Important Points to Remember – Class 8 Science
- Science investigation begins with focused questions and designing simple experiments to observe, experiment thoughtfully, and explain clearly based on observations.
- The human eye can only see objects above a certain size; microscopes help us explore the invisible living world of tiny organisms beyond our naked eye.
- A lens is shaped like a lentil seed (thick in middle, thin at edges) and was the foundation for developing magnifying glasses and microscopes.
- Health is more than just absence of disease – it includes feeling good physically, maintaining positive mindset, and having strong social relationships.
- Current health challenges in India include 11.4% diabetic population, 28.6% obesity rate, and air pollution as a leading health risk factor.
- Electric current produces magnetic effects – an iron nail wrapped with wire and connected to battery becomes an electromagnet when circuit is closed.
- Temporary magnets can be created using electromagnets by passing electric current through a coil wrapped around magnetic material like iron.
- Magnetic compass is used to detect magnetic effects of electric current in simple circuit experiments.
- Regular handwashing reduces infection by 50% and safe drinking water reduces water-borne and vector-borne diseases significantly.
- Electric circuits can be tested for current flow using magnetic compass instead of electric lamp by observing needle deflection.
- Yoga reduces anxiety, increases concentration and promotes overall mind, body and soul wellness according to health studies.
- Climate change can potentially lead to new types of diseases and affect different population groups during disease outbreaks.
- Fast food consumption is identified as one of the leading causes of diabetes in the Indian population.
- Excessive screen time in children leads to rise in obesity, sleep disorders, anxiety and dry eye disease.
- The CBSE 2024-25 curriculum emphasizes investigative approach to science learning rather than just memorizing facts.
Quick Revision Notes – Class 8 Science
- Focus on Activity 2.1 using round-bottom glass flask for observation – this demonstrates how lenses work and is frequently asked in practicals.
- Remember the connection between microscope invention and discovery of microorganisms – timeline questions are common in board exams.
- Health definition has evolved from "absence of disease" to complete physical, mental and social well-being – 3-mark question pattern.
- Activity 4.1 electromagnet experiment requires magnetic compass, electric cell, connecting wires, drawing pins, safety pin and cardboard pieces.
- Diagram of electromagnet working model with iron nail, wire coil and battery connection is important for 5-mark questions.
- Statistics to memorize: 11.4% diabetes, 28.6% obesity, 50% infection reduction through handwashing – numerical data questions expected.
- "Probe and Ponder" questions at chapter beginning help develop investigative thinking – practice answering these for long answers.
- Lens terminology: thick in middle, thin at edges, named after lentil seed shape – definition questions worth 2 marks each.
- Health factors interconnection: stress/emotions affecting physical health, social determinants of health – analytical questions for 5 marks.
- Electric current magnetic effect demonstration: circuit completion attracts iron clips, circuit breaking releases them – cause-effect relationships.
- Climate change and disease emergence topic connects environmental science with health – interdisciplinary questions trending in recent papers.
- FIT INDIA movement recommendations: reduce oil by 10%, reduce sugar intake, regular yoga practice – policy-based questions possible.
- Vector-borne diseases increase during monsoon season – seasonal disease patterns and prevention measures for 3-mark questions.
- Temporary vs permanent magnets distinction through electromagnet examples – comparison questions worth 4-5 marks in board exams.
- Investigation process: wonder → focused questions → simple experiments → observations → improved understanding – process-based questions expected.
