Today was the first day of NGfL Cymru‘s presence at the Skills Cymru (Cardiff Millenium Stadium) and we were showing ourFree Vocational resources and our links with National Learning Network (NLN) to teachers and students. We were also engaging the children who stopped at our stand with some fun activities, like building walls with Lego bricks, folding napkins (we have learnt many fancy folds today) and building loudspeakers out of plastic and paper cups which were kindly donated to us by Starbucks and Burger King. Unfortunately, McDonalds decided not to be quite so generous and gave us no cups (I was very surprised about that, but maybe they too feel the effects of the Recession). Check out the instructional video on how to make the speakers below.

I have adapted this activity from one of the workshop the Institute of Physics does, i.e. Son of New Ideas. The link takes you to the group about this workshop on TalkPhysics. The IoP version of this loudspeaker is made with cup cake paper stuck at the back of children exercise books and it is a really nice activity, but because there is a lot of noise at the Skills Cymru event we went for a more powerful version and a bit quicker to build!

This activity is really good to get students engaged with Electromagnetic Induction, because they all have speakers and getting to know how they work and make one in few very simple steps brings the Physics to life immediately. They actually were amazed to find out that there really isn’t much more in a commercial speaker than the version they made (well there is a bit more, but the basic principle is the same). They are also finding very interesting to discover that their friends’ speaker is louder than theirs, for example, and they ask a lot of questions about why this might be! This is a good opportunity to use this activity in the classroom, as you could investigate whether the volume of the cup makes a difference in the intensity of the sound emitted, or the number of coils, the material of the cup, etc. And it is a nice opportunity to dig out your data loggers to measure the sound intensity and develop some interesting aspects of How Science Works. I hope you will have as much fun as we at NGfL Cymru are having with this nice idea.

Thanks to IoP for their ever amazing bank of resources and winning ideas!

Yes! The Institute of Physics has reached the Forest of Dean and Gloucestershire. In fact, they have appointed me as Network Coordinator for that area!

Network Co-ordinators are practising physics teachers paid a small honorarium by the Institute to provide support for other physics teachers in their area.  They may organise workshops and short INSET sessions, events for pupils & teachers and help create links & share information between schools etc – whatever is most appropriate really. (See the Teacher Support page on the IOP website: www.iop.org/network for more info).

The modulated laser pen workshop at the Brecon Conference

I am teacher at Croesyceiliog School in Cwmbran and very keen to forge new links around the area of Gloucestershire and the Forest of Dean.  I have a number of tried & tested workshops for teachers (such as ‘Build a modulated laser pen’ and ‘Build a Giant Air Bazooka’ which I blogged about in this blog) and will be developing more according to demand and needs.

So, if you are a Science Teacher involved in the teaching of Physics in the area of the Forest of Dean and Gloucestershire, please help me know a bit more about you by filling in the form in the link below!

Thanks,

I’m really looking forward to working with you,

On the 18th November 2009 a group of Physics teachers from South Wales met in Caerleon School to build giant air cannons out of a 200 litres water butt. I organised the event with Cerian Angharad’s help (South Wales Network Coordinator) and the lovely cakes that Ann Dunster (Head of Physics at the school) provided! All the equipment could be found in Wickes (though the first time I went to buy some of these huge water butts in the Cardiff branch, they told me they either got lost, or stolen… Mmm I still have to figure that one out).

Cutting holes through the butt

These chaps were not very happy when I produced my electric saw after they struggled for 15 minutes to cut their butt with a wood knife, but certainly that’s part of the fun, isn’t it?

This workshop is very useful if you are organising some spectacular activities for your Open Evening. I trialled it in my school (Croesyceiliog School, Cwmbran) and both parents and children loved it. In fact, we filled the giant air cannon with fog from a smoke machine and started shooting at people, who would see these massive smoke circles getting towards them and eventually blasting in their faces! But the fun was not over because we used McFlurry cups and tops to get the children to make their own mini-airzookas. And again the kids loved it, because they could take a little present home that costed nothing to my department, but was good fun for them.

Blasting the cameraman!

The below video shows how you can make you mini-aizooka. All you need to do is going to McDonald and order a McFlurry icecream. The rest you probably have in your house!

But what is the educational value, you might think! Well, there are a number of projects and experiments you pupils could carry out with their mini-airzookas:

1. They could make some observations about what affects the shape, speed and distance travelled by the smoke ring. E.g. by tapping the rubber in different ways, by pulling it and releasing it, etc…

2. They could try to measure the speed of the smoke rings and/or the distance travelled when they tap using more and more force. This activity could generate some very good discussions about reliability of results and method.

3. They could also measure the diameter of the rings at a certain distance from the cannon.

4. A follow on from experiment 2 could be a project were they need to design and build the most reliable tapping mechanism they can. You could even embed this as part of a long term project on electromagnetism, as the children could try to make an eletromagnetic tapper, and so on.

Please, add some more suggestions as comments!
