This book presents science learning through in-depth investigation and observation, supporting Next Generation Science Standards (NGSS) in life, earth, and physical science. Each comprehensive unit includes a hands-on engagement activity to allow students to explore and investigate science concepts. The 14 science units build upon prior knowledge and experience and allow students to apply their understanding in a variety of ways. Each unit guides students through exploring the science concept and includes hands-on, cross-curricular activities to extend learning. This robust teaching resource gives you everything you need, including: teacher support pages and an answer key, unit concept page to guide discussion, vocabulary/words to know, reading selections with real-life visual examples, comprehension and vocabulary activities, "I wonder" and research-and-write writing prompts, plus hands-on science investigation that includes experiments, STEM challenges, observations, art projects, and other cross-curricular projects to enhance learning. Topics covered include: Life Science (How Do Animals Use Their Body Parts? What Parts Do Plants Have and What Do They Do? How Do Body Parts Help Animals Grow and Survive? Do Animals Have Babies? Do Plants Have Babies? Are Young Animals and Plants Exactly Like Their Parents? Do Animals from the Same Species Always Look the Same? Do All Roses Look the Same?), Earth Science (Can We Predict Patterns for the Sun, Moon, and Stars? Can We Predict the Pattern of the Seasons?), and Physical Science (What Happens When Materials Vibrate? What Happens When There Is No Light? Where Do Shadows Come From? How Do We Communicate Over Long Distances?). 224 pages
