Maintaining accurate records of observations and measurements is a key component in this systematic method. Every student should keep accurate chronological records, possibly in a scientific investigation journal or science lab book, of everything done in the investigation. These notes should be placed within each student's portfolio for assessment purposes. Resources for basic information are essential to scientific investigations. Many of these resources are available to the general public and contain lots of information on a variety of subjects.
