Build a 1951 Laboratory Notebook

Jennifer and Daniel learn that scientists write things down carefully. In this activity, students create their own Rosalind Franklin-inspired lab notebook and practice recording observations like real scientists.

The goal is not to make a perfect answer. The goal is to observe, measure, describe, revise, and think.

Image suggestion:
A vintage-style notebook page with sketches of DNA, Photo 51, a microscope, and handwritten observations.

Materials:
Notebook or folded paper booklet, pencils, ruler, markers, glue, printed labels.

Activity:
Children design a lab notebook with sections: Question, Materials, Observation, Sketch, Evidence, What I Think, What I Need to Test Again.

Optional experiment pairing:
Use this notebook with the crystal activity or strawberry DNA extraction.

What children learn:
Good science depends on careful records, not memory alone.
