New format: The course is now contained in three books (student textbook, student workbook, and teacher guide). The student textbook starts each chapter with an entertaining written lesson. The lesson is followed by several components in the student Workbook that are intended to reinforce the lesson, address the needs of different learning styles, and engage students in hands-on learning and research. These components include lab sheets, lab reports, problem sets, activities, famous science research assignments, coloring sheets, microscope labs, poetry, and vocabulary review.
