比尔教科学 - Season 5 Episode 7 第 7 集
Do-it-yourself science involves a question, observations, a hypothesis, and experimentation. You have probably come up with questions after you noticed something unusual. For instance, why do fingers get all pruny and wrinkled when I sit in the tub? The observation – shriveled fingertips – is the first step. Do-it-yourself science requires an eye for details surrounding your observations. Collecting related information helps you get to the next step, what scientists call a hypothesis, or “educated” guess. After weighing all the evidence, you hypothesize that your fingers get pruny because of the hot water in the tub. Once you have a hypothesis, it’s time for the fun part – testing it out.
