Practical Activity 14-16

There is a strong tradition of beginning physics with careful measurements of volumes and masses and calculations of densities...

Teaching Guidance 11-14

This activity allows pupils to make some measurements to measure the density of a material for themselves.

Classroom Activity 11-14

To appreciate the idea of density just imagine you can look deep inside a material. If the particles are packed closely...
