4. Results and Discussion. THIS IS THE MOST IMPORTANT SECTION IN THE REPORT; An effective discussion should uniquely define your experiment while also demonstrating your abiility to select the appropriate data to include, to discuss your understanding of the results in the context of the overall experiment, and to think critically and write logically Chemistry Lab Report Format Lab reports may be handwritten on notebook paper or typed. Pre-labs are due the day we perform the lab. Post-labs are due one week after we perform the lab (you can always turn them in sooner). Every section should be written in complete sentences . This section should be complete enough for a trained scientist to pick up your report and replicate your experiment. The experimental section in a laboratory report is more concise than the corresponding section in the laboratory notebook Form 4 - Chapter 1 : Pendulum (Experiment) To investigate how the period of a simple pendulum varies with its length.
