### Beta ray absorption

An investigation looking at how beta radiation is absorbed when it passes through different thicknesses of aluminum.  From this you can then calculate the absorption coefficient for aluminum.  When doing this investigation please ensure you have followed CLEAPSS guidance or the safety body for your country.  This...

### Parallel plate capacitor

In this A-level investigation you will look at the factors that affect the properties of a parallel plate capacitor.  You can alter the area of overlap or the spacing’s between the plates to see how this impacts on the results.

### Deflection tube

For this A-level investigation students use a deflection tube to measure the specific charge for the electron.  This worksheet provides step-by-step guidance and the calculations that are required to make this measurement.

### Double beam tube

Like the Deflection tube investigation this allows A-level students to measure the specific charge for an electron. It provides a step-by-step guide, along with the calculations that are required to find this measurement.

### Flow of electrical charge

The aim of this experiment is to investigate the velocity of charged ions in an electric field. This is of the same order as the drift velocity of electrons in a wire under the influence of the same field.  A variety of analysis and conclusions that can be draw are provided.

### Frequency of the mains

This simple investigation can be linked to standing waves and builds on work done at GCSE.  In it students look at sending a current through a wire, suspended in a magnet which causes it to oscillate.  From this they can work out the frequency of the mains supply.  They can alter wire length and tension to see if...

### Fresnel Bi-prism

In this A-level investigation students can calculate the wavelength of sodium light using a Fresnel Bi-prism. A micrometre eyepiece is required for this but most of the equipment is readily available, and the worksheet provides simple guidance on how to measure this.

This resource has been provided by Keith...

### Fusing currents in wires

This investigation can be used at GCSE or A-level and is looking at how different factors affect when a piece of wire will break when a current is passed through it. Students can alter the length of wire, the type of wire, the thickness of wire and see how this affects the value of current at which the wire breaks...

### Finding g-linear air track

This investigation uses a linear air track that is tilted to a slope to calculate the acceleration of an object due to gravity.  SUVAT can be used to calculate this value, and datalogging, especially using light gates can be used. Students can also use a protractor to measure angles which can be varied.

This...

### Finding g – helical spring

By using a helical spring and varying the mass on the end of it, students can time the period of oscillation to calculate the acceleration due to gravity.  This can be done by plotting the extension (e) by the time period squared (T2).  This would be good to use computer software to assist with this....

### Finding g – water path in gravity

By using a constant head apparatus or similar you will investigate the shape of a water path projected through the gravitational field of the Earth to find the acceleration due to gravity. This would benefit from using slo-mo filming or photography, or even to introduce students to a travelling microscope.

### Gamma ray absorption

An investigation looking at how gamma radiation is absorbed when it passes through different thicknesses of lead.  From this you can then calculate the absorption coefficient for aluminium.  When doing this investigation please ensure you have followed CLEAPSS guidance or the safety body for your country.

### Geiger tube characteristics

This is a simple investigation where you connect a Geiger Muller tube to a variable voltage supply. You then place an alpha source in front of it and record the count rate for a variety of supply voltages to see how this impacts the count rate.

### GHz oscillations

In this investigation you will use a GHz oscillations transmitter and receiver to see how different factors affect the signal received. The two main ways are altering the distance between the transmitter and receiver, or keeping this distance the same and altering the angle of the transmitter. An example of graphs...

### Half-life dice

This is the classic investigation which demonstrates the idea of radioactive decay and half-life. There are lots of variations of this, but this one looks at using dice and removing those with a number 6. You then plot the graph to work out the ‘half-life’ of the blocks. This is a good investigation to make ...
