Predicting and extending experiments — ACT practice questions
ACT Science items on Predicting and extending experiments ask students to use a study's design, tables, and figures to forecast what would happen if a procedure were changed, repeated, or carried further. A student must keep independent and dependent variables and controls in mind and pick a next step that actually tests the stated hypothesis. Questions usually follow a research summary and offer short choices describing a new trial, a predicted trend, or an extra measurement. Common traps include reversing cause and effect, stretching a trend past the given data, and varying the wrong factor.
