing a few activities, as mentioned in the NCERT books. This will help them to learn about the magnetic effect, how to see the compass when the electricity is being passed through it, how two wires can light up a bulb, and many more things. It is an exciting subject to read and understand for every student if they are applying their logic and are willing to learn about the subject correctly.
In Class 8 Chapter 14 Science, students will also learn about the effects of the electric current. They will be asked in the examinations to list the results of the current. To answer these types of questions correctly, the students are required to learn about the chemical effects of electric current. This section will focus on making the students learn about the chemical effects, what are the effects produced when there is a current passed through any conducting solutions, and many more chemical equations.
The students are required to go through the activity sections carefully and understand everything that is mentioned in the activity’s column in the NCERT books. The students will learn about electrodes when they are going through the activity’s column. They can also perform all the experiments practically; however, they need to be careful so that they can protect themselves from getting a shock by the current that is passing through the objects.
The students will also learn about the life of William Nicholson, who was a British Chemist, and what he has done to determine the situations of electrodes when they are passing through the water. The study that he performed will make you learn how oxygen bubbles are formed when the electrodes are connected to the positive terminals of the battery. This section will also focus on making you learn how hydrogen bubbles are formed on the other electrode that is connected to the other end of the battery. The students will gain enough knowledge about it once they have gone through this section thoroughly.
Once the students have learnt about electrodes and its chemical effects, they will learn about electroplating in this section. There are many things for students to learn in this section. They will learn what happens when electricity is passed through the copper sulphate solution, how copper sulphate becomes disassociated from copper and sulphate, and the mechanism behind the phenomenon. Therefore, this section becomes essential for students to learn about electricity, the phenomenon of electroplating, and its chemical effects on a given equation. They will also learn about the uses of electroplating in the real world and where it is being applied.
Students will be asked various questions based on their learnings from this section. You can also learn about it by solving the questions given in the examples and activities in the NCERT book. Make sure that you go through this chapter now and then so that you don’t forget about the electroplating principles in the first place.
Once you have gone through the chapter thoroughly, you will be asked to resolve 12 questions in the given exercise. There will be numerous questions from all the above sections that you are going through while reading the chapter. You can solve the questions by applying your understanding that you would have got after reading the chapter. Make sure that you answer all the questions correctly so that you can get good marks in the examination. Also, before going through the questions, make sure that you read them carefully as most of the questions might be tricky for you.
