introduction

a biology investigation usually starts with an observation—that is, something that catches the biologist’s attention. for instance, a cancer biologist might notice that a certain kind of cancer can't be treated with chemotherapy and wonder why this is the case. a marine ecologist, seeing that the coral reefs of her field sites are bleaching—turning white—might set out to understand why.

how do biologists follow up on these observations? how can you follow up on your own observations of the natural world? in this article, we’ll walk through the scientific method, a logical problem-solving approach used by biologists and many other scientists.

the scientific method

at the core of biology and other sciences lies a problem-solving approach called the scientific method. the scientific method has five basic steps, plus one feedback step:

make an observation.

ask a question.

form a hypothesis, or testable explanation.

make a prediction based on the hypothesis.

test the prediction.

iterate: use the results to make new hypotheses or predictions.

the scientific method is used in all sciences—including chemistry, physics, geology, and psychology. the scientists in these fields ask different questions and perform different tests. however, they use the same core approach to find answers that are logical and supported by evidence.

scientific method example: failure to toast

let's build some intuition for the scientific method by applying its steps to a practical problem from everyday life.
