NCERT Class 8 Science Chapter 15 Topic-Wise Discussion

The chapter of some natural phenomena Class 8 has seven sections. Here is a brief idea about each of them –

1. Lightning

After a generic introduction, the Ch 15 Science Class 8 begins with a discussion about lightning. It describes what lightning is and how it is perceived in recent times compared to ancient times. It further encourages students to perform a home-made experience to learn how electric charge is associated with lightning.

2. Charging by Rubbing

This sub-topic in Class 8 Science Chapter 15 talks about how electric charge is produced by rubbing two objects together. It uses an activity to urge students to understand this natural phenomenon. With the help of this activity, they can experience it first-hand and comprehend the topic better.

3. Types of Charges and their Interaction

This topic takes the discussion on charges a step further. In this sub-topic of NCERT Solutions Class 8 Science Chapter 15, students will learn how two similar charges are not attracted to each other. There are two activities that candidates can perform at their home to understand this concept better. In one experiment, students can use two inflated balloons and rub them with a woollen cloth. Once finished, they will observe that both of them are not coming together.

4. Transfer of Charge

This section in NCERT solution Class 8 Science Chapter 15 shows how metal can transfer charge. In the activity mentioned here, students can use a paperclip, empty refill of a ball pen, and two strips of aluminium foil to learn more about this concept. Also, they get to know about electroscopes, a device used to check whether an object is carrying charge or not.

5. Story of Lightning

NCERT solutions for Class 8 Science Chapter 15 Some Natural Phenomena further talks about the concept of lightning and the story behind it. Even though not fully discovered, researches have shown how positive and negative charges present in clouds cause this phenomenon. Before a thunderstorm, the air currents move upwards, and the water droplets move downward. It separates the currents. When the accumulation of these charges becomes high, it causes the lightning or electric discharge.

6. Lightning Safety

In this section of NCERT Solutions for Class 8 Science Chapter Some Natural Phenomena students learn about the necessary safety measures during thunderstorms and lightning. It includes the places that are safe during such situations, and the do’s and does not. This section further discusses light conductors and their importance in protecting buildings.

7. Earthquake

The last sub-topic in these NCERT solutions for Class 8 Science Ch 15 includes a detailed discussion about earthquakes. It is a complicated and highly unpredictable natural phenomenon. However, with the help of modern equipment, earthquakes can be predicted to a certain extent. This sub-topic then explains the definition and causes of an earthquake and how one can stay safe during this natural phenomenon.
