Fibres and fabrics

NATURAL SCIENCES

Grade 4

MATTER, SUBSTANCES AND MATERIALS

Module 54

FIBRES AND PLASTICS

Activity:

To investigate the use of materials, especially fibres and fabrics [LO 1.2.1]

There are different kinds of fibres: those made by man and natural ones made from plants or animals.

What do we call people who design clothes?

The designer has to decide what the use of an article is before they design it. For example, if it is designed for fire fighters it must be made of fire resistant material. If it is to keep people warm it must be of material that insulates well.

Try to obtain small pieces of the following fabrics and paste them in the blocks below. Say where each type of fabric might be used.

Lace:

Denim:

Cotton:

Wool:

Plastic:

Straw:

Velvet:

Rubber:

Lycra:

Be creative and design a special hat for a man who:

1. is doing excavations in a desert;

2. is studying snakes in a steamy jungle;

  1. is working underground in a mine;
  2. is playing the role of a rabbit in a concert.

For each picture say what type of material you will use.

Assessment

LEARNING OUTCOME 1: SCIENTIFIC INVESTIGATIONS

The learner will be able to act confidently on curiosity about natural phenomena, and to investigate relationships and solve problems in scientific, technological and environmental contexts.

Assessment Standard

We know this when the learner

conducts investigations and collects data:

  • notes and remarks on obvious changes or interesting details.

Memorandum

Mr Brain Cell:

People who design clothes are fashion designers.

  • Small pieces of material.
  • Let learners decide for themselves or in groups where these materials will be used.

Hat: Draw a design in each block
