This 84 piece jigsaw puzzle is a fun way to help your child develop their understanding of the human body, including the bones, organs and the different functions of your body. Fit the pieces together and study the images to discover how fascinating the human body is. Then attempt the mission cards with different body parts listed on them, identify the sternum, jaw bone and manubrium (we didn’t know it either!). Use the special UV torchlight to locate and reveal what cannot be seen with the naked eye. Very clever!
