Terms of use

By using Lab Dossier, you agree to the terms below. If you do not agree, please do not use this site.

Educational use

Lab files, reference pages, tools, and printables on this site are free to use for classroom and personal educational purposes, including printing student copies for a class you teach. Republishing our written content elsewhere as your own, or reselling our printables, is not permitted without written permission.

Safety is your responsibility

Lab files describe procedures that involve heat, chemicals, glassware, or other hazards common to a science classroom. Every lab file lists a hazard level and safety notes, but the adult supervising an activity is responsible for judging whether it is appropriate for their students, their space, and their school's own safety rules — this site cannot make that judgment for you. Follow your school or district's official safety policies first.

No warranty

Content is provided "as is." While every lab file and calculation is checked before publishing, we cannot guarantee that every page is free of errors, and we are not liable for any outcome from using the information on this site. If you find an error, please report it through the contact page.

Tools

Browser tools on this site are provided for practice and convenience. They are not a substitute for a teacher's own grading or a student's own understanding of the underlying concept.

Changes

These terms may be updated from time to time. Continued use of the site after a change means you accept the updated terms.
