Genes and Cloning (2006)

Icon: 
DVD icon

There is a lot of controversy around genetic modification of organisms and cloning. This program looks at the way man has modified genomes of plants and animals used for food since the dawn of agriculture. As knowledge of cells and genetics has increased so has man's ability to alter genomes.

DNA: Secret of Photo 51 (2003)

Icon:

On April 25, 1953, James Watson and Francis Crick published their groundbreaking discovery of the double helix structure of DNA, the molecule essential for passing on our genes and the ''secret of life.'' But their crucial breakthrough depended on the pioneering work of another biologist–Rosalind Franklin.

Journey Into Life: Human Reproduction (2007)

Icon: 
DVD icon

This awe-inspiring video shows of the process of human reproduction from conception to birth. It explains how mitosis and meiosis create genetic variation, how the ovum travels from the ovary to the uterus, how sperm pass the cervix, how one sperm achieves fertilization with the ovum, how the zygote begins cell differentiation, and how the embryo grows into a fetus ready for birth.

Energy in Ecosystems (2002)

Icon: 
DVD icon

Any ecosystem needs energy to sustain it, and the organisms within it. This energy comes in massive quantities from the Sun, although only a tiny fraction of the solar energy hitting the Earth goes towards sustaining life. The flow of energy through an ecosystem is complex, and vital to sustaining all life within it.
