This lesson introduces the scientific method as the fundamental framework for discovery and problem-solving in biomedical science. In Ghana, we face numerous health challenges, from infectious diseases like malaria and cholera to rising cases of hypertension and diabetes. Understanding the scientific method empowers students to move beyond superstition or guesswork and embrace a structured, evidence-based approach to understanding and addressing these health issues in their own communities. It is the tool that scientists at Noguchi Memorial Institute, Kintampo Health Research Centre, and hospitals across our nation use every day to improve our lives.
A. What is the Scientific Method?
The scientific method is a systematic, logical process of inquiry used by scientists to explore observations and answer questions. It is not a rigid, linear set of rules, but rather a cycle of steps that guide investigation. Its goal is to acquire knowledge and understanding of the natural world based on evidence, not opinion or belief. In biomedical science, it is the cornerstone for everything from testing a new drug to identifying the cause of a disease outbreak. B. The Steps of the Scientific Method
We will explore a common 6-step model. It is important to remember that scientists may sometimes repeat or re-order these steps as their investigation progresses.
Step 1: Observation This is the starting point. It involves noticing something in the natural world that sparks curiosity. It could be something you see, hear, or read about. Definition: The act of gathering information using one's senses (sight, hearing, etc.) or through data collection. Ghanaian Example: A community health nurse observes that in a particular village, the rate of children suffering from diarrhoeal diseases is much higher than in the neighbouring village.
