Energy from sources other than fossil and nuclear fuels is to a large extent free of the concerns about environmental effects and renewability that characterize those two sources. Each alternative source supplies energy continuall, whether or not we use it, and most have their origins in energy generated outside the Earth, yet the potential of each is limited by its total supply set against its rate of use. The Sun will radiate energy until it ceases thermonuclear fusion, in around 5 billion years. This unit explores the Sun as a potential source of usable energy.

Has ice ever been discovered on the earth’s moon? What are the benefits of finding water on other planets?
It’s hard to underestimate the importance of water given it covers 70% of the Earth's surface, and makes up well over 50% of the human body but how common is it on other celestial bodies?
The question of whether other planets contain ice and water remains one of the most important lines of inquiry for many scientists working in that field because water can shield us against radiation, in its component forms of hydrogen and oxygen it’s the most powerful chemical rocket propellant known and of course water can sustain life.
The following 4 films examine how much water if any has been discovered on Moons in our Solar System and its implications for science -
This is a one-week residential course which introduces a range of practical skills appropriate to the study of environmental science. You visit a variety of sites where you apply your knowledge of biology, chemistry, earth sciences and physics to study interactions and feedback in the environment, including landforms, soils, water and vegetation. These field studies are supported by tutorials and laboratory sessions in which you analyze your observations and the data that you have gathered; the course includes an introduction to statistical analysis. This material is taken from The Open University course SXR216 Environmental Science in the Field.

“I blame the parents!” How often is that phrase used to explain the ills of society and is it valid? This material will consider how important is quality parenting, who judges it, and is its provision the sole responsibility of parents – should parents just be left to get on with it? It explores what parenting actually means, what is meant by quality parenting and, how it can be enhanced and promoted. It is of interest to anyone who is, might become or works with parents.

The podcast that believes places are powerful agents of positive social transformation.
Join Dean Keith Diaz Moore from the University of Utah’s College of Architecture + Planning as he takes you behind the teaching, research and practice at the leading edge of innovation occurring in our College. Through informal conversations, you will learn the emerging issues, why you should care and what you can do about them to change our world for the better. -
Food is central to our identity. It helps us to define who we are, and our place in our home, our community and our world. It shapes the social interactions in which we engage, with our friends, with our families, and with our community. In so doing, food connects us, to ourselves and to each other.
But contemporary access to food presents some of the most stark examples of human inequality that we witness on a regular basis. All of us need food to survive, day in and day out. Most of us want more from our food than just survival: we seek pleasure in taste, texture, smell and sight. We seek pleasure in sharing food with others. When we walk into a supermarket, we are confronted with a cornucopia of choice from around the world that enables us to seek this pleasure. Most of us have no idea where the food in the supermarket comes from, and most of us give this no thought, focusing merely upon what we need to acquire to seek the pleasure that we want to get from the food that we buy to eat.
We know, of course, that many of us cannot afford to seek that pleasure from food and its sharing, and have to settle for surviving. We know that far too many in our communities cannot afford to make the choices that we can in a supermarket, having to rely upon the charity of food banks to survive. Indeed, many of us face profound difficulties in doing even that. We know that we live in a world in which unparalleled hunger can be found, in places both far and near, as too many simply don't get enough food.
The world food system is designed to enable you to understand how our food system, with its unparalleled abundance and immense scarcity, came to be, unpacking the key factors shaping contemporary production, distribution, access to and consumption of food, both here and elsewhere. After all, if we want the world to become a better place it seems that a good place to start would be on our plates. -
