South 고등학교 1학년 Science Inquiry Experiments 2
Chapters: 2
1. Inquiry in everyday life
Science in film, food, sport, media · Finding inquiry questions · Designing solutions
- Science in Daily Life – Science is not only in labs. Cooking uses chemical changes. Soap cleans because one end of its particle likes water and the other likes oil. Acids and bases react, for example vinegar and baking soda give carbon dioxide. Sport is full of forces and motion. Films, adverts and social media use science too, so we must check claims for evidence.
- The Scientific Method – The scientific method is the careful way scientists find out how the world works. Observe something, ask a testable question, make a hypothesis (a clear, testable guess), test it with a fair experiment (change one variable, measure one, keep the rest the same), repeat and record data, analyse it, draw a conclusion and share it so others can check. Results that fail the test are useful too: they send you back to a new hypothesis.
- The Design Process: From Problem to Product – The design process is a loop of steps designers use to solve a real problem for real people: investigate the need, define it in a brief and a measurable specification, generate many ideas, build a prototype, then test and evaluate it against the specification. Whatever fails sends you back round the loop. This repeating is called iteration, and it is how almost every product, app, building and artwork is improved.
2. Future society and advanced science
Science inside advanced technology · Sharing inquiry products · Research ethics
- Science Inside Advanced Technology – Advanced technology is ordinary science used in clever ways. Sensors turn touch, light and motion into electric signals. Chips are made of silicon. New materials such as graphene get their power from how atoms are arranged. New medicines are designed to fit a target like a key fits a lock. When biology, information and nano-science meet, new fields appear.
- Science Communication: Sharing and Judging Scientific Results – Science communication means sharing findings clearly and honestly, and judging what others claim. Fit the message to the audience without changing the facts. Reports and posters follow an order: question, method, results, conclusion with limits, references. Graphs need titles, labelled axes and units. In demonstrations and exhibitions, show the idea in action and invite questions. In the media, claims often grow bigger than the evidence, and everyday words like theory mean something different in science. Check the source, the evidence, the sample size and whether others confirmed it.
- Ethics in Science and Technology – Science and technology give great power, so we also ask "should we?" and not only "can we?". Science ethics means weighing benefit against risk, keeping people, animals and nature safe, being honest with data, taking responsibility for how results are used, and letting citizens share in big decisions about science.
