🔬 Part 1: Understanding Material Properties

1. Match each property to its correct definition:

Plasticity

Elasticity

Conduction

Insulation

Material returns to original shape after stretching

Heat or electricity moves through the material

Material permanently changes shape when bent

Material doesn't conduct heat well

2. Which of these materials shows elasticity?

Bent paper clip

Stretched rubber band

Plastic ruler that snapped

Clay that was moulded

3. Which materials are good conductors of heat? (Check all that apply)

Metal spoon

Plastic ruler

5. Which spoon got warm first in the hot water experiment?

The _____________ spoon got warm first because it is a good _____________ of heat.

6. How did wrapping the spoon with wool or bubble wrap affect its temperature?

7. Complete this table with your temperature observations:

After 1 minute:

Metal spoon: _____°C Plastic spoon: _____°C

After 3 minutes:

Metal spoon: _____°C Plastic spoon: _____°C

Wrapped metal spoon after 3 minutes: _____°C
