Haryana BSEH Secondary Science study guide
Haryana BSEH Secondary Science · Work through your exam, one topic at a time.
The Haryana Board of School Education (BSEH), usually called HBSE, conducts the Secondary examination that ends Class 10 for students in Haryana's affiliated schools. The Science paper is a single subject examination combining physics, chemistry, biology and environmental science, and it is a qualifying subject for promotion to Class 11 as well as for many state-level certificate and diploma admissions. The Haryana BSEH Secondary Science study guide has 8 sections and about 2,559 words.
01Chemical Substances and Processes
This domain examines how substances react, how we classify them, and how their properties explain everyday behaviour. BSEH questions usually ask you to balance equations, identify reaction types, use the pH scale, apply the reactivity series, and recognise functional groups in carbon compounds.
323 words, about 2 min02World of Living
This domain covers the processes that keep organisms alive, how plants and animals coordinate responses, how organisms reproduce, and how traits pass from parents to offspring. BSEH questions often require you to compare processes, interpret a Punnett square, and explain a hormone or a reflex pathway.
301 words, about 2 min03Natural Phenomena
Natural phenomena in this exam focuses on light: reflection at mirrors, refraction through lenses and glass, the human eye, and optical defects. Questions test the laws, ray diagrams, the mirror and lens formulae, power of a lens, and everyday effects such as dispersion and scattering.
354 words, about 2 min04Effects of Current
This domain tests electric current, potential difference, resistance, household circuits, the heating effect, and the magnetic effect of current. Expect numerical problems, circuit reasoning, and questions on motors, generators and safety devices.
346 words, about 2 min05Natural Resources and Environment
Natural resources and environment questions ask how ecosystems move energy and matter, how human activity affects air, water, soil and biodiversity, and how resources can be managed sustainably. The exam favours food chains, the 10% law, pollution, ozone depletion and conservation measures.
304 words, about 2 min06Practical and Experimental Skills
Practical and experimental skills questions test whether you can choose apparatus, take reliable readings, control variables, record units and interpret results. They often use familiar Class 10 experiments such as pH testing, resistance measurement and the refraction of light.
303 words, about 2 min07Scientific Literacy and Application
Scientific literacy and application tests whether you can use evidence, interpret data and apply science to everyday decisions. Questions may give a short claim, a table or a graph and ask you to identify variables, judge reliability, or explain a technological choice.
304 words, about 2 min08Health, Nutrition and Hygiene
This domain covers nutrients, a balanced diet, deficiency diseases, personal and community hygiene, communicable disease prevention, first aid and adolescent health. Questions often ask you to match a deficiency with its symptom or choose a safe public-health action.
