1. DNA: The Master Molecule Of Life. Colorful animation and microphotography are used in this fifteen-minute program, which examines the way in which DNA acts as the cell's master molecule. Students discover how DNA stores the cell's instructions in the unique biological language called the genetic code and find out how DNA copies itself before cells divide. The concept of the gene is explored and students will follow the flow of information inside the living cell from DNA to RNA to protein. Teachers will find this program to be invaluable in presenting what is often a difficult and confusing subject.
2. Flow Of Matter and Energy In The Living World. This fifteen-minute program for grades 5-9 begins by reviewing basic concepts such as matter, energy, elements, atoms, molecules, chemical bonds, chemical compounds, chemical reactions, and chemical equations. Then by focusing on photosynthesis, cellular respiration, and food chains, students discover how matter and energy flow through the living world.
3. The Living Cell. This program explores the internal organization of cells and explains the function of organelles and other structures in cells.
4. Making New Life: The Basics of Reproduction. This program examines the key processes employed in reproducing living organisms and their cells. Asexual and sexual reproduction is explained. The concepts of haploid and diploid cells are discussed. The processes of mitosis and meiosis are presented. Microphotography and animations are used throughout this valuable teaching tool.
5. The World Of Living Things.
6. The Microscopic World.
7. Molecules and Evolution. This program looks at how biological change takes place at the molecular level in a simple, easily understandable, way. Students learn how genetic mutations occur in DNA. Students discover what can happen to the structure of a protein if just a single base pair in the DNA is altered. They also find out how an incorrect protein can affect the ability of an organism to carry out the chemical reactions needed to support life. The controversial subject of genetic engineering is also explored in this program.
8. The World Of Animals. This program offers a survey of the major phyla of the kingdom Animalia from the simplest sponges to the most complex vertebrates. Special emphasis is placed on evolutionary relationships, bio-symmetry, and methods of animal reproduction.
