How to Document Results From Lab Experiments

Recording the results of laboratory experiments is an important part of scientific research. Proper documentation preserves the experimental observations and data for future reference, and helps to protect intellectual property rights. It also provides an opportunity for researchers to organize their thoughts, prepare for papers and communicate with the rest of the scientific community. Experimental results are recorded in a laboratory notebook. Different laboratories may have specific requirements for recording results, but a few basic rules apply to most situations.

Things You'll Need

Laboratory notebook
Pen with blue or black ink
Glue

Instructions

- 1
  Record the background information for the experiment. This includes the dates the experiment began and ended, as well as the time of day, with a.m. and p.m. designations. Also include the title of the experiment, where it was performed and the full names of lab partners and associates. Always record information with blue or black ink.
- 2
  Write down the chemicals and equipment used in the experiment. The information for the chemicals should include the chemical name, manufacturer and lot number. For the equipment, record the manufacturer, model and serial number. Also write down any changes or adjustments made to any of the equipment, such as recent calibration, as well as the settings used on the instruments.
- 3
  Record the data and observations. Data is usually recorded in chronological order. Be sure to include all of the data, even if it seems off or may have errors. Include units with all numerical values and show all calculations.
- 4
  Attach any additions. Graphs, charts, photographs or any other extras should be attached to the notebook with glue. Never staple or paper clip additions. Make sure the glued additions do not obstruct page numbers or data.
- 5
  Have it witnessed. When the results section is finished, ask another person to read, co-sign and date it. In most labs, this "other person" will be the lead scientist or principal investigator. In other labs, it will be a coworker or another scientist. Some laboratories require two witnesses.
