|Earth Science at its greatest! The integrated lesson plans in this thematic teacher guide (unit plan) are specifically designed to help fourth, fifth and sixth grade elementary teachers (and their students) explore the fascinating world of geology, from the causes of earthquakes and volcanoes to how to make a fossil. With Part I, teachers use notes photocopied onto overhead transparencies to give students much of the information-based, structured material in the unit. The activities and worksheets included follow closely with the material in the notes. Part II "Optional Lessons" adds flexibility to the unit and suggests lessons which can be coordinated with the main lesson topics, used as enrichment or used at the end of the unit as fun culminating actitites. Teaching earth sciece has never been so much fun!
