An Experimental Investigation is used to test an idea by changing one factor called a variable. By changing only one variable, you can see how it affects the outcome of the experiment.
Independent Variable the variable that you, the experimeter can change.
Independent Variable = Cause
Dependent Variable the variable you are measuring, that may change when you change the independent variable.
Dependent Variable = Effect and Result
Constants all other variables must remain the same for the experiment to be fair.
Experimental Investigations require knownledge or previous experience. Sometimes you may need to research the topic before beginning the experiment.
Hypothesis Knowledge will be used to write a hypothesis. You should tell how you will change the independent variable and predict the effect it will have on the dependent variable.
The three key words for Hypothesis are If, Then and Because
Hypothesis is a guess Remember a hypothesis does NOT have to be right... this is your guess and you run the experiment to see if you guessed right or wrong!
Control is the experiment setup without changing the independent variable.
Experimental Investigation Summary Part 1 An experimental investigation is a fair experiment that tests only one Independent Variable (cause) and measures/records a Dependent variable (effect).
Experimental Investigation Summary Part 2 Before the experiment, a hypothesis is written to guess how changing the Independent Variable in a certain way will affects the Dependent Variable.
