Name Partner(s) (2 pt penalty) ONYEN Experiment 1: Mass Volume and Density In-Lab Notebook (Results and Observations) Record your general measurements, recorded data and observations directly into this section during the lab. Data can be transcribed directly into the tables provided below. • Present your data in the figures and tables below. • Summarize your observations during the progress of the experiment. Observations should not include numbers (measurements). • Tables should be accompanied by a caption which helps the reader understand what the datameans and what conclusions can be drawn from the data in the table. • Always fill in units in tables - in parentheses below. To avoid confusion, do not add units to numbers, but instead to data headers or labels (such as what was done in the Excel tutorial) • Add observations between data tables to log what you see during the experiment (1-2 sentences is usually sufficient for any major steps - i.e. the volume increased noticeably when...)
