this are all the topics i have to read and understand
1. Measurements & Units
Scalar and vector quantities
Volume, area, and density calculations
Measurement errors and precautions
Conversion between units (mm, cm, km)
2. Living Matter (Plants and Animals)
Classification of living organisms (vertebrates, invertebrates)
Plant and animal cell structures
Energy flow in living things (photosynthesis, respiration, transpiration)
Food chains and food webs
3. Acids, Bases, and pH
Properties of acids and bases
Use of indicators (litmus paper, universal indicators)
Neutralization and safety with acids and alkalis
Testing substances for pH
4. Forces, Motion, and Energy
Energy forms and changes (kinetic, potential, mechanical energy)
Calculation of forces and moments
Energy transformations (power stations, photosynthesis, respiration)
Renewable and non-renewable energy sources
5. Electricity and Magnetism
Electrical circuits (series vs parallel)
Voltage, current, and resistance calculations (Ohm’s law)
Uses of fuses, wires, and safety precautions in electrical appliances
Magnetization methods and magnetic materials
6. Health and Safety
Reproductive health (puberty, menstrual cycle, fertilization)
Communicable and non-communicable diseases
First aid procedures (for poison, burns)
Personal and environmental health (hygiene, disease prevention)
7. Water and States of Matter
Properties of matter (solids, liquids, gases)
Water as a universal solvent and anomalous expansion
States of matter transitions (melting, boiling, freezing)
Conservation of water resources and environmental impact
8. The Human Body
Circulatory system (heart, blood vessels)
Digestive system (processes and enzymes)
Reproductive system (hormones, fertilization)
Respiratory system (lungs, gaseous exchange)
9. Sound and Light Energy
Sound wave properties (pitch, frequency)
Reflection, refraction, and absorption of light
Uses of mirrors and lenses in optics
Speed of sound in different mediums
