Activity: Tracing Steps	Page 2 of 3
Each step is a natural lead-in to the next step. Wondering about something leads you to do some library research about the topic. This research helps you form your hypothesis. Once the hypothesis is formed, the next step is to try it out by experimenting. After you experiment, you will want to analyze the results to see if you can answer the question.
Review some DNA examples of these steps, using Oswald Avery’s research as an example. Print the worksheet by clicking here. It describes several DNA examples and asks you to determine which step in the Scientific Method is being described.   Oswald Avery’s experiments showed that DNA must be the “transforming principle” or the genetic material in cells.
