Magnetic Fields

 Comparing the magnetic fields to the electric fields around wires as the A level students learn how electricity really works, in fields not by the drifting of electrons.

Making electric fields

 Take a dash of semolina in some olive oil, then add a few volts from a wimshurst machine into two parallel wires and we have an electric field

Maths - revealing the solution

 Revealing the solution one line at a time to show the students how to solve the problem. Their only complaint that I reveal the answer just after they have done that bit. At least they know they are correct so far

Simple Harmonic Motion

Playing with my favourite topic simple harmonic motion today, using a
@pascoscientific force sensor at the top and a protected ultrasonic motion detector below

 

Mounting a force sensor

 We use a Manfrotto friction arm with a lighting stand adaptor to mount the @pascoscientic  force sensor as it gives a degree of movement both vertically and laterally to get the force sensor in the correct position

More capillary rise

 After a significant amount of searching I managed to find a much better capillary rise apparatus. As usual its more expensive but that is the way of all science equipment.

CBA

 CBA  I just Can't Be Asked to balance equations - Summer revision classes for year 10 students who seemed to have missed lots of year 10 chemistry.
