The origin of the decibel scale
Posted by: ozymandias1 on: November 16, 2010
A standard leaving cert physics exam question is “why do we have the decibel scale”? The standard answer is that the range of sound intensities is so large that a second, much more compact scale is required to make the numbers more manageable, and for sound this scale is based on multiples of ten and is [...]
Leaving Cert Physics: Section A Questions and Solutions
Posted by: ozymandias1 on: May 10, 2010
Section A of the Leaving Cert Physics exam contains 30% of the overall marks so it’s worth studying it in detail. I have put together a booklet which contains every Section A question which has appeared on an exam paper at higher and ordinary level together with all the solutions. The booklet can be accessed [...]

Survey finds Physics dropped in 10% of schools
Posted by: ozymandias1 on: April 2, 2010
With all the media attention on NAMA these times it’s understandable that most of us missed this headline from RTE the other day (hat-tip to eagle-eyed Jude for bringing it to my attention). The RTE article leads with the following: Research suggests that almost 10% of second level schools have been forced to drop Physics as [...]

Tom Healy teaches Physics in Cabinteely Community School and for quite a while now has been uploading revision videos on Leaving Cert Physics to youtube. He has almost 50 up there by now and has divided them into Mandatory and Non-mandatory experiments. A wonderful way to revise, but also a wonderful resource for any new teachers. [...]

I posted very few videos on youtube last year, and am determined to rectify that this year, and in particular to put up some clips of Junior Cert classes. Here are a couple on spherical mirrors: The mirrors in this next one were purchased from educationalinnovations for about €20. They have a larger, 22 inch [...]
