School physics
This collection of resources look at many different investigations that can be undertaken with A-level students and covers many required practical pieces of work, alongside other activities which offer alternatives to commonly used work. Lots build on the work students will have done lower down in school and cover lots of apparatus and technique skills too.

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.

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.
