The Nature Of Science

Chapter 1 Section 1 Continued…


Experiments
Experiments

  • One thing that all experiments have are variables. Variables are the different factors that can change in an experiment.

  • There are three types of variables we use in experiments

    • Independent variables

    • Constants

    • Dependent variables


Experiments1
Experiments

  • Independent variables- These are the variables that change in your experiment

    • So for example, in yesterdays demonstration with the Coke and Diet coke the variables where the coke and diet coke. Because I didn’t just test only the diet coke, or only the regular coke.


Experiments2
Experiments

  • Constants- These are the variables that don’t change in an experiment.

    • So yesterday some of the constants were the amount of water in the tank, the size of the cans, the material that made the can.


Experiments3
Experiments

  • Dependent Variables- this is the variable being measured.

    • Again in the coke vs. diet coke experiment the dependent variable was how well each can floated.


Experiments4
Experiments

  • Also there are controls. Controls are not always used in experiments but often are. Controls- are a standard to which your results can be compared.

    • A control we could have used, but we didn’t would be a coke can full of water. This would have shown us that the metal can does not affect the buoyancy.
