Analysis
Results from Trial __ and Trial __ are within __% of each other. This comparison can be made because the object tested was the same Trial was by ______ method Trial 2 was by _________ method. The preferred method is _______.
Conclusions
The density of a small wooden block (id # 4) was determined to be between _____ g/cm3 and
______ g/cm3. The irregular object (id # 721) was determined to have a density of ____ g/cm3
The density determinations can be trusted with about ___% based on the comparsion of the wooden block and two different methods of measuring. In future we may be able to increase our confidence in the answer by avoiding.
It is reassuring to note that the more dense object in fact sank in water and was found to have a density greater than 1.00 g/cm3, whereas the wooden block which floated was found to have a density of _____ which is less than 1.00 g/cm3
