Phase separation in solid solution upon cooling: laser beam projection
As video 58, but filmed looking into the laser light after it has passed through the vial (i.e. the video is of the laser beam as projected onto a screen): The vial contains a mixture of cyclohexane and aniline cooling from 35°. When the critical temperature is reached and the mixture goes from a single phase to two phases, the spot of light on the screen is disrupted as the phases separate. The spot "flickers" and then becomes totally diffuse. It will eventually form a single spot ag

Phase separation in solid solution upon cooling: vial projection
The vial containing a mixture of cyclohexane and aniline cooling from 35°, has been filmed perpendicular to the direction of the laser light (left to right). When the critical temperature is reached and the mixture goes from a single phase to two phases, the spot of light on the screen is disrupted as the phases separate. The spot "flickers" and then becomes totally diffuse. It will eventually form a single spot again once the transition is completed and the two chemicals have complet

Gene manipulation in plants
Genetic manipulation of crops is an issue of great current interest and controversy. This unit covers some of the basic science that underpins the debate and examines the hotly contested case study of the development of ‘Golden Rice’. By looking at the science 'behind the headlines' you will acquire a clearer idea of both what is possible in GM science and what may be desirable.

1 The circumstances of separation
Most children live with a parent or parents, with siblings and relatives and with family pets in the family home, but many children do not live with their parents or even with their families. They may live elsewhere through choice or necessity, but whatever the event that causes them to move away from their parents or families, the significance of moving in a child’s life can be considerable. This material will be of interest to anyone who supports children who live away from their families in

Parents' responses to the risks
A decade ago, the possibility of a link between the MMR vaccine and autism hit the media. Fear of the vaccine spread rapidly and, despite an almost unanimous consensus that the claim was unfounded, still persists today. In this unit, we’ll examine why this controversy took on such a life of its own and why parents still agonise about the vaccine.

1.5 BSE and risks to human health: vCJD
The furore surrounding the so-called ‘mad cow’ diseases is an important and controversial episode of recent years. Although it peaked several years ago, the topic is still of great medical significance, influencing the way members of the public think about and experience science and scientists.

2.4 Problems and benefits of diagnosis
Most of us have a very vague and narrow concept of what autism is, based mainly on such stereotypes as Dustin Hoffman's character in the film Rain Man. In this unit you will discover that there is a wide spectrum of disorders associated with autism, and an equally wide range of approaches to diagnosis and treatment.

3.7 Hair cell tuning
Hearing is a familiar and important human sense that is a topic naturally of interest to those who are curious about human biology. This unit will enable you to relate what you read to your own sensory experiences – and indeed many of the questions asked have exactly that function. This unit will be best understood by those with some biological understanding.

5.4 Energy budgeting – the benefits of hibernation and torpor
Hibernation is an ingenious adaptation that some animals employ to survive difficult conditions in winter. This unit examines the differences between hibernation and torpor, and discusses the characteristic signs of hibernation behaviour. It explores the triggers that bring on hibernation, and whether internal signals or external season cues are predominant. It also examines the physiological adaptations that occur in hibernating animals. This unit builds on and develops ideas introduced in the

1.2 Discovering the risks
Diabetes is an increasing problem among both adults and children. This unit looks at the way diabetes is managed once it has been diagnosed in order to reduce the risk of further complications. You will look at the role of each member of the team involved in the diabetes annual review and look at the risk factors involved with certain diabetes complications.
