This curriculum provides background information, hands-on activities, worksheets and links to additional sites that teachers can utilize to engage students in formal and informal real-world settings. While some of the lessons build on previous learning, most of the lessons can stand-alone. IPM can be used as a theme in the classroom for an entire year, or as enrichment to regular classroom activities.
