What are the Different Types of Experimental Variables? Variables are anything in an experiment that can change on its own or can be changed. Types of experimental variables are: independent variables, dependent variables, controlled variables. Independent Variable (IV) An independent variable is a variable that is purposely changed. The purpose of an experiment is […]
Growing Rock Candy: Variables
Experiment for Growing Sugar Crystals Variables Dependent Variable: amount of sugar crystals collected Independent Variable: The independent variable is a part of the experiment that if changed could affect the dependent variable.I have identified all the possible independent variables in the following descriptive experiment. Notice that instead of just making a list of the variables, […]
Variables For Making Rock Candy
A Science Fair Project is a cause/effect investigation. The cause is called an independent variable (something you purposely change). Changes in the independent variable affects another variable called the dependent variable. You AFFECT the investigation by making changes in the independent variable. The objective of the investigation is to measure the EFFECT that this change […]
Crystal Project: Variables
A variable is something that can change. For your science fair project, you should change one variable to see what affect it has on another variable. These two variables are: independent variable: Something that you choose to change. dependent variable: Something that changes in response to changes in the independent variable. 1. Following are ideas […]
DNA: Project Variables
Step 3: Variables (things that can change) Variable is the name given for any part of an experiment that changes. For example, the following question identifies what is happening as well several variables which are identified. Note: The Question is an example for identifying variables–but is in the form of writing a science fair project […]
