  1. What is Science?What is Physical Science?What will we be learning about in this class? Getting it all started…

  2. What is Science? • The study of the (relatively) simple and small number of rules that govern the universe • Science is sometimes referred to as “a body of knowledge” • Science is sometimes referred to as “a process”

  3. Space & Time The universe we will be studying is VERY big and VERY old Matter & Change The stuff in the universe has been here forever, it just goes through changes Forces & Motion Forces cause things to change what they are doing Energy The ability to “do stuff” can be transferred from one object to another “Big Ideas” of Physical Science

  4. Science vs. Technology • Science is the pursuit of knowledge for the sake of knowing • Technology is the application of knowledge to solve a specific problem

  5. The Scientific Attitude • Some Key Terms: • Fact • Law • Theory • Hypothesis

  6. Facts • Close agreement of observations of the same phenomena by a number of different observers • Facts are objective – report what happens, not what you think should have happened • “Rising Sun” example • Facts can change, based on new observations, conditions or experiments

  7. Scientific Laws • A statement summarizing facts after repeated observations • Scientific Laws DO NOT explain why something happens – they only tell you what happens • “Rising Sun” example

  8. Scientific Theory • Using facts and laws to come up with an explanation for why things happen • Scientific theories can be used to make predictions about what will happen next • “Rising Sun” example

  9. Hypothesis • An educated guess about what will happen in the future, based on facts, laws, and theories • Used to guide testing and experimentation

  10. Scientific Attitude • Findings must be accepted, regardless of whether they fit what we think should happen, or not • “Falling Ball & Paper” • Facts, Laws, and Theories are not set in stone – they need to be adjusted if a new observation contradicts what was previously known
