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.

In Chromatography, viewers learn a valuable technique for the rapid separation of chemical mixtures. After the scientific principles of paper chromatography are conveyed through real-life demonstrations and clear graphics, students move into the lab to analyze a number of ink samples, calculating Rf values for the pigments found in each sample. Students investigate the experimental techniques used to determine if two samples are identical by creating a unique visual "fingerprint" of each tested substance. They also explore the factors affecting each separation and extend the investigation by choosing different solvents for the mobile phase. See how gas chromatography is used in arson investigations and how thin-layer chromatography can be utilized to confirm a document's authenticity. Part of the multivolume Science Lab Investigations! DVD Series. Includes a Teacher's Guide.

Students will enjoy connecting batteries, wires and bulbs in various combinations to try to make bulbs light. Snap-on wire clips enable students to make connections between the batteries and bulbs quickly. A chart of various arrangements for connecting the batteries and bulbs is provided. The student studies the chart, predicts which arrangement will light the bulb and which will not, then connects the real batteries and bulbs (following the diagrams) to prove or disprove original predictions. Purchase size "D" batteries separately.
