Lesson 3 Lab : Constructing and Testing a Calorimeter. Use the multimedia presentation for this investigation to record the data for the first trial in this experiment. Create a table like the one below and fill in the appropriate values. Indicate what trial(s) that are outliers and therefore eliminated from your calculations. (Hint - An outlier trial will have values that are different than all a value that is common for all other trials).
