The correct Capillary Apparatus. Consists of 6 glass capillary tubes of different inner diameters mounted on a metal frame, in a shallow trough, rather than the base of the capillaries connected to each other and to a reservoir. To demonstrate that water rises to different levels in capillaries of different diameters. Instructions included.

Set against the backdrop of a soccer team in action, Cells takes a close-up look at the smallest living unit in the human body. Kids will discover that, while most cells are very similar in structure and equipment, each type of cell has its own special function. Colorful, detailed graphics give viewers a complete rundown of the various parts of a cell. Inside the cell, they'll see various organelles -- the individual parts that work together to keep the cell functioning. Cell specialization and the process of cellular reproduction known as mitosis are also covered. Includes a fun, hands-on activity that demonstrates the concept of a "selective membrane." One of ten volumes in the Human Body in Action DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library in Action Collection. This title is based on the concepts outlined in the National Science Education Standards for Life Science: structure & function in living systems, reproduction & heredity, regulation & behavior, and diversity & adaptations of organisms. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
