OVERVIEW OF RESEARCH METHODS

THREE PILLARS OF EXPERIMENTAL RESEARCH

Scientific Method - Controls and Variables

 It is a type of research where the researcher manipulates one variable while controlling the rest of the variables.  It is usually conducted to explain.

Experimental Design. Learning Targets I can… Identify the three types of variables in an experiment Identify quantitative and qualitative data Decide.

 Make an Observation  Then Ask a Question!  Perform research about your question  Use only credible sources .edu,.gov,.org  Cite your resources!

Control: The part of the experiment that scientists keep the same during the experiment ex: temperature, location, light. Control Group: The group in the.

The Scientific Method Defined: step by step procedure of scientific problem solving (5) Major steps are listed below.

The Controlled Experiment Why It Is So Important To You!!!!

Parts of an Experiment

Controls There are usually many controls... Factors in an experiment that are held constant (the same) from one part of the experiment to another There are usually many controls...

Trials Can be one or as many as you wish The number of times an observation or measurement is made during an experiment Can be one or as many as you wish

What Parts Are There? 1. Variables: factors that change in an experiment 2 Types: Independent Variable Dependent Variable

Independent Variable The variable that is purposefully changed or manipulated in an experiment This is where you make the desired changes to test their results!!! Get it...change?

Dependent Variable Variable that changes in response to manipulations of the independent variable The outcome of the dependent variable DEPENDS on the independent variable!!! Get it, depends?
