What is the scientific method
A sequence of events that are used to determine if a hypothesis is supported or rejected. Procedure, investigation
The first step of the scientific method is determined by collecting information by our senses. It is called the
Observation, Question, Problem
Before we make a hypothesis we must ____________________________. It is the reason that the hypothesis is considered "educated"
research
This is the process of collecting information from the experiment.
Collecting data
What do you use the data from your experiment for
Support or reject your hypothesis
This is the "If" part of your hypothesis
What the scientist changes
The independent variable
The experimental group
The manipulate variable

If I change this then I will see this happen
The condition that is changed in an experiment
variable
The expected change / data collected
The "Then" of the experiment
What the scientist expects to happen
The "Then" in the hypothesis
The dependent variable
The responding variable
An attempt at an explanation about an event or phenomenon that is first researched and can be experimented.
Hypothesis
This is the testing of a hypothesis
