“Sewer Lice” (pdf) is a Flinn Scientific, Inc. demonstration for “What Is Life?” to introduce some levity into the classroom and to provide an opportunity to discuss the importance of careful observations. One teacher from the NSTA ListServe suggested using white or golden raisins to make them harder for students to recognize.
“The Scientific Method” activity has students write a paper about the scientific method and then use it to solve a problem. Rubrics are included.
