Electrifying stunt

Magician David Blaine has just completed this latest stunt – to stand on a platform for 72 hours whilst being ‘electrified’ by 1 million volts of electricity.

This video would be good in any lesson on electricity as it demonstrates the use of a Faraday cage in an unusual context. You could show the start of the video where he is getting dressed up in the chain-mail outfit and explain to the class what will happen to him. They can tell you how dangerous they think this stunt actually is and why.

Of course, he was in no real danger of being electrocuted as the metal in the suit conducted the charge and kept it away from his body. The only real risk that his body was under was the fatigue of having to stand up straight with no food or drink for 3 days.

Just in time for Halloween, check out the vampire dinosaur as featured in this week”s newsletter. Can you guess what its fangs were used for? (clue: not biting necks).

Science in the News-letter #25

A rare newsletter this week as it contains not one but four chemistry news stories (plus one physics). Your students can read stories on how pebbles contain evidence that there was once moving water on Mars, how Japanese scientists have created a new element, the news that asteroid dust could potentially halt climate change and how changing your washing powder could help reduce pollution.

 

Science in the News-letter #24

A couple of great astronomy news stories feature in this week’s newsletter: Why astronomers have voted on changing the value of an AU and news about the oldest galaxy so far detected. The latter story would be very useful for a lesson on red-shift. Also included is a video news story about issues surrounding biofuels and a story looking at uterus transplants.

 

 

Science in the News-letter #23

This week’s newsletter features five stories all linked to the GCSE science specifications including: Why classification of a new species of monkey is important to maintain biodiversity, how face shape is genetically determined and how scientists have been able to view the bonds in molecules for the first time.

 

 

Science in the News-letter #22

Snapshot Science’s newsletter is back this week after a summer break. Make sure you download your copy which features a range of news stories from the past week including how ecologists are estimating the population of an endangered tortoise species and news of a new polymer that can be used to replace human cartilage. As usual, all stories have been picked as they have a connection with content from GCSE specifications.

 

 

Science in the News-letter #21

If you are living in the UK then there is no doubt that you are fed up with the torrential rain we are experiencing at the moment. Is this indicative of our future summers? Scientists have announced this week that some extreme weather is due to climate change caused by human activities. However, the rain may not be due to this, we will have to wait a few more years to find out. This story and four others from the news last week feature in this week’s newsletter.

School’s out! (nearly)

As we are coming up to the end of the year I suspect that many of you might be on the lookout for some educational, but fun science lesson ideas. So, I have decided to highlight a few of the ideas that I have written about that might be of use:

 

Teaching science using chocolate

A few fun ideas for experiments using chocolate that always go down well including the popular Brain-choc activity.

What an amazing week for science…

…a healthy pizza has been developed! (oh, and that Higgs thingy)

Sorry – the announcement of the discovery of the Higgs Boson (or is it?) was a truly amazing discovery. Other news this week includes the finding of a well-preserved dinosaur fossil that hints that nearly all dinosaurs were feathered and so even more bird-like then previously thought and the news that the controversial Three Gorges Dam in China has been completed.

 

Would you trust your life to physics?

So, I guess I this should be a post about the Higgs Boson as the announcement yesterday was quite a big deal. However, it’s not for three reasons:

1. There is a lot of stuff on it already out there.

2. Despite spending time yesterday reading several articles and watching videos involving ping pong balls and sugar, I still don’t know enough about it to make a meaningful contribution.

3. I found this video which is amazing: real-life hot wheels!
