The use of a trained sea lion to locate and attach a retrieval device to submerged instruments and test equipment is described. (CP)

Presents an activity that demonstrates a crude method of mapping the sea floor and helps students appreciate some basic considerations that scientists face in working with a project of this type. Demonstrates the logistics of teamwork and the effects of time and cost limitations on science projects. (JRH)

Describes an activity for grade 7-9 students previously introduced to topographic maps and profile lines. Two profiles of equal scale are used to help students appreciate the tremendous size of mid-ocean rift valleys. Procedures and examples of completed profiles are provided. (JN)

Describes a process to develop high school laboratory activities using intertidal ecology of the New England Coast as an example. (MKR)

Focuses on mapping activities designed to provide simulated experiences that help students understand the techniques used to measure and represent underwater terrain without making direct visual observations. (DDR)

Outlines a 10-day unit in oceanography for the primary grades. Suggest stories, chalkboard work, topics for discussion, coloring projects, experiments, films, reference books, and topics for research projects. (CS)

Describes an extended problem-solving activity utilizing drift-bottles that encourages students to deduce probable and great-circle drift-bottle routes, to use logic based on unit calculations, and to estimate the distance traveled and the minimum velocity of these drift-bottles. Includes materials needed, learning objectives, procedures,…

Six paper and pencil activities on marine ecology are presented with answers. Included are a food pyramid, a maze, a find-a-word puzzle, a sea food chain, a crossword puzzle, and a predator-prey puzzle. (CW)
