Task 1 List the materials you know which are used in engineering. Combine your list with the others in your group and classify the materials as metals.

thermoplastics, etc.

Reading Scanning tables

In engineering it is important to practise reading tables, charts, diagrams, and graphs because so much information is presented in these ways. We will start in this unit with a table.

Scanning is the best strategy for finding information in a table. With scanning.

you know before you read what sort of information you are searching for. To scan a table, you move y o u eyes up and down the columns until you 6nd the word or words you want. To scan quickly, you must learn to ignore any information which will not help you with your task.

Task 2 Scan the table which follows to 6nd a material which is:

1 soft 2 ductile 3 malleable 4 tough

5 scratch-resistant

6 conductive and malleable 7 durable and hard

8 stiff and brittle

9 ductile and corrosion-resistant 10 heat-resistant and chemical-resistant
