Presents a fun-filled activity in which students create the perfect Kool-Aid recipe. Incorporates chemistry, cooperative group skills, experimentation, and recording of results. (JRH)

Describes a fifth-grade science classroom where students were asked to invent an operational definition of matter and validate that definition by designing and implementing a variety of tests. Challenges students to confront their misunderstandings about matter and move beyond merely reciting a definition. (JRH)

Describes activities for starting the school year that allow students to begin learning laboratory skills and also gives them a chance to meet and interact with classmates in a relaxed atmosphere. (JRH)

Describes a format for experiments where students not only conduct their own experiments but also become part of a model scientific community by writing research proposals, applying for grants, submitting their work to colleagues for scrutiny, participating in a symposium to present their findings, and creating a scientific journal to publish…

Presents an activity where students are gently guided through the stages of scientific investigation as they work on the problem of extracting salt from a simulated ore sample. (JRH)

Presents three articles that describe different ways of teaching the scientific method using cookies ("The One-Hour Science Fair"), cola ("Are All Medium Colas the Same Size"), and television ("Timing Televiewing"). (PR)

Presents an interdisciplinary activity that combines math and science and enhances cooperative learning skills. Enables students to learn about the scientific method by designing an original research project, collecting and interpreting data, and drawing conclusions based on their research. (JRH)

Describes an approach to teaching the scientific method where an outbreak of cholera within the school is simulated. Students act like epidemiologists in an attempt to track down the source of the contamination. (PR)
