Scientific Papers
Date:
Scientific Papers• Scientists use a specific format for writing
papers (lab reports)• Four Parts – all in third person– Introduction – contains real world correlation,
research, purpose, & hypothesis– Materials and Methods – the experiment that was
done (past tense) – include problems– Results – contains the data (in tables often)– Conclusion – the analysis of what your data means
(bigger picture) and any possible errors, funnel back out to real world
Evaluation of Scientific Paper
• Group down to two• Read through rubric• Read through paper• Evaluate points– I know what I gave this report, let’s see how close
you are!
