Scientific Method A planned approach to solving a problem
Make Observations and form a hypothesis Test Hypothesis/Perform Experiment Define/Identify the Problem Organize and Analyze Data New Experiment Do Experiment and Observations Support Hypothesis? No Draw Conclusion Communicate Results Yes Faulty Experiment? A planned approach to solving a problem

Problem A well-defined question

Anything you see, hear, taste, touch, or smell
Observation Anything you see, hear, taste, touch, or smell (using your senses)

Implying a conclusion based on observations
Inference Implying a conclusion based on observations

Hypothesis An educated guess

Experiment A test of the hypothesis

Procedure The step by step plan for the experiment

Variable = Size of the Ball
Anything that changes during the experiment 2 Types: Independent & Dependent Variable = Size of the Ball

Independent Variable The variable that YOU change in the experiment
50 mL water 100 mL water 200 mL water

Dependent Variable The variable that responds to the independent variable What changes because YOU changed something = Height of Plant (affects) 50 mL mL mL

Same size/color/type of flower
Control/Constant The factors that are kept or stay the same in the experiment Same amount of soil Same size/color/type of flower Same amount of light

Collect & Analyze Data Information collected from the experiment
Usually displayed in the form of a chart, table, or graph

Conclusion Forming an answer based on the interpretation and analysis of data

Classify To sort objects and/or organisms into categories

Model A structure that visually represents real events or objects

Models cannot show us everything about what they represent
Limitation Models cannot show us everything about what they represent
