Living organisms inhabit every part of the globe from deep oceans to the freezing poles, scorching Equatorial deserts and lush rainforests. To survive and reproduce, organisms have adaptations that make them suited to their environment. This programme looks at the structural, behavioural and physiological adaptations of some fascinating organisms including arctic foxes, echidnas, humpback whales and camels. Show Less
All forms of life – from simple to complex – share an ability and instinct to reproduce. Reproduction occurs either sexually through an exchange of genetic material between two organisms, or asexually where organisms replicate producing offspring with an identical genetic makeup to their parent. This program looks at sexual and asexual reproduction, starting at the cellular level, with clear explanations of meiosis and mitosis. Using a range of graphics and footage to explain biological processes, it explores various types of asexual reproduction, including fission, budding, fragmentation, spores, vegetative and artificial propagation. Sexual reproduction in animals is covered – including direct and indirect development – as well as sexual reproduction in flowering plants. Finally, various benefits and disadvantages of both types of reproduction are examined. This is an ideal resource for senior level students of Biology and allied subjects, including Health and Human Development. It explains some difficult concepts well, with effective use of visual media. Show Less
This programme explores the need for multicellular animals to have specialised internal transport systems. These are systems that can efficiently distribute materials to and from all parts of the body, providing nutrients to cells and removing waste products. They also provide the vital link with the exchange (respiratory and excretory) systems. The evolutionary aspect of internal transport mechanisms is discussed. Following this is a detailed look at circulatory systems, including the differences between the closed systems of vertebrates and the open systems of invertebrates. Please note: This video contains scenes of an operation. Show Less
This seminal program is widely suitable for senior level primary science, lower secondary science and at an introductory level in Marine Studies university courses. It looks at the basic lifestyles of organisms in the sea. The first three lifestyles are the most fundamental drifters, swimmers and bottom dwellers. The second three are the basis of all food webs producers, consumers and decomposers. These 3 X 3 basic rules give us a fundamental way of understanding how any ocean ecosystem works. Show Less
Life in the Sea explains the distinguishing features of the six most common phyla - from the basic body plans of sponges to the sophisticated anatomy of the chordates. The key points of each body plan are explained and how they equip their owners for survival. After watching this program, students will be able to classify the most common marine organisms at the phylum level. Show Less
This programme shows how all living organisms are classified into five basic categories or kingdoms - plants, animals, fungi, protoctista and monera.
We have updated this popular classic, showing more of Australia’s unique animals. The program features extraordinary footage of kangaroos, emus, platypuses, wombats, dingoes, crocodiles etc, and the only footage ever taken of the Tasmanian tiger. The program also looks at how animals obtain energy, how animals protect themselves, how they protect their young, and survival and extinction of species. This is a wonderful introduction to our unique native species, with exciting activities and suggestions that will keep students enthralled for hours. Show Less
