Study Notes
Chapter 1: Introduction to Science and Technology
Science and Technology
- The study of science involves three major elements: attitudes, processes, and products.
- Science is a human endeavour that builds knowledge from systematic collection and analysis of evidence and rigorous reasoning.
- Science is used in various contexts, and its applications can benefit society, but also have limitations and potential abuses.
Values, Attitudes, and Ethics in Science
- Important values and attitudes in science include:
- Curiosity: desiring to explore and question the environment.
- Creativity: seeking innovative solutions to problems.
- Integrity: handling data and information with honesty.
- Objectivity: seeking data to validate observations without bias.
- Open-mindedness: accepting knowledge as tentative and being willing to change views.
- Tolerance for ambiguity: being comfortable with uncertainty.
- Resilience: persisting in the pursuit of answers despite setbacks.
- Responsibility: showing care for living things and the environment.
- Healthy scepticism: questioning observations and methods.
Science Process Skills
- Science process skills include:
- Observing and measuring accurately.
- Communicating effectively.
- Making inferences and developing hypotheses.
- Planning and designing experiments to test hypotheses.
Products of Science
- Products of science are the recorded information and ideas that have been developed through scientific inquiry.
- Examples of products of science include video conferencing, the Internet, and cloning.
Benefits and Limitations of Science and Technology
- Benefits of science and technology include:
- Improving health and prolonging lifespan.
- Making lives more comfortable and convenient.
- Enabling global communication.
- Reducing damage from natural disasters.
- Limitations of science and technology include:
- Polluting the environment.
- Destroying lives and depleting natural resources.
- Upsetting the balance of nature.
- Science cannot:
- Give life to non-living objects.
- Forecast future events.
- Explain religious matters.
Basic Laboratory Orientation
- Rules and regulations for laboratory safety include:
- Following teacher instructions.
- Keeping notebooks and papers away from equipment and chemicals.
- Reporting accidents and injuries immediately.
- Cleaning up spillages and washing hands after handling substances.
- Tying back long hair and wearing safety goggles.
- Hazard symbols and pictograms indicate physical, health, and environmental hazards.
- Laboratory apparatus should be drawn in outline and proportion, including:
- Thistle funnel.
- Retort stand.
- Filter funnel.
- Bell jar.
- Tripod stand.
- Beaker.
- Flat-bottomed flask.
- Test tube.
- Measuring cylinder.
- Conical flask.
- Water trough.
- Round-bottomed flask.
- Evaporating dish.
- Gas jar.
- Crucible.
Using the Bunsen Burner
- Steps to use the Bunsen burner safely include:
- Checking the rubber tubing connection.
- Ensuring the air hole is closed.
- Opening the gas tap.
- Igniting the lighter.
- Opening the air hole to obtain a non-luminous flame.
- Anatomy of a Bunsen burner includes:
- Barrel.
- Air hole.
- Jet.
- Types of flame:
- Non-luminous (blue) flame: occurs when the air hole is fully open.
- Luminous (orange) flame: occurs when the air hole is closed.
- Strike back occurs when there is too much air entering the air hole, causing the flame to burn at the jet instead of the top of the barrel.
