Science

Science is a body of knowledge which involves investigations and experimentation. It involves observation, experimentation, or investigation of various phenomena.

Meaning of Science

Science is a Body of Knowledge

Science is a collection of facts, principles, and explanations gathered through investigations and research. It helps us understand the world around us.

• Example: The knowledge that the Earth rotates around the Sun is part of science.

Science Involves Investigations and Experimentation

Science requires research, experiments, and investigations to discover new things and confirm existing knowledge.

Investigation: Studying something carefully to understand it better.

Example: A scientist investigating how different types of soil affect plant growth.

Experimentation: Testing ideas to prove whether they are true or not.

Example: Mixing different liquids in a lab to see how they react.

Science Involves Observation, Experimentation, or Investigation of Various Phenomena

Science helps to study and explain phenomena (natural events) by using observation, experimentation, and investigation.

Observation: Watching something carefully using the senses or tools.

Example: Observing how the sun rises and sets every day.

Experimentation: Performing tests to confirm ideas.

Example: Testing whether hot water freezes faster than cold water.

Investigation: Researching and collecting information to find answers.

Example: Investigating why volcanoes erupt.

Experiments Can Involve Measurement of Various Parameters Such As Temperature, Length, and Mass

Science involves measuring different things to understand them better.

Temperature: Measures how hot or cold something is.

Example: Using a thermometer to check if a patient has a fever.

Length: Measures how long something is.

Example: Measuring the height of a person using a ruler.

Mass: Measures how heavy something is.

Example: Weighing a bag of flour using a scale.

Science is Used to Explain How Things Work in the Real World

Science helps us understand how things happen in nature.

Rain Formation: Science explains how water evaporates, forms clouds, and falls back as rain.

Occurrence of Earthquakes: Scientists study how movements in the Earth's crust cause earthquakes.

Thunderstorms: Science explains how lightning and thunder form due to the movement of warm and cold air.

Science Helps to Make Tools and Machines That Are Used to Simplify Work or Solve Problems in Our Daily Life

Science is used to create machines, tools, and technology that make life easier.

Using scientific tools

Transportation: Science helps in making cars, airplanes, and bicycles.

Technology: Science is used to create mobile phones, televisions, and computers.

Medicine: Science helps in making medicines, vaccines, and medical equipment.

A Person Who Does Scientific Work is Called a Scientist

A scientist is someone who studies science, conducts experiments, and makes discoveries.

Scientists work in different fields like biology, chemistry, and physics.

Example: Isaac Newton discovered gravity, and Marie Curie studied radioactivity.
