In "Hands-On Science Mysteries for Grades 3-6," the authors connect science to real-world situations by investigating actual mysteries and phenomena, such as the strange heads on Easter Island, the ghost ship "Mary Celeste," and the "Dancing Stones" of Death Valley. The labs are designed to encourage the development of science inquiry, in which students will observe, take notes, make diagrams, interpret data, and arrive at solutions, and include extensions for further investigation. After a preface, the book covers 70 mysteries, starting with "The Mystery of the Bed of Nails" and ending with "The Mystery of the Singing Statue." An answer key, list of references, and index are also included.
