Question 24
Densities of some regular objects
In this activity, you will calculate the densities of some different materials, using the mass and volume of regular objects.
You will need: a balance, a calculator, a ruler that can measure in millimetres, some regular objects made from different materials.
Method
1 Measure the length, width and height of each object. You should measure to the nearest 0.1 cm.
2 Calculate the volume of each object in cm³.
3 Measure the mass of each object in grams. Remember to check that the balance is reading 0.0 g before you place the material on the balance.
4 Calculate the density of each material using the volumes and masses that you measured.
5 Record your results in a table.
