Conduct Research and Generate Questions Practice Test

In a 1-week science mini-project, Maya wonders: “Do different brands of bottled water contain different amounts of microplastics, and how do researchers measure them?” She uses 4 sources: (1) a short scientific article summarizing microplastic-counting methods (filtration + microscopy), (2) a consumer lab website explaining contamination risks during sampling, (3) a news report about microplastics in bottled water, and (4) an interview email with a local university lab tech about basic lab steps. She writes an answer that compares what the sources agree on (contamination control matters) and what they differ on (which method is most accurate), then suggests next steps. Which set of additional questions best extends her research in multiple focused directions for another few days of work?

For a 4-day health mini-inquiry, Lila writes the research question: “How does sleep affect teenagers?” She has access to 3 sources: a children’s hospital webpage on teen sleep, a short psychology article about sleep and memory, and a school counselor interview. Which revision best improves the question’s focus while keeping it open to research and answerable in a few days?
