1.1, 1.2, and 1.3
Term | Definition |
---|---|
Scientific Inquiry | The way in which scientists study the world and produce explanations based on data |
Hypothesis | A possible answer to a question that can be tested |
Parameter | Factors that can be measured |
Manipulated Variable | Variable that you can change (Independent) |
Responding Variable | Variable that changes in response to the manipulated variable (Dependent) |
Data | Facts, figures, and other information gathered from experience |
Qualitative Data | Observations or data that don't involve numbers |
Quantitative Data | Observations or data that involve numbers and measurements |
Communicating | When you share your results so others can repeat and check your results |
Model | A picture, diagram, or computer image that shows and object or process |
Scientific Theory | A well tested explanation of observations or experimental results |
Scientific Law | What scientists expect to happen every time under certain conditions |
Science | Study of the natural world |
Observing | Using two or more senses to gather information |
Inferring | Explaining your observation |
Predicting | Making a statement about the future |
Chemistry | Properties of matter and how it changes |
Physics | Study of matter, energy, motion and forces |
Controlled Experiment | An experiment in which only one variable is manipulated at a time |
Graph | Picture of data |
Horizontal Axis | Line that runs left and right (Independent/manipulated variable) |
Vertical Axis | Line that runs up and down (Dependent/responding variable) |
Origin | ( 0 , 0 ) |
Coordinate | Pair of numbers that tell the position of a point |
Data Point | Shows location of the intersection of data |
Line of Best Fit | Reflects general pattern of a graph |
Linear Graph | Where points form a straight line |
Slope | Tells you how much Y changes for every change in X |
Nonlinear Graph | Data does not fall along a straight line/can't draw line of best fit |
