Introducing a new representation of the process of science
Students begin with a simple "warm up" activity that introduces them to the process of science. The class discusses whether or not they were "doing" science. Students then read a story about the geoscientist, Walter Alvarez, and identify phrases within the story that indicate that Alvarez was doing science. Students are introduced to the Science Flowchart and are asked to plot the scientific journey of Walter Alvarez. Students find that science is seldom a linear story, but instead involves unanswered questions, surprising leaps, reinterpretation of data, and the unexpected.
- The process of science involves testing ideas about the natural world with data from the natural world.
- Scientific understanding improves as new evidence and perspectives emerge.
- The process of science is non-linear.
- The process of science involves observation, exploration, discovery, testing, communication, and application.
- Scientists test their ideas using multiple lines of evidence.
- Test results sometimes cause scientists to revise their hypotheses.
- Scientists are creative and curious.
- Scientists work together and share their ideas.

Teaching Notes and Tips
As there are two versions of the Science Flowchart, you may want to have a two-sided sheet — one side shows the simple version and the other the complex. Place the sheet in a plastic sleeve and cover the complex side with colored paper so that only the simple version is visible. Once the students are ready to see the complex version, they need only remove the colored piece of paper.
