01. CALLING ALL PARENTS!


Calling all parents


Providing resources to help parents understand their kids’ school science education is one of the main aims of Planet Science. And if you’re a parent, you may be interested in helping out with our latest project.

Science Line have been commissioned to produce a booklet all about school science at Key Stage 3. The idea is that the booklet will give parents loads of information about what their children are learning at school. It’ll also include ideas about how to help with their child's homework, explain where to find out more about the actual science involved, and describe activities that can be used to tempt kids into taking more of an interest in science.

Sounds good huh?! All we need though, to make sure that the booklet hits the spot, is some parental input and comments along the way. So if you’re a parent of a child who is currently at KS3 (ie 11-14 year old) and you would like to influence what finally makes it into the booklet, and what it looks like, then please get in touch.
Science Line are looking for a wide range of people, with a diverse range of experience (don’t worry, you don't have to know anything about the National Curriculum). All that you’ll be asked to do is spend a short amount of time looking through each of the drafts and letting us know whether we're getting things right from the perspective of the parents.

Interested? Please email your contact details to caitlin.watson@bss.org with a subject heading of 'parent power'. Once the first draft is ready, you’ll be emailed for your comments.

Thank you for your attention!

02. PHYSICS ON STAGE: GOING DUTCH

Institute of Physics


And so to news for science teachers. The Institute of Physics have been in touch to tell us about ‘Physics on Stage’.

‘Physics on Stage’, if you’ve not heard of it before, is a Europe-wide festival which involves over 300 science teachers from all over, and the idea is that everyone gets together to share ideas, experiences and to watch performances from biology and physics on the theme "Physics and Life".

This year, the event’s taking place in the
Netherlands in November, and you could be there. The UK has been invited to send 30 delegates and to contribute ideas for performances, presentations and workshops. The idea is to share the most exciting and inspirational teaching ideas from each nation, in order to support science teachers and create a strong united force that will, as they put it, “demonstrate to decision-makers and the media that physics and science teaching are worth their attention.”

Kerry Parker is the UK co-ordinator, and, on behalf of the UK National Steering Committee she’s inviting teachers to dive in and get involved.

Fancy it? You can:

Send her your name / school address to receive mailings from the organisers, including a free poster.

 Apply to be one of the delegates

 Suggest workshops, presentations and performances

All you need to do is email
Kerry on kerry.parker@physics.org by 1st April.

... once you’ve done that you’ll no doubt be a bit hungry. But that’s fine – this week’s activity will sort you out.

03. ACTIVITY OF THE WEEK: GROW YOUR OWN FOOD





No, not mustard and cress … but YOGURT. Yogurt is made by culturing some types of harmless (in fact very helpful) bacteria... Jamie Oliver does it, so why shouldn’t you? There are several methods but this is the one favoured by the staff in the Planet Science Diner

You will need:

100 g skimmed milk powder
600 ml hot water
600 ml hot water
1 tbsp plain live yoghurt - (containing either lactobacillus delbrueckii subspecies bulgaricus or streptococcus thermophilus – check the label – don’t use pasteurised yogurt or it won’t work)
2 forks
2 mixing bowls
2 clean glass jars with lids

What to do:

1. Label the bowls A and B and put 50g of skimmed milk powder in each bowl.

2. Slowly stir 300ml of the hot water into a bowl mixing well with a fork.

3. Repeat step 2 for bowl B. Add the tablespoon of yoghurt to bowl A.

4. Rinse both jars with boiling water and label them A and B (be careful not to scold your hands).

5. Pour the contents of bowl A into jar A and close lid tightly. Pour the contents of bowl B into jar B and close lid tightl y - this is your control (well, it is a science activity not a Naked Chef recipe, after all…).

6. Leave the jars in a very warm place overnight - an incubator or an airing cupboard would be ideal. Otherwise, place in a warm spot for four to five days.

7. Compare the contents of jar A and B


What’s going on...?

The yoghurt you added to the bowl of skimmed milk would have contained live bacteria. These bacteria feed on the lactose sugar present in the milk. The lactose is converted into lactic acid, which curdles the milk and gives it the firmer texture and distinct taste that is yoghurt. The acid also stops many nasty micro-organisms from growing.

What to do next:

Let your
eyes and stomach guide you. Pour down drain or... eat!

04. THE SCIENCE AND ART OF PHOTOGRAPHY





If you’re a secondary school teacher working in or around the London area, you should know about a very groovy – and FREE – schools’ lecture which is being held in the Royal Institution on the morning of Monday 7th April.

It’s called
‘The Science and Art of Photography’ and it’s aimed at students at KS3, 4 and early A-level. The lecturers are Tim Hunkin (TV presenter, cartoonist and engineer by training – check out his site http://www.hunkinsexperiments.com for some good ideas) and Adam Goff (Picture Editor at the New Scientist and keen photographer himself).

During the talk, Tim and Adam will explore and explain the
science involved in photography, the history and workings of cameras and current forms of science imagery, including scanning electron microscopes, x-ray and other special photographic techniques.

Of course it wouldn’t be an R.I. lecture if it didn’t feature a wodge of visual and hands-on practical illustrations. So, for example, Tim will be using a camera made of an old suitcase to show the basic principles of cameras and photographic chemistry, and Adam will show a series of images that demonstrate how photography aids the communication of science and he will explain the techniques used.

For further information and to book free tickets, phone
020 7670 2969 or send an email to: schools@ri.ac.uk.

P.S. This lecture has links with the
Novartis and The Daily Telegraph Visions of Science Photographic Awards, which have a special award for students this year.

05. PROGRAM YOUR WAY TO UNIVERSITY


Queen Mary University of London


Opportunity knocks for anyone of a computing nature who’s looking for a free study place at a prestigious university …

Dr Peter McOwan of Queen Mary University of London has been in touch to let you know about a competition they’re running, which could – literally - change your life! The prize is a place on their Computer Science course, ie. a free three years of study, plus a maintenance grant. Not something to be sniffed at.

The competition is Peter says,
“This is a unique and exciting nationwide Internet based Bursary competition primarily for school kids in conjunction with Microsoft. In addition to the course place, the winner will have a fast track to a years work placement with Microsoft, and also a fast track to a coveted full time Graduate position with Microsoft when they graduate.”

Full details are available at http://www.comp.qmul.ac.uk. There are three stages in the competition, and Millionaire-style, they begin nice and easy so you feel dead chuffed with yourself… and if you’re the person they’re looking for you’ll have no problem writing a winning computer program in the final challenge too.

06. SCIENCE BEHIND THE NEWS

http://www.sciencenet.org.uk/slup/CuttingEdge/Mar03/spirit.html


Been watching that mesmerising guy, Derren Brown, on Channel 4 lately? If not, check it out, it’s MORE than intriguing …

Although DB’s ostensibly dabbling with things beyond most people’s ken, his show falls safely within the guidelines of the
Independent Television Commission. But this is not true of some other TV shows about spooky stuff…

Here’s what
Science Line have discovered:

07. RECOMMENDED WEBSITES OF THE WEEK


Following last week’s green-legged amphibian websites, two frog-fans have been in touch to tell us about...

FROGUTS
http://www.froguts.com


http://www.froguts.com


Mike Ryan says, "On this site there is the chance to do a virtual dissection of a frog. At various stages there are explanations, questions etc. I found it fascinating and although perhaps not suitable for all, it is, I believe, a worthwhile activity". Clare Dudman is pretty well in agreement, saying it’s "not for the squeamish, but very educational."

So – have a go, if you think you’re hard enough…

Meanwhile, eyes up for the
Hubble Telescope’s home on the web...

HUBBLESITE
http://hubblesite.org


http://hubblesite.org


Not only is it full of explanations and photos, as you might expect but there are news updates, activities and
‘learning adventures’ (e.g. you can program your own comet to try and hit Jupiter – gentle stuff like that…)

Enjoy!

09. JOKE OF THE WEEK





Weights and measure this week. And technology in the form of a truck.

A man’s driving down the road behind an 18-wheeler. At every red light, the truck-driver gets out of his cab, runs back and bangs on the truck door.

After seeing this at several sets of lights in a row, the car driver follows him until he pulls into a parking lot. When they’ve both come to a stop the truck driver once again jumps out, runs to the back and starts banging on the truck door.

The motorist goes up to him and says, "I don’t mean to be nosey but why do you keep banging on that door?"

To which the truck-driver replies, "Sorry mate, can't talk now, I have 20 tons of canaries and a 10 ton limit, so I have to keep half of them flying at all times."
