    Study Notes

    Plant Growth and Response

    • A plant growing towards a window is an example of a response to stimuli.

    Bacterial Growth

    • A scientist hypothesizing that temperature affects bacterial growth rate should grow bacteria at different temperatures and measure growth rates to test the hypothesis.
    • Observing bacteria in different environments or reading about bacterial growth in textbooks is not the best way to test this hypothesis.

    Evaluating a Research Claim

    • When evaluating a claim that a plant can purify polluted water, the researcher's reputation is a crucial factor to consider.
    • The plant's appearance and growth rate also play a role.
