1 What is Science?Science – A way of learning about the natural world. Uses observation and logical reasoning.Scientific Inquiry – Refers to the various organized methods of investigating problems & answering questions (Lab Investigations)..
2 What is Science?Physical Science – The study of matter and energy and the changes that matter and energy undergoSkills Used By Scientists – Posing questions, making observations and inferences, developing hypotheses, and conducting experiments –
3 What is Science?Posing Questions – Curiosity drives scientific inquiry.Observing – Involves using all 5 senses – sight, hearing, touch, smell , & sometimes taste -
4 What is Science?Data – The facts, figures, and other evidence that you learn through observation.Inference – A logical conclusion based on observations or prior knowledge. (An Understanding)Hypothesis – A possible explanation for observations that relate to a scientific question
5 What is Science?Variables – The factors that can change during an experimentIndependent Variable ( Manipulated) – The variable the scientists changes.Dependent Variable (Responding) – The condition that is expected to change because of the Independent Variables.
6 What is Science?Controlled Experiment – An investigation in which all variables except one (The Dependent Variable) remain the same or are controlled. Only one factor is changed.Qualitative Data – Descriptions, Sounds, Colors, or Odors –Quantitative Data – Numerical data: Numbers Measurements made using standard units (the SI or metric system) For Example: Temperature = 400 C or Speed = 100 km/sec
7 What is Science?Interpreting Data – Finding out what the data means by identifying patterns and trends.Conclusion – States whether your data proves your hypothesis is True or FalseCommunicating Your Information – may be done by: a. Writing articles for journalsb. Speaking at scientific meetingsc. Using the Internet
8 What is Science?Scientific Theory – A well-tested idea that explains & connects a wide range of observations.Scientific Law – A statement that describes what scientists expect to happen given a certain set of conditions. For Ex. Gravity
