Your students have just entered grade 8. If students have largely mastered the concepts taught till grade 7 as per NCERT, which of the following will they most likely NOT be able to describe?

Option 4 : Adoption of protective measures during earthquakes 

In the curriculum concepts are arranged in a certain order according to the understanding capacity and the developing cognitive abilities of the students. The concepts become more deeper when they progress from one grade to the other. 

• Children have got familiar with the relationship between formation of winds and air pressure because it is included in the grade 7 curriculum and before also and also is clear and precise.
• Expansion of air as a result of heating is also clearly discussed in grade 7 with the appropriate examples so that students can understand clearly.
• Adoption of safety measures during cyclones will also be mastered by the students because this topic is also discussed in the curriculum of grade 7 clearly along with pictures regarding the topic.
• Children can't clearly describe the adoption of protective measures during earthquakes because more detailed information about this topic is discussed in upper grades from 7 than in 7 itself.

Hence children can't clearly describe the adoption of protective measures during earthquakes
