Writing Like Scientists at CVA

Formal lab report writing has been a cornerstone of the CVA Science Department for many years. First instituted by teachers and published scientists, Karen Lanoue-Egan, M.S., and Shelley Koenig, M.S., this practice now spans the science curriculum.
Formal lab report writing offers several key benefits to CVA students:
  • Improves scientific communication: Helps students clearly organize and express ideas using proper grammar and scientific terminology.
  • Builds data analysis skills: Teaches students how to organize, interpret, and draw meaningful conclusions from data.
  • Strengthens critical thinking: Encourages students to analyze results deeply, justify conclusions with evidence, and identify potential errors.
  • Develops precision and attention to detail: Requires accuracy in procedures, measurements, and explanations.
  • Prepares for college and research: Familiarizes students with the format used in higher education and professional science. Alumni frequently report feeling well-prepared compared to their peers in this area.
  • Enhances logical organization: Helps students construct clear, evidence-based arguments.

In 7th and 8th-grade Life and Physical Science classes, students begin developing their lab report writing skills with significant teacher guidance throughout the writing and revision process. As students progress into high school, they gain greater independence in their lab writing through courses such as Biology I and Chemistry, where numerous formal lab reports are required. In advanced courses, including Honors Biology II and Physics, expectations increase further, incorporating statistical analysis and requiring students to use these tools to strengthen their conclusions. Environmental Science also utilizes data analysis and presentation, and introduces students to writing a scientific abstract. 

The CVA lab report format is structured similarly to a scientific paper and includes the following sections:
  • INTRODUCTION: This section provides background information on the topic being investigated. Students are expected to incorporate material from class notes to reinforce key concepts. The introduction concludes with the purpose of the lab and a brief overview of how that purpose will be accomplished.
  • HYPOTHESIS:  A clear, testable prediction about the expected outcome of the experiment.
  • MATERIALS AND METHODS:  A detailed, step-by-step procedure that allows an outside reader to replicate the experiment exactly as it was conducted.
  • DATA:  Presentation of collected data in clearly organized tables and/or graphs.
  • RESULTS AND DISCUSSION:  A thorough analysis of the data that supports acceptance or rejection of the hypothesis. Students must reference specific data points in sentence form to justify their conclusions. This section also includes an explanation of why the results occurred, a discussion of experimental and theoretical sources of error, and thoughtful suggestions for improving the lab design. The section concludes with an evaluation of how effectively the lab achieved its intended purpose.

Formal lab report writing at CVA provides students with a strong foundation in scientific thinking, communication, and analysis. Students benefit from meaningful guidance and individualized feedback, supported by small class sizes, hands-on scientific experiments, and teachers with advanced degrees in science. As these skills develop from middle school through advanced coursework, CVA students gain the independence and precision needed for success in higher education and scientific research, leaving them well-prepared to meet and exceed expectations beyond CVA.
