Lab ReportsA written record of science

What is a Lab reportTool to record data and process in

a clear format.A method to give others the

ability to reproduce your experiment.

A document of your actions and findings.

Why do we do lab reports?To help develop clear

communication skills.To focus and direct our findings in

a comprehensive manner.To allow for later review and easy

reference.

Formal Report Format1. Abstract2. Introduction3. Data & Observations (typed from lab

notebook)*4. Calculations (if any)*5. Summary of Results6. Discussion (including error analysis)7. Conclusion8. Reference

*Deviation from the ACS journal format is necessary for some parts of the report in order for instructors to check on students' laboratory skills and calculations.

for the raw data collected during the experiment)

IntroductionThis is a basic description of what you are going

to do and how.This does not include results or findings.

EXAMPLE:Penny Lab is to study electro-plating and metal

bonding to form a new alloy. The pennies will be placed in a solution of Sodium Hydroxide and dissolved Zinc metal to plate the copper with zinc. The pennies will be removed using tongs and some will be used for the second segment where the penny is heated to induce (cause) the alloy brass to form.

Data and ObservationsFirst, it tells what and how much

for each chemical and piece of equipment to be used.

Second, it details the basic steps of the procedure, sometimes this is placed in a section called procedure.

Last, it details what was seen and happened as the lab unfolded.

Calculations and SummaryCalculations are made for and

math needed for results. Just write out the formula with your numbers in the proper spots and show your answer.

Summary gives the basic review of the end outcome to the experiment.

Discussion and ReferencesDiscussion includes explanation

of what went well or wrong and how to improve the process or results. Suggestions for a new procedure or better one.

References include any other tools used to supply information, answers, or process data.

What to expectWe will have lab reports for every

lab.These will be graded and

checked (easy points if done)We will do only 3 formal lab in

this class.These skills are important for

anyone who ever has to make a report of an event.
