Describes an experiment involving the preparation of copper iodide that gives stoichiometric results. Materials needed and procedures are discussed along with ideas on different ways to analyze the data. Pertinent chemical equations are presented. (BC)

Explains a projectile motion experiment involving a bow and arrow. Procedures to measure "muzzle" velocity, bow elastic potential energy, range, flight time, wind resistance, and masses are considered. (DH)

Defines learning and memory and presents experimental evidence that indicates that learning and memory are chemical in nature. (JR)

Describes classroom activities using algae, including demonstration of eutrophication, examination of mating strains, and activities with Euglena. Includes on algal morphology/physiology, types of algae, and field sources for collecting these organisms. (JN)

Describes the stages and outcomes of a junior high school science lesson on erosion and deposition utilizing a "kids as researchers" theme. Stages include awareness, discussion, investigation, experimentation, generalization, and extension. (SK)

Describes an approach that uses fiction as a springboard to environmental science experiments and discussions. (JRH)

Features a checklist of structural questions for writing a laboratory report discussion. Presents a rationale for this method of helping students organize their thoughts. (DDR)

To integrate a research/discovery component into one course, an experiment using the sea urchin embryo system is introduced because the teacher manages only one organism and students provide the variables. The materials, handling methods, and experimental methods of the experiment are described. (YP)

Describes the involvement of students in the construction of an inexpensive wooden balance to aid in their understanding of mass. (ZWH)

Describes a simple, relatively inexpensive laboratory activity that allows students to examine the requirements for the fungal decay of wood and devise methods for prevention. (ZWH)

Describes a hands-on activity in which the student's task is to design testing procedures and use appropriate formulas to meet the objectives of a two-dimensional projectile motion lab. (ZWH)

Provides real life assignments that can be used to help students apply chemistry laboratory techniques to solve environmental hazardous waste problems. Numerous diagrams are provided to aid in describing the experiments performed. (ZWH)

Uses extremely strong neodymium magnets to demonstrate several principles of physics including electromagnetic induction, Lenz's Law, domain theory, demagnetization, the Curie point, and magnetic flux lines. (MDH)
