If you want your students to really understand the scientific process and experimental design, they need time and practice. We use this rubric over and over throughout a school year to help guide our research and experimental practices.
This rubric can be used by the teacher, by students as a peer review. See my other FREEBIE Scientific Lab Report Headers For Mini-Poster
! The goal is that students become so familiar with the process (and this rubric) that eventually it becomes second nature.
