Competency practice: A classmate can recall the heading Measurement of Time and Motion but cannot explain it. How will you teach it in two steps using the textbook idea?
Answer
Step 1: State the fact — A simple pendulum was used historically for time. Step 2: Show one example or diagram from the chapter and ask the classmate to repeat it in their own words.
Explanation
Competency-based items check whether you can use a concept, not only name it. Teach-back is a simple way to prove understanding.
Meta
Class: Class 7 · Subject: Science · Chapter: Measurement of Time and Motion · Original GKSchools practice (NCERT-aligned, not an official CBSE paper).
FAQs
Are these official CBSE board questions?
No. They are original practice questions aligned to NCERT topics used in CBSE classrooms. Official sample papers are published on cbseacademic.nic.in.
Will these questions appear in the board exam?
Nobody can promise a question. Use them for revision of frequently tested concepts and exam-style practice.
Is the chapter list the latest NCERT list?
Yes, the catalog follows current NCERT textbooks used in CBSE schools (including new middle-stage books such as Ganita Prakash and Curiosity). Always match the book issued by your school.
Where are NCERT solutions?
Open the NCERT-style practice link on this subject or chapter. For word-for-word textbook exercise answers, use the NCERT book itself; we do not copy solution keys from other websites.
What is the suggested URL pattern?
Hub /cbse/, then /cbse/class-7/, then subject and chapter slugs.
Why is this a separate URL?
So students searching for “Competency Based Questions” land on a filtered set, while the chapter page remains the full 100-question bank. Same facts, different search intent.
