Amusing introduction to beryllium
This introduction to the element beryllium (atomic number 4) covers its main uses and properties.  It is very toxic, invisible to x-rays, expensive, and used in some high-tech equipment.  Those working with beryllium are advised not to lick their fingers.  Combines amusing demonstrations with talking to the camera by a wild-haired chemistry professor.  Part of a series called Author(s): No creator set

The Numeral Four

Excellent video for young learners about the number 4.  The words are big enough to be seen in a pre-school classroom. There is no sound--just text and images. Some of the words and images are advanced. (03:05)

3.1 How do organisms take up iron?

Nearly all organisms are able to take up iron. However, only a handful of organisms have had their iron-uptake chemistry studied. The organism that has received most attention (other than human) is a single-cell, prokaryotic bacterium (found in the human large intestine and elsewhere), called Escherichia coli (abbreviated to E.coli), a high-resolution image of which is shown in Author(s): The Open University

Academic research on student engagement - lost formulae to inspiring students
This paper shows academic tutors take on a multitude of roles in their current positions at university and while teaching is expected, from most, it is often assumed that the tutor will apply appropriate pedagogical tools to convey knowledge to the students. This view is now being challenged as many students are being actively encouraged to voice their views of the teaching and learning experience this paper shows

World War I: Germans Attack U.S. Navy Boats
In this History Rewind video clip, take a step back in time to the beginning of World War 1. The repeated sinking of American ships caused President Wilson to declare war. Watch the historic black and white footage of some of the attacks, but there is no sound so it lacks depth.

1.1.5 Late-onset single-gene disorders

An individual might know that a late-onset disease such as Huntington's disease (HD) is present in their immediate family and that they might have inherited the disease gene(s). The problems of genetic testing for HD revolve around the fact that it is pre-symptomatic.

One dilemma is the long delay between testing positive and developing the clinical symptoms of the disorder in middle age. Is it better not to know and live in hope, or as one victim cried ‘get it over, I'm so tir

5 Designer babies?

A character under genetic influence where the distinction between treatment and enhancement is hard to draw is height. Treatment of short stature – with human growth hormone made in genetically manipulated bacteria – has already given rise to controversy about how short a child needs to be for treatment to count as meeting a medical need. That is, how tall is tall enough?

As we identify genes that have effects on many other human characters, from appearance to, perhaps, intelligence

4.6 P is for Provenance

The provenance of a piece of information (i.e. who produced it? where did it come from?) may provide another useful clue to its reliability. It represents the 'credentials' of a piece of information that support its status and perceived value. It is therefore very important to be able to identify the author, sponsoring body or source of your information.

Why is this important?

http://www.yadvashem.org/yv/en/exhibitions/dp_camps_italy/index.asp The exhibition “DP Camps and Hachsharot in Italy after the War”, brings the story of the many thousands of Holocaust survivors in the dozens of DP camps that operated in Italy after World War II. While these camps served as temporary transit stations for the survivors, it was there that they also started to cope with the enormity of their loss, at the same time preparing themselves for a new chapter in their lives with the

2.1.1 The morality play

Before looking at the play's opening scene I should add a brief note on the medieval morality play, the type of drama on which Marlowe draws in adapting The Damnable Life for the stage. After the Prologue and Faustus's long opening speech, you may have been startled by the appearance of the Good and Evil Angels. Even if you had expected to find supernatural beings in a play about a man who sells his soul to the devil, the Good and Evil Angels may have struck you as strange, perh
