How to write a science Lab Report
** your introduction should be in the present tense when stating theory and background information**
b) The Purpose statement
The purpose of this experiment was to investigate.....
Eg. The purpose of this experiment was to investigate the effectiveness of three paper towel brands, Bounty, Royal, and No Name, on the removal of 3 mL of milk spilled on a wooden surface.
Eg., It was hypothesized that if the cost and thickness are related to the effectiveness of the paper towel on absorbing 5-ml milk spillage, then Bounty would be the best to absorb the milk spill since it is composed of quilted paper that adds to the thickness of the paper towel. In addition, the price of a roll of bounty containing 1000+ sheets is substantially more (by about$1.00) once compared to the other paper towel brands investigated in this experiment.
Independent variable: Name of the paper towel
Dependent variable: Effectiveness of absorption
Eg. The piece of Bounty paper towel remained intact even after multiple trails.
Note: Only list properties relevant to the experiment. For example, even though the paper towel was white, this has no effect on the outcome.
Eg., As an improvement, the microfiber could be tested since one would also assess the environmental implications of using such product along with paper towels....Different substances could also be used to test the effectiveness of the paper towels.
....A source of error was a flat surface was used, hence the area of spillage was no constant.
