Osmium (Os)

By Wednesday, January 18, 2017 , , 0

Osmium (Os), is a metal found in IUPAC group 8, with a relative atomic mass of 190.2. Just over 12 years ago the BBC1 announced that intelligence agents in the UK and USA had foiled a plot to make a 'dirty bomb' that would have involved the explosion of Osmium Oxide (OsO4). What was slightly unusual about this new article was that it did acknowledge that Osmium Oxide was extremely expensive and only really available to research institutions. In other words, ...

The Examiners Report from the May 2016 Session

The examiners report from the May session is now out. Have you managed to see it / read it? As ever, the report does not ‘look very use friendly’ - it’s just a heap of text! But the contents of it can be quite revealing. The main highlights for me were: 1, The grade boundaries. If I’m honest, I did think they would be lower than this, due to my perception that the course is ‘harder’. In reality, the examinations were not too tricky ...

Colour

Topic 13 is one of my favourites – how do you find it? In this topic, we start to explore complex ions the reasons why these ions are coloured. How do you deal with this topic. I like the fact that it is very visual. It can make a nice transition from topic 3 which is very theoretical –after a couple of weeks of topic 3 theory, the students are usually ready for some lab work! Do you carry out lab work? I like ...

Nh, Mc, Ts, Og

Do these letters mean anything to you?  I expect not so please don’t worry if you have not seen them before. That said, they are the symbols for the most recent addition of elements to the periodic table. To give these new elements their official names (and proton numbers) we have: Nihonium (Nu) – 113 Moscovium (Mc) – 115 Tennessine (Ts) – 117 Oganesson (Og) – 118 What is interesting about the choice of names is that in a change from previous ‘new’ elemental names Ts ...

C3L6 (Cambridge Chemistry Challenge)

Have you heard of the Cambridge Chemistry Challenge? If not, it is definitely worth a look (http://c3l6.com). The website is primarily aimed at UK students in the ‘lower 6th’ – this is equivalent of IB1 but the chemistry itself is very worthy of all IB students and is open to students in the UK and from around the world. In order to fully access the website you will need to register (for free) – if you don’t want to do this though, ...

Seeing Forces

Try asking your physics teacher if this is possible - they will probably give you all sorts of (boring) physics examples – for example, gravity pulling down on a book or a boat floating or an airplane flying. But I can guarantee that none of them well tell you to look at a cup of full water. If you set the following example up correctly, it can be really visual and impressive plus it can teach you a little about Hydrogen bonds ...

Approaches To Learning Flipped

ATL flipped? What an earth does this mean? Last month I wrote a post on the IB’s ideas about how you, the student should approach your learning in class – this is what is termed the ‘Approaches to Learning’ and it forms part of a wider focus on the IB called ‘Approaches to Teaching and Learning’ or ‘ATL’. If you remember, the IB said that you, the student should approach learning using one of five different techniques – Thinking Skills Communication Skills, ...

Approaches To Learning (2)

Last month’s post was focused on Approaches to Teaching and Learning (ATL) with the focus being on the teaching side of things – makes sense doesn’t it? – It applies to us teachers. However, this month I thought I’d throw that logic out of the window and focus on the other side of things – the learning. So how do your students learn? Do you their ‘learning habits’ fit in with the IB’s approaches to learning? And do you facilitate the students ...

How do YOU do it?

Approaches to Teaching, ATL or whatever you call it! – love it or hate it you can’t ignore it. All teachers of the IB programme (whether you teach PYP, MYP, DP or the Career Related Programme) are now expected to teach in accordance with the IB’s ideas on Approaches to Teaching. So how do you go about implementing the IB’s Approaches to Teaching? How do you evidence it? I guess the most important question is ‘What are the Approaches to Teaching?’ The IB has released ...

The New Extended Essay

Were you aware that a new EE guide was out? It has been live for around three months and is for first examinations May 2018, so that will be students whom you start to teach this coming August / September. Now that things have got quieter with IB teaching (IB2 students are finished) I thought it was worth writing about it so that it can inform your planning. The first thing is that the guide is entirely electronic. I am sure that ...
