1. Description

The set of five blocks of various densities is used to

determine the densities of different materials and

to demonstrate Archimedes’ principle.

The set consists of five sample blocks of different

materials with identical dimensions plus a

transparent hollow body with internal volume

equal to that of the sample blocks and a loop

attached for suspending it. The sample blocks are

provided with 2 mm holes for suspending them.

2. Technical data

Materials: Wood, aluminium,

iron, brass, copper

Dimensions of each block: 10 × 20 × 45 mm

3. Experiment procedure

3.1 Determining densities of solid bodies

The following additional equipment is needed for

determining the densities:

1 Electronic balance, 200 g (230 V, 50/60 Hz)

U42048-230

1 Electronic balance, 200 g (115 V, 50/60 Hz)

U42048-115

1 Vernier calliper, 150mm U10071

1 Beaker, low shape, from set U14210

3.1.1 Determining density by weighing and

calculating the volume

• Measure the dimensions of the blocks using

the Vernier calliper and calculate the volume.

• Determine the mass m by weighing.

• Calculate the densities of the samples

according to the formula:

=ρ

Note:

The 2 mm holes introduce an error and for precise

determination that must be taken into account in

the calculation.

3.1.2 Determining density by measuring the

buoyant force

• Push about 20 cm of nylon thread through a

hole in the sample block and tie the ends to

make a loop.
