Put these steps in a helpful order for iterative, evidence-based research after you have an initial idea.

Update your belief and plan replication or a follow-up study
Run the study and summarize the outcome relative to $H_0$ vs $H_A$
Preregister variables, exclusion rules, and the analysis plan
State $H_0$ and $H_A$ (including predicted direction if you have one)
Refine the hypothesis (e.g., add scope conditions) and test again

About this course

Builds scientific reasoning through the practices of experimental design, measurement, and data interpretation. Surveys chemistry of life—atoms, bonding, water, pH, and buffers—and the structure–function of macromolecules. Explores cell structure, membranes and transport, and enzyme-driven metabolism and energy coupling. Introduces information flow from DNA to RNA to protein, inheritance fundamentals, and qualitative genetics. Connects homeostasis with introductory human physiology, and frames evolution and ecology, including energy flow and biogeochemical cycles. Emphasizes laboratory safety and technique, quantitative literacy, figure reading, and responsible conduct and bioethical considerations.
