How do muscles move bones? Find out using a built-in-class model. Pupils construct a hand model with paper and string, then follow a series of directions to explore the movement process. Discover additional information about the muscular...

Arm your young scientists with knowledge about anatomy as they build their own model of the elbow joint. Help them get a firm grasp on how muscles and bones interact to allow movement as they try different positions for the muscles on...

Like a fresh canvas, stem cells can turn into almost anything. In a comprehensive activity, high school biologists use clay to build a 3-D model of cell division and the processes that occur during the first 14 days of development. Also...
