SCIENTIFIC INQUIRY CHAPTER 1 SECTION 2 PHYSICAL SCIENCE

PROCESS OF SCIENTIFIC INQUIRY Posing Questions  Answer questions by making observations  Not based on opinions or judgments Developing Hypotheses  Testable predictions to a scientific question  It doesn’t have to be right

Designing Experiments  Measure hypothesis by doing an experiment  Variables; manipulated (changes), controlled (doesn’t change) Collecting and Interpreting Data  Facts and figures from observations  Interpret data and make graphs and charts

Drawing Conclusions  What happened? Was the hypothesis right or wrong? Why? Communicating  Sharing your ideas by writing or speaking

HOW SCIENCE DEVELOPS Scientists use models and develop theories and laws to increase people’s understanding of the natural world. Scientific Models  Picture, diagram, computer image, or other representation of an object or process

Scientific Theories  A well tested explanation of your experimental results  Requires a large amount of evidence to support it Scientific Laws  Something that is expected to happen every time under a certain set of conditions  Describes a pattern in nature without attempting to explain it

LET’S PRACTICE Jimmy is eating outside and notices ants crawling toward his lunch. He wonders if they are going after his candy bar, or his carrot sticks. In a group, follow the steps of scientific inquiry to solve this problem.
