Introduction to Science

Science is a systematic and organized body of knowledge that explores the natural world.
It's based on observation, experimentation, and the development of testable explanations.
Scientific inquiry follows a cyclical process.
Identifying questions, proposing explanations (hypotheses), designing experiments, collecting data, analyzing results, drawing conclusions, and communicating findings.

Branches of Science

Science is broadly categorized into:
- Physical Sciences (study of non-living things): Physics, chemistry, and astronomy.
- Life Sciences (study of living organisms): Biology, zoology, botany, and ecology.
- Earth Sciences (study of the Earth): Geology, meteorology, and oceanography.

Scientific Method

The scientific method is a systematic approach used to answer scientific questions.
It involves several key steps:
- Observation: noticing a phenomenon.
- Questioning: forming a question about the observation.
- Hypothesis: proposing a possible explanation.
- Prediction: stating what you expect to happen if the hypothesis is true.
- Experimentation: testing the prediction under controlled conditions.
- Data Analysis: interpreting the experimental results.
- Conclusion: determining if the hypothesis is supported or not.
- Communicating results: sharing findings with others.

Characteristics of a Good Hypothesis

A hypothesis must be testable.
It should be based on previous observations and knowledge.
A good hypothesis makes a clear prediction, allowing for the design of an experiment to evaluate it.

Scientific Measurements

Accurate and precise measurements are crucial in science.
Scientists use standardized units and instruments for measurement.
Measurements are reported with appropriate significant figures to indicate the precision of the measurement.

Safety in Science Labs

Following safety protocols and procedures is essential during experiments.
Always wear appropriate personal protective equipment (PPE), like safety goggles, gloves, and aprons.
Be aware of the hazards of various chemicals and equipment.
Report any accidents or injuries to the teacher immediately.

Scientific Models

Models are simplified representations used to explain complex phenomena.
They can be physical, mathematical, or conceptual.
Models are valuable tools for understanding and predicting the outcome of events. Examples include atomic models or the model of the solar system.

Scientific Inquiry Skills

Observation: noticing and recording details of a phenomenon.
Classification: grouping similar objects or events.
Measurement: quantifying characteristics using standardized units.
Inference: explaining observations and drawing conclusions.
Prediction: forecasting future events based on past observations.
Data collection, analysis and interpretation of results

Critical Thinking

Critical thinking is the ability to analyze information objectively and form reasoned judgments.
Scientists must differentiate between fact, opinion, and bias.

Scientific Attitudes

Scientists should be skeptical, curious, and persistent in their investigations.
Integrity and honesty should be central to scientific work.
Scientists should be open to revising their ideas in the light of new information.
