It is a year long curriculum but may be modified to create a shorter module. It consists of fifty activities organized into six sections such as light in water and temperature changes and aquatic habitats. Each section begins with a review of the background material for the teacher followed by process oriented activities for the students. Activities contain objectives, preparation, and an action section which explains how to organize and carry out the activity in general terms. The activities are meant to be generated by guided questions from the teacher with demonstrations and the proper materials provided for the students to use.
Emphasis is placed on discussion groups.
A results and reflection section as well as a conclusion section describe the outcomes that the students should reach. Extensions allow students to study a topic in more detail. Activities include exploring camouflage of underwater organisms, designing a surface dwelling model animal, and examining the effects of nitrates on aquatic microorganisms. At the end of the book may be found a glossary and a set of instructions for making materials and solutions used in the activities.
