Properties and characteristics of materials ~ Activity 2<br />
Objectives<br />
• group materials according to<br />
their properties<br />
• describe and compare materials,<br />
noting the differences in colour,<br />
shape and texture<br />
Working scientifically<br />
• Questioning<br />
• Observing<br />
• Predicting<br />
• Investigating and experimenting<br />
• Analysing (sorting and<br />
classifying)<br />
• Recording and communicating<br />
Background information<br />
Properties of materials are those<br />
characteristics that determine their<br />
suitability for specific applications.<br />
Through this unit, pupils should<br />
extend their knowledge of the<br />
range of materials we use and of the<br />
properties that characterise them.<br />
This knowledge should help<br />
them recognise what needs to be<br />
considered when a material is chosen<br />
for a particular use.<br />
Before the lesson<br />
Materials needed<br />
• Ensure there is a variety of materials or objects available for pupils to observe<br />
and write on the worksheet. They could use additional objects from their desk<br />
and school bag.<br />
Preparation<br />
• Whiteboard the words listed on the worksheet.<br />
The lesson<br />
Stimulus<br />
• Show pupils an elastic band and a wooden ruler. Ask them to describe each<br />
object. Whiteboard the words used. Explain to the pupils that these words are<br />
‘properties’ or special ‘features’ of the elastic band and ruler.<br />
What to do<br />
• Introduce the ‘property’ words pre-written on the whiteboard. Discuss what<br />
each one means and ask pupils to suggest objects or materials to list next to<br />
each one; for example, soft – pillow, cotton wool. Ask them to consider what<br />
the material or object is made from to help work out its properties.<br />
• Encourage pupils to add other describing words to the property list.<br />
• When complete, discuss pupils’ findings as a class. Display completed worksheets<br />
so pupils can more readily compare results.<br />
After the lesson<br />
Answers<br />
• Teacher check.<br />
Additional activities<br />
• Discuss with pupils what the objects or materials listed on the worksheet are<br />
made of and list under each heading. For example, rubber could be under<br />
‘flexible’ and ‘elastic’.<br />
Display ideas<br />
• A cut-out picture montage of materials classified according to properties.<br />
