Scientific Method

A series of steps used by scientists to solve a problem or answer a question.

• Record Data

• Scientific Method

• Hypothesis

• Data Analysis

A possible explanation to a question or problem; must be testable

• Question

• Independent Variable

• Hypothesis

• Background information

A factor in an experiment that can be changed

• Variable

• Constant

• Control

• Data

an experiment where only one variable is changed at a time

• Constant Experiment

• Variable Experiment

• Controlled Experiment

• Experimental Design

the group that does not received the treatment, the natural conditions, used for comparison (ex: the plant that receives a normal amount of daily sunlight)

• experimental group

• control group

• constant

• hypothesis

the group that received the treatment, the group that you change (example, the plant that receives extra light)

• experimental group

• control group

• constant

• problem

the variable that is deliberately changed (I change), is plotted on the x-axis

• constant

• independent

• dependent

• hypothesis

the variable that is measured, affected by the independent variable

• dependent variable

• independent variable

• constant

• data analysis

all other variables that need to stay the same

• control

• qualitative data

• constant

• independent variable

descriptions that involved characteristics that cannot be counted (color, texture, smell, etc)

• constant

• qualitative data

• quantitative data

• conclusion
