The lab journal that students compile for this study can be designed for the level of classes taught.

In Pre-AP* biology, the following criteria have been used.

Problem:

Hypothesis: If, then format.

Observations: In paragraph form.

Data Chart:

Name of Organism Seen	Prokaryote or Eukaryote	Kingdom Classification	Heterotroph or Autotroph	Population Count
