Phase Lab Errors

Select the acceptable EXPERIMENTAL error or errors for this lab from the list below. When picking out an experimental error don't be fooled. Think about two things: (1) Would this have affected your observed value and (2) Is this a human error that you should have fixed right away if it happened. Pick and discuss the experimental error or errors in your third paragraph. Don't forget to include suggestions on how to fix them.

• Sharing a hot plate

• All the ice blocks were different sizes

• Reading the thermometer incorrectly

• The thermometer is not calibrated* properly due to age

* Calibrating is making sure that the tool you are reading is set properly. For example, when you are using the balance, you need to make sure it is set at zero with nothing on it.
