### Radius of gyration

In this investigation you roll a cylinder down a slope to see how altering the inclination of the slope affects its speed to calculate the radius the gyration (k) from the given equation. This would fit in well to circular motion.

### Photoelectric effect

This is a common investigation using a bulb and coloured filters to determine the value of Planck’s constant (h).  An oscilloscope is required and advice on the settings required are given.

### Ohm’s law

The aim of this investigation is to see the variation of current with applied voltage for two bulbs and compare with Ohm’s Law.  The ones recommended here are a 12V lamp and a small neon bulb.  You can then plot graphs of resistance against voltage to compare the two.

### Newton’s rings

A detailed investigation to measure the wavelength of sodium light.  This could be tied into red shift and the absorption spectrum.  Some specific equipment like a travelling microscope is required but should be accessible for most.

### Moment of inertia of a flywheel

An interesting investigation to see what factors can affect the moment of inertia of a flywheel.  This is good to discuss errors in measurements (such as counting rotations) and would be good to develop improvements.

### Melde’s experiment

This is a standard standing waves investigation, where you hang masses off an elasticated piece of wire/string to see how this impacts the vibrations.  It is good to provide this in the everyday context of a guitar or violin string and you can look at altering the length of the wire or the masses hung on it.

### Mechanical resonance

In this investigation students use a mass of plasticine on top of a hacksaw blade to see how the mass of the plasticine affects the resonance frequency that the blade will vibrate at. This is done by using a vibration generator as well as masses to support the apparatus. This would be a...

### Measuring instruments

This is a good introductory lesson to get students used to using a variety of measuring devices they might be unfamiliar with and which one you would select for a certain job.  The measuring devices are:

• vernier callipers
• micrometer screw gauge
• travelling microscope
• a metre...

### Liquid density using a loaded test tube

For this investigation students will be calculating the density of a liquid (usually water) by using the loaded test tube method.  By adding mass to the test tube, you work out how far it has sunk then by substituting results into an equation, work out the density of the liquid.  This is a good experiment for...

### Lees disc

This investigation is to find the thermal conductivity of a poor conductor in the form of a flat disc.  It is linked to specific heat capacity so follows on well from work done at GCSE, and gives students a good opportunity to test their maths skills using a complex equation.
