Look! No wires. Learning about electricity without wires.

Having attended the Design and Technology Show this weekend at Birmingham's NEC, I came away with an amazing product which I think revolutionises our understanding of electricity and electrical circuits whilst unleashing our creative minds to make some cool things.
It's black and comes in a small jar.
The product is a glue-like paint which just like paint, can be used on any surface you can think of. It dries like glue and is adhesive, which means it can be used to hold things together. However, it also has conductive properties, which makes the product really exciting when combined with electrical components.

As a teacher, teaching electrical circuits to young children often leads to many misconceptions. Whenever we see a circuit presented in a book, very often it's shown as either circular or rectangular. That's difficult to translate into a bulb, battery and a bunch of wires that take on a life of their own.
Over at the Bare Conductive stand I was captivated by Bibi Nelson who demonstrated painting two parallel lines on some paper. She attached an LED light to one end of the parallel lines and placed a 9V battery which straddled across the two lines at the other end. The LED lit as electrical energy transferred through the paint to the LED. Brilliant.

Of course the conductive paint can be used to make any shapes you like and so the concept of a standard rectangular or circular circuit is replaced by an understanding that circuits simply need to be complete and join up.
Not only can the paint be applied to paper, but it can be painted on walls, concrete, glass, fabric and even skin! (though you'll need a pot of Bare Skin instead!) There are numerous ways of connecting the painted surface to buzzers and batteries, perhaps using paper clips, adhesive copper strips, crocodile clips and even snaps for fabric projects.
Bare Paint is very versatile and there are some really cool projects that you can have a go at making on the Bare Conductive website. Take a look for yourselves and see if there's something you think pupils would be equally amazed by.

Skype have started the New Year with a bang and released an updated Skype app for the iPhone which now includes video calling. Video calling has been around for decades now, and 3G mobile phones brought with them video calling too. Unfortunately the video quality was poor and added little value. The iPhone 4 broke new ground with FaceTime, offering iPhone to iPhone calls provided both handsets were on a WIFI network. This is somewhat limiting, but hey.
AirPrint is the new technology that allows wireless printing from Apple iPads, iPhones and iPods..jpg)

When I walked into school this morning I noticed that our Year 5 and 6s have started their technology projects. What was even more inspiring was the paper used to protect the worktops. Large sheets of architectural design plans formed a fascinating backdrop on which the pupils worked..jpg)

This handy little gadget simplifies and stylises the charging of iPhones and iPods in the car. It's tiny and fits almost within the cigarette charging socket itself which is pretty neat. I've owned cars with wires sprawling across seats, wrapped around gearsticks and dangerously tangled around handbrake levers.
This film, directed by Lord Puttnam follows five young people who attend mainstream schools. It highlights how out of touch schools are in providing children with the skills they need in a vastly changing, 21st Century world. We are already a decade into this new Century and yet we are still switching children off of learning..jpg)

Learning Conferences are intended to be a 3-way exchange of information about each pupil from the teachers, parents and pupils' perspective. Pupils are encouraged to attend Learning Conferences as the conversation is centred around them, the learner.

The iPhone travels with me everywhere I go. Most days it gets a lot of use from listening to music, taking photos, checking travel and weather reports, accessing email, diary, administering servers and my home (more on this later!) Some software on the phone drains the battery more than others, such as using it as a phone, or the GPS and Google Maps where data is constantly being downloaded. Often the iPhone struggles to even last the day without a top up or connection to my computer. Some days, this just doesn't happen as I'm constantly moving here there and everywhere.
