Varaibles in a Science Experiment
M. O'Grady-Jones
This project is part of my work towards an Ed.D. in Educational Technology. The following link will take you back to my class page for EDET 703- Technology Tools II.This project was originally concieved as a PowerPoint prototype of a learning module. The original PowerPoint can be accessed through slide share. OGrady-Jones Variables in a Science Investigation
Welcome!
This site was designed to help you learn about variables and why they are important to a science experiment. In the past, you have modeled experiments that were already designed for you so you did not have to worry about variables. Those decisions were already made for you.
As a 5th grader, you will get to design some of your own experiments this year. As a scientist, you will need to know more than just questions and hypothesis. You will need to know that there are three types of variables. You will also need to know where and when to use each one in a science experiment. I recommend that you follow the links in order below, but you are free to explore. Click on the images below to begin.
Learning Goals.html
This section outlines the learning goals for this website.
What is a variable?
This section will give you a general overview of variables.
Manipulated/Independent Variables
This section provides information about the variables that scientists change in an experiment.
Control Variables
In this section, you will learn the definition of control variable and how to choose the control variable in a scenario.
Responding / Dependent Variables
In this section, you will learn the definition of responding/ dependent variables and how to identify them in an experiment.
Relationships Among Variables
Now that you have mastered all these variables, you will learn how they impact each other. You will look at patterns and trends that will show up in the results of an experiment.
More Practice
This section will let you practice identifying all 3 types of variables in a scenario..
