Class 7 Science — Wastewater Story Important Questions with Answers (MCQ test)
Class 7 Science is the first full year photosynthesis, acids-bases and electric current share one textbook. The rationalized NCERT dropped a few older chapters; what remains is the set CBSE still samples in periodic tests. This hub writes one unique paragraph and a question cluster per surviving chapter so “nutrition in plants class 7 important questions” and “heat class 7 MCQ” resolve to real practice, not an empty subject shell. Answers stay behind a tap. Hindi and English stems sit together because most school papers are bilingual.
Sewage is more than dirty water — it is a public-health pipe. Grit, sedimentation, aeration and disinfection are the treatment words Class 7 wants. Open drains and uncovered manholes are not “normal city life”; they are infection routes. Household good practice (oil not down the sink) sits beside the plant diagram. Write the steps in order; shuffled steps lose the mark. You are on Wastewater Story (MCQ test), page 1 of 1 — 6 questions in this filter.
