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
