Luster, natural, hardness, yield strength, ductile, insulator, brittle, conductor
1.A(an)________________can carry an electric current.
2.Dirt, wood, water are all_______________ materials.
3.The_______________of material affects how easily it can be deformed.
4.Something with a high_______________is very shiny.
5. A very____________ material changes shape without breaking.
6.Rubber is good__________a because it does conduct electricity.
7.A materials_____________ describes how much force it can take before it's permanently deformed.
8. A(an)___________material breaks without much change to its shape.

3. Listen to a conversation between two mechanical engineers. Mark the following statements as true (T) or false (F).
1.The material needs to remain malleable while the machine operates.
2.The woman requests a material with a high yield strength. 3 The man recommends using a metal.


4.Listen again and complete the conversation.
Engineer1:You want something both hard 1____________ right?
Engineer2:Yes. I need to form it into the 2________________. But it needs to stay hard while the machine operates.
Engineer1:That might be a little tricky. It'll be 3______________ in the machine, right?
Engineer2:That's right. So it needs a high 4_________________.
Engineer1:That's hard to find in a 5_______________ . After all, malleability measures how well something bends without breaking.
Engineer2:Yeah, I know. So do you have any ideas?
Engineer1:I would try some 6___________ . It will be malleable when you heat it.

5.Use the email and the conversation from Task 8 to fill out the e-mail.
