Describes the physical and chemical structure of zeolites and presents a series of experiments demonstrating some of the properties of these chemicals, including investigations of the hardness of tap water and the water-softening capabilities of various laundry detergents. Contains 13 references. (WRM)

Describes an activity on charting 6th and 7th grade students' ideas about a potential science project. Summarizes a five week project on creating a new ride or redesigning existing rides in an amusement park, including research and sketches, final drawings, models of rides, and class presentations. (YDS)

Describes a simple, small-scale experiment that can be applied at any stage in a chemistry course, including acid-base reactions, solubility, reaction rates, equilibrium, and problem solving. (WRM)

Reviews three projects that use a graphing calculator linked to a calculator-based laboratory device as a portable data-collection system for students in chemistry classes. Projects include Isolation, Purification and Quantification of Buckminsterfullerene from Woodstove Ashes; Determination of the Activation Energy Associated with the…

Describes a laboratory exercise that takes advantage of the abundant number of species of goldenrod galls that exist in the environment to explore a question concerning the behavior of the female gall-forming insects as they lay eggs on the goldenrod plant. (ZWH)

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 information and data on an experiment designed to test whether different atmosphere compositions are affected by light and temperature during both cooling and heating. Although flawed, the experiment should help students appreciate the difficulties that researchers face when trying to find evidence of global warming. (PR)

Describes how to approach block scheduling of science classes. Discusses the planning process, specific activities that work well in longer science classes, and techniques for motivating students. (DDR)

Presents ideas from elementary school teachers who have made hands-on science an integral part of their classrooms. Includes suggestions for overcoming obstacles to hands-on science, innovative teaching techniques that encourage girls to excel in science and math, model activities to win parent/teacher support, and a list of eight "sensational"…

Recommends a number of investigations using video-capture and two readily available, non-pathogenic larval Digeneans with contrasting life cycles and behavior. The activities support the hypothesis that parasites exhibit behavior that increases their chances of a host infection. (DDR)

Presents stories that illustrate how children learned lessons about the nature of science. These lessons include such ideas as observing closely and keep records, accessing resources, and collaborating with each other. Describes the use of a classroom bird station and nature walks in accomplishing the goals. (DDR)

Focuses on how one teacher examined classroom discourse through a unit on tornadoes and natural catastrophes. Defines various types of discourse and discusses how discourse in a 6th grade class was analyzed. Details some of the activities that engaged students. (DDR)

Science teachers must adapt curriculum materials, so preservice teachers must develop beginning proficiency with this authentic task of teaching. What criteria do they use when they critique these materials in preparation for adapting them, when they develop the criteria themselves and when they are given a set of criteria from which to choose?…

Reading "Harry Potter and the Sorcerer's Stone" aloud to her sixth-grade students inspired this author to create a mathematics activity based on budgeting for school supplies for Hogwarts School. In that lesson, each student was assigned a name from the Hogwarts School roster and allotted a different dollar amount for his/her budget. Students…

The brain is a truly fascinating structure! It controls the body and allows everyone to think, learn, speak, move, feel, remember, and experience emotions. Although the brain is a single organ, it is very complex and has several regions, each having a specific function. These functionally diverse regions work together to allow for coordination of…
