The following is a list of some of the gadgets and gizmos that Ive found to grab the attention of my</p><p>students. The list here is only a sample of what is available and unfortunately many others can only be on my wish list.The equipment below could possibly be used in Junior Cert, Leaving Cert, and Transition Years or in all three.</p><p>The three sites below are the sources of where this equipment can be purchased over the Internet. Of the three the</p><p>Educational Innovations site was the one I found to be the best, and Klein Bottle to be the best value for the spoutingbowl. I found there were problems with the PayPal method of paying the 4physics site so I ended up wiring the money</p><p>through at an extra cost. All guide prices are in US dollars and are taken from the Educational Innovations catalogueunless otherwise stated. The addresses of the sites are as follows:</p><p> (Educational Innovations site)</p><p> (Chinese Spouting Bowl-well worth a look and cheapest here!)</p><p>Mechanics Optics</p><p>M icro Light Wand:Uses three</p><p>individually coloured LED's, one foreach of the primary colours of light(red, green, and blue) to produce aseries of coloured lighting effects.Instructions are included.

The otherice cube shows no evidence of</p><p>melting whatsoever. Great forshowing the difference in heatconductivity in differentmaterials.</p><p>Guide price: $18.95</p><p>Heat</p><p>Chinese Spout i ng Bow l :Fillthe 38 cm diameter bowl halfwaywith water and rub the handlesvigorously with wet hands.

This hand-held "dynamo" iscompletely visible. It clearlydemonstrates how moving an</p><p>electrical conductor through a magnetic field - a discoverymade by Michael Faraday, can produce electrical energy.</p><p>Guide price: $11.95</p><p>Electromagnetism</p><p>Touch and See Square:Place</p><p>your hand on this black plasticsquare and create a thermalhandprint. Each colour represents adifferent temperature. Can be usedover and over again.</p><p>Guide price: $8.95</p></li></ul>
