Demonstration: This rough method can produce a difference of mass of at least 8 g . With enough apparatus it could be done as...
Demonstration: This simple experiment gives a reasonable value for the density of air.
Demonstration: This could be a useful introduction to the idea of density of a liquid.
Demonstration: This method uses an equal-arm balance rather than a domestic spring balance.
Class practical: A simple method for comparing the density of liquids.
There is a strong tradition of beginning physics with careful measurements of volumes and masses and calculations of densities...
This activity allows pupils to make some measurements to measure the density of a material for themselves.
To appreciate the idea of density just imagine you can look deep inside a material. If the particles are packed closely...
For equivalent volumes of substances the statement heavy things sink and light things float is close to being true. However...
