In this fabulous unit, students learn everything they need to know about sound — and more. This highly practical and simple-to-use unit is broken into three parts. First, students participate in meaningful activities associated with the core theme of each lesson. Next, a series of optional lessons provides extra activities that teachers may wish to use for homework assignments, review or enrichment. Finally, a series of student notes provides the information base for the unit and makes expensive textbooks completely unnecessary. This Life Science lesson provides a teacher and student section with a variety of reading passages, activities, crossword, word search, pictograms and answer key to create a well-rounded lesson plan.
