Conducting Your Trials

Use your experimental design on page 2 to complete three trials for each data point you are testing for your independent variable.

In order to measure the volume of each can you will need to fill it with water, then measure that amount of water using a graduated cylinder. This measurement should be taken before (initIal volume) and after (final volume) each can crush trial.

The formula to use for percent crush is:

 

 

 

If your group makes any known errors during a trial, you should consider that trial an outlier and complete it again.

Referenced Questions

These questions were answered in the previous steps. They are provided here for your reference.

Which variable will be your independent variable?

What measurements will you use for your independent variable?

(For example, if you are changing the amount of water in the can, you might use 5 mL, 10 mL, and 15 mL.)

List the three variables you will hold constant in your experiment.

What set measurements will you use for each of your constants?

Questions

Please answer the questions below.

Fill in the data table below with your percent crushes as you complete three trials for each data point that you are testing. Then calculate the average percent crush for each data point.
