  • Fair test tip: change only one variable at a time and repeat trials.
  • Common tools and units: thermometer, balance, magnifier; length in cm, mass in g, temperature in °C.
  • Safety rules: wear apron, tie hair, avoid tasting materials, handle glass and hot items carefully.

Questions students ask

What is a hypothesis and how to make one?

A hypothesis is a simple, testable guess that explains an observation. Make it specific, predict an outcome and design a small experiment that changes only one variable so results clearly support or reject the hypothesis.

How to write good observations for practicals?

Write only what you see or measure using neat tables and labelled drawings; always include units and exact measurements. Also note time, avoid opinions, repeat trials if needed, and mention any unexpected results.

Difference between living and non-living things?

Living things grow, move, respire, need food and reproduce; non-living things do not show these life processes. In answers give class examples and observations such as growth, movement or response to stimuli as evidence.

How to answer experiment and observation questions in exams?

Begin with a clear aim and list of materials, give a short numbered procedure, record observations with units and labelled diagrams, then end with a concise conclusion and any simple inference.
