Marked Report
This practical is an investigation into the waves of the Slinky. By oscillating one end of the stretched slinky, a compression moving along it was observed. Changes in the length of the stretch appeared, from observation, to have an effect on the velocity of the moving compression. Stretching the slinky far, seemed to give the compression a...
Loop the loop(free)
This practical is an investigation into the motion of a toy car travelling in a vertical circle (looping the loop) on a plastic track At the top of the track the car has potential energy, as it travels down this PE will be converted into kinetic energy which will be a maximum at the bottom of the slope. As the car climbs the loop this...

Uncertainties
According to the subject guide "an attempt should always be made to quantify uncertainties" in raw data, this implies that the student does not necessarily have to get it right but that they have made a reasonable attempt. There are some simple rules that students can apply but I prefer them to use judgement, provided that they justify...
Marked Report 1
The raw data of velocity and time was in the form of a graph presented on the data studio program, an example from one of the runs for 50g is shown below. Below are tables of the acceleration recorded from the practical. Five runs for the biggest mass then two runs each of the rest due to time constrains. The...
Flying Pig
In this practical the acceleration due to gravity will be found by measuring the time period of a pig flying in a circle. Note: this experiment can also be done with flying cows, dinosaurs and even planes. (With acknowledgement to Mark Headlee UWC USA) The pig flies in a circle because there is a force acting perpendicular to its velocity (towards...

It's not so easy
Posted on 14 May 2013 by Chris Hamper
Luckily our students didn't have to go through the trauma of doing this since they do all their answers on the exam paper but if you have been invigilating or sitting other exams you might have come across this little... more»
How not to pour beer
Posted on 08 May 2013 by Chris Hamper
Last week I did the beer foam decay experiment with one of my first year classes. If a couple of students bring their own lap tops we now have enough computers for one each so instead of using the sticky... more»
Collector of hats

If you are using my text book you may have noticed my interest in hats, The photo shows part of my collection. Actually it shows all of my collection, I'm not doing so well. It started when I hinted to... more»
I will survive
Posted on 30 April 2013 by Chris Hamper
As teachers we sometimes have to do things a little bit out of the ordinary, last week was one of those times. Every two years we have an evening when the teachers put on a show for the students. As... more»
