1.. A student carries out an experiment to find out the relationship between thechange in length, y, of a spring and mass, m, of the load on the spring. Thearrangement of the apparatus for the experiment is shown in Figure 1. The len gth ofthe spring when a load is placed on the piston is I.

Figure 1

At the beginning of the experiment there is no load. The length of the spring is l0.

The actual length of /0 is shown in Figure 2.

The experiment is repeated by using loads with mass, m, equal to 0.5 kg, 1.0 kg, 1.5kg, 2.0 kg and 2.5 kg. The actual lengths of the spring when the different masses areused are shown in Figure 3, Figure 4, Figure 5, Figure 6 and Figure 7.

Section B : Answerall question

iagram 3.1 and diagram 3.2 show a worker pushing a wheelbarrow on the soft ground. He

noticed that the tyre sinks deeper into the ground when the wheelbarrow is loaded..

iagram 3.1 iagram 3.2

Based on the information and obser ation:

a Stated one suitable inference [1 mark]

b Stated one suitable hypothesis [1 mark]

c With the used of apparatus such as plasticine, weights and other apparatus, describe one

experiment to in estigate the hypothesis stated in 3 b

In your description, state clearly the following

i The aim of the experimentii The ariable in the experiment

iii The list of apparatus and materials.

i The arrangement of the apparatus.

The procedure of the experiment which should include one method of controlling the

manipulated ariable and one method of measuring the responding ariable.

i The way you tabulate the data.

ii The way you analyse the data
