We all know that throwing rubbish on the ground is littering, so why is letting a balloon float away seen as something different? "Rubber Jellyfish" explores the effects of helium balloons on the environment, wildlife, and human beings. Carly Wilson sets out on a personal journey to meet key players on all sides in the fight to ban balloons, and exposes the confronting truth behind our favourite party product. As she travels around Australia seeking to understand the science and various points of view, Carly discovers a range of issues, from the heartbreaking impact on sea turtles to the potentially deadly effect of helium on children. Her journey takes her from littered beaches to the capital, as she speaks to activists, businesses, and politicians to find out why the balloon problem is being ignored and if something can be done.

While ecosystems face increasing pressure from human activity, science plays a critical role in controlling and minimising harmful effects. This clip explores the role of science and technology in identifying impacts on ecosystems and finding solutions for a more sustainable future. It provides students of biology and other sciences with an excellent overview of this important area of study. Show Less

Every organism lives in an ecosystem. This clip defines and looks at different types of ecosystems, and explores two critical processes that go on within them – energy flow and the cycling of matter. It is ideal for middle to upper level students of biology and other natural sciences. Show Less

Humans have caused massive changes to the natural balance of ecosystems around the globe. This clip examines some of the most dramatic and destructive ways in which people have impacted ecosystems – covering climate change, pollution, deforestation, and introduced species. Middle to upper level biology and other science students will find this an informative and engaging learning resource. Show Less

Our planet has four spheres – the lithosphere, biosphere, atmosphere, and hydrosphere. This clip provides an overview of vital biogeochemical cycles that occur across the four spheres, including the nitrogen, phosphorous, water, and carbon cycles. It is an excellent resource for middle to upper level students of biology and other natural sciences. Show Less

Estuaries… many of us live on or near an estuary and maybe use it for boating or fishing or swimming, or even just for the view. Estuaries are often at the heart of coastal cities. But what’s their story? What’s happening under the water and why are our estuaries increasingly threatened? This programme defines what an estuary is, explains where they are found, and describes the ways that they are formed. It also includes a case study of a typical estuary and how tidal flow, salt water wedging, seasonal change, human use and pollution are effecting it. Show Less

Every cell contains unique structures, each with a specific function. This programme contains engaging visuals and addresses important curriculum content, exploring the structure of eukaryotic and prokaryotic cells. Students will learn about the structure and function of the: cell membrane, nucleus, cytoplasm, ribosomes, rough and smooth endoplasmic reticulum, Golgi complex, mitochondria, lysosomes, chloroplasts, cell walls, and vacuoles. Show Less

In order for an organism to stay alive and function, its cells must be able to exchange certain materials with their environment. That means that within an organism’s body, various molecules and compounds move into, and out of, all cells. This programme explores the ways in which every individual cell, in both eukaryotes and prokaryotes, controls which materials pass in, and out, by the action of its selectively permeable cell membrane. Show Less

Every living thing is made up of cells. The broadest classification of these cells is eukaryotic and prokaryotic. This programme contains engaging visuals and addresses important curriculum content, exploring the similarities and differences between eukaryotic and prokaryotic cells. It is an excellent resource for students studying Science or Biology. Show Less

Australia is home to one of the world’s largest, most complex and amazing ecosystems – the Great Barrier Reef. This video explores the reef’s biotic and abiotic features, including coral formation and how changes in abiotic factors affect it; the food chain, nutrient cycle and carbon cycle; and the impact of human activity. It is an excellent resource for middle/senior students of Geography, Biology and Environmental Science. Show Less

The future of the Great Barrier Reef, one of the world’s most significant marine environments, is under threat due to modern industry and agriculture. Featuring interviews with reef experts, including the director of the GBR Marine Park Authority, accredited reef divers and a Reef Guardians cane farmer, this programme presents an outstanding case study of environmental management for middle/senior secondary students.

What distinguishes plants from other living beings? Why are there so many diverse plants? What is photosynthesis? In this video we will approach the world of plants in order to respond to all of these questions. We will learn about different types of plants and their structure, about how they make their own food and discover how they reproduce. Also, we will understand the importance of these living beings for the balance of ecosystems. Show Less

Cells are the smallest unit of life. All living organisms are composed of one or millions of these tiny cells. In this video, students will explore the inside of a cell to discover what it´s made of and how it works. They will learn about the different cellular functions and how they bring life to all living things. Show Less
