RoboEars

The story I come across a lot of science news stories (as you can imagine) and  have noticed that journalists are attracted to certain topics – ones that they think have a certain ‘sexy’ appeal to their readers I imagine. Bionic body parts seems to be one of them – conjuring imagery of a future […]

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 […]

Electrical art

The story Bare paint is an ink which conducts electricity. The paint has been around for a while and has been used to create interactive posters and even to light-up models in a music video. The video below shows how it can be used to create a simple circuit.

Beautiful physics

This video shows an interesting merge of physics and make-up which might just be the hook you need to get certain individuals in your class interested in science (you know who they are!).

Hamster Power

The story Did you know:  The hamster species P.roborovskii have been said to run the equivalent of four human marathons per night? This interesting but apparently useless fact came to my attention via Guardian blogger Grrl Scientist.  The blog post went on to explain the ways that all this kinetic energy could be harnessed to […]

Street lights to face cuts to working hours

The story It seems nothing is safe from the wave of council cutbacks sweeping the nation as Pembrokeshire council has just announced that it is planning to start turning off 14 000 of its street lights in order to save money (and cut down on its carbon footprint).

It's Christmas!!

A very short post today as the pre-chrimbo lethargy is settling in as I suspect it is in most schools across the country. However, I am aware that you may need some lessons to keep the children both entertained and educated so I present you with a couple of Christmas-themed physics lesson ideas which are […]

The crazy world of future electricity generation

With all of the publicity surrounding the BP leak, crude oil is earning a very bad reputation indeed.  Hopefully some good will come out of the tragedy by persuading governments to look more seriously at using renewable sources of energy.

Spinning around

I’m always on the lookout for new toys and gadgets that can demonstrate science in a fun way.  The latest one to catch my eye is the Firewinder.  The helical structure catches the wind, and the turning affect creates electricity which is used to light the LED bulbs embedded in its surface.  It’s a bit […]
