BIO 220 Scientific Method Matching Exercise guide

The exercise has two graded halves and the second is where the marks live. Part I is the matching itself: seven scientific-method steps against seven lettered examples from a single running scenario — a scientist investigating whether industrial waste water accelerates algae growth in a pond. Part II requires a because-sentence for every match, and that is the half that distinguishes a submission that understood the method from one that pattern-matched vocabulary. The scenario is built with deliberate near-misses: an observation (noticing the pond by the plant has heavier algae growth) reads a lot like a question (wondering whether the waste water causes it), and both read close to the hypothesis. The discriminators are grammatical as much as scientific — the hypothesis is the only if-then prediction, the question is the only sentence that wonders rather than asserts, and the observation asserts a noticed pattern without proposing anything.

Work the unambiguous anchors first and the hard three fall out. The experiment is the only example with a manipulated setup — two dishes, one receiving waste water, one control receiving none — and naming that control dish in your Part II reasoning is exactly the kind of specific the rubric's 'explain your reasoning' wants. Data collection is the measuring act five days later; interpretation is the comparison that finds twice the algae in the treated dish; reporting is the journal submission. Each because-sentence should name the defining feature of the step, not restate the example: 'this is data collection because it records a measurement without yet drawing a conclusion' does the work, while 'this matches because the scientist measures algae' merely repeats the prompt. The exercise says GCU style is not required but solid academic writing is expected — complete sentences in Part II, not fragments.

A cleaning note matters for this record: the scraped page glued an unrelated neuroscience assignment's rubric (neuron anatomy, subcortical structures) after Part II, behind platform navigation chrome — it belongs to a different course and is excluded from the brief above, so do not chase its point values. The actual exercise is worth 75 points and its structure tells you where they sit: seven matches and seven reasoned justifications, weighted toward the reasoning. If you want the method itself firmer before writing, the open textbook treatments of the science of biology walk the same seven moves through worked examples, and the Berkeley understanding-science material is useful precisely because it complicates the tidy sequence — real inquiry loops and backtracks — which gives your Part II answers the extra sentence of depth that separates accurate from thorough.
