The Getting Ready section for each part of the investigation helps you prepare. It provides information on scheduling the activities and introduces the tools and techniques used in the activity. Be prepared—read the Getting Ready section first.

The first item in the Getting Ready section gives an estimated amount of time the part should take. Parts generally take one or two class sessions of 40–50 minutes.

Plan ahead for the scheduling of the parts. Below is a suggested teaching schedule for the module. In addition to the main lesson plans, each investigation suggests additional activities for home and school. Each extension requires additional class time.

The investigations are numbered, and we suggest that they be conducted in that order, as the concepts build upon each other from investigation to investigation. We suggest that a minimum of 8 weeks be devoted to this module. Take your time and explore the subject thoroughly.
