Welcome to the de Ferrers Science Blog.
On here Mr Griffiths and other Science staff (and some students – such as the Nutty Professors) will add info, links, videos, pictures, etc. to extend your learning, from basics such as revision help to showing real Science outside the Lab.
You can keep up to date with new science stories by subscribing or following the blog’s Twitter feed @mr_g_defsci.
The song “I can sing a rainbow” – the cause of many incorrect answers in a Physics lesson – has pink.
We can clearly see pink things so there must be pink light…
If you look at the rainbow/spectrum of visible light there is no pink.
This quick Minute Physics video explains why.

A quick video clip covering the origin and meaning of the Cosmic (Microwave) Background Radiation
Minute Physics have many more very useful clips… Go have a look-see…

As recommended by my Year 11 GCSE Physics students – myGCSEscience.com is an excellent site that has video clips on all areas of GCSE science, sorted into modules for the AQA Core Science (B1 C1 P1), Additional Science (B2 C2 P2) and Separate Sciences (B3 C3 P3).
Here is an example from P3 on Convex Lenses
Each video comes with a pdf you can print, with pictures of the slides and spaces for your own notes – so you can build up your own revision guide.
Plus – since all videos are hosted by YouTube – you can use your mobile or tablet to watch them.

Here is a clip on the Life Cycle of Stars put together by the Institute of Physics
Another BBC YouTube clip from Wonders of the Universe – which covers GCSE Physics 2!! – This time on Black Holes.
Professor Brian Cox – teaching you GCSE Physics 2…
The Big Bang made hydrogen – but where did the other 91 natural chemical elements come from? These clips from the BBC’s Wonders of the Universe by Brian Cox answer the questions…
How do we know there are only 92 elements – even out in deep space?
All atoms give out only certain colours – a spectrum – based on how their electrons behave. They also absorb only those colours too. You might have seen this by doing flame tests or looking at gas discharge tubes using a spectroscope.
How did all these elements get made?
Every element in nature was made in stars, during their “life and death” by a process of nuclear fusion which gives out energy up to Iron (so these are made as stars live and die) but needs energy for heavier elements (which means these are made when a star explodes)
Not little stars like ours – but HUGE stars!!

Well – it’s been a lot longer than I thought since the last post – yet still a surprising number of visitors in the last 30 days and from all over the world.
I hope to get back to writing ASAP and maybe rope in a few more student bloggers to keep up the pace.
Finally, a spare moment to get the photos from my camera…
Enjoy the slide show.
The current epoch of time is called by many the Anthropocene. The time of mans impact on the natural world.
This video shows how dramatically our impact on the world has changed since the industrial revolution.
This BBC News article introduces the effects we have had and the views of scientists as to whether we can survive this era.
The Earth system will stabilise again, but under a different set of conditions, which would be a lot less suitable for the whole range of nature that we find today – Professor Will Steffen
