As stated in the text, there is no one scientific method. However, making observations, formulating hypotheses, and performing experiments are generally components of “doing science.” Read the following passage, and list any observations, hypotheses, and experiments. Support your answer.
Joyce and Frank arc eating raisins and drinking ginger ale. Frank accidentally drops a raisin into his ginger ale. They both notice that (lie raisin falls to the bottom of the glass. Soon, the raisin rises Lo the surface of the ginger ale, then sinks. Within a couple of minutes, it rises and sinks again. Joyce asks. “I won der why that happened?” Frank says. I don’t know, hut let’s see if it works in water.” Joyce fills a glass with water and drops the raisin into the glass. After a few minutes, Frank says, “No, it doesn’t go up and down in the water.” Joyce closely observes the raisins in the two glasses and states, “Look, there are hubbies on the raisins in the ginger ale but not on the raisins in the water.” Frank says, ‘it must be the bubbles that make the raisin rise.” Joyce asks, “OK, hut then why do they sink again?”
