In a senior modern physics laboratory, design" or ingenuity" experiments were introduced to acquaint students with methods of doing complete experiments. The former deals with proposed long term studies while the latter deals with apparatus and short term actual studies. Students rated the design" experiments higher. (Author/TS)

Changes of buoyancy related to temperature of an aluminum block system in water are investigated. Three hypotheses to explain the observed change are developed and tested, and the intellectual processes used in the various steps are noted. (CP)

Reports the reactions of students to an experiment in which all students were guaranteed an A" for one grading period, and lists positive and negative effects on the class. (AL)

Research funded by a grant from the Faculty of Graduate Studies and Research McGill University and by a Canada Council grant. (VM)

Describes two laboratory exercises adopted from current research papers for use in an undergraduate developmental biology course. Gives methods, summary of student results, and student comments. Lists lecture topics, text and reprint assignments, and laboratory exercises for course. (EB)

Describes laboratory experiments designed to demonstrate (1) the properties of cholesteric liquid crystals, (2) thermal mapping, (3) thermal diffusivity, (4) adiabatic expansion of rubber, and (5) measurement of radiated energy by a point source. Contains all of the information on materials and apparatus needed to perform the experiments.…
