My Body in Motion, Grades 3-5

Give your class a hands-on tour of the body that moves them. This 60-page science pack for grades 3 to 5 focuses on one system only: the bones, muscles, and joints that work together every time a child runs, jumps, throws, or climbs stairs. Nothing here wanders into other body systems, so the whole pack builds one clear story — the skeleton holds you up, muscles pull on bones, and joints let it all bend and turn. Children start by labeling a skeleton and sorting bones by shape, then meet the four joint types and learn how hinge joints bend and straighten. Next they label the major muscles of the arms, legs, core, and back, discover how muscle pairs take turns contracting and relaxing, and see how tendons connect muscle to bone. A build-a-model activity lets them test the idea with straws, string, and a pin before they move on to strong bones, exercise, posture, stretching, and the heart — the muscle that never rests. Practice stays playful and varied: counting sets, sorting muscle or bone, true or false, a vocabulary match, a word search, a crossword, riddles, movement sequences, and a five-minute workout plan children design themselves. Mixed review pages, movement word problems, bone-number puzzles, and two ten-question quizzes check understanding, while a safety page, a muscle-memory page, and a draw-and-label activity round out the student pages. Complete teacher-only answer keys cover every page, and a certificate on the final page celebrates each finished student. Print the pages you need and use them for science lessons, morning work, centers, or homework — no preparation required.
